what is cloud computing for beginners

In simple terms "cloud computing" means accessing the database resources via internet.the best examples are Google applications,Facebook,etc..,let me explain in clearly if you're searching an article in Google search it will retrieve the necessary information from their databases via internet this is called cloud computing.At the same time if you post an article in Facebook it will be store the data in their databases via internet this is also called "cloud computing".


The major advantages of using Cloud Computing in Aspnet applications


1)By using cloud computing we can store large amount of data from anywhere without worrying about their maintenance.


2)Transfer the data from one server to another server,no need to worry about server types that means we can move the data from Unix based machine to Windows


3)if we are using the Cloud computing for our aspnet application,there is no change in the performance in our aspnet application if traffic raises high.


4)Thousands of virtual machines and applications can be managed more easily using a cloud-like environment.



Types of cloud computing


There are three types of cloud computing - public cloud, private cloud and hybrid cloud.


what is public computing.?


Public cloud- this is considered as a main-stream cloud system by cloud computing experts and it is most popular also. In public cloud system ,A third party data center provide both disk space and computing power for all the application software. Google apps and Amazon web is the two most popular public cloud computing service providers.


what is Private computing.?


Private cloud- Private cloud is different from public cloud, Here we need to set up our own data center and also bear all the installation & maintenance cost, and at the same time we have complete control of all our data. when compared to Public cloud this system provides more security and privacy, but it is more expensive cloud solution to public cloud.


Cloud Computing Architecture


Cloud computing system can be divided into 2 sections,


one is Front end and another one is Backend. The front end is the interface for the user example client and the back end is the cloud section for the whole system. Front end and Backend connected with each other via network like internet.


There are 3 types of layers related to Cloud services


Cloud Infrastructure Services (Infrastructure as a Service “IaaS”):


This service provider bears all the cost of servers, networking equipment, storage, and back-ups.Rather than purchasing servers, software, data-center space or network equipment, clients instead buy those resources as a fully outsourced service.


Cloud Application Services (Software as a Service “SaaS”):


This service provider will give your users the service of using their software, especially any type of applications software.Google Apps., Salesforce.com,and various other online applications are use cloud computing as Software-As-Service (SAAS) model.


Cloud Platform Services (Platform as a Service “PaaS”):


Platform cloud services are used by software developers to build new applications and by operations managers to manage their application, compute and storage cloud services.


I hope this will helps you...
