A Novel Solution of Cloud Operating System Based on X11 and Docker

With the fast development of cloud technologies, cloud-based operating systems are becoming increasingly popular, while several enterprise products, such as Chrome OS and SUNDE, are released continuously. According to the way of usage, the existing cloud-based operating systems can be divided into two categories: browser-driven operating system and virtualization-based operating system. However, traditional cloud-based operating systems have some disadvantages: As the functionality of browser is limited, it is difficult to transplant traditional desktop software to browser based cloud operating system; on the other hand, as for systems which are based on remote virtual machines (VMs) and Virtual Network Console (VNC), the system performance is constrained by the limited network bandwidth, which will also lead to performance degradation. To solve these problems, this paper designs AntOS, a full-featured cloud operating system. AntOS takes advantage of Docker and X11 technique, to reduce the load of network over 50% while increasing CPU utilization by 45%, which can effectively support the private cloud scenario in enterprises.
