Foundations of IT Systems Architecture

Building reliable and scalable IT infrastructure starts with a deep understanding of how individual components work together as a cohesive whole. This text-based course introduces you to the strategic role of the systems architect and the fundamental principles of modern design. You will transition from a basic technical perspective to a broad architectural mindset, learning to evaluate complex systems through the lens of performance, security, and scalability. What you'll learn: - Understand the distinct roles and career paths of systems and solutions architects - Apply systems thinking to decompose complex environments into manageable components - Identify the core interactions between software, hardware, and network layers - Evaluate modern architectural patterns including microservices and cloud-native design - Master the terminology used to define system requirements and constraints - Practice conceptualizing system layouts through detailed written exercises The curriculum begins with essential terminology and the evolution of architecture before exploring modern methodologies and cross-functional requirements. You will work through written explanations and scenarios that build your ability to think like an architect. This course is created for beginners and those looking to transition into architectural roles, requiring no previous experience in the field.
