Build powerful reactive, concurrent, and distributed applications more easily

Akka is a toolkit for building highly concurrent, distributed, and resilient message-driven applications for Java and Scala.

Akka Insights is intelligent monitoring and observability purpose built for Akka.

• 

  Simpler Concurrent & Distributed Systems

  Actors and Streams let you build systems that scale up, using the resources of a server more efficiently, and scale out, using multiple servers.

• 

  Resilient by Design

  Building on the principles of The Reactive Manifesto Akka allows you to write systems that self-heal and stay responsive in the face of failures.

• 

  High Performance

  Up to 50 million msg/sec on a single machine. Small memory footprint; ~2.5 million actors per GB of heap.

• 

  Elastic & Decentralized

  Distributed systems without single points of failure. Load balancing and adaptive routing across nodes. Event Sourcing and CQRS with Cluster Sharding. Distributed Data for eventual consistency using CRDTs.

• 

  Reactive Streaming Data

  Asynchronous non-blocking stream processing with backpressure. Fully async and streaming HTTP server and client provides a great platform for building microservices. Streaming integrations with Alpakka.

Akka is the implementation of the Actor Model on the JVM.
