  1. The future is bright with clouds Hong Zhu Dept of Computing and Communications technology Oxford Brookes University, Oxford OX33 1HX, UK Email: hzhu@brookes.ac.uk

  2. My Position With the rapid development of cloud computing, the future of Software Cybernetics is bright. • What is cloud computing? • What role can software cybernetics play?

  3. Cloud Computing • Cloud computing paradigm is based on an architecture that consists of three sub-models: • Business model • Pay-per-use • Management model • A large amount of computational resource is managed by cloud owner for balance between performance and efficiency • Technology model • A stack of highly complicated computing technology enables elastic scale of computing with rapid development andrapid deployment

  4. A Model of Cloud Computing Automatic and continuous integration and testing, Self-configuration and composition, Self adaptation, etc. Automatic, Autonomic, Self-adaptive, Optimization w.r.t. SLA

  5. Cloud Software Architecture User User User User User User Tenant SaaS Data Data Data Data Data Data Tenant Meta-data Meta-data Building the software for a new tenant is by integration and composition of existing services. Evolution of a service may affect many tenants. Code (service) Code (service) Code (service) Code (service) PaaS Platform Code (service) Code (service) Code (service) IaaS (Cloud infrastructure/hardware)

  6. Challenges to software engineering • Existing theories, methods, techniques, and tools are for human to perform development activities • The ideal solution for developing and maintaining cloud systems require automation: • New measurements and metrics • New processes • New control mechanism/process, etc. These are what cybernetics are all about!
