Akka is a JVM-based platform built on the actor model for building concurrent, distributed, and resilient applications, comprising core libraries, an SDK, and managed operations. Alpakka extends Akka Streams with reactive, backpressure-aware connectors to systems like Kafka, Cassandra, AWS, and AMQP.

Use cases

• build highly concurrent and scalable services without locks
• build clustered fault-tolerant distributed systems
• stream data with backpressure from Kafka or AWS services
• build reactive event-driven microservices
• process terabyte-scale data streams
• build IoT and edge-to-cloud systems
• implement self-healing high-availability services

When to choose

• you need high-throughput, low-latency concurrent processing on the JVM
• you want actor-model abstractions for distributed state and messaging
• you need reactive stream integrations with external systems via Alpakka
• you require clustering, elasticity, and multi-region HA

When to avoid

• you want a simple CRUD web app with minimal complexity
• your team has no appetite for the actor-model learning curve
• you need a permissive open-source license (Akka uses a BSL license)
• you are outside the JVM ecosystem
