Akka is using the Actors together with STM to create a unified runtime and programming model for scaling both UP (multi-core) and OUT (grid/cloud). Akka provides location transparency by abstracting away both these tangents of scalability by turning them into an ops task. This gives the Akka runtime freedom to do adaptive automatic load-balancing, cluster rebalancing, replication & partitioning
The Go programming language was designed to make programming productive and efficient. Go is a concurrent language that compiles quickly to machine code yet has the convenience of garbage collection and the power of run-time reflection. This talk is an introduction to Go that focuses on how the design of the language helps it achieves those goals.
