DevOps and continuous deployment require the implementation part of service transition to be highly automated so it can deal with high-frequency transition and provide better quality control.

Let Rs and Rc be the rate of each link as shown in the figure above. In case of Rs [1] Rc, The backlog of bits at the router waiting for transmission to the client will grow and grow. Assume the throughput of this network is found to be P bps. The time it takes to transfer a file of F bits from server to client in the above network should be [2].  (First blank must be a relational operator like =, >, =,
