Today's re-org at Microsoft comes amidst mixed success as they straddle the gap between capricious individual consumers and the cash-strapped, risk-averse needs of enterprise IT buyers who find themselves years behind the demands of their own capricious workers, who are also consumers when they go home. Windows 8 shows us that Microsoft has more learning to do about where to place those bets, but we also think their work on server, cloud and hybrid cloud is excellent, and that their longer-term strategy is viable. We see this organizational re-alignment as very positive.
The Server and Tools Business becomes Cloud and Enterprise Engineering Group
Satya Nadella and Scott Guthrie both have done a great job of driving Agile development and continuous delivery into every team in STB and that is resulting in faster moving and more compelling products and services. They deserve a lot of credit for this and so putting even more under them seems a good thing. The key is whether it is the right things.
For perspective: one of Microsoft's greatest strengths is that they give smart people development tools that are extremely easy to use and deceptively powerful. So much so that generations of developers will commit themselves and careers to mastery of Visual Studio, for example. Microsoft democratizes software development by lowering the barriers to entry like no other company. The shift to cloud gives them the chance to do it again, and the improvements in Visual Studio 2013 shown at BUILD in San Francisco are superb and stretch smoothly from the datacenter to the cloud.
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.
Only a few months since I authored Forrester’s "Market Overview: Data Center Infrastructure Management Solutions," significant changes merit some additional commentary.
The major vendor drama of the “season” is the continued evolution of Schneider and Emerson’s DCIM product rollout. Since Schneider’s worldwide analyst conference in Paris last week, we now have pretty good visibility into both major vendors' strategy and products. In a nutshell, we have two very large players, both with large installed bases of data center customers, and both selling a vision of an integrated modular DCIM framework. More importantly it appears that both vendors can deliver on this promise. That is the good news. The bad news is that their offerings are highly overlapped, and for most potential customers the choice will be a difficult one. My working theory is that whoever has the largest footprint of equipment will have an advantage, and that a lot depends on the relative execution of their field marketing and sales organizations as both companies rush to turn 1000s of salespeople and partners loose on the world with these products. This will be a classic market share play, with the smart strategy being to sacrifice margin for market share, since DCIM solutions have a high probability of pulling through services, and usually involve some annuity revenue stream from support and update fees.
Earlier this week at its Discover customer event, HP announced a significant set of improvements to its already successful c-Class BladeSystem product line, which, despite continuing competitive pressure from IBM and the entry of Cisco into the market three years ago, still commands approximately 50% of the blade market. The significant components of this announcement fall into four major functional buckets – improved hardware, simplified and expanded storage features, new interconnects and I/O options, and serviceability enhancements. Among the highlights are:
Direct connection of HP 3PAR storage – One of the major drawbacks for block-mode storage with blades has always been the cost of the SAN to connect it to the blade enclosure. With the ability to connect an HP 3PAR storage array directly to the c-Class enclosure without any SAN components, HP has reduced both the cost and the complexity of storage for a wide class of applications that have storage requirements within the scope of a single storage array.
New blades – With this announcement, HP fills in the gaps in their blade portfolio, announcing a new Intel Xeon EN based BL-420 for entry requirements, an upgrade to the BL-465 to support the latest AMD 16-core Interlagos CPU, and the BL-660, a new single-width Xeon E5 based 4-socket blade. In addition, HP has expanded the capacity of the sidecar storage blade to 1.5 TB, enabling an 8-server and 12 TB + chassis configuration.
Last week it was Dell’s turn to tout its new wares, as it pulled back the curtain on its 12th-eneration servers and associated infrastructure. I’m still digging through all the details, but at first glance it looks like Dell has been listening to a lot of the same customer input as HP, and as a result their messages (and very likely the value delivered) are in many ways similar. Among the highlights of Dell’s messaging are:
Faster provisioning with next-gen agentless intelligent controllers — Dell’s version is iDRAC7, and in conjunction with its LifeCyle Controller firmware, Dell makes many of the same claims as HP, including faster time to provision and maintain new servers, automatic firmware updates, and many fewer administrative steps, resulting in opex savings.
Intelligent storage tiering and aggressive use of flash memory, under the aegis of Dell’s “Fluid Storage” architecture, introduced last year.
A high-profile positioning for its Virtual Network architecture, building on its acquisition of Force10 Networks last year. With HP and now Dell aiming for more of the network budget in the data center, it’s not hard to understand why Cisco was so aggressive in pursuing its piece of the server opportunity — any pretense of civil coexistence in the world of enterprise networks is gone, and the only mutual interest holding the vendors together is their customers’ demand that they continue to play well together.
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.
A project I’m working on for an approximately half-billion dollar company in the health care industry has forced me to revisit Hyper-V versus VMware after a long period of inattention on my part, and it has become apparent that Hyper-V has made significant progress as a viable platform for at least medium enterprises. My key takeaways include:
Hyper-V has come a long way and is now a viable competitor in Microsoft environments up through mid-size enterprise as long as their DR/HA requirements are not too stringent and as long as they are willing to use Microsoft’s Systems Center, Server Management Suite and Performance Resource Optimization as well as other vendor specific pieces of software as part of their management environment.
Hyper-V still has limitations in VM memory size, total physical system memory size and number of cores per VM compared to VMware, and VMware boasts more flexible memory management and I/O options, but these differences are less significant that they were two years ago.
For large enterprises and for complete integrated management, particularly storage, HA, DR and automated workload migration, and for what appears to be close to 100% coverage of workload sizes, VMware is still king of the barnyard. VMware also boasts an incredibly rich partner ecosystem.
For cloud, Microsoft has a plausible story but it is completely wrapped around Azure.
While I have not had the time (or the inclination, if I was being totally honest) to develop a very granular comparison, VMware’s recent changes to its legacy licensing structure (and subsequent changes to the new pricing structure) does look like license cost remains an attraction for Microsoft Hyper-V, especially if the enterprise is using Windows Server Enterprise Edition.
I’ve been getting a number of inquiries recently regarding benchmarking potential savings from consolidating multiple physical servers onto a smaller number of servers using VMs, usually VMware. The variations in the complexity of the existing versus new infrastructures, operating environments, and applications under consideration make it impossible to come up with consistent rules of thumb, and in most cases, also make it very difficult to predict with any accuracy what the final outcome will be absent a very tedious modeling exercise.
However, the major variables that influence the puzzle remain relatively constant, giving us the ability to at least set out a framework to help analyze potential consolidation projects. This list usually includes:
