Fault isolation and identification in versioned microservices
A method for identifying and isolating faults in versioned microservices includes a request replicator receiving an original request, and determining whether to replicate the original request. The request replicator replicates the original request creating one or more replicated requests, including a first replicated request. In an example, the request replicator dispatches the original request to a stable production system, and dispatches the first replicated request to a first modified production system. The stable production system produces a first reply to the original request. The first modified production system produces a second reply to the first replicated request. A fault detector performs a comparison of the second reply and the first reply and determines, based on the comparison, that the first modified production system has a verification status. Then, the stable production system is replaced with first modified production system.
