What is Cloud Computing?

Delivery of Computing Services like software, storage, servers, etc. over the internet on demand is known as Cloud Computing.

Why Cloud Computing?

Cloud Computing provides the following features, which makes this technology the basic necessity of current times
1.   Speed: With just a few clicks, it gives businesses a lot of flexibility and helps in capacity planning.
2.   Cost: It eliminates the need to buy hardware, which eventually reduces the cost of buying hardware, setting it up and maintaining it.
3.   Productivity: It eliminates the scope of hardware setups, software patching & other time-consuming IT management processes so that the time saved can be used in a more productive manner.
4.   Reliability: It makes disaster recovery, backing up data a lot easier and less expensive as same data is stored at multiple sites.
5.   Performance: This offers multiple benefits over a single datacenter, including reduced network latency for applications and greater economies of scale.
6.   Global Scale: It provides computing services on demand and on the right geographic location.

Applications or Uses of Cloud Computing

·       In creating new apps and services.
·       To store backs up and recovers data.
·       In Hosting websites & blogs.
·       To stream Audio & Video.
·       To deliver software on demand.
·       To analyze data for patterns & make predictions.

Types of Cloud Deployments

1.   Public Cloud: These are owned and operated by third-party providers. We can use these services through web browsers. For example, Microsoft Azure.
2.   Private Cloud: It is owned by a single organization. Services and infrastructure of this cloud are maintained on the private network.
3.   Hybrid Cloud: These are combinations of the above two deployments. They provide greater flexibility and more deployment options to the businesses.

Types of Cloud Computing

o  Infrastructure-as-a-service (Iaas)

This includes providing services like servers, Virtual machines etc. as demanded by the customers.

o  Platform-as-a-service (Paas)

This provides services which supply an on-demand environment for developing, testing, delivering & managing software applications.

o  Software-as-a-service (Saas)

This provides software applications on demand over the internet on a subscription basis.
