A note on resource orchestration for cloud computing

The special issue of Concurrency and Computation: Practice and Experience (CCPE) compiles a number of excellent technical contributions in the areas of orchestrating cloud resources, composing new cloud services from existing ones, increasing energy efficiency via cloud resource orchestration, and developing cloud-based image processing solutions. The paper titled 'A Service Evaluation Method for Cross-cloud Service Choreography' proposes a multifunctional specification solution for cross-cloud service choreography. This solution is based on a mixed integer programming model for multifunctional specification/identification that decomposes global resource and application constraints into local constraints. The paper titled 'AutoSLAM ? A Policy-based Framework for Automated SLA Establishment in Cloud Environments' proposes a policy-based framework for the automated establishment of SLAs in open, diverse, and dynamic cloud environments. The paper titled 'Minimizing Total Busy Time in Offline Parallel Scheduling with Application to Energy Efficiency in Cloud Computing' addresses this problem by modeling and formulating an energy efficient resource scheduling algorithm.
