In 2014 I wrote about Microsoft and Dell’s joint Cloud Platform System offering, Microsoft’s initial foray into an “Azure-Like” experience in the enterprise data center. While not a complete or totally transparent Azure experience, it was a definite stake in the ground around Microsoft’s intentions to provide enterprise Azure with hybrid on-premise and public cloud (Azure) interoperability.
I got it wrong about other partners – as far as I know, Dell is the only hardware partner to offer Microsoft CPS – but it looks like my idiot-proof guess that CPS was a stepping stone toward a true on premise Azure was correct, with Microsoft today announcing its technology preview of Azure Stack, the first iteration of a true enterprise Azure offering with hybrid on-prem and public cloud interoperability.
Azure Stack is in some ways a parallel offering to the existing Windows Server/Systems Center and Azure Pack offering, and I believe it represents Microsoft’s long-term vision for enterprise IT, although Microsoft will do nothing to compromise the millions of legacy environments who want to incremental enhance their Windows environment. But for those looking to embrace a more complete cloud experience, Azure Stack is just what the doctor ordered – an Azure environment that can run in the enterprise that has seamless access to the immense Azure public cloud environment.
On the partner front, this time Microsoft will be introducing this as a pure software that can run on one or more standard x86 servers, no special integration required, although I’m sure there will be many bundled offerings of Azure Stack and integration services from partners.
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.
