Cloud Computing


Definition

Cloud Computing is the use of Internet computer and software technologies to provide a variety of computer and software services.

Which allow customers to leverage Cloud supplier's hardware, network, software, and storage.

It is a way to increase capacity or add capabilities on the fly without investing in new infrastructure, training new personnel, or licensing new software.

This allows the consumer to focus on their business and not on being an IT supplier.


The Cloud

The Cloud represents the Internet as it is often depicted in computer network diagrams.


Cloud Services

Cloud Services are a well defined set of offerings that are delivered through a Service Catalog.

The customer can pick services from the catalog that fit their specific technology needs.

They can be spun up on demand and exterminated when no longer required.

It can be very much like a cafeteria style offering of services.

The customer can consume the service when needed.

The Cloud Confusion

There is lots of confusion as to what constitutes the Cloud. For instance, many Server Virtualization Companies make the claim that Server Virtualization is Cloud Computing.

Server Virtualization is basically the consolidation of physical servers by the use of Virtualization. The benefit is a reduction of the number of physical servers.

Technically, you do not need Virtualization to implement Cloud Computing.

What you do need is economies of scale in order to make the Cloud a worth while endeavor which is very do able through Server Virtualization.

Otherwise, the Cloud Service would need to be managing a very large physical server environment.

Although, Virtualization is not the same as the Cloud, it is a way to accomplish part of this goal.
