What Is Cloud Computing?
“Cloud Computing” is a sustainable, long-term IT paradigm and the successor to previous mainframe, client/server and network computing eras. Cloud infrastructures have the potential for economic and functional benefits that will drive the transformation from traditional software and hardware into IT subscription services and pay-per-use models.

An enterprise might subscribe to a public cloud or a private cloud. They might move applications to the cloud or build their own cloud. Whatever the strategy, tailored service level agreements, single or multi-tenancy, scalability and security are tailored to meet the needs of the organization.

What drives Cloud adoption?

Private Cloud
If an enterprise needs to be the only subscriber based on security or regulation requirements, a private cloud would meet their needs. Then the decision becomes where the private cloud is to be located, internally or at a cloud-provider? The cloud-provider will give the most flexibility concerning scalability up and down the environment. The enterprise would let the cloud provider provide the entire infrastructure as a service (IaaS) and the enterprise would focus on the applications.

Public Cloud
On the other hand, the enterprise may decide to move to a public cloud where the cloud is shared with other subscribers. Like the private cloud, the public cloud gives the enterprise the flexibility to ramp up quickly when demand is high and scale back just as easily when demand is low. The cloud provider manages all infrastructure and equipment while the enterprise pays only for the resources required. The cloud is shared with other subscribers but the applications, web services and data of an enterprise are isolated and secure.

Benefits of the Cloud
There are many types of clouds such as storage clouds, database clouds, testing clouds and platform clouds. In addition, hybrid clouds offer a mix of external and internal (i.e., private) clouds with the capability to move between the two. Regardless of the type of cloud, the benefits include:

 

Cost Capital expenditures converted to operational expenditure
Agility Ability to rapidly and inexpensively re-provision technological infrastructure
Device and location independence Web browser access regardless of location or device
Multi-tenancy Enables sharing of resources and costs across a large pool of users
Reliability Well-designed cloud computing is suitable for business continuity and disaster recovery
Scalability On-Demand Resources
Maintenance Applications are easier to maintain, everyone gets the updates at the same time

Steps to the Cloud
Steps for moving to the cloud involve virtualizing application-based silos of servers, storage and network and moving to the cloud infrastructure of your choice, at the location of your choice. Some organizations venture further into the cloud computing paradigm and provision their own internal cloud to customers. But, how do you choose the right application to start with? How do you build in scalability? What security do you add and where? ITgility can help you answer these important questions with our three-step process of Define, Identify and Execute.
