The computational humanity is flattering extremely bulky and multifaceted. Cloud computing is becoming one of the most expanding methodologies in the computing industry. It is a novel approach for the deliverance of IT services on the World Wide Web. This model provides computing resources in the puddle for consumers, all the way through Internet. In cloud computing, resource allocation and scheduling of numerous aggregate web services is an imperative and demanding quandary. This paper estimates the various network resource allocation strategies and their applications in Cloud Computing Environment. A brief description for network resource allocation in Cloud Computing, based on differentially adapted dynamic proportions, has also been done. This paper addresses and categorizes the foremost challenges normal to the resource allocation progress of cloud computing in terms of diverse types of resource allocation techniques.
