A computer implemented method manages connections. A number of processor units monitor connection requests to access a set of backend resources. The number of processor units identify request groups for the connection requests based on authentication data in the connection requests. The number of processor units analyze the connection requests to identify a usage trend for connections by the request groups. The number of processor units predict the usage trend of the connections for a period of time to form a predicted usage trend for connections in the period of time. The number of processor units manage a connection pool based on the predicted usage trend for the connections in the period of time.
