Deployment
Once we design our application with the element of concurrency, it becomes easier to think and adapt to many concurrent services. The system becomes more flexible.
Once we design our application with the element of concurrency, it becomes easier to think and adapt to many concurrent services. The system becomes more flexible.
Architecting the system with independent services helps us to make our configurations dynamic. By planning for decoupling and concurrency, we can also have independent options where we can choose not to be concurrent.
But trying to add concurrency to a non-concurrent system is much more harder.
If we design to allow for concurrency, we can more easily meet scalability or performance requirements when the time comes—and if the time never comes, we still have the benefit of a cleaner design.
