Frameworks for service level agreements (SLAs) have been developed to allow services to discover and negotiate SLAs dynamically, without direct human intervention. We give a description of the expe- riences of two projects which are building on existing work in SLAs: the main advantages being to obtain better overall services (including pricing) for the consumer, and the SLAs are useful as a component of, or extension to, cloud federations. We also argue that the Quality of Protection is an important part of SLAs.
