Distributed garbage collection is responsible for controlling the lifetimes of server applications, and for deleting them when their lifetimes have expired. Traditionally, distributed garbage collection uses reference counts and pinging for control. This works well when there are a few clients per object, but does not work well when there are thousands of clients per each object. The lifetime service can assume the function of a traditional distributed garbage collector, and scales well when the number of clients increases.

The lifetime service associates a lease with each remotely activated object. When the lease expires, the object is removed.
