What literary sources on information system architecture do you recommend for study?

For studying the architecture of information systems, I recommend the following books and resources:

• "Software Architecture in Practice" (Len Bass, Paul Clements, Rick Kazman) — a classic on software architecture, covering fundamental principles and patterns.
• "Clean Architecture" (Robert C. Martin) — explains how to build flexible and maintainable architectures.
• "Designing Data-Intensive Applications" (Martin Kleppmann) — a deep dive into the architecture of systems working with large volumes of data.
• "Patterns of Enterprise Application Architecture" (Martin Fowler) — a set of templates for building enterprise applications.
• Online courses on platforms like Coursera, edX, Udemy on software architecture and systems.

These sources will help understand both theoretical foundations and practical approaches to designing information systems.
