3 Clouds are interesting, but programming for clouds...? Writing software for clouds is challenging because... Cloud systems are inherently parallel and distributed, High availability is financially crucial, and many other historical problems like security, reliability, elasticity, and etc. Vrije University of Amsterdam Orleans 3

8 Grains What are Grains? Grains are the basic programming units in Orleans. They don t share memory or any other transient state with each other. They are single threaded. process each request before handling the next one. interact entirely through asynchronous message passing. Vrije University of Amsterdam Orleans 5

19 Activation What are activations? Grains are logical programming abstractions and Activations are run-time execution units. Orleans run-time system, automatically creates multiple activations of a busy grain. Activations process independent requests for the grain, possibly across multiple servers.
