Scaleable and extensible system management architecture with dataless endpoints

摘要

A large distributed enterprise includes computing resources that are organized into one or more managed regions, each region being managed by a server machine servicing one or more gateway machines, with each gateway machine servicing a plurality of endpoint machines. A distributed system management framework is supported on the gateway machines and the one or more endpoint machines to carry out system management tasks. To enhance scalability, the endpoint machines support a low cost, low maintenance client component of the system management framework, and a corresponding server component is supported on each of the gateway machines. On an as-needed basis, appropriate executable code and system management data is delivered from a gateway to one or more endpoint machines to facilitate execution of a system management task for the managed region. Typically, the system management data is not stored in the endpoint, and this "dataless" approach reduces the complexity and maintenance costs associated with distributing the functionality of the system management framework. The endpoints are easily extensible to include new application functionality without requiring the overall framework to be rebuilt or reinstalled.
