High-availability framework for services in provider network environments

Abstract:

A high-availability (HA) framework for services deployed in provider network environments. Services may be deployed as machine images or containers to a provider network. The HA framework provides a "wrapper" around the deployed services that provides feedback loops and flow control for inbound and outbound communications to other services on the provider network or to other external entities. The HA framework intercepts inbound and outbound traffic to the service, and may automatically determine, configure, and adjust networking management aspects such as timeouts, flow control, etc. for the service. The HA framework may also intercept outbound traffic to monitor outbound connections to other services to determine if the services satisfy HA requirements of the service.
