Abstract: The main functionality of Cloud is to provide multiple resources to the users. Storing the data in the Cloud one of the major advantage. The hacker or the Bot master will try to access or try to gain information of the data which is stored in the Cloud, by sending multiple requests to the system. When the number of request exceeds the servers limit, the server will not be able to process the incoming request and the server may crash. The main aim of the paper is to create a framework for Cloud resilience system, which have the ability to provide the service for the clients even when the system is flooded with multiple request. When the incoming request exceeds the limit then the server will not be able to process the request and may crash. In order to prevent the server from crashing, a Stealthy DDos Detection Mechanism has been introduced. In this mechanism, the server monitors the number of incoming request given by each individual user. The server is initially given a limited amount of capacity to process the request of a single IP address. When the server load increases it checks all the request given by each user, if the request given by an individual user exceeds the servers limit then all the request from that particular IP address is blocked and all the services which are provided to that IP address is also denied.
