Abstract
The present disclosure generally relates to enabling migration of services between a first and second environment, while maintaining a local availability of those servers within the first environment. Specifically, embodiments enable the services to remain locally available with the first environment without modification of operation of clients within the first environment. A migration gateway is provided in the first environment that, on migration of a service from the first to the second environment, can announce availability of the service at the gateway. The gateway can then act as a proxy for the service in the second environment. In one configuration, the gateway adopts an Internet Protocol (IP) address of a server that has been migrated, such that clients may be unaware that migration has occurred.
