2012 IEEE 6th International Workshop on the Maintenance and Evolution of Service-Oriented and Cloud-Based Systems (MESOCA)

Cloud computing is an emerging computing paradigm whose benefits (such as high scalability, reduced IT costs, self-service on demand, and pay-as-you-go price models) have increasingly attracted the interest of the corporate world. Nevertheless, many organizations have found it difficult to adopt cloud-based solutions, particularly regarding the migration of their existing legacy applications to th... View full abstract»

The purpose of the work described here is to support the reuse of existing software systems in a SOA environment by linking a description of existing programs to the overlying business processes. It is one thing to technically wrap the legacy code. It is another matter to connect the code interface definition to the business processes. The SoftLink tool is under development to bridge that gap betw... View full abstract»

During the past few years we are witnessing a paradigm shift in enterprise computing, from the classic host-based service-oriented architecture pattern, to a more complex or elastic computing pattern that facilitates the provision of on-demand computing resources. This new computing paradigm offers numerous advantages but also, poses significant challenges. Advantages are related to the flexibilit... View full abstract»

The evaluation of competing cloud deployment options (CDOs) forms a major challenge when migrating software systems to cloud environments. For example, there exists a plethora of potential cloud provider candidates, components must be mapped to suitable virtual machine instances, and, to exploit elasticity, appropriate runtime adaptation strategies for specific usage profiles have to be defined. B... View full abstract»

In the transition of applications from the traditional enterprise infrastructures to cloud infrastructures, scalable database management system plays an important role in efficiently managing and analysing unprecedented massive amount of data. Compared to RDBMSs, NoSQL databases, are more attractive in addressing this challenge. However, it is not easy to manage data in NoSQL database effectively ... View full abstract»

Summary form only given. This opening keynote tells the story of 15 years of experience with SOA and some 5 years with cloud computing in a global enterprise that is one of the technology leaders in its industry. View full abstract»

This presentation introduces an extended cloud computing architecture that satisfies the requirements of several classes of applications. At its core, a cloud is a datacenter that delivers computing resources over the web and allows applications to acquire these resources on demand. However, some classes of applications have special performance and security requirements that cannot be fulfilled by... View full abstract»

Summary form only given. The speed of change in Internet Technologies continues to be impressive and the current “Future Internet” based society increasingly relies on software at all levels. Nevertheless, software systems continue to suffer from aging symptoms caused by the inherent factors of the software modernization process: inevitable; unpredictable; costly; difficult; time- an...
