In traditional client/server applications, the client connects with the database directly, and the connection is kept open until the DISCONNECT statement is executed.
In PowerBuilder installable cloud apps, PowerServer connects with the database and supports the connection pooling. Existing database connections can be cached in the pool and shared by applications. And the database can reside in the local area network (LAN). PowerServer accesses data through .NET Core Web APIs and transfers data securely by implementing the industry-standard authorization framework (such as OAuth 2.0, JWT etc.).
