Web Services & Database Services Availability through Multi-Cloud Environment

Cloud computing is one of today's most exciting technologies due to its ability to reduce costs associated with computing while increasing flexibility and scalability for computer processes. During the past few years, cloud computing has grown from being a promising business idea to one of the fastest growing parts of the IT industry. Developed system is a technique through cloud computing in which user will handle systems from far distances with the help of centralized server and can access applications as well insert them from client machines, and can store data on data storage area on proxy server. The main advantage of cloud computing over the other nonnetwork methods is of faster processing. Also, many processors can be used remotely, without the knowledge of the users, in order to expedite the processing. Thus, keeping this main advantage in mind, the main reason for creating the project is to provide a centralized compiling scheme for organizations or institutions. Also, it will act as a centralized repository for all the codes written. The other major advantage that this system will have over the others is that it will make the users system lightweight. The proposed system will be used by an organization to compile and execute code on centralized compiler. Users don’t have to install compiler on each machine. The proposed system will also be used for conducting online exanimation. Keywords— Cloud computing, single cloud, multi-clouds, cloud storage, data integrity, data intrusion, service availability .
