As we know, change is eternal. Humans always look for better solutions. This is how microservices became what it is today and it will evolve further in the future. Today, organizations are using agile methodologies to develop applications—it is a fast-paced development environment that has grown to a much larger scale after the invention of the cloud and distributed technologies. Many argue that monolithic architectures could also serve a similar purpose and be aligned with agile methodologies, but microservices still provide a better solution to many aspects of production-ready applications.

To understand the design differences between monolithic and microservices architectures, let's take an example of a restaurant table-booking application. This application may have many services to do with customers, bookings, analytics, and so on, as well as regular components, such as presentation and databases.

We'll explore three different designs here: the traditional monolithic design, the monolithic design with services, and the microservices design.
