Presentation: Tweet"Keynote: Open Systems - Actors and Cloud"

As developers we all like to use tightly couple systems where possible and loosely coupled ones where necessary. In the closed world of the pre-Cloud era, traditional relational databases have gained tremendous leverage from tight coupling of B-tree storage, transaction managers, and query optimizers, providing developers with an efficient, consistent, and easy to use ACID programming model. In the open, distributed, asynchronous, and heterogeneous world of the Cloud, we must consider more loosely coupled computational models that are designed with distribution and concurrency in from the get go, and accept that our knowledge of the world is never fully consistent. Actors as envisioned by Carl Hewitt fit the bill perfectly. In this talk we will show how highly-available stateful Actors provide a flexible and easy to use programming model for the Cloud on the outside, while still allowing for the traditional programming models on the inside.
