Akka

Akka is a powerful platform that simplifies building and operating highly responsive, resilient, and scalable services.

The platform consists of

the Akka SDK for straightforward, rapid development with AI assist and automatic clustering. Services built with the Akka SDK are automatically clustered and can be deployed on any infrastructure.
and Akka Automated Operations, a managed solution that handles everything for Akka SDK services from auto-elasticity to multi-region high availability running safely within your VPC.

The Akka SDK and Akka Automated Operations are built upon the foundational Akka libraries, providing the building blocks for distributed systems.

Akka has been downloaded more than 1 billion times and has powered thousands of systems for over 15 years. Akka enables millions of concurrent users, terabyte stream processing, low-latency read/write data access, 99.9999% availability, and multi-region high availability and disaster recovery (HA/DR).

Akka is used to build agentic AI, AI inference, transactional, analytical, digital twin, IOT, and edge-to-cloud systems. It is simple to learn and operate. Akka creates production-ready systems without requiring prior knowledge of events, threading, or distributed systems.
