Despite of the fact that cloud provides a number of benefits, dangers associated with it cannot be unseen. One of the biggest dangers that the cloud providers are facing today is the vast amount of traffic that is increasing nearly in fraction of nanoseconds [1]. Cloud Service Providers need efficient ways to distribute data or better called resources across wide area network (WWW). Large scale, geographically replicated online services provide new opportunities for coordination between servers (to match clients with servers), traffic engineering (to efficiently distribute traffic on different paths), content placement (to place data on specific servers for load balancing). Traditional designs tend to isolate the above problems in traffic management, thus degrading the performance, reliability, responsiveness and scalability [2]. To tackle with the increasing traffic, we are proposing the theory of decentralized optimization, game theory and approximation algorithm to jointly provide solutions to these design problems that are controlled by different institutions of CSP. KEYWORDS: Cloud Computing, Cloud Service Provider, Traffic Engineering, Server Selection, Content Placement INTRODUCTION In the starting the cloud traffic was usually managed by individual entities, protocols such as MPLS came into existence after that for traffic management and were somehow successful. Traditionally traffic management was done separately by four parties that collectively make up cloud ecosystem. An illustration has been shown in the figure 1 given below:  Internet Service Provider Internet service providers are the network providers that provide connectivity or bandwidth to transport data simply treating them packets [3]. The primary role of an ISP is to manage traffic by deploying infrastructure, manage connectivity and load balancing.  Content Distribution Network Content Distribution Networks provide the infrastructure to replicate content across geographically-diverse data centers (or servers). Today's CDNs strategically deploy servers across geographically distributed areas, and replicate content over a number of designated servers. CDNs solve a server selection (SS) problem.
