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 design implications. Although there is already strong support for these technologies from companies such as IBM and Microsoft, there is a need to explore good ways of designing services for the Cloud to ensure quality and productivity. There are movements in the modeling community that require further investigation as well as surviving concepts from the SOA era that need to be captured. 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.
