Hands-On Microservices with Rust

Actors in microservices

To develop a microservice using actors, you should split your service into tasks that solves different kinds of work. For example, you can use a separate actor for every incoming connection or database interaction, and even as a supervisor to control other actors. Every actor is an asynchronous task that is executed in a reactor.

The benefits of this approach are as follows:

• It's simpler to write separate actors than a bulk of functions
• Actors can fail and respawn
• You can reuse actors

One important benefit of using actors is reliability, because every actor can be failed and respawned, so you don't need a long recovery code to handle failures. It doesn't mean your code can call the panic! macro everywhere, but this ...
