Described herein is a system and method for supporting a webtier provider in a cloud computing environment. In accordance with an embodiment, the service types made available in a cloud platform (e.g., CloudLogic) domain can include information which describes dependency on a webtier provider, which in turn provides load-balancing capability to a service whose deployment may span multiple virtual machines. A webtier provider can associate one or more provisioned services with a webtier runtime, to satisfy the webtier dependency of a service. After a service is provisioned, a webtier provider service management engine (SME) can associate the service with a webtier runtime by creating a configuration therein. The webtier runtime can subsequently provide a single point of access to the service, including load-balancing requests to service nodes, or providing support for additional capabilities such as failure detection and failover.
