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.
Akka is the implementation of the Actor Model on the JVM.
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.
Up to 50 million msg/sec on a single machine. Small memory footprint; ~2.5 million actors per GB of heap.
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.
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.
Lightbend changed the license on all Akka modules from Apache 2.0 to the BSL v1.1 (Business Source License) starting with Akka v2.7, which was released in October 2022.
“We have decided to change Akka’s license to ensure a healthy balance between all parties, shared responsibility, and, by extension, contribute to Akka’s future development,”
Lightbend is the company behind Akka, used by development teams to build the most demanding, globally distributed, cloud native application environments and streaming data pipelines.
