Service discovery and renaming

Abstract:

A provider network implements service discovery and renaming. A provider network includes a domain name service (DNS) and a renaming tool. The DNS receives queries for service names and sends query logs to a data store. Each query log indicates the queried name and a network address (e.g., IP address). A user may request that the service be renamed to a new name. In response, the renaming tool adds a new entry to for the new name to the DNS. The renaming tool retrieves data from the query logs and identifies clients of the service. The renaming tool sends a notification to the identified clients that the name has changed to the new name. The renaming manger retrieves additional data from the query logs to identify how many of the clients have switched to using the new name. After enough clients have switched, the old name may be decommissioned.
