Backend Architecture. API for Reliable Enterprise Applications

The book is dedicated to the complete cycle of backend development, starting from requirement gathering and ending with application monitoring. The main topics of the book concern scaling applications, load balancing, creating and refining REST APIs, selecting tools for data analysis, SQL and NoSQL technologies, ensuring application security, architectural styles used in backend design. It also addresses issues of testing and deploying applications, data exchange in synchronous and asynchronous modes, the difference between coupling and cohesion. Without a strict adherence to specific technologies, the main features and complexities that arise during the creation of new services are revealed, as well as recommendations for improving existing services and microservices. The structure of the book implies a comprehensive study of the material, revealing the principles of building backend solutions within real projects, where it is necessary to simultaneously consider the technological component, changing business requirements, and the human factor.
