Digital Infrastructure Basics
A plain-language map of computing, storage, networks, identity, applications, data and operations.
Learning collection
Architecture & Foundations
Understand requirements, boundaries, components and trade-offs before selecting technology.
Technology Requirements and Constraints
Turn business needs, user needs and operating limits into testable technology requirements.
System Context and Boundaries
Define what belongs inside a system, what remains external and where responsibilities change.
How to Compare Technology Systems
Use a repeatable method to compare platforms, architectures and services without letting feature lists decide the outcome.
Technology Architecture Diagrams Explained
Choose useful context, container, component, deployment and data-flow diagrams without creating decoration.
Monoliths, Modular Systems and Microservices
Compare delivery and operating trade-offs before splitting a system into independently deployed services.
Client–Server and Distributed Systems
Understand how clients, servers, services and shared state interact across a network.
Service-Oriented Architecture
Use service boundaries and contracts to coordinate capabilities across multiple applications.
Event-Driven Architecture
Design systems around events, producers, consumers and asynchronous processing.
Edge Computing
Place processing closer to devices or users when latency, bandwidth, autonomy or privacy justify it.
Technical Debt and System Modernization
Identify deliberate shortcuts, hidden maintenance costs and practical modernization paths.
