System Architecture Foundations

Architecture is about:

  • firmitas (durability)
  • utilitas (utility)
  • venustas (beauty)
De Architectura

Purpose: Provides understanding of the core concepts in the discipline of software architecture, overview of different software architecture styles and how software architecture affects quality attributes of the software systems, what is the value of software architecture and the architecture decisions

Results: Skill to describe and evaluate the architecture of software systems, reason upon architectural decisions and organize the architecture work and governance

Subject matter: Overview of software architecture discipline, basic concepts related to the software and system architecture and architecture descriptions, overview of widely known software architecture styles and analysis of the main properties of these architecture styles, construction of an architecture style based on the example of REST, ways and tools for describing and documenting the architecture of software systems, quality attributes of software systems and the connection of software systems architecture to the quality attributes, evaluation of software systems architecture, value of software architecture and architecture decisions, context of software architecture – enterprise architecture


  1. History of and early views on architecture, design vs. architecture, software architecture discipline, concepts & terminology related to the systems architecture (ISO42010)
  2. Architectre style, classification of architecture styles, overview and analysis of main architecture styles (SISD/MISD/SIMD/MIMD, “boxology”, “mud-ball”, SOA, micro-services, containers, serverless, ...), derived architecture styles (C2, REST), constructing an architecture style (on example of REST)
  3. Documenting architectures, viewpoints and views, architecture description languages, architecture frameworks
  4. Software quality attributes, constructing architecture, analyzing and evaluating architectures (ATAM, CBAM, ARID), cost and value of architecture
  5. Larger context – systems-of-systems, enterprise architecture, sustainable architecture
  6. From one system to many – (industry) reference architectures, product line architectures, model-driven development
  7. Role of architect, architecture work, architecture governance, agile development and software architecture
  8. Architecture for cloud, architecture for AI and machine learning (neural networks), adaptive systems, ...
