System Management and Operation for Cloud Computing Systems

With the progress of virtualization technology, cloud systems have been started to be deployed on a full-scale basis. However, there are many issues in terms of managing cloud systems in a stable and high-quality way. This is because the number of servers becomes immense and dependencies between servers become complex. Conventionally, individual business applications and services have been operated in systems. However, in the cloud there is a degree of uniformity in the infrastructure that makes up systems. Consequently, there are hopes that it will be possible to prepare common management platforms and methods such as those to manage application life cycles and predictive failure detection technology. This paper introduces technology that integrates the development and operations management phases in the PaaS region by leveraging such characteristics of clouds. This technology functions according to the characteristics of the applications or individual service level agreements (SLAs), and makes it possible to configure applications that are deployed on the cloud. This paper also introduces technology that allows operators to automatically or simply build a test environment the same as the real environment when changing applications and run automated tests. In addition, this paper touches on technology to monitor and visualize work that is core technologies for the life cycles management. Moreover, this paper describes technology that can conduct statistical processing of the logs that are issued from the system during operation to detect the prediction of failure phenomenon.
