“…In the context of adaptive cloud platform resources configuration, the use of virtual machine migration will lead to the equal reduction of service availability and will not exceed 5-10%, and with the service nodes count above 40 it becomes insignificant. Note, that high levels of self-similarity are intrinsic to the internet traffic generation services -H~0.685, IP-telephony -H~0.981, Video-on-Demand (VoD) -H~0.608, service data transmission -H~0.719 [28]. Taking Amdahl's law into account, we claim that cloud system clustering allows to achieve the maximal effectiveness for cluster size not less than 100 nodes, which comes out from the results of service availability simulation.…”

“…Despite the high level of well-known methods for increasing availability of service systems, cloud systems are still a subject for bottleneck analysis. The main purpose is to increase their operation robustness, service availability and overall performance [6,28]. The relevance of research on the subject is rather high.…”

This paper is devoted to the quantitative investigation of the availability of cloud service systems. In this paper we calculate the criteria and constraints of a distributed service platform such as availability and system performance index variations by defined set of the main parameters. We analyze the calculation results to enable optimal synthesis of distributed service platforms based on the cloud service-oriented architecture. The method of synthesis has been numerically generalized considering the type of service workload. We used Hurst parameter to statistically evaluate each integrated service that requires implementation within the service delivery platform. The latter is synthesized by structural matching of virtual machines using combination of elementary service components. According to Amdahl's Law the clustering of cloud-networks allows to break the complex dynamic network into separate segments that simplifies access to the resources of virtual machines. This in turn simplifies complex topological structure, enhancing the overall system performance. The proposed approaches and obtained results allow to numerically justify and algorithmically describe the process of structural and functional synthesis of efficient distributed service platforms. These platforms through dynamic configuring and exploitation provide an opportunity to create the dynamic environment in terms of comprehensive services range and significant user workload fluctuation.
