Eventually, we looked at how the choice of a particular way of storing data may affect both the application design and the performance of our system. Indeed, in modern architecture, we may want to pick the right storage solution for each use case by choosing different solutions where needed.
In the next chapter, we are going to discuss some architectural cross-cutting concerns. Topics such as security, resilience, usability, and observability are crucial to successful application architecture and will be analyzed to see their impacts and best...
