Introduction To Lagom

With James Roper (14 Min)

Services are asynchronous. Intra-service communication is managed for you. Streaming is out of the box. Your microservices are resilient by nature.


Developer Setup

With Mirco Dotta (11 Min)

Development is familiar. Use your favorite IDE and favorite dependency injection tools. You leverage the old to build something new.


Managing Data Persistence

With Patrik Nordwall (16 Min)

Systems are distributed. Akka Cluster and Akka Persistence are under the hood. Cluster sharding is implicit. CQRS and event sourcing is made trivially easy. Your systems are cloud ready and elastic.

Lagom ConductR Deployment

With Christopher Hunt (13 Min)

Deployment is seamless. Your services are already set up for production. With one command, you safely scale out in production.
