What will we talk about?

• Monolitic Architecture
• Service Oriented Architecture (SOA)
• Microservices Architecture

Monolitic Architecture

Monolithic architecture means that a software application is in "one piece". This means that all the code, functions and components are gathered in the same place. In a way, that application is like a "giant block"; you can find everything in it.

For many developers, monolithic architecture offers simplicity and less initial complexity. Working on a single codebase can streamline the development process and get you started quickly. Also, having all the functionality together can help you understand more clearly how the application works as a whole.

However, the monolithic architecture also has some disadvantages. Especially in large projects, the code base can become complex and difficult to maintain over time. Also, a change in one section can affect other sections and cause bugs.

Service Oriented Architecture (SOA)

Service Oriented Architecture (SOA), as an approach to software development, divides applications into a set of independent services. These services represent specific functionalities and can communicate with each other. For example, a payment service, a user management service or an e-mail sending service.

The beauty of SOA is the independence of these services. That is, changing or updating one service does not affect the others. Each service performs its own task and can cooperate with another service.

Another beauty is that these services can be easily integrated across different systems. For example, an e-commerce application can integrate the payment service into the banking system and the user management service into the authentication system.

SOA provides flexibility and reusability. That is, you can use the same service in another application or business process. This speeds up the development process and avoids code duplication.

In conclusion, SOA is a powerful architectural approach that promotes modularity and collaboration in software development.

Microservices Architecture

Microservice architecture is an approach that divides an application into many small parts, with each part having a specific functionality. An application is divided into small services that perform many different tasks. For example, user management, payment processing, sending emails, etc. These services are developed and run independently.

Microservices function by talking to each other. For example, the user management service can make a call to the payment service to inform it that a user has made a payment. Each service has its own database and code base, making them independent.

This approach makes large and complex systems easier to manage. Changing or updating one service does not affect the others. Also, the fact that each service is the responsibility of a separate team ensures rapid development and better focus.

Microservices break down different parts of the application, making the development process and maintenance of the application easier. This helps to develop more flexible and scalable applications.
