Understanding Service-Oriented Architecture (SOA)

Service-Oriented Architecture (SOA) involves breaking down processes or functions in a monolithic application into separate services that can handle requests independently. For example, in the context of sending emails from an app, breaking out the email sending process into a separate service removes it from the main CPU cycle, preventing delays in other requests. Implementing a queue, like using Redis or Rescue in Rails, allows for quick, efficient processing of requests by different workers or CPUs on separate threads, enhancing overall system performance.
