Before learning about Cloud Computing let’s learn about cloud.
The term Cloud refers to a Network or Internet. Cloud can provide services over network i.e. on Public Networks or on Private Networks i.e. WAN – Wide Area Network , LAN – Local Area Network.
Applications such as Email, Web Conferencing, Customer Relationship Management (CRM), all run in cloud.
It is defined as a mode for enabling convenient, on-demand network access to a shared pool of configurable and reliable computing resources like Networks, Servers, Storage, Application, Services etc that can be manipulated, configured and accessed remotely.
It offers platform independency, as the software is not required to be installed locally on the PC. Hence, it is making our business applications, mobile and collaborative.
Cloud Computing Architecture comprises of many cloud components, each of them are loosely coupled. We can broadly divide the cloud architecture into two parts:
Front End:Front End refers to the client part of the computing system. It consist of interfaces and applications that are required to access the the computing platforms. Example: Web Browser
Back End:Back End refers to the cloud itself. It consist of all the resources required to provide cloud computing services. It comprises of huge Data Storage, Virtual Machines, Security Mechanism, Services, Deployment Models, Servers etc.
