DEPLOYING SERVICES ON APPLICATION SERVER CLOUD WITH HIGH AVAILABILITY

摘要

Techniques are disclosed for deploying services in a server cluster environment. Certain techniques are disclosed for deploying services to a cluster based on a replication policy that includes a plurality of configurable parameters. In some embodiments, the configurable parameters (also referred to herein as replication factors) can define a number of nodes to which a service is to be deployed, a number of nodes to which a service is to be prepared, and/or a number of nodes to which a service is replicated. Based on the configurable parameters, the replication policy enables users and/or cluster providers to guarantee different levels of performance and/or reliability.

1. A method comprising:
receiving, by a computer system, a replication policy including a plurality of replication factors; deploying a service to a first set of nodes in a server cluster based on a first replication factor; preparing the service on a second set of nodes in the server cluster based on a second replication factor; and replicating the service to a third set of nodes in the server cluster based on a third replication factor.
