maintaining an active generation value that indicates a first immutable instance of a database system is permitted to write data to a database, wherein an immutable instance includes a set of database servers that manage data of the database, and wherein the first immutable instance is assigned a first generation value;
receiving a request to deploy, to a database cluster having the first immutable instance, a second immutable instance of the database system;
deploying the second immutable instance to the database cluster, including assigning a second generation value to the second immutable instance; and
updating the active generation value to cause the first immutable instance to shut down based on the first generation value and the second immutable instance to begin writing data to the database based on the second generation value, wherein the updated active generation value indicates that the second immutable instance is permitted to write data to a database.
