What is Cloud Computing? How Cloud Computing Works?

What is cloud computing?

Cloud computing means "a type of Internet-based computing," where different services — such as servers, Switches, storage and applications — are provided for you as a service by another company and accessed over the Internet with many additional advantages.

In other words, Cloud computing is providing developers and IT departments with the ability to focus on what matters most and avoid undifferentiated work like procurement, maintenance, and capacity planning.

If you are interested in learning, Request you to go through the below recommended tutorial.

Why do we need Cloud Computing?

When we buy new servers for a Infrastructure, that has to be in the datacenter with proper rack mounting and good power source. Lot of efforts involved in buying a servers, installations, configurations, Patching the servers regularly and setting up in the network and maintaining the infrastructures. This is more expensive and require more efforts.

When you go with Cloud, everything comes as a service very easily. It is more cheaper, more effective and much faster. So no need to focus on the hardwares and maintaining the infrastructures. we save lot of time and money.

Often, virtualization techniques are used to maximize the power of cloud computing.

Let us give you some basic examples

Example 1:

You started a new company. Your new company has a website which is hosted on your server.
Over a period, lot of users are visiting your website at the same time, which causes a poor performance or encountering problems. so you will loose your website popularity and business productivity.

How this can be fixed?

By increasing the memory, cpu and other resources. This is again going to be a big tasks.
But when we have hosted our website on cloud online, we can scale up or scale down the resources when we need which we call it as "ON DEMAND".

Example 2:

Lets say, New project has come and you planned to buy some servers for the new project to develop some programs. That project will be get finished in 3 months. Is that a good idea to buy servers only for 3 months?

What will you do with that server after the completion of the project.

But here in cloud, we buy the servers as a service for the period and this can be extended if need, and we pay only for the use.
