What is Cloud Computing?

Cloud computing is virtual allocation of computer, server, software and system. It can be used on pay as you go and as needed. Some of its features are:

  • No software or hardware required
  • Access anywhere over Internet
  • Elastic – scale up and down in capacity and functionalities.

Cloud Services are divided into 3 main categories:

Software as a Service (SaaS)
Provides software that you can use without having to install it, manage it, or buy hardware for it. These software range from your email services (Such as Google Apps, Microsoft Office 365 etc.) to document sharing and collaboration (such as Google Docs, Microsoft Office365 SharePoint, Box.net etc.) to Customer Relationship Managers (CRMs such as Salesforce.com, Zoho CRM, vtiger CRM etc.).

These are perfect solutions for Small and Medium size businesses who would like to concentrate on your business but still get the best software and applications for their business with minimum costs.

Infrastructure as a Service (IaaS)
Provides as much virtual server and storage space as you need for your various requirements for example, Web Servers, ecommerce Platforms, Email Servers, Shared Drive Servers, VPN Servers. The optional pay as you go model ensures that you only pay for the resources used by you.

For example, you may want to scale up your ecommerce web server when the demand increases during the Christmas and/or holiday period and scale them back when the users on the website go down. With a cloud server scalability is very easy and quick with almost no downtime to your servers.

Some examples are Amazon Elastic Compute Cloud or Microsoft Azure platform.

Platform as a Service (PaaS)
Provides a set of software and product development tools to build applications on top of the compute infrastructure. This is more focussed towards application and software development companies who would like to roll out their services on the internet with no investment in infrastructure.

For example, Google App Engine, Oracle/AWS, AppFog.com are some such examples.

For next week we are going to cover the benefits of Cloud Computing in further details but here is a preview:
