Today everyone who logs on to Facebook or similar social networking sites, uses Cloud Computing. What is it and what does it mean to a normal user? Well in simple terms it is a cluster of server farms where all your data is mirrored. So whenever a request goes out from your browser to fetch an image on Facebook, it is routed through to one of these servers. These servers could are spread across the globe or within a single country itself.

From business point of view cloud computing has many benefits. That’s why many companies are already switching over to cloud computing. They have started hosting their web applications in cloud. Some of these benefits are:

  • Whether it’s CPU power or storage, pay only for what you use.
  • Easy access to more storage as required. This helps in scalability.
  • Auto Updates for software and hardware relieves IT team from future upgrade worries.
  • High availability of your data in case of any disaster.

There are many companies that offer cloud computing services. Some of these are Amazon, Google, Salesforce, Rackspace, HPDell and Microsoft.
