If you are someone, who is trying to indulge in a new world of cloud computing then the following content will help you answer all your queries regarding cloud computing. Before starting with the main topic let us understand some of the main terminologies related to cloud computing.
CLIENT
A client is any hardware or software program looking for a specific type of service, for example, if you are looking for a web page on a website then the web browser on your PC serves as a client.
SERVER
A server can be hardware or software that stores a large amount of data within a computer network and processes it whenever a client asks for any service. Servers are of different types depending upon the kind of service asked such as web server, proxy server, application server, and game server. Depending upon the amount of data stored they have two types.
1. Local server– stores information for a specific service
2. Remote server– stores information for a variety of services
CLOUD
In general terms, it is a cloud that stores a large amount of data for a huge firm or any multinational company. More specifically it is a storage house for a large number of servers. No direct contact with the client of any kind. It is a type of remote server.
Now let us understand the term cloud computing,
Cloud computing refers to the on-demand availability of various computing services like data storage, databases, data management, server management, software analysis, and IT expertise to various servers on a large scale over the internet. Today a large number of businesses whether small or large make use of cloud computing to manage their data without getting indulged in the management of their large database or worrying about the management cost of a large number of servers to run their business. The following are the advantages of cloud computing;–
