Collaboration service to support cross-process coordination between active instances of a microservice
Techniques are provided for enabling cross-process coordination between multiple instances of given microservice in a cloud computing system. A method includes running a plurality of active instances of a given microservice of a computing system comprising a distributed microservices architecture. A first active instance of the plurality of active instances executes a portion of program code of the given microservice to perform a job. The portion of the program code of the given microservice includes an instance synchronization element which is configured to enable cross-process coordination between the plurality of active instances of the given microservice with the support of a collaboration service. The first active instance utilizes the instance synchronization element to communicate with the collaboration service and cause the collaboration service to execute a process associated with the instance synchronization element to thereby implement the cross-process coordination between the plurality of active instances for executing the job.
