Looking through a Cloud.

Cloud as well as the Virtualization always helped IT managers in reducing TCO considerably and also in providing an ideal solution to optimize their IT infrastructure utilization.

How to embrace this Cloud is a real challenge for every new IT managers and for the companies, plans to go for implementing this comparatively new but proven technology.

Vmware, Citrix, Hyper-V are the key backstage players in provisioning cloud and virtulization technologies to all enterprise class and Datacenters deployments. While Vmware uses their proprietary hypervisor called ESX whereas Citrix based on the most popular Xen hypervisor and Microsoft uses their Hyper-V now.

The underlying technology behind every Cloud computing and Virtulizations are the same Hypervisors as they are installed on bare metal hardwares, makes the virtualization possible. Management of whole the computing power, accomplished using it. All the resources like processors, memory, storage, networking capabilities etc, attached can be sliced as per the difference in each requirements and even this can be changed later, even if it is Live and running ..!

Multiple operating systems can be easily installed in any of these new Virtual Hardwares, also all the popular distros of both Linux and Windows can have on a same physical server.

Most of our studies indicate that less than 15% IT resources of installed capacity is only being utilized in organizations, where a very huge amount been spent over IT infrastructure setups and its management. Many of their servers are under utilized, since they are running mainly for just one or two applications and probably only one application may require large resources while others use very less or minimal.

Virtualization helps in pooling of hardware resources and allocating them only while its demand occurs. This prevents resource idling and provides intelligent resource allocation for maximum utilization.

Each OS installations on Virtualized instances are described as Virtual Machines or just VM. In additional to Hypervisors, there will be other add-on technologies, which enable the other fundamental features,

High Availability:

Availability of installed Applications are always ensured by early detection of any failures and its automated corrective and preventive mechanisms.

VM Migrations

During a hardware failure of VM, handled by quick and automated migration process towards a healthy physical hardware connected to the system to avoid downtime.

Central management

This feature helps management quick & hassle free. Makes easy to manage all the hosts, networks, load balancers, storage and clustering devices assosiated with the cloud environment, from a single point.

Resource Pooling

Aggregating and consolidation of hardware resources CPU, RAM, Storage, networking & other capabilities, into a pool and this can be done even on a live & running deployment

Load Balancing

Distributed Resource Scheduler (DRS) helps to properly allocate computing resources in the virtual environment to ensure the best utilization of all resources.

Storage management

Leverage your existing Storage Solutions and its easier management. iscsi, SAN, NFS etc are all well supported.

Networking

Virtual networking simulates real networking and the advanced features of VLAN's provides additional security for your sensitive data & information perfectly.

These Cloud technologies all together with a proper architectural design, provides ideal & complete solution for datacentres and Enterprises. Making them to provide an on demand, scalable mission-critical application than can run smoothly on the consolidated hardware resource.

Virtualization helps to eliminate the downtime due to a hardware failures. If the hardware which is running VM lands in trouble it will be possible to migrate your VM to another physical server with zero downtime. Replace the hardware install Hypervisor and connect to the cloud network, cloud manager automatically detects the new hardware and add its resources to the resource pool.
