While a lot of people (me included) are excited about the technical speeds and feeds of the vSphere 6 launch, there is something much more fundamentally important about this release. Some technical highlights include 64 node clusters, 8000vm’s per cluster, 480 pCPU’s & 12TB RAM & 2048 VM’s per Host, 128 vCPU & 4TB RAM per VM support, SMP FT (up to 4 vCPU FT), enhancements to NIOC, VVOLs, SIOC enhancements etc, and much more. The reason this release is more fundamentally important though is related to the same reason that Amazon with AWS went from nothing to cloud leader. It’s not just about the technology, but what the technology enables, changing the business model, reducing friction, enabling flexibility. What might seem like a relatively small feature on the surface has the potential to change the landscape in hybrid cloud SDDC. If you’d like to know more about this, and all of the goodness coming as part of the launch of vSphere 6, keep reading.
VMware is about to release the latest version of the flagship vSphere product in what I predict will be a defining moment for the Mobile / Cloud Era. For the first time you will be able to live migrate, without any disruption, between private cloud datacenters, to public cloud, and over long distance, a true hybrid cloud and software defined datacenter. You will be able to implement improved quality of service for all applications with additional SLA guarantees, and scale to unprecedented levels. All while reducing management overheads and complexity across the entire ecosystem. With the policies following the virtual machines and virtual applications regardless of where they are physically located.
This release has been baking for a while and for good reason. There is a big commitment to product quality, which was evidenced by the first ever public beta for VMware vSphere. This is a major release, and is well deserving of the 6.0 version number. A lot of hard work has gone into this release by thousands of people. I was able to test a lot of the functionality during the beta and it was great to be able to contribute to the product.
So why do I think this is such a defining moment? The world is changing with the massive explosion of mobile smart phones and the applications that support them. Billions of users are now demanding their applications wherever and whenever they want. So not only are the users mobile, their applications need to be. The applications need to be able to scale massively and on demand, and move to wherever it makes sense.
Previously migrating workloads from a private cloud or private SDDC to a cloud provider and to support a hybrid cloud required the systems being migrated to be shut down. You could migrate templates and power them on and update load balancer records, but that’s not quite the same as being able to dynamically live migrate any workload from your datacenter to a cloud without any downtime or disruption, and across long distances. If you really wanted to deliver cloud workloads and mobile workloads at scale, they had to be written for a particular cloud environment. Then you are stuck in a hotel California, where you can check out, but can never leave. This is the fundamental difference, and the fundamental technical change that is potentially enabled by vSphere 6, which in turn will deliver business and commercial disruption to current models.
The enhancements to VMware vMotion have the potential to change the way organisations run their datacenters, applications and interact with cloud service providers. It is conceivably possible to migrate workloads between different clouds on demand, based on various business rules and policies, provided they are based on vSphere 6.
So where does the comparison to Amazon and AWS come from? The reason I believe AWS became successful it not because of technology, it’s because it changed the economic and business model of consuming infrastructure. It reduced the friction, made everything on demand, and delivered to development and applications teams, in a way that was transparent. With the VMware vMotion enhancements allowing Cross vCenter vMotion and Long Distance vMotion, Cloud Service Providers can provide even less friction, on demand, run anywhere appropriate type of service. Some of the tyrannies of the network and live migration are being demolished. This again can change the way infrastructure is consumed and make it easier for app teams to deliver. But this needs to be blended with a commercial construct that also supports it.
At VMworld in 2014 Bill Fathers, Father of vCloud Air, reported that some 6% of workloads were running in Cloud environments. I believe part of the reason is because of the difficulty in migrating workloads to a Cloud, and between different Clouds, without disruption, and without having to change the underlying apps. With the changes that VMware is starting to deliver from vSphere 6, conceivably this could rapidly change the adoption of VMware compatible Clouds. There is still much to do in terms of the Network, which is still one of the barriers to Cloud, but this will go a long way. Soon you will be scaling workloads on demand to support the billions of mobile users and migrating those workloads to the cloud of choice that makes sense, almost anywhere in the world.
I was recently at the Singapore VMUG User Conference and listening to one of my colleagues, Scott Drummonds, talk about Cloud and locality. Locality is important because there are orders of magnitude computational difference the further the users are from their applications and data. How this relates back to the VMware vSphere 6.0 launch and vMotion Across vCenter and Long Distance is that it will now be possible to migrate workloads on demand closer to where the users are, especially as we start to see Cloud services become more local, and more miniaturised over time.
Final Word
At first glance vMotion Across vCenters and Long Distance vMotion may not seem that revolutionary. When you put this all in the context of the Hybrid Cloud and Software-Defined Datacenter that VMware has been building towards for over 5 years it is easier to see that this actually delivers a fundamental change in the way infrastructure resources can be used. It won’t be long before the live migration of VM’s is happening as depicted in the image above. What new possibilities will this open up for businesses? What impacts will this have on data sovereignty? Your thoughts and comments are appreciated.
