Example techniques for allocating a candidate server instance for execution of an application instance are described. In an example, a request for allocation of a candidate server instance from multiple server instances is received. The request for allocation of the candidate server instance comprises allocation parameters to uniquely identify the candidate server instance from the plurality of server instances. Subsequently, operational parameters of the candidate server instance are analyzed to determine eligibility of the candidate server instance for execution of the application instance. The candidate server instance is subsequently allocated for execution of the application instance based on the eligibility.
