Cloud Server Management Method with Random Remote Backups

Kim Song-Kyoo
Abstract—A Cloud service provides the use of computing resources (hardware and software) that are delivered as a service over a network. The name comes from the use of a cloud-shaped symbol as an abstraction for the complex infrastructure it contains in system diagrams. Cloud computing entrusts remote services with a user's data, software and computation. This paper is dealing with the stochastic Cloud server management method which is focused on reliability. The (remote) backup cloud servers are hooked up by the long-haul network and replace broken main cloud severs immediately. If the Cloud servers are represented as "machines" this system can be solved by using the stochastic maintenance model with main unreliable and random auxiliary spare (remote backup) machines, subject to random breakdowns, repairs and two replacement policies: one for busy and another - for idle or vacation periods. When the repair facility is not available because of the given conditions, auxiliary machines are being used for backups. Unlike existing models, the availability of auxiliary machines is changed for activations of the system. Analytically tractable results are obtained by using a duality principle, semi-regenerative analysis, and multi-variate marked renewal processes. The results are demonstrated in the framework of optimized Cloud server allocation problems with unreliable backup servers.

Index Terms—Stochastic maintenance, cloud service management, availability, stochastic optimization, closed queues, duality principle.
