A fundamental disadvantage of server-centric architecture is an enterprise planning environment is that applications must maintain an open session on the server until all transactions are complete, which can drastically reduce server capacity and degrade performance during peak load times. Furthermore, in server-centric architectures, *plan contributors* who are traveling or otherwise disconnected from the network cannot interact with the plan until they reconnect to the server.
It consumes only modest bandwidth and doesn’t bring a server to its knees when hundreds of *plan contributors* simultaneously scramble to meet a plan or forecast deadline
