Cloud computing is the on-demand delivery of computing resources on the internet to store, manage, and process data, rather than storing in a local server or a personal computer.

Organizations before cloud computing

Before cloud computing was introduced every organization would have its servers hosted in their location. This system has got many disadvantages. Maintaining physical space is not easy, they usually have high real estate costs, they need cooling systems, their electricity costs are huge. Along with all these, companies also need to maintain a backup data center in a different place as a safety measure in case any disaster occurs. So, due to the above disadvantages of server-based computing, companies started using cloud-based computing.

Cloud providers

Some of the popular cloud providers are Microsoft Azure, Amazon web services, IBM Cloud, Google cloud platform, etc.

Benefits of cloud computing

  • Cost-effective​

Cloud computing is cost-effective because all the requirements are taken care of by the cloud. There is no hardware or software cost.

  • Scalable​

Cloud computing is scalable. It can scale up when the requirement is huge and scale down when the requirement is low.

  • Elastic ​

Cloud computing is elastic. It can adapt to workload changes by provisioning and de-provisioning resources in an autonomic manner.

  • Always up to date​

There is no need to download or update any software to use the latest version of your cloud. It is automatically updated and makes sure you use the latest version.
