Abstract: A method for upgrading computing devices in a distributed computing environment is provided. The method includes receiving first and second rollout requests for a cluster relating to operational actions for computing devices associated with the cluster. A rollout status for the cluster is determined and the rollout requests are simultaneously performed on the cluster where the operational actions are simultaneously performed on the computing devices associated with the cluster. In addition, a rollout status is updated based on simultaneously performing the rollout requests for the cluster.

Abstract: Methods and systems for managing application performance in a distributed computing environment. Embodiments commence when an application seeks to perform a function over a content object. The application submits a request to perform the function on the content object, and the request is received by an application programming interface processor. The application programming interface processor accesses a data structure comprising entries that relate the requested function to one or more code instances that are accessible at one or more code locations. An evaluator predicts performance of the function using a first location of a first code instance and compares that predicted performance to a predicted or measured performance of the same function using a second location of a second code instance that implements the same function. The better performing code instance at the determined code location is invoked. Results are collated, formatted, and returned to the calling application.

Abstract: A queue in a connector service provides a unified communication channel and stores service packets sent to a target service from client applications. Incoming service request packets are modified at run time to add valid security tokens without requiring the user's action or notice. Before sending the packets, the connector service determines whether the authentication tokens are valid. Packets with valid authentication tokens are sent to the target service. If the communication request fails, the queue automatically adds the original communication packet to the end of the queue, so that it can be conditionally retried. When a loss of connectivity is detected, the connector service takes a snapshot of the queue by copying the packets to a storage module in the same order. When the connectivity is restored, the queue loads the saved requests from the storage module and starts processing them in the order they were received.
