System Design Fundamentals

System design skills separate senior engineers from junior ones. Understanding how to architect scalable, reliable systems is essential for software engineering careers and technical interviews at major tech companies.

Start with system design fundamentals—the core concepts every engineer needs. Then dive deeper into specific patterns and trade-offs that drive real-world architecture decisions.

Essential System Design Topics

Core concepts: scalability, reliability, consistency, and availability trade-offs

Distribute traffic effectively: round-robin, weighted, geographic routing

Cache patterns: Redis, CDNs, application-level caching, cache invalidation

CAP theorem, consensus algorithms, eventual consistency, partition tolerance

Sharding, replication, read replicas, and distributed database patterns

Async processing: RabbitMQ, Apache Kafka, event sourcing patterns

DevOps & Infrastructure

Modern software development requires understanding DevOps practices and cloud infrastructure. Whether you're pursuing cybersecurity or building web applications, knowing containerization, CI/CD, and infrastructure as code is essential.

Start with Docker containerization and CI/CD pipeline design, then explore cloud platforms and orchestration tools.

DevOps & Infrastructure Guides

Container fundamentals: Dockerfile best practices, multi-stage builds, security

K8s essentials: pods, services, deployments, and developer workflows

Automated testing, deployment strategies, pipeline security, and monitoring

Terraform vs Pulumi: declarative infrastructure, state management, modules

Cloud platform comparison: services, pricing, strengths, and use cases

Branching strategies: GitFlow, GitHub Flow, trunk-based development

Programming Languages & Technology Choices

Choosing the right programming language impacts project success, team productivity, and career opportunities. Whether you're studying computer science or transitioning careers, understanding language trade-offs helps you make informed decisions.

Our language guides compare performance, ecosystem, job market, and use cases to help you choose wisely. Start with choosing your first programming language if you're beginning your journey.
