Virtualization is one piece of the story, but taking it one step further, the key to really increasing flexibility on premises is by creating a private cloud in your datacenter. The power of software transforms diverse platforms into a single entity that you can manage as a whole. Pooling resources creates an infrastructure fabric that is both more resilient and also more elastic, because you can move resources easily to accommodate spikes in demand. And with the right technologies, the private cloud becomes an enterprise grade platform that will give you the uptime and the performance at the low TCO that the business requires.
Many IT leaders today are asking, ???????why private cloud???????? One of the things that the industry is learning from cloud computing is how pooled resources can increase datacenter efficiency. It????????s easier to guarantee uptime, easier to manage holistically, and easier to keep costs down through more efficient use of resources. However, use of the public cloud isn????????t for every business all of the time. There are workloads and data that you still need to keep on-premises. And that????????s where the private cloud comes in.
Microsoft System Center 2012 and Windows Server 2012 offer customers the best options available for creating an infrastructure fabric in the datacenter. Microsoft????????s virtualization platform is designed for the most demanding workloads. The integrated management toolset of Microsoft System Center 2012 covers the full range of management needs, from physical to virtual, from the virtual machine to the application itself. System Center 2012 also allows you to manage across heterogeneous infrastructure, so that you have a single view of the datacenter and the cloud????????including management of Linux workloads and multi-hypervisor management.
Once you have the pooled resources or private cloud in place in your own datacenter, you can take the next step and expand outside the datacenter????????connecting to Windows Azure or a Service Provider cloud. This gives you a nearly endless set of resources to draw on as needed. The main question you need to consider is where and when to leverage public cloud resources. Think about workload mobility, workloads with unpredictable demand, or just look at where you could reduce costs with cloud resources.
Windows Azure offers an ideal platform to extend your own datacenter capacity. You can easily access Azure resources when it makes the most sense for your business: new applications or websites that require global scale in a snap, infrastructure that needs to scale at a moment????????s notice to meet the most demanding business requirements, cloud economics that let you reduce your on premises costs for storage, back-up and recovery. And you get consistency across clouds so that when you????????re taking advantage of the new hybrid model, you????????re not adding a lot of complexity to the process.
In a recent IDC Cloud Survey, 60% of customers polled said that the cloud solution provider (CSP) they work with needs to be somebody they have a trusted relationship with in order to make them their vendor of choice. In addition, ~65% also said that the CSP should be able to offer to move their cloud solution back on-premises if needed. Windows Azure Infrastructure Services using the same virtual machine format as Windows Server. Both are running WS 2012 giving you the ultimately flexibility to move your workloads where you need them. And unlike other providers, Microsoft charges you only for what you use, by the minute not the hour, and they financially back all of their SLAs.
Microsoft is using its technology internally as well. Inside of the Server and Tools business unit, where we build SQL and Windows Server and System Center, we have a shared private cloud for all of our testing and all of our qualification. The private cloud has 4,000 servers, and on any given day there are 40,000-45,000 VMs running on that cloud. That????????s mission critical for the engineering teams, and it????????s all based upon the same technology that you use in your datacenters.
