What is Cloud Computing?

Cloud Computing is a service whereby shared resources are provided to computers  as metered service over a network (typically the internet) . This allows consumers & businessmen to use application without installation & access their personal files at any computer with internet access.

Benefits of Cloud Computing

Agility Improves user’s ability to re-provision technological infrastructure resources
Cost Claimed to be reduced since infrastructure is typically provided by a third party & doesn’t need to be purchased for one time or infrequent intensive computing tasks
Device & location independence Enables users to access systems using a web browser regardless of their location or what they are using eg PC or Mobile .
Multi – tenancy Enables sharing of resources & costs across a large pool of users thus allowing for infrastructure at lower cost & also proper utilisation of system that are often only 10-20% utilised
Security Security is often as good or even better than other traditional systems , in part because providers are able to devote resources to solving issues that many customers cant afford

Service Models

Models of Cloud Computing

Cloud Computing providers offer three fundamental services

Infrastructure as a Service (IaaS) – Most basic cloud service model
– Cloud providers offer computers – raw storage, firewalls , balancers & networks  
Platform as a Service (PaaS) – Cloud provider deliver a computing platform or solution stack typically including operating system , programming language execution environment and web server
– Application developers can develop & run their software solutions on cloud platform without the cost & complexity of buying & managing the underlying hardware & software layers  
Software as a Service (SaaS) – Cloud provider install and operate application software in the cloud & cloud users access the software from cloud clients . This eliminates the need to install & run application on cloud user’s own computer simplifying maintenance & support

Meghraj (Government’s Cloud)

  • To  harness the benefits of cloud technology, Ministry of Electronics and Information Technology (MeitY) has initiated a project named as ‘MeghRaj’ for creating a Government of India cloud (GoI Cloud) computing environment at the national level.
  • The GI Cloud is envisaged to provide the following outcomes:
    • Optional utilisation of ICT infrastructure;
    • Speedy development and deployment of e-Gov applications;
    • Quick replication of successful applications;
    • e-Gov.
    • App Store hosting certified applications.

Other Government Initiatives in Cloud Computing

Digilocker Services – Part of goverment’s Digital India Initiative, to enable Indian citizens to store certain official documents on the cloud.
– It is example of IaaS => Storage (infrastructure) is provided as service
Maharashtra Government Maharashtra became the first state to mandate its departments to shift their data storage onto the cloud unlike currently where government departments have their own data storage facilities.
