There are many successful case studies of SOA adoption, mainly in commercial enterprises. Part of what Gartner terms the “period of enlightenment” related to hype cycles for emerging technology is the move from SOA as simply a set of technologies to service-orientation as a mindset for architecting, implementing and deploying services that add value to an organization. Regardless of this positive perception change, there are still two concerns from a maintenance and evolution perspective: (1) deployed service-oriented systems will have to be maintained and evolved and (2) legacy systems will continue to use service-orientation to make their legacy functionality available to other systems and applications.

Cloud Computing is emerging as a new model for system development and deployment, in which systems use resources from — or are hosted, run and managed — in large server farms and data centers, and provided as a service. The lack of control over these external resources creates additional challenges for systems migrating to these environments.

Workshop Goals

The main goal of MESOCA 2011 is to create a focal point and an ongoing forum for researchers and practitioners to share results and open issues in the area of maintenance and evolution of service-oriented and cloud-based systems. MESOCA has its roots in MESOA – the workshop on maintenance and evolution of service-oriented systems – that has been co-located with ICSM for the past four years and explored topics such as reengineering processes, program comprehension techniques, evolution patterns, transition patterns and runtime monitoring. Now, given the increased adoption of cloud computing, the workshop is expanding to address challenges in systems migration to cloud environments.
