‘Hypervisity’ Rages On

Competition in the hypervisor space is vigorous these days

We've tracked a trend for the past several years: customers aren't moving to standardize on a single brand or type of server, operating system, or even x86 hypervisor. But, in our in fifth annual x86 Data Center Survey (2011-‘12 edition), we were somewhat surprised to find that customers were using a wide range of different hypervisors to a greater extent than we anticipated.

The total number of respondents in our survey was 345, with 40% of respondents in mid-size and large organizations of 4,000 employees and above. This was a global survey; 46% of respondents hailed from Europe, 40% from North America, and 11% from Asia/Pacific. Respondents came from our Gabriel Consulting Group survey data base of previous participants and from targeted advertising.

Just over 80% of the IT shops in our survey are using VMware on at least some systems in their infrastructures. The company held roughly the same percentage of usage in both the 2009-'10 and 2011-'12 editions of our survey.

While VMware is the most prevalent, the company doesn't have a lock on the enterprise hypervisor market; other mechanisms are getting plenty of use as well.

Microsoft's Hyper-V product is the second most widely used hypervisor - around 40% of our enterprise data center respondents use it on at least some systems. This percentage has held roughly steady over both survey periods.

The major Xen variants from Citrix and Oracle are used by 32% and 21% of our survey respondents, respectively. These percentages are virtually the same in both our 2009-'10 survey and in our latest 2011-'12 edition.

The only virtualization mechanism showing growth overall is KVM, which moved from 31% to 33% prevalence in our two surveys. This clearly isn't a huge jump, but it's more than we've seen for other solutions.

Standardization of Hypervisor Platforms
Looking beyond which virtualization types are used, next we analyzed standardization on a particular hypervisor technology. We were able to trend this data as well. Again, VMware dominated but we detected more customers committing to KVM and Hyper-V as their "go-to" hypervisor technology. Let's review the numbers.

VMware has become slightly stronger in terms of being the standard virtualization solution for our enterprise data respondents, moving from 55% to 57%. But the magnitude of VMware's sizeable lead obscures the moves in the back of the pack.

We examined the same data, but with VMware removed to more clearly highlight the changes in standardization rate among the other hypervisors.

Customers standardizing on Oracle's version of Xen moved from 2% to 3% during the two survey periods. For Citrix Xen, we see a small drop from 4% to 3%. Both of these changes are probably due to differences in the survey respondent bases.

But when it comes to KVM and Microsoft's Hyper-V, we do think that we're seeing real growth. The number of customers who use Hyper-V as their standard solution more than doubled, moving from 3% to almost 8%. KVM also saw its customer standardization rates double from 3% to 6%.

Examining KVM's Growth
In fact, KVM is the only hypervisor in our last two surveys to notch gains in both the number of overall users and in the number of users adopting it as their standard go-to hypervisor.

These are modest gains to be sure, with overall usage increasing by 2% and standardizers growing from 3% to 6%.

While this isn't what we'd call "house on fire" growth, it's certainly a positive development for KVM and, given other KVM-related activities, might signal the beginning of a growth spurt.

We believe KVM capabilities have come a long way in the past several years, with support for a wide range of Linux, Windows, and even Unix guest operating systems. KVM also provides some of the most popular features of VMware and Xen, like live migration and the ability to host large (up to 16 CPU) SMP guest instances.

It's noteworthy that KVM is different from the others in a couple of crucial ways. It's the only hypervisor that's actually part of Linux and it uses the Linux scheduler and memory manager. Both VMware and Xen are external hypervisors and therefore need to have control mechanisms for the entire system, making them larger and more complex.

Summary
Despite VMware's big lead, competition in the hypervisor space is vigorous these days. Microsoft is using their heft to drive Hyper-V into their sizeable installed base. Commercial and open source Xen and KVM variants give customers alternatives that are technically sophisticated and also available as fully supported packages.

Our survey clearly shows that rather than selecting a single hypervisor and virtualization suite provider, customers are picking and choosing what they feel are the best tools for their unique needs. The more competition we have in this or any other market, the better the resulting products. Go here if you are interested in seeing more details on our report.

How is DevOps going within your organization? If you need some help measuring just how well it is going, we have prepared a list of some key DevOps metrics to track. These metrics can help you understand how your team is doing over time. The word DevOps means different things to different people. Some say it a culture and every vendor in the industry claims that their tools help with DevOps. Depending on how you define DevOps, some of these metrics may matter more or less to you and your team.
For many of us laboring in the fields of digital transformation, 2017 was a year of high-intensity work and high-reward achievement. So we’re looking forward to a little breather over the end-of-year holiday season. But we’re going to have to get right back on the Continuous Delivery bullet train in 2018. Markets move too fast and customer expectations elevate too precipitously for businesses to rest on their laurels. Here’s a DevOps “to-do list” for 2018 that should be priorities for anyone w...
If testing environments are constantly unavailable and affected by outages, release timelines will be affected. You can use three metrics to measure stability events for specific environments and plan around events that will affect your critical path to release.
In a recent post, titled “10 Surprising Facts About Cloud Computing and What It Really Is”, Zac Johnson highlighted some interesting facts about cloud computing in the SMB marketplace: Cloud Computing is up to 40 times more cost-effective for an SMB, compared to running its own IT system. 94% of SMBs have experienced security benefits in the cloud that they didn’t have with their on-premises service
DevOps failure is a touchy subject with some, because DevOps is typically perceived as a way to avoid failure. As a result, when you fail in a DevOps practice, the situation can seem almost hopeless. However, just as a fail-fast business approach, or the “fail and adjust sooner” methodology of Agile often proves, DevOps failures are actually a step in the right direction. They’re the first step toward learning from failures and turning your DevOps practice into one that will lead you toward even...
DevOps is under attack because developers don’t want to mess with infrastructure. They will happily own their code into production, but want to use platforms instead of raw automation. That’s changing the landscape that we understand as DevOps with both architecture concepts (CloudNative) and process redefinition (SRE). Rob Hirschfeld’s recent work in Kubernetes operations has led to the conclusion that containers and related platforms have changed the way we should be thinking about DevOps and...
While walking around the office I happened upon a relatively new employee dragging emails from his inbox into folders. I asked why and was told, “I’m just answering emails and getting stuff off my desk.” An empty inbox may be emotionally satisfying to look at, but in practice, you should never do it. Here’s why. I recently wrote a piece arguing that from a mathematical perspective, Messy Desks Are Perfectly Optimized. While it validated the genius of my friends with messy desks, it also gener...
The goal of Microservices is to improve software delivery speed and increase system safety as scale increases. Microservices being modular these are faster to change and enables an evolutionary architecture where systems can change, as the business needs change. Microservices can scale elastically and by being service oriented can enable APIs natively. Microservices also reduce implementation and release cycle time and enables continuous delivery. This paper provides a logical overview of the Mi...
The next XaaS is CICDaaS. Why? Because CICD saves developers a huge amount of time. CD is an especially great option for projects that require multiple and frequent contributions to be integrated. But… securing CICD best practices is an emerging, essential, yet little understood practice for DevOps teams and their Cloud Service Providers. The only way to get CICD to work in a highly secure environment takes collaboration, patience and persistence. Building CICD in the cloud requires rigorous ar...
The enterprise data storage marketplace is poised to become a battlefield. No longer the quiet backwater of cloud computing services, the focus of this global transition is now going from compute to storage. An overview of recent storage market history is needed to understand why this transition is important. Before 2007 and the birth of the cloud computing market we are witnessing today, the on-premise model hosted in large local data centers dominated enterprise storage. Key marketplace play...
The cloud revolution in enterprises has very clearly crossed the phase of proof-of-concepts into a truly mainstream adoption. One of most popular enterprise-wide initiatives currently going on are “cloud migration” programs of some kind or another. Finding business value for these programs is not hard to fathom – they include hyperelasticity in infrastructure consumption, subscription based models, and agility derived from rapid speed of deployment of applications. These factors will continue to...

We seem to run this cycle with every new technology that comes along. A good idea with practical applications is born, then both marketers and over-excited users start to declare it is the solution for all or our problems. Compliments of Gartner, we know it generally as “The Hype Cycle”, but each iteration is a little different. 2018’s flavor will be serverless computing, and by 2018, I mean starting now, but going most of next year, you’ll be sick of it. We are already seeing people write such...
Defining the term ‘monitoring’ is a difficult task considering the performance space has evolved significantly over the years. Lately, there has been a shift in the monitoring world, sparking a healthy debate regarding the definition and purpose of monitoring, through which a new term has emerged: observability. Some of that debate can be found in blogs by Charity Majors and Cindy Sridharan.
It’s “time to move on from DevOps and continuous delivery.” This was the provocative title of a recent article in ZDNet, in which Kelsey Hightower, staff developer advocate at Google Cloud Platform, suggested that “software shops should have put these concepts into action years ago.” Reading articles like this or listening to talks at most DevOps conferences might make you think that we’re entering a post-DevOps world. But vast numbers of organizations still struggle to start and drive transfo...
Let's do a visualization exercise. Imagine it's December 31, 2018, and you're ringing in the New Year with your friends and family.
