Cloud computing is the latest technology evolution and labelled among many as the next potential technology silver bullet. There are both great expectation and fear to what consequences these technologies might cause. We want to engage the development community in a series of workshops at OOPSLA09 to ensure that cloud computing evolves in a meaningful way for those who are likely to develop solutions on the cloud. This workshop will focus on operational implications. Due to the potential rapid availability of services in the cloud it is important to start exploring consequences of using such services, for instance access control, regulatory issues, development practices, security and practical operational issues. Capturing and discussing best practices on these subjects will contribute to a healthy movement in the right direction for those who will develop services for the Cloud.
