Distributed and concurrent systems have become common in enterprises, and the complexity of these systems has increased dramatically. The self-adaptive feature can be advantageous for complex systems, because it can acclimate to a dynamically changing environment. To achieve this goal, this paper presents a Self-Adaptive Framework for Concurrency Architecture (SAFCA). SAFCA includes multiple concurrency architectural alternatives and is able to adapt to an appropriate architecture based on changes in the environment and the control policy. With an autonomic control, SAFCA can handle bursty workloads by invoking another architectural alternative at runtime instead of statically configured to accommodate the peak demands, which requires higher system resources even when they are not needed. Experimental results demonstrate that SAFCA can improve performance. The experience can be useful for building complicated systems that have multiple configurations or diverse demands, such as cloud computing.
