Fuel injector for supplying fuel to a combustor

A method, system and computer program product for providing a service to multiple tenants of an application. Responsive to receiving from a client of a tenant a request, a tenant context of the tenant is bound to the request. With respect to an access to an isolation point of the application in the request, the access to the isolation point is redirected to a partition based on the tenant context bound to the request. The partition may be pre-established for the tenant with respect to the application. Hence, it is possible to provide a multi-tenant solution in a convenient, fast, and cost-effective way, and, in turn, to achieve resource sharing to a greater extent and enhance the resource efficiency.
