How is Akka.NET Used?

Akka.NET can be used in-process or inside large, distributed real-time systems; we support a wide variety of use cases.

Akka.NET can be used to solve the following types of problems:

Concurrency - Akka.NET actors only process messages one-at-a-time and they do so in first in, first out (FIFO) order; this means that any application state internal to an actor is automatically thread-safe without having to use locks or any other shared-memory synchronization mechanisms.
Stream Processing - Akka.NET actors and Akka.Streams make it easy to build streaming applications, used for processing incoming streams of data or incoming streams of live events such as UI or network events inside native applications.
Event-Driven Programming - actors make it easy to build event-driven applications, as actors' message-processing routines naturally express these types of designs.
Event Sourcing and CQRS - Akka.Persistence, used by actors to make their state re-entrant and recoverable across restarts or migrations between nodes, natively supports event sourcing. Akka.Persistence.Query can be used to compute CQRS-style projections and materialized views from Akka.Persistence data.
Location Transparency - Akka.Remote makes it simple for actors in remote processes to transparently communicate with each other.
Highly Available, Fault-Tolerant Distributed Systems - Akka.Cluster, Akka.Cluster.Sharding, and other tools built on top of Akka.Cluster make it possible to build highly available and fault-tolerant distributed systems by leveraging peer-to-peer programming models with topology-aware message routing and distribution.
Low Latency, High Throughput - Akka.NET aims to be low latency and high throughput, processing 10s millions of messages per second in-memory and hundreds of thousands of messages per second over remote connections.

Akka.NET v1.5.0-alpha3 is a security patch for Akka.NET v1.5.0-alpha2 but also includes some other fixes.
Security Advisory**: Akka.NET v1.5.0-alpha2 and earlier depend on an old System.Configuration.ConfigurationManager version 4.7.0 which transitively depends on System.Common.Drawing v4.7.0. The System.Common.Drawing v4.7.0 is affected by a remote code execution vulnerability [GHSA-ghhp-997w-qr28](https://github.com/advisories/GHSA-ghhp-997w-qr28).
We have separately created a security advisory for [Akka.NET Versions < 1.4.46 and < 1.5.0-alpha3 to track this issue](https://github.com/akkadotnet/akka.net/security/advisories/GHSA-gpv5-rp6w-58r8).
