Cloud Computing
Cloud computing is a general term for anything that involves delivering hosted servicesover 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). Cloud Computing includes “pay-for-what-you-use” model andresembles the way electricity, fuel and water are consumed, it's sometimes referred to
as utility computing.
A cloud service is (1) sold on demand, typically by the minute or the hour (2) it is elastic,
a user can have as much or as little of a service as they want at any given time, and (3)
the service is fully managed by the provider. Significant innovations in virtualization and
distributed computing, as well as improved access to high-speed Internet and a weakeconomy, have accelerated interest in cloud computing. Learn more here.
A cloud can be private or public. A public cloud sells services to anyone on the Internet.
(Currently, Amazon Web Services is the largest public cloud provider.) A private cloud is
a proprietary network or a data center that supplies hosted services to a limited numberof people. When a service provider uses public cloud resources to create their privatecloud, the result is called a virtual private cloud. Private or public, the goal of cloudcomputing is to provide easy, scalable access to computing resources and IT services.
Infrastructure-as-a-Service like Amazon Web Services provides virtual server instances
with unique IP addresses and blocks of storage on demand. Customers use the
provider's application program interface (API) to start, stop, access and configure theirvirtual servers and storage. In the enterprise, cloud computing allows a company to payfor only as much capacity as is needed, and bring more online as soon as required.
Because this pay-for-what-you-use model resembles the way electricity, fuel and water
are consumed, it's sometimes referred to as utility computing.
Platform-as-a-service in the cloud is defined as a set of software and productdevelopment tools hosted on the provider's infrastructure. Developers createapplications on the provider's platform over the Internet. PaaS providers may use APIs,
website portals or gateway software installed on the customer's computer. Force.com,
(an outgrowth of Salesforce.com) and GoogleApps are examples of PaaS. In thesoftware-as-a-service cloud model, the vendor supplies the hardware infrastructure, the
software product and interacts with the user through a front-end portal. SaaS is a verybroad market. Services can be anything from Web-based email to inventory control and
database processing. Because the service provider hosts both the application and thedata, the end user is free to use the service from anywhere.
