 Cloud Computing Services

As business enterprises are actively looking for flexible IT infrastructure solutions which support their growth and expansion, in terms of scale, quality, and accountability in operations, hosting their business operations on the cloud seems a viable step ahead.

Cloud computing makes data storage and computing available on demand, enabling better sharing of resources despite geographic challenges. These actions translate into minimizing IT infrastructure costs, improved manageability and less maintenance.

 Clouds can be personal (enterprise clouds), public, or hybrid, with each presenting its own set of functionalities.




Stands for: Software-as-a-Service

 - Network-based access and management of commercially available software

 - Operations managed centrally, allowing customers access to applications via the web

 - Lower initial costs as it is subscription based and has no p-front license fee

Examples: Various Google Apps, GoToMeeting, Dropbox, Salesforce, etc.


Stands for: Infrastructure-as-a-Service

Key Features:

 - IaaS performance is dependent upon the combination of server, storage and networking options, as well as software

 - For hybrid cloud deployment IaaS is the key as it enables inter-operability between private and public clouds

 - Data security is in-built and storage is tiered making accessing data super fast.

Examples: Amazon Web Services (AWS), MS Azure, Cisco Metapod, Google Compute Engine (GCE), etc.


Stands for: Platform-as-a-Service

Key Features:

 - PaaS incorporates a web-based user interface, making operating it quite effortless
