A method for improving the performance and availability of a distributed application includes providing a distributed application configured to run on one or more origin server nodes located at an origin site. Next, providing a networked computing environment comprising one or more server nodes. The origin site and the computing environment are connected via a network. Next, providing replication means configured to replicate the distributed application and replicating the distributed application via the replication means thereby generating one or more replicas of the distributed application. Next, providing node management means configured to control any of the server nodes and then deploying the replicas of the distributed application to one or more server nodes of the computing environment via the node management means. Next, providing traffic management means configured to direct client requests to any of the server nodes and then directing client requests targeted to access the distributed application to optimal server nodes running the distributed application via the traffic management means. The optimal server nodes are selected among the origin server nodes and the computing environment server nodes based on certain metrics. |
