Abstract: 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.

Abstract: An aspect of the present disclosure facilitates third parties/server system to perform batch processing of requests requiring authorization from resource owners for repeat access to resources. In one embodiment, a server system/third party selects a next request from a batch of requests, with the next request requiring a protected resource (hosted on a second party) owned by a owner/user (first party). The server system checks whether an access token is present authorizing access of the protected resource by the server system on behalf of the owner. If the access token is not present, the server system communicates in an offline mode with the owner to receive the access token. The server system then processes the next request by accessing the protected resource using the present/received access token.
