Abstract

A PaaS Cloud is expected to provide an environment for users to install and deploy the application in which each tenant is isolated from co-tenants and one tenant is not allowed to interfere with the performance of the co tenants by over-utilizing of hardware resources. PaaS tenants most often run on shared Virtual machines or physical nodes whose performance is dependent on the underlying resource limitations as well as the actions performed by other tenants. The cloud service provider is expected to maintain certain Quality of Service (QoS) as per the SLAs. PaaS cloud services are implemented in high-level languages like Java which provide features for automatic memory management policies such as Garbage Collection (GC) which can affect the QoS. The language runtime implements various policies and algorithm to conduct a GC which can hamper the servers ability to maintain accepted levels of QoS. This paper attempts to investigate which GC policies performs best and has lowest interference in a PaaS cloud environment.
