Cloud computing is an emerging practice that offers more flexibility in infrastructure and reduces cost than the authors' traditional computing models. Cloud providers offer everything from access to raw storage capacity resources to complete application services. The services that are provided by the cloud can be accessed from anywhere and data flows from one place to another. Since data is moving via network, there are chances of data loss. So they need to keep multiple copies of data and thus data replication is one of the main issues in cloud computing. In this paper, they have implemented automatic replication of data from local host to cloud environment. Data replication is implemented by using HADOOP which stores the data at various nodes.
