  • Hyper-V Cloud Hosting solution

    Hyper-V Cloud Computing Solution :


    Windows Server 2008 shipped with several server roles that provide application services such as Active Directory, web services, thin client Terminal Services, video streaming media services, server virtualization services, and many others.

    Microsoft claims that half of its infrastructure is currently virtualized (via Hyper-V presumably), so clearly Microsoft feels that it is ready for production use.

    Microsoft’s cloud solution is based on delivering services to the user through a flexible, easily managed infrastructure. There are two infrastructure models that Microsoft customers can use to implement cloud services : private cloud and public cloud. Customers can choose between these infrastructure models based on their application delivery needs, or they can combine the models to provide a flexible infrastructure of computing resources able to scale to changing service requirements.

    Organizations that want to take advantage of a flexible, dynamic private cloud infrastructure can use Hyper-V™ and System Center to create cloud services within their datacenter. Alternatively, they can also lease VM-based cloud services.

    The comprehensive management offered by System Center monitors hardware, operating systems, virtual machines, and both physically-installed and VM-based applications. This allows System Center to monitor and manage the entire infrastructure, providing a holistic picture of datacenter operations that includes the causal relationships between system components. This eases troubleshooting and facilitates greater efficiency and availability in datacenter operations.

    Microsoft’s cloud computing solutions include:
    * Virtualization and automation.
    * Interchangeable resources such as servers, storage and network.
    * Management of these resources as a single fabric.
    * Elastic scale up or down capability to respond to business demands.
    * Applications and development tools that can truly scale out.
    * Focus on the service delivered to the business.

    Customers can use Microsoft System Center to manage both public and private Microsoft cloud implementations. System Center’s comprehensive management capabilities enable it to monitor and manage the entire IT infrastructure stack from traditional physical servers, virtualized servers, virtual machines, running workloads and all the way up to service-based cloud components. Microsoft System Center works closely with Microsoft’s cloud solutions to help customers create and manage a flexible, reliable computing environment that allows internal customers to easily consume infrastructure, software, and platform services.

    Hyper-V R2 is a long-awaited technology that has been anticipated to help Microsoft leap past rival virtual server technologies such as VMware and XenServer. Although Microsoft has had a virtual server technology for a few years, the features and capabilities have always lagged behind its competitors. Windows Server 2008 R2 was written to provide enhanced virtualization technologies through a rewrite of the Windows kernel itself to support virtual server capabilities equal to, if not better than, other options on the market.

    As customers continue to use server virtualization to cut cost and increase datacenter efficiency, they can leverage the benefits of cloud computing to realize additional gains in efficiency and uptime. Microsoft’s cloud computing solution combines simplicity and flexibility to offer substantial value and choice to customers. In contrast to VMware’s cloud solution, the Microsoft solution provides management and monitoring that extends from the hardware to the applications.

    You can use the various flavors of Windows as guests, depending on licensing terms :

    - Windows Server 2000 Server and Advanced Server with SP4 (uniprocessor)
    - Windows XP SP3 32 bit (uniprocessor)
    - Windows Vista SP1 32 & 64 bit (uniprocessor)
    - Windows 7 client 32 & 64 bit (uniprocessor)
    - Windows 7 client 32 & 64 bit (multiprocessor, two virtual processors)
    - Windows Server 2003 SP2 32 & 64 bit (uniprocessor)
    - Windows Server 2003 SP2 32 & 64 bit (multiprocessor, two virtual processors)
    - Windows Server 2003 R2 SP2 32 & 64 bit (uniprocessor)
    - Windows Server 2003 R2 SP2 32 & 64 bit (multiprocessor, two virtual processors)
    - Windows Server 2008 32 & 64 bit (uniprocessor)
    - Windows Server 2008 32 & 64 bit (multiprocessor, four virtual processors)
    - Windows Server 2008 R2 32 & 64 bit (uniprocessor)
    - Windows Server 2008 R2 32 & 64 bit (multiprocessor, four virtual processors)
    - SUSE Linux Enterprise Server 10 (x86/x64) (uniprocessor, no integration components)

    Note that Red Hat and Microsoft have announced a joint support agreement. RHEL will be supported as a guest within Hyper-V and Windows Server 2008 will be supported within RHEL guest VMs.

    Single processor VMs of SUSE Linux Enterprise Server 10 without integration components are currently the only recommended Linux distribution during RC.

    Comparison of Windows 2008 Hyper-V R2 with VMware vSphere :

    1) R2 has Live Migration comparable to vMotion.
    2) R2 has Storage Migration comparable to Storage vMotion. (with VVM 2008 R2)
    3) R2 has clustering comparable to HA
    4) With SCOM, R2 has PRO comparable to DRS. (SCOM not free, but you may have this already or need it to manage your Windows infrastructure regardless of hypervisor used).
    5) R2 has support for the same storage normally used as ESX (iSCSI, FC)
    6) R2 has support for cluster shared volumes which is comparable to VMFS.
    7) R2 will come on bootable USB, just like ESXi.
    8 ) R2 has comparable security (attack-wise) as ESX, as Hyper-V is the only role activated.
    9) R2 is easier to manage and supervise with SCOM, as it can check the whole stack from hardware via hypervisor into the VM and even its applications (SQL, Exchange etc).
    10) R2 is free or nearly free, whereas vSphere (using five hosts with four sockets each) will cost approximately $2875/processor (that is Enterprise, not enterprise plus) in licenses with more or less the same feature set. The license cost for the VMs will be there regardless of hypervisor.
    11) The Microsoft VDI solution may counter View 3 as is supports 64-bit guests and Windows 7 right out of box, and also built-in to AD management.
    12) Performance will probably be comparable between the two.
    13) Features like FT and host profiles are quite nice, but hardly a differentiator in real life for a medium-sized business. Also, to get this you must pay $3495 per proc.
    14) With the Enterprise edition you can use 256 Gb RAM. You can use 1 TB RAM with R2.
    15) With VMFS, you are limited to 2 TB partitions and need to use extents to get bigger. With R2, there is no practical limit in size.
    16) Both products have thin provisioning to save SAN space.

    If you are looking for Windows Cloud server and want to save windows license cost then go for Hyper-V Cloud solution
