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.
