Aspects of the present invention provide devices that determine a load for each tenant of a plurality of tenants running applications on a shared computer server for a predetermined interval of time, wherein the computer server includes a plurality of computer processor cores, compute a capacity for each tenant of the plurality of tenants which includes a difference between the load and a service level agreement for each tenant, determine computer processor cores corresponding to the capacity of a largest capacity tenant, wherein the processors cores include a subset of the plurality of computer processor cores for the shared computer server, pin the subset of computer processor cores to perform garbage collection for one or more tenants, and invoke the garbage collection using the pinned subset of computer processor cores which deallocates no longer used memory in a corresponding heap for the one or more tenants.

Multi-tenant cloud elastic garbage collector

Embodiments disclose systems, methods and computer program products to perform an operation for sharing artifacts between instances of an application deployed in a cloud computing environment. The operation generally includes upon determining, during staging of the application, that a set of artifacts are not available for instances of the application to share in the cloud computing environment, generating the set of artifacts via a first application instance, storing the set of artifacts, and requesting a re-staging of the application. The operation also includes during the re-staging of the application, generating a file for deploying scaled instances of the application and packing the stored set of artifacts into the generated file via a second application instance. The operation further includes executing an instance scale out of the application with the generated file comprising the stored set of artifacts.
