As the business shifts to an IT-as-a-Servicemodel new roles may emerge. In the virtualized environment, the role of the VM administrator has evolved (as the tools have evolved), This enables the VM admin to fully manage storage. As these tools continue to evolve, the role of infrastructure manager will be covered by architects who will: design the VDC/Cloud, administrators across the layers, and as things become more automated orchestration and capacity management will grow in importance. Does this mean there are new jobs and old ones are removed? We don’t think that is likely. What we see is a trend to new duties and roles for existing resources. For example, they will spend less time performing the manual tasks, such as change management. As more of the tasks become automated, they will use their time creating templates that have a broader impact and perform automated rolling upgrades.
This chart shows the basic definitions of different types of service models with some example service providers.Co-location -usually means that the provider has a place in the data center dedicated to your company’s equipment. Your company owns and operates all the equipment and is responsible for managing and operating it. The Colo provides “power, pipe (network), and ping (routing)” and of course heating/cooling and physical security. A Colo usually offers to put your equipment in its own caged off area or in a shared caged area providing a second level of security.Managed Service Provider (MSP) –the equipment can still be owned by the customer and the MSP will add services that help with the management of a customers systems such as: update/patch management, security, backups, DR. Or, the MSP can own the systems and manage them up to the application layer and the customer manages the application and the user community that uses the application.Cloud –in a full public Cloud the equipment is owned by the Cloud provider and seems limitless in terms of scale and power. The customer can use resources based on application demand and pays for the resources used.
In this example, a consumerarchive start-up collects “captured” information that is in hardcopy format and stores it in the Cloud, encrypted with tags for search/lookups.They used Amazon Web Services Cloud for development and production—all OPEXcosts with almost no capital expenses. They forecasted that if they grew by double every year for 6 years they would save money by using Cloud services for their application development and production. Location of the resources doesn’t matter –as the dev/test environments are served by federated Clouds. Risk is traded off against cost and convenience.

● Virtualization is the foundation on which cloud infrastructure is built.
● provide secure, isolated sandboxes for running untrusted applications.
● Reliability and Availability,
– A software failure in one VM does not affect other VMs.
– Server consolidation can bring cost reductions from hardware economies of scale,
personnel cost reductions, floor space, and software licenses.
- Typical savings: 29% to 64%.
● Load Balancing,
– The state of a VM is completely encapsulated in the VMM: easy to migrate VMs to other
platforms to improve performance.
