A centralized computing system, comprising a centralized computing center comprising a plurality of nodes, a plurality of clients in different geographical regions, an IP network interconnecting the clients and the centralized computing center, and a scheduler scheduling jobs onto suitable nodes.The plurality of nodes include desktop container nodes, exclusively used for running remote desktop server software, each remote desktop server software communicating visual output to a remote desktop viewer on one of the clients. The system further comprises an accelerator arrangement capable of providing communication of visual output between the desktop container nodes and the clients using an alternative transport layer protocol other than transmission control protocol (TCP), the alternative transport layer protocol being more efficient than TCP over a high-latency connection.
