Evolution and Trends of Virtualization Technology Welcome to a faster more efficient IT infrastructure Virtualization software has rapidly transformed the IT landscape and has changed the way people compute. Our servers, storage devices and networks have been transformed and 'virtualized' from physical and tangible artifacts to mere 'files' sitting atop a thin layer of software called a hypervisor. Decoupled from the physical world, these compute resources and virtual machines can be dynamically allocated with just a few clicks and keyboard strokes. Virtual Machine means no hardware The operating system can't tell the difference between a virtual machine (vm) and a physical machine, nor can applications or other computers on a network. Virtual machines think and act like a "real" computer, but since VMs are composed entirely of software and contain no hardware components they offer a number of distinct advantages over physical hardware. VMs can be copied, replicated, migrated and even scripted; they are after all merely files sitting on a layer of software. A variety of advantages Virtualization began in 1960 with mainframe computers, to methodically and logically divide the system's resources provided by mainframes between different applications. IBM began this work in 1964, but the full adaptation of server virtualization wasn't until 1999 when VMware introduced their VMware Virtual Platform to the market. VMware found a way to completely virtualize an IT's hardware infrastructure. The advantages brought on by virtualizing technology are more impactful than ever before. Virtualization has enabled IT to more effectively deal with shrinking IT budgets, scarcity of resources, the need for operational flexibility, energy conservation, and dramatically increased information security. If your organization has already taken the leap into virtualization, what's next on the horizon? Hybrid offers complete control For many organizations, developing a hybrid cloud strategy is the next logical step. Bridging your virtualized data center with the public cloud (aka Hybrid Cloud) combines the advantage of scalability and cost-effectiveness that a public cloud computing environment offers, without exposing critical applications and data to third-party vulnerabilities. Adopting hybrid architecture provides you with complete control over your cloud environment, higher security and privacy control, the ability to react and evaluate outages, man- made issues or natural disasters, and will often provide additional budgetary flexibility. AnewwaveofVM We are likely to see the wide spread adoption over the next couple years of both automated and virtualized networks, security and even virtualized operations. Both virtualization and automation have become a necessity, both for driving down costs and enabling us to operationalize our ability to deliver new services at an ever-increasing pace. But the biggest change might just be a completely new approach. Adopting the new approach Companies like Docker and CoreOS, with their recently announced Rocket container technology are quickly gaining attention and trying to plant a flag both in your data center and in the cloud. In some ways the approach is almost anti-virtualization. The intent is to provide a self-contained platform for building, shipping and running distributed applications. Essentially providing applications or portions of an application packaged in self-contained lightweight containers that run independent of either a physical or virtual platform. n Contact your PCMG Account Executive today to gain access to the highest quality technology, industry leading partners, and exceptional service. 1-800-625-5468 | www.pcmg.com 12 PCMG holds a number of public sector procurement contracts.
