Monitoring services quality in the cloud

Abstract:

Due to the dynamic nature of cloud computing environments, continuous monitoring of the quality of cloud services is needed in order to satisfy business goals and enforce service-level agreements (SLAs). Current approaches for SLA specifications in IT services are not sufficient since SLAs are usually based on templates that are expressed in a natural language, making automated compliance verification and assurance tasks difficult. In such a context, the use of models at runtime becomes particularly relevant: such models can help retrieve data from the running system to verify SLA compliance and if the desired quality levels are not achieved, drive the dynamic reconfiguration of the cloud services architecture. Cloud computing represents much more than an infrastructure with which organizations can quickly and efficiently provision and manage their computing capabilities. It also represents a fundamental shift in how cloud applications need to be built, run and monitored. While some vendors are offering different technologies, a mature set of development tools that can facilitate cross-cloud development, deployment and evaluation is yet to be developed. This definitely represents a growth area in the future. The different nature of cloud application development will drive changes in software development process frameworks, which will become more self-maintained and practice-oriented.
