A secured load balancing architecture for cloud computing based on multiple clusters

Cloud computing is one of the new and very promising trends in the IT technology field, it is subject to a lot of research and continuous advances are made. Its main objectives are to deliver different services for users, such as infrastructure, platform or software with a reasonable and more and more decreasing cost for the clients. To achieve those goals, some matters have to be addressed, mainly using the available resources in an effective way in order to improve the overall performance, while taking into consideration the security and the availability sides of the cloud. Hence, one of the most studied aspects by researchers is load balancing in cloud computing, especially for the big distributed cloud systems that deal with many clients and big amounts of data and requests. In this paper, we address the subject of load balancing in cloud computing and present a semi centralized and multi cluster architecture. This proposed approach mainly ensures a better overall performance with efficient load balancing, the continuous availability and a security aspect.
