In a monolithic architecture, we'd have a single piece of software that would handle the customers, their orders, the database connections, the website, the inventory, and any other tasks needed for the online store to be successful.
A single piece of software doing everything might seem like an inefficient approach for software design, which is the case in some scenarios. However, it is important to mention that monolithic applications are not always bad. There are some scenarios where a single software service doing all the work is an acceptable idea. This includes minimum viable products or MVPs where we try to build something fast to get it out for test users to try. It also includes use cases where not a lot of data load or traffic is expected, such as an online store for legacy board...
