Companies are constantly trying to get an edge. This is especially true in IT, where every dollar, every person-hour counts. We’ve seen it basically since IT was invented. From file cabinets that were color-coded and slightly more efficient than their gray-only predecessors to moving critical operations to the cloud, and everything in between, IT has always looked to save and become more efficient, in small increments and large ones.
With that in mind, we pose the question that became the title of this post: is it time to virtualize your critical workflows? Honestly, we wouldn’t be asking if the answer weren’t “yes.” By now, you probably know many of the benefits that virtualization can bring to your organization, including improved power consumption and utilization of resources, higher server consolidation ratios, greater workload mobility, and much easier system management.
This blog post isn’t just for those considering virtualization for the first time, however. Those of you who have already gone down the virtualization road know there are a few industry trends pushing those consolidation ratios even higher, including the desire to further improve power consumption and resource usage, multicore technology and dynamic resource allocation.
We all know, however, that these benefits don’t come without new requirements and potential risks. As more and more business-critical workloads are deployed in virtualized machines, the failure of a single physical server can interrupt a lot of services. This risk is simply unacceptable for a lot of organizations. Working with KeyInfo partner VMware, we can help take this type of risk out of virtualization and help make it a reality.
Fault tolerance to reduce risk
VMware Fault Tolerance (FT) delivers hardware-style fault tolerance into virtual machines. The encapsulation properties of virtualization are well known by now. VMware FT uses these properties to build high availability directly into the ESX hypervisor – so it doesn’t need custom software or hardware. With this model, guest operating systems and apps aren’t even aware of the protections delivered by ESX and the underlying architecture, and they don’t need reconfiguration or modifications of any kind.
VMware FT uses VMware vLockstep to create a secondary virtual machine running in lockstep with the primary one. This secondary machine lives on a different host while executing an identical sequence of virtual instructions as the primary. Because of this, if a failure occurs, the secondary machine can immediately take over with no service interruptions or data loss.
Take a look at KeyInfo’s VMware partner page to learn more details, but if you’ve been putting off virtualization – or if you’re considering expanding your use – VMware FT can eliminate potential issues and put your mind at ease.
