Embodiments of the present disclosure relate to availability level-based service management. In an embodiment, a computer-implemented method is disclosed. According to the method, it is detected initiation of a request from a first microservice to a second microservice. The first and second microservices are comprised in a plurality of microservices of an application. The request comprises an expected availability level for the application. In response to a current availability level of the application being higher than or equal to the expected availability level and in response to determining that the execution of the second microservice is unavailable, the request is caused to be routed to a simulated microservice of the second microservice. The simulated microservice is configured to return to the first microservice a dummy response to the request. In other embodiments, a system and a computer program product are disclosed.
