Akka

Akka is a software toolkit that helps developers build scalable, responsive, and resilient applications by managing many tasks simultaneously. It does this through "actors," which are like tiny, independent units of work that communicate by message passing. This approach allows applications to handle multiple operations at once without getting overwhelmed or crashing, even under heavy load. Akka simplifies the process of developing distributed systems—software that runs across multiple computers—by efficiently managing communication, fault tolerance, and concurrency. Essentially, it enables building complex, high-performance software that is easier to develop, maintain, and scale.
