Many microservice frameworks available today require developers to manually run scripts in order to start their services, or add an automated infrastructure. Lagom realized the need for developers to be able to utilize the tools they were used to, such as hot code reloads —Without having to install a new toolset locally in order to test an application. Lagom allows for developers to manage hundreds of services from a command line. From there, users are able to perform testing, update services via hot code fixes, and more.
Powering the Pieces
Lagom relies on a number of additional technologies, including the Lightbend’s own Play Framework, Akka, Akka Streams, Akka Clustering and ConductR for resilience and auto-scaling. By utilizing Netty, REST and WebSockets for communication with applications or devices that require access to its services, Lagom assures high performance. Finally, Lagom utilizes Cassandra as its persistence store.
Lightbend Reactive Platform Fast Data Architecture
For those looking to get a head start working with Lagom, be aware that the production release isn’t available until early March 2016. That being said, companies can check out Lightbend’s Reactive Platform to decompose any of their existing monolith applications into microservices, or to create new microservices.
“What we observed was that while many of these companies had unlimited engineering resources and talent, the far greater pool of Java developers needed a more opinionated framework — specifically for Java — that enabled the construction of microservices built to run and scale on the JVM,” said Hayes. It is this which stands as the reason Lightbend opted to start out by first creating a Java API for Lagom, followed by a Scala API.
With the full release of Lagom, the Java community may have a powerful new tool in its arsenal for creating, managing, and scaling microservices to meet the rigorous demands of today’s applications.
