Cloud Computing

Cloud Computing

Have you heard about Cloud Computing? Actualy, I just heard Cloud Computing several week ago. However, I already use Cloud Computing for a long time.

Cloud Computing is a general term for anything that involves the provision of services that hosted over the Internet. These services are broadly divided into three categories: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS). The term cloud computing itself inspired by the symbol of the cloud (hereafter still referred to as “cloud” for its understanding remains on track) are often used to represent the Internet in the flow charts and diagrams.

Cloud Computing has three special characteristics that distinguish it from traditional hosting. The service is sold on request, which is usually per minute or per hour; is flexible – that user is allowed to have any desired service according to the time given, and the service is fully managed by the provider (customer only need a computer and Internet access). Significant innovations in terms of virtualization and distributed computing, including improved access to high-speed Internet and economic improvements, have increased interest in people to cloud computing.

Cloud Computing can be labeled private or public. Public Cloud sell the service to anyone on the Internet. (Currently, Amazon Web Services is the largest provider of public cloud.) Private Cloud is a proprietary network or a data center that supplies services including host to people in limited numbers. If a service provider using the resources of private property cloud, then the result is called a virtual private cloud. Private or public, the goal of cloud computing is to provide easy access, scalable to computing resources and IT services.

Here are some breakdowns of the above understanding of Cloud Computing.

  • SAAS (Software As A Service), a concept which the company service providers (providers) have an application that can be used by multiple clients, with this client does not need to set up a server and software licenses purchase, they simply buy the service from the application, of course this will cut the operating costs of the company.
  • PAAS (Platform As A Service), is a type of cloud computing service that menyedikan form application development environment, an application development environment where developers can run applications on the server provider and submitted to his client over the Internet.
  • IAAS (Infrastructure As A Service), is a provision model in which an organization outsources the equipment used to support operations, including storage, hardware, servers and networking components. The service provider owns the equipment and is responsible for housing, running and maintaining it. The client typically pays on a per-use basis.

That is it my explanation about  Cloud Computing. Hope this Cloud Computing article will be useful for you.
