In 2012, I wrote a blog titled Private Cloud: 'Everyone's Got One, Where's Yours?' which looked at the perception of private cloud versus the reality of the environments that carry this name. Although reported interest and adoption were high, most environments fell short of the basic characteristics of cloud. Almost 1.5 years later, Forrester continues to see interest in and reported adoption of private cloud -- according to Forrester's Hardware Survey, in 2014, 55% of North American and European enterprises plan to prioritize building an internal private cloud, and 33% already having adopted private cloud. Despite the increased awareness in private cloud shortcomings, Forrester found that only 1/4 of these "private cloud" environments establish self-service access for its users. What's most interesting is that most of these enterprises aren't looking to private cloud for cloud-specific benefits.
In 2011, my colleague James Staten and I published two light-weight vendor assessments on the private cloud and public cloud market. These solutions sit at the extremes of the IaaS market. To kick off 2013, I published a full vendor evaluation of a market that sits in between these two IaaS deployment types — hosted private cloud. Forrester's Forrsights Hardware Survey, Q3 2012 showed that 46% of enterprises are prioritizing investments in private clouds in 2013. While slightly more than half plan to build a private cloud in their own data center, more than 25% said they prefer to rent one. Hosted private cloud opens the door to a variety of benefits: 1) You reach cloud from day one. 2) Compute is dedicated from other clients. 3) It can enable future hybrid scenarios. 4) Easier-to-meet licensing and compliancy requirements. 5) Outsourcing the setup of the cloud and management of the infrastructure to focus on support and utilization.
Overall this report revealed no leaders, but it did show some strengths and weaknesses across the market and provide framework and sample criteria to assess vendors within this space. This research process also revealed some unexpected nuances within this space:
Hosted private cloud and virtual private cloud are often used interchangeably within the market — despite being distinct deployment types.
Level and method of dedication varies greatly by solution.
Layers managed differ greatly by solution.
Although agility is a benefit, few enable self-service access to resources to its end users. Ticket-based request systems are common.
Many enterprises are using hosted private cloud for some unexpected advantages:
Hybrid clouds are especially subject to the law of unintended consequences, says Forrester’s cloud expert James Staten. Many IT organizations don’t even acknowledge that they have a hybrid cloud. The reality: If enterprises are using public cloud software-as-a-service (SaaS) and/or deploying any custom applications in the public cloud, then by definition they have a hybrid cloud, because it almost always connects to the back end.
In this episode of TechnoPolitics, James implores CIOs and IT professionals to get serious about hybrid cloud now to avoid spaghetti clouds in the future.
To publish this post, I must first discredit myself. I'm 42, and while I love what I do for a living, Michael Dell is 47 and his company was already doing $1 million a day in business by the time he was 31. I look at guys like that and think: "What the h*** have I been doing with my time?!?" Nevertheless, Dell is a company I've followed more closely than any other but Apple since the mid-2000s, and in the past two years I've had the opportunity to meet with several Dell executives and employees - from Montpellier, France to Austin, Texas.
Because I cover both PC hardware as well as client virtualization here at Forrester, it puts me in regular contact with Dell customers who will inevitably ask what we as a firm think about Dell's latest announcements to go private, just as they have for HP these past several quarters since the circus started over there with Mr. Apotheker. Hopefully what follows here is information and analysis that you as an I&O leader can rely on to develop your own perspective on Dell with more clarity.
Complexity is Dell's enemy
The complexity of Dell as an organization right now is enormous. They have been on a "Quest" to re-invent themselves and go from PC and server vendor, to an end-to-end solutions vendor with the hope that their chief differentiator could be unique software to drive more repeatable solutions delivery, and in turn lower solutions cost. I say the word 'hope' deliberately because to do that means focusing most of their efforts around a handful of solutions that no other vendor could provide. It's a massive undertaking because as a public company, they have to do this while keeping cash-flow going in their lines of business from each acquisition and growing those while they develop the focused solutions. So far, they haven't.
Now that we’ve been back from the holidays for a month, I’d like to round out the 2013 predictions season with a look at the year ahead in server virtualization. If you’re like me (or this New York Times columnist), you’ll agree that a little procrastination can sometimes be a good thing to help collect and organize your plans for the year ahead. (Did you buy that rationalization?)
We’re now more than a decade into the era of widespread x86 server virtualization. Hypervisors are certainly a mature (if not peaceful) technology category, and the consolidation benefits of virtualization are now uncontestable. 77% of you will be using virtualization by the end of this year, and you’re running as many as 6 out of 10 workloads in virtual machines. With such strong penetration, what’s left? In our view: plenty. It’s time to ask your virtual infrastructure, “What have you done for me lately?”
With that question in mind, I asked my colleagues on the I&O team to help me predict what the year ahead will hold. Here are the trends in 2013 you should track closely:
Consolidation savings won’t be enough to justify further virtualization. For most I&O pros, the easy workloads are already virtualized. Looking ahead at 2013, what’s left are the complex business-critical applications the business can’t run without (high-performance databases, ERP, and collaboration top the list). You won’t virtualize these to save on hardware; you’ll do it to make them mobile, so they can be moved, protected, and duplicated easily. You’ll have to explain how virtualizing these apps will make them faster, safer, and more reliable—then prove it.
On Tuesday, September 4, Microsoft made the official announcement of Windows Server 2012, ending what has seemed like an interminable sequence of rumors, Beta releases, and endless speculation about this successor to Windows Server 2008.
So, is it worth the wait and does it live up to its hype? All omens point to a resounding “YES.”
Make no mistake, this is a really major restructuring of the OS, and a major step-function in capabilities aligned with several major strategic trends for both Microsoft and the rest of the industry. While Microsoft’s high level message is centered on the cloud, and on the Windows Server 2012 features that make it a productive platform upon which both enterprises and service providers can build a cost-effective cloud, its features will be immensely valuable to a wide range of businesses.
What It Does
The reviewers guide for Windows Server 2012 is over 220 pages long, and the OS has at least 100 features that are worth noting, so a real exploration of the features of this OS is way beyond what I can do here. Nonetheless, we can look at several buckets of technology to get an understanding of the general capabilities. Also important to note is that while Microsoft has positioned this as a very cloud-friendly OS, almost all of these cloud-related features are also very useful to an enterprise IT environment.
New file system — Included in WS2012 is ReFS, a new file system designed to survive failures that would bring down or corrupt the previous NTFS file system (which is still available). Combined with improvements in cluster management and failover, this is a capability that will play across the entire user spectrum.
Last year, my colleague, James Staten, and I published evaluations of the (internal) private cloud and public cloud markets — this year we’re going to fill in the remaining gap in the IaaS space, by publishing a Forrester Wave evaluation on Hosted Private Cloud Solutions. Vendors participating in this report will be evaluated on key criteria, a demo following a mandatory script, and customer references for validation of the solution. Throughout the research process I’ll be providing some updates and interesting findings before it goes live in early Q4 2012.
So, what is hosted private cloud? Like almost every product in the cloud space, there’s a lot of ambiguity about what you’ll be getting if you sign on to use a hosted private cloud solution. Today, NIST defines private cloud as:
The cloud infrastructure is provisioned for exclusive use by a single organization comprising multiple consumers (e.g., business units). It may be owned, managed, and operated by the organization, a third party, or some combination of them, and it may exist on or off premises.
Hosted private cloud refers to a variation of this where the solution lives off-premises in a hosted environment while still incorporating NIST's IaaS service definition, particularly where “[t]he consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, and deployed applications.” But there’s a great deal of variation in today’s hosted private cloud arena. Usually solutions differ in the following ways:
Sound familiar? Executives across the globe feel peer and competitive pressure to “get to yes” on private cloud. This burden falls on IT to provide a cloud solution — oh, and by the way, we need it by the end of the year. With this clock ticking, it’s hard to think about private cloud strategically. In fact, why not to just cloudwash your virtual environment and buy your team time? Many enterprises (yes, even those presenting at events) have gone down this road. And some vendors will suggest this as a short-term fix. DON’T DO IT.
You’re cutting yourself short on what you could achieve with this environment while losing credibility with the business and your peers. Sound overdramatic? The consumerization of IT is forcing IT to connect with the business or risk circumvention. For many, the existing relationship isn't great. And each future interaction could either improve or worsen that relationship. Promising the business a cloud delivered within your own data center, and then failing to provide basic functionality of a cloud will just make future initiatives and interactions even harder. In the meantime, the business will continue to circumvent your department. If you're going to invest the resources/time to build this environment and rope in rogue cloud users — make sure you get to cloud.
Over the last couple of years, IBM, despite having a rich internal technology ecosystem and a number of competitive blade and CI offerings, has not had a comprehensive integrated offering to challenge HP’s CloudSystem Matrix and Cisco’s UCS. This past week IBM effectively silenced its critics and jumped to the head of the CI queue with the announcement of two products, PureFlex and PureApplication, the results of a massive multi-year engineering investment in blade hardware, systems management, networking, and storage integration. Based on a new modular blade architecture and new management architecture, the two products are really more of a continuum of a product defined by the level of software rather than two separate technology offerings.
PureFlex is the base product, consisting of the new hardware (which despite having the same number of blades as the existing HS blade products, is in fact a totally new piece of hardware), which integrates both BNT-based networking as well as a new object-based management architecture which can manage up to four chassis and provide a powerful setoff optimization, installation, and self-diagnostic functions for the hardware and software stack up to and including the OS images and VMs. In addition IBM appears to have integrated the complete suite of Open Fabric Manager and Virtual Fabric for remapping MAC/WWN UIDs and managing VM networking connections, and storage integration via the embedded V7000 storage unit, which serves as both a storage pool and an aggregation point for virtualizing external storage. The laundry list of features and functions is too long to itemize here, but PureFlex, especially with its hypervisor-neutrality and IBM’s Cloud FastStart option, is a complete platform for an enterprise private cloud or a horizontal VM compute farm, however you choose to label a shared VM utility.
Well, maybe everybody is saying “cloud” these days, but my first impression of Microsoft Windows Server 8 (not the final name) is that Microsoft has been listening very closely to what customers want from an OS that can support both public and private enterprise cloud implementations. And most importantly, the things that they have built into WS8 for “clouds” also look like they make life easier for plain old enterprise IT.
Microsoft appears to have focused its efforts on several key themes, all of which benefit legacy IT architectures as well as emerging clouds:
Management, migration and recovery of VMs in a multi-system domain – Major improvements in Hyper-V and management capabilities mean that I&O groups can easily build multi-system clusters of WS8 servers, and easily migrate VMs across system boundaries. Muplitle systems can be clustered with Fibre Channel, making it easier to implement high-performance clusters.
Multi-tenancy – A host of features, primarily around management and role-based delegation that make it easier and more secure to implement multi-tenant VM clouds.
Recovery and resiliency – Microsoft claims that they can failover VMs from one machine to another in 25 seconds, a very impressive number indeed. While vendor performance claims are always like EPA mileage – you are guaranteed never to exceed this number – this is an impressive claim and a major capability, with major implications for HA architecture in any data center.
