This is not a new technology, but the concept that binds different existed technologies altogether including Grid Computing, Utility Computing, distributed system, virtualization and other mature technique. Business Process Management (BPM) is designed for business management using IT infrastructure to focus on process modeling, monitor and management. BPM is composed of business process, business information and IT resources, which help to build a real-time intelligent system, based on business management and IT technologies. This paper describes theory on Cloud Computing and proposes a BPM implement on Cloud environments.展开更多

After SLA contraction, it should be monitored during the service invocations to confirm the service level objectives. Most of SLA structure and monitoring frameworks are brought from SOA and grid computing to cloud computing environment while they have different requirements. In this paper, a model is proposed as hierarchical autonomic (HA)-SLA based on cloud computing nature. It is proposed in this model that each SLA has connection with dependent SLAs in different layers of cloud computing, hierarchically, whereby each SLA should be able to monitor its attributes on its own. It is expected that HA-SLA model should able to increase SLA validity and users’ confidence without compromising the respond time. The results produced by this model should be used as one of cloud computing quality of service assurance.展开更多
