  • The Server Virtualization Landscape, Circa 2007
    ghaff@ illuminata.com Copyright © 2007 Illuminata, Inc. single user license Gordon R Haff Illuminata, Inc. TM The Server Virtualization Bazaar, Circa 2007 Inspired by both industry hype and legitimate customer excitement, many Research Note companies seem to have taken to using the “virtualization” moniker more as the hip phrase of the moment than as something that’s supposed to convey actual meaning. Think of it as “eCommerce” or “Internet-enabled” for the Noughts. The din is loud. It doesn’t help matters that virtualization, in the broad sense of “remapping physical resources to more useful logical ones,” spans a huge swath of Gordon Haff technologies—including some that are so baked-in that most people don’t even 27 July 2007 think of them as virtualization any longer. Personally licensed to Gordon R Haff of Illuminata, Inc. for your personal education and individual work functions. Providing its contents to external parties, including by quotation, violates our copyright and is expressly forbidden. However, one particular group of approaches is capturing an outsized share of the limelight today. That would, of course, be what’s commonly referred to as “server virtualization.” Although server virtualization is in the minds of many inextricably tied to the name of one company—VMware—there are many companies in this space. Their offerings include not only products that let multiple virtual machines (VMs) coexist on a single physical server, but also related approaches such as operating system (OS) virtualization or containers. In the pages that follow, I offer a guide to today’s server virtualization bazaar— which at first glance can perhaps seem just a dreadfully confusing jumble.

Virtualization is one of the key enablers of the cloud infrastructure. Availability of the virtual machines along with the availability of the hosted software components are the fundamental ingredients for achieving highly available services in the cloud. There are some availability solutions developed by virtualization vendors like VMware HA and VMware FT. At the same time the SAForum specifications and OpenSAF as a compliant implementation offer a standard based open solution for service high availability.

Instead, each OS running on a physical consumption, better management through central server becomes converted to a distinct OS running inside environment control, more availability, reduced project a virtual machine.

  • A Comparison of Powervm and X86-Based Virtualization Performance
    A Comparison of PowerVM and x86-Based Virtualization Performance October 20, 2009 Elisabeth Stahl, Mala Anand IBM Systems and Technology Group IBM PowerVM Virtualization Virtualization technologies allow IT organizations to consolidate workloads running on multiple operating systems and software stacks and allocate platform resources dynamically to meet specific business and application requirements. Leadership virtualization has become the key technology to efficiently deploy servers in enterprise data centers to drive down costs and become the foundation for server pools and cloud computing technology. Therefore, the performance of this foundation technology is critical for the success of server pools and cloud computing. Virtualization may be employed to: • Consolidate multiple environments, including underutilized servers and systems with varied and dynamic resource requirements • Grow and shrink resources dynamically, derive energy efficiency, save space, and optimize resource utilization • Deploy new workloads through provisioning virtual machines or new systems rapidly to meet changing business demands • Develop and test applications in secure, independent domains while production can be isolated to its own domain on the same system • Transfer live workloads to support server migrations, balancing system load, or to avoid planned downtime • Control server sprawl and thereby reduce system management costs The latest advances in IBM® PowerVM™ offer broader platform support, greater scalability, higher efficiency in resource utilization, and more flexibility and robust heterogeneous server management than ever before. This paper will discuss the advantages of virtualization, highlight IBM PowerVM, and analyze the performance of virtualization technologies using industry-standard benchmarks. PowerVM With IBM Power™ Systems and IBM PowerVM virtualization technologies, an organization can consolidate applications and servers by using partitioning and virtualized system resources to provide a more flexible, dynamic IT infrastructure.

Cloud Virtualization Technology 7.1 Introduction ● Virtualization represents the logical view of data representation- the power to compute in virtualized environments. ● It is a technique that has been used in large mainframe computer for 30+ years. It is used to manage a group of computers together- instead of managing resources separately. www.getmyuni.com 7. Cloud Virtualization Technology 7.2 Virtualization Defined Virtualization is an abstraction layer (hypervisor) that decouples the physical hardware from the operating system to deliver greater IT resources utilization and flexibility Virtualization can bring the following benefits ● save money ● increased control ● simplify disaster recovery ● business readiness assessment www.getmyuni.com 7. Cloud Virtualization Technology 7.2.1 Why Virtualization? Here are some reasons for going for virtualization ● lower cost of infrastructure ● Reducing the cost of adding to that infrastructure ● Gathering information across IT set up for increased utilization and collaboration ● Deliver on SLA response time during spikes in production ● Building heterogeneous infrastructure that are responsive www.getmyuni.com 7. Cloud Virtualization Vechnology 7.2.2 Infrastructure Virtualization Evolution ● The objective of virtualization is to reduce complexity in building and managing IT infrastructure. ● Virtualization has been in operation in mainframe computers ● different machines can run different operating systems and multiple applications on the same physical computer.
