What is cloud computing?

What is cloud computing?
It is the use of remotely located servers on the internet to store, manage, and process data rather than a local server or personal computer.

For example, when we run a business,  we need numerous servers. In this event, we hover between two options either we can purchase or rent those servers to store, manage, and process. To rent it rather than purchasing called cloud computing. On account of rent, we get the password and allotment of server memory.

Why cloud computing?

We need a host website. To maintain high traffic, we need more servers.
We are ought to monitor and maintain these servers.

Set up without cloud computing has multiple disadvantages

1. All this going to cost very high because servers will be on their own expenses.

2. We need a different unit in the company to troubleshoot in case of any disorder occurs.

3. Since numbers of the user constantly vary, it does perpetuate high traffic every time and remains idle.

To avoid these disadvantages we use cloud computing.

 1. You can rent servers on an hourly basis rather than purchasing.

 2. You don't need to deploy a workforce for troubleshooting or any other related problem.

 3. You can easily scale up the numbers of servers to manage high traffic and vice-versa.

 4. Here, Your cloud provider manages the server, hence you can pertinently focus upon expansion of your business.



There are two different models of cloud computing
1. Service Models: the kind of services that the cloud offers.
2. Deployment Models: how can you deploy or upload your application.



Service Models: there are three types of servicing model, namely
1. Infrastructure as a service:
2. Platform as a service
3. Software as a service


1. Infrastructure as a service:
They will give you the password, IP address, or a complete system to work that you can make the webserver or database server as per need. You get complete control over the operating system, storage, and server.

It provides virtualized computing resources over the Internet.

No varies about the underlying physical machine.

It abstracts the users from the physical machine.


2. Platform as a service: you don't get control over the operating system, storage, and server in this case. You get access to the user interface. Because they don't provide here the IP address and password to you. Here, you just have to upload your file or application through programming languages and tools provided by the cloud provider.


3. Software as a service: here, you get neither server nor user interface but a software.

Deployment models also consist of 3 types
1. Public cloud: when you are sharing your server with a host of different people.

2. Hybrid cloud: it is a mixture of both the public and private clouds.

3. Private cloud: if you want a stand-alone server, you should opt private cloud.
