Three Ways for Corporations to Cloud Compute

Cloud Computing means running and processing information through the Internet. It automatically breaks down the complex computing process into various sub processes. Then through parallel calculation by many servers, the resulting data is sent back to the Cloud client. Cloud clients do not require any professional knowledge on Cloud computing and related infrastructure. Cloud computing includes three levels of service: IaaS, PaaS and SaaS.

IaaS (infrastructure as a Service) means providing the necessary infrastructure for computing. Infrastructure include servers, network equipment, RAM, disk, CPU and data center.

PaaS (Platform as a Service) basically provides a platform allowing developers flexibility to customize web applications. Cloud clients or users could then have direct access through the Internet without downloading or installing.

SaaS (Software as a Service) is a software application model. In this model, software is controlled by the service provider then distributed to users through the Internet. No installation or upgrades are required on the client end. Examples include Google Docs, Dropbox and EverNote.

To sum up, there are basically two kinds of Cloud Computing:

1.     Cloud Computing Services: Some Internet services use one browser and process/ saves data through the Internet. This kind of Cloud Computing is an extension of SaaS and therefore does not require users to worry about expanding available space.

2.     Cloud Computing Technologies: This kind of Cloud Computing uses the “cloud” concept and pulls multiple computers together to process, document and backup one another.
