Fiscal Q1 was a quarter of disciplined execution. We delivered Q1 'eighteen revenue and non GAAP EPS above the midpoint of the ranges we provided in October and executed another quarter of strong gross margin and cash flow. We continue to see strength in our software offerings particularly deployments in the public cloud and our services business delivered another strong quarter of revenue growth. 1st quarter revenue of 523,000,000 up 1% year over year was above the midpoint of our guided range of $515,000,000 to 525,000,000. Driven by the recent U.
S. Tax reform legislation, GAAP EPS of $1.41 per share was below our guidance of $1.47 per share was above our I will discuss Product revenue of $227,000,000 in the first quarter was down 5% year over year, and accounted for 43 percent of total revenue services revenue of $296,000,000 grew 7% year over On a regional basis, America's revenue grew 2% year over year and represented 56% of total revenue. EMEA revenue grew 7% year over year and accounted for 27% of overall revenue. APAC, which accounted for 14% of the total decreased 5% year over year and Japan at 4% of total revenue decreased 12% from a year ago. Sales to enterprise customers represented 64% of total sales during the quarter.
Service providers accounted for 20% and government sales were 16% including 8% from US Federal. In Q1, we had 5 greater than 10% distributors. Ingramicro, which accounted for 15% of total revenue, Tech Data accounted for 12% Aero and SYNNEX each accounted for 11% and Westcon accounted for 10% of revenue. Moving on to our operating Non GAAP gross margin was 84.7 percent. GAAP operating expenses of $294,000,000 were within our $288,000,000 to $298,000,000 guided range.
Non GAAP operating expenses were $258,000,000 Our GAAP operating margin in Q1 was 27.1% and non GAAP operating margin was 35.5%. Our GAAP effective tax rate for the quarter was 24 reform legislation. Our GAAP effective tax rate of 38.7 percent was primarily impacted by 2 large non recurring items and estimated creation of undistributed foreign tax earnings and an $11,600,000 impact from the remeasurement of our deferred tax assets due to the change in the reflects the benefits from In Q1, we generated $190,000,000 in cash flow from operations, which contributed to cash and investments, totaling one point $35,000,000,000 at quarter end. DSO at the end of the quarter was 50 days. Capital expenditures for the quarter was $29,000,000 and deferred revenue increased 8% year over year to 991,000,000 We ended the quarter with In Q1, we repurchased approximately 1.24000000 shares of our common stock an average price of $120.73 per share for a total of 150,000,000 Moving to our guidance for as core components of their next generation application architectures.
While this trend has lengthened sales cycles for hardware based solutions with some organization in the middle of this transition. It is driving substantial growth opportunity in both private and public cloud deployments, providing a solid foundation for improving product revenue as we progress through the remainder of the fiscal year and beyond. With this in mind, of $525,000,000 to $535,000,000. We expect GAAP gross margins at or around 83 percent, including approximately $5,500,000 of stock based compensation expense and 2,000,000 in amortization of purchased intangible assets. Non GAAP gross margins are anticipated at or around 84.5%.
We estimate GAAP operating expenses of $296,000,000 to compensation expense and 800,000 in amortization of purchased intangible assets. We expect a GAAP effective rate at or around 25%. We anticipate tax rates to remain at or around these levels for the remainder of And while we are not yet providing tax another small step down in both our GAAP and non GAAP tax rates in fiscal year 2019 and beyond, reflecting full calendar target is $1.66 to $1.69 per share. Our non GAAP earnings target is $2.24 to $2.27 per share. As a reminder, we will be hosting our investor and analyst meeting in New York on March 8th.
And with that, I will turn the call over to Francois.
Thank you, Wendy and good afternoon everyone. During the first quarter, we saw continued momentum with our virtual additions and another strong quarter from our services business. We are increasingly our solutions for help in deploying applications across multi cloud environments. Earlier this month, we we released our annual state of application delivery report. With over 3000 respondents, the report provides a comprehensive view into trends impacting enterprises, service providers and government organizations across the globe.
The results show digital transformation is at the forefront of our customers' minds as they look to optimize their IT infrastructure and evolve how they develop and deliver applications. Multi cloud architectures are taking on growing relevance as most organizations pursue a best of breed strategy for each application deployment. Nearly 9 in 10 respondents reported using multiple clouds, with over half and orchestration to realize leaner IT with the goal of reducing OpEx and better scaling applications to meet user demand. Trends around supporting multi cloud deployments and the growing importance of automation, align with areas where we have in pleased our development investment over the past year. During the first quarter, we introduced per application VE offerings supporting traffic management and web application firewall services, and we made platform enhancements that reduced the boot time and footprint of our software by 50% for public cloud deployments.
These offerings are building blocks for enhanced central management and automation capabilities, we will introduce later this year that support elastic provisioning of ve capacity. Executing in these areas will extend the number of applications we can address, whether these applications reside on prem or in the cloud. Taking a closer look at first quarter results, revenue was above the midpoint of our guided range with strength in our software offerings. We saw a rebound in our EMEA theatre as initiatives we undertook in 2017 to improve execution in this region or paying dividends. We continue to deliver strong profitability and cash generation even as we accelerate our development and go to market investment in software public cloud and security.
We are not satisfied with the current level of product revenue growth, but we are encouraged by improvements in execution and the continued strength in the fastest growing areas of the business And while we have seen instances of our overall appliance revenue was in line with our expectations entering the I Series platform will be a growing part of our appliance mix in the coming quarters. We believe this product family offers compelling performance and customization advantages versus competing offerings and will enable us to take market share in the appliance segment as we progress through fiscal 2018. I Series provides advantages in key use cases for customers, including efficiently managing encrypted traffic and scaling to support high transactional applications such as IoT. We have several significant customer wins in the quarter, driven by the SSL capabilities enabled by I Series. This includes 7 figure deals with the government organization and a large financial services organization, where our ability to efficiently inspect and re encrypt SSL traffic was a clear differentiator over competing offerings.
A large Pan European managed service provider will utilize our hardware, security and IoT protocol capabilities, to support the need inspecting SSL traffic, providing DDoS protection, load balancing and authentication of IoT traffic. F5's ability to innovate around scaling to support bidirectional communication in an IoT environment was a key contributor to this win. During the first quarter, our ve sales grew over 25% compared with the first quarter of 2017. Driving this growth was increased activity within the public cloud from both Bring Your Own License and Utility offerings. We are present within all three major public clouds and providing advanced application services and security across multi cloud deployments is becoming a priority to customers To accelerate growth within the public cloud, we continue to deepen our partner relationships.
In December, we earned Amazon Web Services networking competency designation by showcasing our ability to ensure performance, availability, and security for business critical applications hosted within AWS. This follows our security competency recognition by AWS in October. We joined a select group of partners to meet the qualifications set forth by AWS for technical proficiency and customer success in multiple competencies. As we look to extend our solutions to a broader set of our customers' applications, we are focused on creating more flexibility subscription offerings on large scale and launched enterprise license agreements. Initial customer response to these consumption models has been very positive Our enterprise security momentum remains strong in the first quarter, driven by our WAF and identity access offerings.
We believe we are uniquely positioned application fluency with large complex applications. Our security capabilities are increasingly leading the way in opening new opportunities across our customer base. We continue to expand our application security portfolio across private and private and public cloud environments. Building on our market leading position in WAF, We are partnering with AWS to make our WAF security rules available to our common customers through the AWS marketplace. Today, we announced several new additions to the senior management team.
We are excited to welcome Anna, Kara, Ram and Tom to the F5 team. These additions put into action the plans from the business review process we undertook last year and discussed on our Q4 earnings call. Focus on clearly aligning our product roadmap with customer needs through ADC And Security Business leadership is a key priority that Cara and Ram will drive. Tom will be responsible for driving the business long term strategy as well as overseeing corporate development and our incubation areas, which we will discuss in more detail in We are pleased with our execution To better reach the next tier of applications in the enterprise, we are reducing frictions associated with purchasing deploying and managing are playing across our customer base. Driving improved product revenue growth remains our top priority, and we expect to show progress on this front as we move through fiscal 2018.
In closing, I would like to thank for their efforts during the first
Thank you. Our first question is from Paul Silverstein of Cowen And Company. Your line is open.
Thanks. First one, Andy, from a, I guess, 2 perspectives, one from a macro health and in demand perspective, where it looks like the objective numbers, relative to U. S. Growth, EU growth, etcetera, have been trending up. In a pure lease right now to be quite favorable.
And so there's a favorable economic backdrop. And then in terms of the company's specific issues or product market specific issues, especially relative to the product refresh from a year ago that hadn't transpired and we still don't see the product revenue growth. Picking up. The question being, can you give us more insight more detail on what you're seeing in terms of customer behavior their willingness to spend as well as your particular issues, in the agency market.
Thank you, Paul. So I'll start on your first question as it relates to, Europe. I think you heard that we had some challenges in Europe in 2017, which we felt were linked both to some, macro issues around the environment, Brexit, some uncertainty around regulation. And we also felt that some of it had to do with, our own organization and some execution challenges we were having. Over the last, I'd say, two quarters, we felt the number of these have gotten have moved in the right direction.
So a lot of the macro uncertainties in Europe I think our resolve is more clarity around, Brexit generally the European economies in Continental Europe are doing much better. And so we feel that the macro environment is generally better. And we've made some changes, in our own formation in Europe. We've made some leadership changes. We've also realigned our teams towards the what we perceive to be the best opportunities for growth.
And, as a result, we're doing better. We are really encouraged by the results we saw in Europe this quarter. We're cautious because we had several quarters challenges there, but we're also optimistic about what we're seeing, with our pipeline generally in Europe and our execution. Your second question was on product revenue growth and, generally, the customer behaviors that we're seeing There hasn't been much change on that front since last quarter that we're seeing 2 things specifically on the I Series refresh. Number 1, the adoption of the product continues to be very strong.
It is a very high quality product. Our customers really see actually new use cases for the product and really love performance of the product. So we're continuing to see strong adoption within our customer base for the platform. On the other hand, we're also continuing to see some delays in decision making related to hardware in part because of the complexity of the architectures that our customers are dealing with now, as they move applications across multiple clouds, some in hybrid cloud, some in private cloud, some in public cloud, The variables in the decision making process are just more complex. And we're seeing elongated cycles of decision making.
And that's one of the reasons I think the key reason why we don't think we've seen, the growth acceleration that we would have expected at this point in past cycles.
Yes, Francois, just a quick clarification if I may, on your commentary about things strength in public cloud with respect to enterprises adopting multi cloud architecture. I know you don't quantify it, but I'm asking you if you would be willing to quantify it for the benefit of all
Yes. So we don't quantify it, Paul. I think we've said it is growing fast. These numbers are still small. Relative to our overall revenues, they're growing very fast and we're actually exceeded our own expectations again this quarter in terms the growth we're seeing in our solutions in the public cloud, we'll probably say more about, overall, our public cloud strategy, the solutions we have in there and the traction we're seeing in the public cloud at our analyst meeting in, in March, Paul.
You don't believe there's any cannibalization or meaningful cannibalization?
Actually, I do think so. You have to park that into domains. There are some, applications that are that we support that are moving to the public cloud And generally, we have a very strong attach rate to these applications. But I think in these use cases, it is substantive to something we would have done on prem in the past. So that there's definitely an element of cannibalization or if you will, just a change in deployment model of on prem versus public cloud.
But we're also seeing, net new use cases So we do acquire and we did again this quarter acquired a number of net new logos. So these are companies that had never bought from five before and bought for the first time in our public cloud partners, AWS, Azure or Google. And we're also seeing some, some types of deployments that we would have not had access to before. So a number of our deployments in the public cloud our utility base. This is where our customers are essentially renting at 5 virtual additions for hours.
And we're already billing several millions of hours of virtual edition in public cloud, today. And that's net new incremental for us. That's not opportunities we will have access to before.
I appreciate it. I'll pass it on.
Thank you.
Our next question is from Tim Long of BMO.
Just two for me as well. If you talk about a little bit about the service line, it was very strong again, a little stronger than affected here. Was there any kind of one timers or, anything abnormal with seeing the growth reaccelerate there? And then on the telco vertical, a little bit less than normal seasonal in Q4, could you point a little bit to to what might have held that business back and talk a little bit about the outlook for the telco piece looking out the next few quarters? Thank you.
Yes, Jim, so I'll start with the service line. And I think a couple of things is one, we tend to see seasonally just based on calendar end contracts aligned and things like that. And that helps drive business We also had a program in place for really focusing on going after business in Europe that we felt we weren't focused on enough and actually had a pretty effective quarter in recapturing a lot of maintenance contracts that for lack of a better description slipped through the crack. So Those one time things help drive the strength that we saw. So we'll see that pull back a little bit in Q2 along with normal seasonality, but that's built into the guidance
Yes, this is John De Lulu. Also, I can answer the question about the carriers. We We saw, as per normal, a little bit of lumpiness last quarter, and it didn't come in exactly where we'd expected. But aren't reading anything long term into that and continue to see a lot of activity in both the software and the hardware environments in that vertical.
Great. Thank you.
The next question is from Mark Kelleher of D. A. Davidson. Your line is open.
Great. Thanks for taking the questions. I want to go back to the product revenue probably stick on that a little bit here. The last three quarters, we've seen continued deceleration and in this quarter, despite the I Series kicking into its cycle and strong Europe, we're seeing that deceleration again. So what are the headwinds that you've been facing that that are that you see going away that will allow that top line to grow into next year?
Thank you, Mark. So I think that actually from an I Series refresh perspective, We don't see a change. We think the demand for the product is very healthy, as I said, we're seeing new use cases for the product in, IoT, high transactional applications, etcetera. And we think that's going to continue the longer term. There are though some, product drivers of, product revenue growth that we think are kicking in and probably will accelerate in the second half of the year.
Virtual additions will continue to grow. We expect our public cloud revenues to continue to grow. We continue to see strong demand for our security solutions, in particular, driven by WAF and the increasing trend towards encryption of all traffic, that we deal with. And our SSL capabilities position very well position us very well to deal with that. So security virtual positions in public cloud.
I think we'll continue to be a driver in the second half of the year. And then there's some changes we've made, we talked about our realignment, during our earnings call 3 months ago, there's some changes we've made structurally in our sales channels go to market and some consumption models that we have started offering that we expect to have also an impact going into the rest of FY 2018. So when you factor all of that, I think we feel pretty good about what we've said last quarter, which is continued improvement in product revenue performance throughout the year.
All right. And just as a quick follow-up, the Europe was very strong, but the U. S, the Americas was kind of weak. Was there anything particular going on in the U. S?
No, nothing, I would say nothing in particular. I think the demand in service providers in the U. S. Was it's typically lumpy, but it was weak, this quarter. So you factor all that in, it made up for I'd say a decent performance in North America, but not particularly strong.
I'd say North America enterprise was stronger than North America service provider.
Thank you, Mark.
The next question is from James Fish of Piper Jaffray. Your line is open.
Hey, guys. Thanks for the
question here. Not to keep beating a dead horse, but with product down 5% and it looks like actually on a billings basis, you guys were down as well for kind of the first time in a little while. At what point do you guys think that as we progress through the year, that we could see stability in the product line, if at all, and potentially what concerns you on sort of services billings essentially being down then on a year to year basis?
So I'll take your question on the product and, Andy, we'll touch on the services, James. So on the product first, this was an execution quarter for us, the product revenue came roughly in line with where we expected it to be. As you know, we don't guide product revenue specifically, for the other out of quarters, but the drivers that I have just gone through around software, security and cloud, as well as the initiatives we undertook both on the product and the sales side, give us good visibility into where we think we're going to be going into FY 2018. And we expect, our product revenue performance, to improve sequentially from what we had, in Q1 throughout the rest of FY 2018. I think that's what we said 3 months ago, and we still feel, pretty good about that.
Yes. And then on the services business, yes, because most of our services business revenue is driven by maintenance and renewals. And given where our product revenue has been over the last year and a half, many times we've talked about, we're going to see that pull down our our services billings over time and therefore, the revenue. We think returning to product revenue growth will then pull that back up. So So the year over year, we are seeing it pull down a little bit on a percentage basis.
It was expected. It's directly correlated to our products business. Is how it is. And as Francois said, as we expect to see that improve as we execute through the year, we'd expect to see services pull from that as we return to product revenue growth.
Got it. And then Just a quick clarification. I'm not sure if I've missed it, but did you guys mention what the average deal size was this quarter? I think last quarter it was about 122,000 And then, Andy, any color as to any change in the renewal rates?
Yes. So to the average deal size, this quarter, it was about 113,000, so still within that kind of band that we see. We think a little bit of that seasonality, if you look a year ago. Q1, it was $110,000. We're not seeing any dynamic in the deals combined with that that would lead us to any other conclusion that we're still in that band and we don't think it's pulling up or down deals.
And as far as renewal rates, we saw that tick up because of the cleanup in EMEA, but overall, I'd say it's pretty normal.
The next question is from Jeff Grawal of Nomura Instinet. Your line is open.
Thanks very much. I'd like to change the subject a little bit and get to tax. And part of that, Andy, is for you in terms of what can you tell us about how we should be thinking about the benefits to your free cash flow from the tax reform And then, Francois, for you, to some extent, this gives you an even more powerful balance sheets to work with. What are the triggers that you might consider
what we expect is we'll see as we see the benefit of that through the year, the majority of it we think is going to fall through. Now it's still early days. We're evaluating it against our strategy. But and we'll talk more about this in name. But there's a reality to how we view our business and where how we value our business model and we're going to take all that into consideration.
And we think by March 8th, we'll be able to talk in more detail about what we're going to do with that free cash flow. But again, as I started out, we'll see a lot of that flow through but reluctant to give anything more specific than that right now.
I can tell, yes.
And Geoff, on your on your to the second part of your question, so we will talk more about, capital allocation our Analyst Meeting in March. But I would say this, generally, access to capital has not impacted our capital allocation strategies historically. And I don't expect this tax rate to fundamentally impact our capital allocation strategy. And it has been, and our view will continue to be that we want to return a fair amount of capital to shareholders. And that's been our practice.
I think we have one of the strongest buybacks in the industry. But we've also said that when we have opportunities, for M And A, We won't be disciplined about these opportunities, but if we see opportunities to accelerate things that are strategic to us, we will do that. And that philosophy is not fundamentally changed by, the benefit we're getting from the change in tax legislation.
Okay. Thank you both.
Thanks, Jeff.
The next question is from Alex Henderson of Needham And Company. Your line is open.
Thanks. Two quick questions. 1, just looking at the March quarter guide on the revenues, Is it reasonable to think that the rate of decline in products has hit the trough, in the December quarter is down 5% or is it is it possible that we could see a similar decline or more in the March quarter given it's against a tougher comp And then the second question I had was really on the security side. Dem, I was wondering if you could give us some sense of, is WAF the vast majority of what you're selling in security? And if So it looks like that's becoming more and more of a feature on most of the security platforms that are out there, competition increased and made it more difficult in that space as a result of that, becoming a more widely distributed feature more and more platforms?
Thank you.
Thank you, Alex. I'll take the first one. John will take security. So yes, I mean, if you look at our guidance for the March quarter and you know, you've I think you do a bit of analysis on the midpoint of the guide, etcetera, Yes, it would imply that we have, that the product revenue performance in Q2 will be better than what it was in Q1. And in fact, generally, when we look at our at the progress we have, the pipeline we see in product revenue, the execution we see, we actually do feel we are turning the corner on product revenue growth, in Q2, And frankly, we would be disappointed if we did not return to product revenue growth in the second half of twenty eighteen.
Much easier comps there?
Yes, answering, Alex, answering your question on WAF. So This is a really a great market for us. And as you know, we have a leading product there. We have also very differentiated product, especially in our installed base, which is still a very large market for us to go after. And then we're at as it relates to greenfield opportunities with competition, I think we have some competitive differentiators, but we also have a lot of mobility and our product works on in a multi cloud environment in all the public clouds as well.
And that's one of the fastest areas of growth for us. People trying to standardize their security posture across the multi cloud environment. So it's mostly the, mostly been a positive for us.
So if you haven't seen any erosion in that market or any increased pressures in it as a result of additional competition?
No. I'd say there's a greatly increased demand and some of our competitors are raising awareness and that's generally been a positive.
Thanks for the explanation.
The next question is at of Fort Morgan Stanley. Your line is open.
Hi, good afternoon. A couple of questions for me. First, I'm just wondering with the, kind of bringing some of the customer through service and maintenance contracts had expired back into the fold, if you will, on those. I'm wondering if we should think about that potentially hurting the chances that they will upgrade to the newest versions of product or does that help? Just trying to think about like how that may impact it.
And I guess as part of the improvement in Europe, any evidence from your perspective that the weakening dollar may have helped a little bit either in terms of accelerating close times or expanding product or deal size. Excuse me. And then, I guess my last question is Francois for with appointing of Ram to be Director of Security, can you talk a little bit about how you would like to have kind of what his to do list is and what impact you'd like to see, him have on security and tied to the existing F5 product portfolio. And over what timeframe we should expect that. Thanks a lot.
A slot in there, which
was the first question again.
I'll start with the first one on the service and maintenance. Do we think that hinders cut customers upgrading. And John can add on to this if he has additional commentary from his perspective, but we really this was a program put in place because we think we lost a little focus there. This wasn't anything more than smaller deals were just not getting addressed. We regrouped the team.
And where they thought they were lost, we said they're not lost go after them and get renewals. And when we renew, we can capture the revenue for the period of time that's gone by between the expiration of the contract and the renewal. And we think that was the main driver there, not anything that you could correlate that that's directionally how they might be thinking about upgrading their equipment.
But I would add to that, that it's a very it's very powerful from a sales go to market perspective to continue to have that commercial relationship with those customers. It doesn't inhibit future sales. In fact, it gives us lots of visibility into the challenges our customers are having and really sets up the next generation sale. So it's hugely positive to have a high renewal rate for us.
Yes. And then on the foreign currency, could that be helping us? I mean, clearly because we bill internationally merely in U. S. Dollars.
It makes our equipment more affordable. Anecdotally, I'm not hearing anything that would say that's driving business. I would contend this really is more about projects that were delayed as they worked their way through everything going on from Brexit to GDPR and it's getting to the point where it's freeing up again. So I wouldn't correlate those 2 things personally.
And then the to the second part of your question, James, on so Ram and his priorities, firstly on his background, Ram has a long experience in the security industry. Both with more traditional security companies and more sort of next generation cloud oriented security companies. And so he has a very broad perspective of the industry, and that is going to be very valuable for us because In security, we have no shortage of opportunities. And a key part of the mission for RAM is to really prioritize the opportunities that we go after. One of the immediate elements of what REM is working on is we have been quite successful selling security attached to our ADC.
And we see opportunity more and more and demand from our customers to take on some of our stand alone security offerings. That would appeal more to a sec ops buyer. And so Ram's looking at what's the best way to capture that opportunity and which offerings should be first. Versus offerings that would follow on later. And that's an immediate priority.
And then more broadly, in the space of application security, we're seeing a lot of new complexities emerge. Those were validated again by our the research we did in our state application delivery report where we're seeing that as people adopt more and more multi cloud environments, their confidence in security solutions is actually decreasing. And really, there's an opportunity to emerge as a partner to solve these new complexities, where we start in this journey to multi cloud application security, again, is a set of priorities and investments that RAM is going to define for us.
That's great. Thank you so
The next question is from Michael Genovesi of AKM, MKM Partners. Your line is open.
Thanks a lot. Can you help us quantify some of these things in security, for instance, security applying to tax rates on do you have any kind of metric we contract there And even more importantly, standalone security sales as a percentage of revenue, and are we targeting that to grow over time? What can you share with us there? Hi,
Mike. So the last question is, is it yes, we are targeting loan security offerings to grow over time. So the first part, no, we don't break that out. I can tell you an important portion of our security or even of our ADC business is driven by security. And I would say qualitatively that that portion of the business that's driven by security is growing, every quarter.
The other data point I'd give you is that, as our public cloud business grows, the security attach rate in the public cloud is about double what it is on prem. And that's because of the complexities of securing applications in the public cloud. So that's as far as I'll go as far as quantifying our security business, generally, the trends are are up and more important for us.
Okay. That's fair. Thanks, Francois. And then you just hired a new strategy, corporate development manager. And so my question is, how do you think he can and his team can help you drive the top line growth of the company.
And do you think security will kind of be a over weighted portion of that?
Yes, Mike. So there are multiple responsibilities for Tom Fountain, who's joined us last week as our chief strategy officer. One is we have initiated a number of incubation initiatives where we're looking at, new developments that would have, potentially long term growth opportunities for F5. And these are under Tom, in part, this Tom has also a background in venture capital and can help relationships with a number of companies with whom we have partnerships in the IT space. And these partnerships are actually quite important for the top line, because we co market, we co sell, we do certifications, we are integrated in their environments, whether it be SDN environments or next generation IT architectures.
And so those partnerships are key to short term revenues. And Tom's going to help drive that with the business development group. And then the last portion of Tom's responsibilities is, in fact, corporate development. And in that, Tom, has the experience to help us with the build versus buy decisions that we think we will be making as we assess opportunities, insecurity and elsewhere around developing our portfolio.
Okay. Thank you, Francois.
Operator, I think we'll take one more question.
Certainly, the next question is from Chaseen Nolan of Baird. Your line is open.
Okay, great. Thank you. Francois, I wanted to ask about your comment on architectural change causing decision making delays. Public cloud isn't new and SaaS isn't new. So maybe there's an inflection point that's happened of late, but could you talk to that statement a little more?
Yes. So what we've seen is, a number of customers are when they're making decisions, and this comment was specific to refresh cycle on I Series, and specifically on hardware purchases, where we're seeing a number of customers before making these decisions as part of the decision making cycle undertake a review of what assets do they want to have, where you will see that one thing that has changed year on year, and we've reported on that in the state of application delivery report. Is that customers are embracing multi cloud. And as part of that, they're having a sort of best cloud for the app strategy. So they're making decisions on where an app is going to reside on a per app basis in cloud versus non cloud.
And as they go make these decisions and have to make significant commitment on infrastructure assets, that decision making cycle is elongated cloud is not new. You are correct about that, but I think, multi cloud and per app decision making around multi cloud is a trend that we are seeing becoming reality. For us, frankly, while this has given, I would say, short term headwinds specifically on hardware. And as we said, I think last quarter, we didn't see on hardware the uptake that we would have seen at this type in the cycle. Overall, we think over the long run, it bodes very well for us because we feel that we're probably uniquely positioned to serve these needs across multi cloud environments, with our hardware, on premises, our software on premise and increasingly our software in the public cloud with multiple consumption models across all these environments.
There aren't, there isn't any other company that really has this breadth of offerings, for supporting these multi cloud strategies.
Okay. And then to finish things up, you've called your growth areas cloud security and then virtual additions. Which of those is receiving the most investment or which offers the most opportunity, across those 3?
So that's a good question. So there are different stages of of growth. I would say our virtual edition, software is already a meaningful business for F5 and we where we continue to shift more investments in that direction. Security also, I think is at scale for us at F5. Public cloud is more nascent.
So in terms of growth in investment, public cloud probably has the highest growth of investments in these areas, but the 2 other areas or if you will, larger to date, and with increasing investments year on year.
Okay. Thanks a lot, Francois.
Thank you.
Thank you everyone for participating today. We hope that we see many of you in New York in March. And thank you.
And that concludes today's conference. Thank you for your participation. You may now disconnect.
