Scaling REST API with actor systems

[wonderful world]

I have an OrderManager MicroService REST API end point. One of the method is retrieving the orders for a customer. Under heavy load (many requests from the HTML Client application) I want to scale the OrderManager.

Is the best practice is to have the OrderManager MicroService developed with clusters behind it, and increase the customers? In this case, there is no need to scale the MicroService. Or should it be the MicroService deployed to multiple nodes to scale?

Hi Varghese,

there was a talk by Michael Nash in Scala Days 2015 San Francsico and Amsterdam about scaling services with Akka. He mainly talks about Event Sourcing, CQRS and Cluster Sharding. In my opinion he really does a great job at presenting architecture of a scalable app using Akka. There is also an Activator template to get started with.

If you haven't seen it, I highly suggest watching it. Recording from Scala Days 2015 SF is available here.
