           The front end layer is the one you can see and interact with and the back end layer is the layer that you can neither see nor interact with. Actually, it has an architecture of hardware and software, which helps to show you the front end layer.

            If you understand this from an example, you must be using Gmail, no matter how much data will be stored in it. Have you ever wondered where this data lives? Actually Gmail, Facebook, YouTube etc. all keep your data saved in cloudstorage. Whenever you enter your login ID and password, you get access to your cloud store.

           You are given 15 GB free cloud storage in Gmail, which you can access from any device by entering your login ID.

 Uses of cloud computing


           You can and do use cloud computing in many things, even if you don't realize it.

           If you use the online service to send emails, edit documents, watch movies or TV, listen to music, play games and other files, we can say that all this is possible only with cloud computing. Has been found.

           The first cloud computing services are barely a decade old, but already different types of organizations are adopting such technology for all sorts of reasons, from small startups to global corporations, government agencies to no avail.

Types of cloud computing


There are mainly four types of cloud computing.

Private Cloud Computing :

          As you can know by its name, it is private so private, no one can use it except you. You can access it yourself by entering your login ID and password. An example of this is Google Drive where all your work items are protected by your email id and password. No one else can use it except you.

Public Cloud Computing :

          As its name suggests, it is in the public domain. This means anyone can use it for their own use. Public cloud is available to every common person, for example, if you are able to download a song on a site, then every normal person can also download it. This means that everyone has access to it. In public cloud computing, you can use this storage without any login.

Community Cloud Computing :

          This type of cloud computing is for members of a single group. Some selected people have access to its data. Let us understand this with the help of an example. Suppose you work in an office, then only you and some employees will have access to the office data. In the same way community cloud computing also works. Few people have access to data in it.

Hybrid Cloud Computing :

         Hybrid cloud uses both public cloud and private cloud together, for example, websites where some data is publicly available but login to access some data It is necessary to do. Hybrid cloud computing is used in such a website.
