Roadmap for learning High-Level Design (HLD)

Here is a complete roadmap for learning High-Level Design (HLD):

➤ 𝗙𝘂𝗻𝗱𝗮𝗺𝗲𝗻𝘁𝗮𝗹 𝗖𝗼𝗻𝗰𝗲𝗽𝘁𝘀:

  1. System Design Basics:

    • Understanding client-server models, database basics, and CAP theorem
    • Load Balancing, Caching, Proxies, and CDNs
  2. Scalability and Reliability:

    • Scaling techniques (vertical vs. horizontal)
    • Fault tolerance, redundancy, and availability considerations
  3. Data Partitioning and Sharding:

    • Partitioning methods and handling data consistency across shards

➤ 𝗔𝗱𝘃𝗮𝗻𝗰𝗲𝗱 𝗖𝗼𝗺𝗽𝗼𝗻𝗲𝗻𝘁𝘀:

  1. Database Selection:

    • Choosing between SQL and NoSQL based on use cases
    • Database replication and consistency models
  2. Caching Strategies:

    • Cache-aside, read-through, and write-through
    • Eviction policies and caching tiers
  3. Messaging and Queueing Systems:

    • Message brokers (e.g., Kafka, RabbitMQ) and event-driven architecture
    • Asynchronous communication, pub-sub models, and real-time data processing

➤ 𝗗𝗶𝘀𝘁𝗿𝗶𝗯𝘂𝘁𝗲𝗱 𝗦𝘆𝘀𝘁𝗲𝗺 𝗣𝗮𝘁𝘁𝗲𝗿𝗻𝘀:

  1. Microservices Architecture:

    • Service decomposition, inter-service communication, and service discovery
    • API Gateway and circuit breaker patterns
  2. Event-Driven Architecture:

    • Event sourcing, CQRS, and handling eventual consistency
  3. Data Consistency and Transactions:

    • Distributed transactions, two-phase commit, and BASE vs. ACID principles

➤ 𝗗𝗶𝗮𝗴𝗿𝗮𝗺𝘀 𝗮𝗻𝗱 𝗣𝗿𝗮𝗰𝘁𝗶𝗰𝗲:

  1. Component Diagram:

    • Breakdown of services and their interactions
  2. Sequence and Interaction Diagrams:

    • Capturing how different services or users interact across systems
  3. Practice Real-World Scenarios:

    • Design a URL Shortener, Social Media Feed, Chat Application, File Storage, etc.
