Cloud Computing basics

Cloud computing


Most of the IT people knows how long it takes for provisioning servers (Physical, VM), databases, making networking connection across servers/computers and many more activities. Cloud computing made all things are easy to use. Most of the organizations use different software to be provisioning of servers, databases etc., for that they must buy some physical servers and additionally they must pay if they are going to maintain in some data centre. There are so many factors it takes more manual works, hardware setup, power/network connections etc.,


Use cases like healthcare companies are using the cloud to develop more personalized treatments for patients. Financial services companies are using the cloud to power real-time fraud detection and prevention. And video game makers are using the cloud to deliver online games to millions of players around the world.


Cloud computing playing key role to cover some of these aspects for Organization by maintaining Infrastructure for their customers. Customers need to worry much about maintaining/renting/paying for data centre. Cloud computing is the on-demand delivery of IT resources over the Internet with pay-as-you-go pricing. Instead of purchasing, owning, and maintaining physical data centres and servers, you can access technology services such as compute, storage, and databases on-demand through a cloud provider like Amazon Web Services (AWS).

Cloud computing benefits

  • On-Demand self-service – Provision server anytime

  • Broad network access – Access your resources anywhere

  • Resource pooling – No limits on resource provisioning

  • Go-global in minutes (Worldwide deployments in mins)

  • Measured service – Pay only for what you use (Like Metered billing)

  • Cost Savings

Also, let me give an example to understand better. Let’s explain with Pizza.

  • On-Prem: You need to prepare all the ingredients to make pizza by your own cooking Made at home
  • IaaS: Go to supermarket and buy some frozen pizza and only manage cooking (make it hot and customize if you need anything Take and Back
  • PaaS: Take your mobile and just order your favourite pizza (No ingredients to buy and no cooking) Pizza Delivered
  • SaaS: Just visit any Pizza shop near to your home and have pizza Dined Out


I hope this analogy made you clear understanding about cloud computing service models.
