Cloud Storage is a service that allows to save data on offsite storage system managed by third-party and is made accessible by a web services API. It typically has two aspects: Modern QA practices host multiple applications, ranging from those that run for a few seconds to those that run for longer periods of time on collective hardware platforms. Securing the Cloud is the first book that helps you secure your information while taking part in the time and cost savings of cloud computing. is a Cloud computing platform at which user can develop social enterprise applications. With the increasing size of big data, refining big data themselves to reduce data size while keeping critical data (or useful information) is a new approach direction. This model offers the versatility and convenience of the cloud, while preserving the management, control and security common to local data centers. can collaborate with each other using the shared storage. Computer simulation reveals that the proposed mechanism is more flexible and efficient than the callback scheme typically employed for lock control and centralized locking mechanism. It started as the ability to run multiple operating systems on one hardware set and now it is a vital part of testing and cloud-based computing. The concept of cloud computing is described by Jie et al. The communication cost of the proposed scheme is smaller than the callback scheme by adopting the blocking approach with a wait queue to eliminate spin-lock.
