# Software Architecture

Designing systems at scale: microservices, API design, domain-driven design, and performance.

## Available Subjects

### API Design

API design is the process of planning and architectural modeling of application programming interfaces. You will understand how to create secure, scalable, and intuitive RESTful or GraphQL endpoints that facilitate seamless communication between software systems.

**Difficulty:** Beginner, Intermediate, Advanced

**Resources:** 1 books, 2 websites

[Learn API Design](/subject/api-design)

### Domain-Driven Design

Domain-driven design is an architectural approach that aligns software development with complex business domains. You will understand how to model software systems using bounded contexts, entities, and value objects to solve complex business problems.

**Difficulty:** Beginner, Intermediate, Advanced

**Resources:** 3 books, 4 websites

### Enterprise Architecture

Enterprise architecture is the practice of aligning an organization's business strategy with its IT infrastructure and software systems. You will understand how to design, analyze, and govern large-scale systems to support long-term business goals.

**Difficulty:** Beginner, Intermediate, Advanced

**Resources:** 2 books, 3 websites

### GraphQL & REST APIs

REST and GraphQL are the two main ways web clients talk to servers. You will learn resource design, schemas, queries and mutations, versioning, authentication and when each style fits.

**Difficulty:** Beginner, Intermediate, Advanced

**Resources:** 2 books, 3 websites, 1 papers

### Microservices

Microservices is an architectural style that structures an application as a collection of loosely coupled, deployable services. You will understand how to design, deploy, and manage distributed systems that improve scalability and fault tolerance.

**Difficulty:** Beginner, Intermediate, Advanced

**Resources:** 3 books, 2 websites

[Learn Microservices](/subject/microservices)

### Performance Engineering

Performance engineering is the practice of ensuring software systems meet speed, scalability, and resource utilization requirements. You will understand how to profile applications, identify bottlenecks, optimize code, and conduct load testing under heavy traffic.

**Difficulty:** Beginner, Intermediate, Advanced

**Resources:** 1 books, 1 courses, 1 websites

[Learn Performance Engineering](/subject/performance-engineering)

### Product Management

Product management is the organizational function that guides every step of a product’s lifecycle, from development to positioning and pricing. Learners will understand how to define product vision, gather user requirements, collaborate with engineering teams, and launch successful products.

**Difficulty:** Beginner, Intermediate, Advanced

**Resources:** 4 books

### Scalability

Scalability is the capacity of a system to handle growing amounts of work or traffic by expanding its resources. You will understand how to design architectures that scale horizontally and vertically using load balancing, caching, and database sharding.

**Difficulty:** Beginner, Intermediate, Advanced

**Resources:** 2 books, 2 courses, 1 websites

[Learn Scalability](/subject/scalability)

### Software Design Patterns

Software design patterns are reusable, standardized solutions to commonly occurring problems in software design. You will understand how to implement creational, structural, and behavioral patterns to write flexible, maintainable, and decoupled code.

**Difficulty:** Beginner, Intermediate, Advanced

**Resources:** 3 books, 1 courses, 1 websites

[Learn Software Design Patterns](/subject/software-design-patterns)

### Software Documentation

Software documentation is the practice of writing clear guides, API references, and system diagrams for developers and users. You will understand how to explain technical concepts, document codebases, and maintain accessible, up-to-date technical resources.

**Difficulty:** Beginner, Intermediate, Advanced

**Resources:** 2 books, 4 websites

[Learn Software Documentation](/subject/software-documentation)

### Software Testing

Software testing is the process of evaluating an application to verify that it functions correctly and meets requirements. You will understand how to write unit, integration, and end-to-end tests to ensure code reliability and prevent regressions.

**Difficulty:** Beginner, Intermediate, Advanced

**Resources:** 4 books, 1 websites

[Learn Software Testing](/subject/software-architecture-software-testing)

### System Design

System design is the process of defining the architecture, modules, interfaces, and data for a system to satisfy specified requirements. You will understand how to design scalable, reliable, and maintainable distributed systems from the ground up.

**Difficulty:** Beginner, Intermediate, Advanced

**Resources:** 1 books, 2 websites
