Abstract: Various examples are directed to systems and methods for operating a database management system. A first host of a first version may be executed at a first container of a cloud environment. A second host of a second version may be executed at a second container of the cloud environment. The first host may be configured to perform a source role and the second host may be configured to perform a replica role corresponding to the source role. A network layer executing at the cloud environment may receive a request directed to the second host. The network layer may determine that the request is consistent with allowed request data describing allowed requests and may send the request to the second host.
