REPLICATING CONFIGURATION BETWEEN MULTIPLE GEOGRAPHICALLY DISTRIBUTED SERVERS USING THE REST LAYER, REQUIRING MINIMAL CHANGES TO EXISTING SERVICE ARCHITECTURE

摘要

Replicating configuration among distributed servers. A filter running on a server, the server being one of the distributed servers, intercepts a request from a client device to the server. The filter creates a unique identifier for the request and blocks the request from being processed at the server. A replicator running on the server sends the request with the unique identifier for synchronizing the request with one or more other requests received from one or more of the distributed servers. The replicator also receives an ordered list of one or more synchronized requests each annotated with a respective unique identifier. The server processes the ordered list of one or more synchronized requests having the respective unique identifier. The ordered list may include the request that is being blocked, wherein the blocked request is processed at the server responsive to receiving request as part of the ordered list.

主权项

1. A method of replicating a configuration update among distributed servers, comprising:
intercepting a request from a client device to a server; creating a unique identifier for the request; blocking the request from being processed at the server; sending the request with the unique identifier for synchronizing the request with one or more other requests received from one or more of the distributed servers; receiving an ordered list of one or more synchronized requests each annotated with a respective unique identifier; processing the ordered list of one or more synchronized requests having the respective unique identifier, the ordered list comprising at least the request that is being blocked, wherein the blocked request is processed at the server responsive to receiving the ordered list of one or more synchronized requests.
