With Cloud computing, more complex and mission critical applications are moving to the Cloud so transactional, secure, reliable and highly available databases are a requirement for many Cloud applications. Corporate computing will inevitably become much more distributed than spreading itself across multiple data centers. This will acquire management, architectural and performance challenges - and foster innovation to meet those challenges. GemFire Enterprise is a distributed memory oriented data management platform that pools memory (and CPU, network and optionally local disk) across multiple processes to manage application objects and behavior. GemFire uses dynamic reproduction and data partitioning techniques to offer continuous accessibility, high performance and linear scalability for data intensive applications without compromising on data consistency even when exposed to loser conditions. Besides being a distributed data container, it is an active data management system that uses an optimized low latency distribution layer for reliable asynchronous event notifications along with highly concurrent data structures for storage. This paper looks at what cloud computing and cloud database is. An online system is built as B2C application which has its data stored in CLOUD database GEMFIRE. It's then deployed in eyeOS of a desktop forming a private cloud.
