Want to get started with System design interview preparation, start with these 👇 1. Learn to understand requirements 2. Learn the difference between horizontal and vertical scaling. 3. Study latency and throughput trade-offs and optimization techniques. 4. Understand the CAP Theorem (Consistency, Availability, Partition Tolerance). 5. Learn HTTP/HTTPS protocols, request-response lifecycle, and headers. 6. Understand DNS and how domain resolution works. 7. Study load balancers, their types (Layer 4 and Layer 7), and algorithms. 8. Learn about CDNs, their use cases, and caching strategies. 9. Understand SQL databases (ACID properties, normalization) and NoSQL types (key–value, document, graph). 10. Study caching tools (Redis, Memcached) and strategies (write-through, write-back, eviction policies). 11. Learn about blob storage systems like S3 or Google Cloud Storage. 12. Study sharding and horizontal partitioning of databases. 13. Understand replication (leader–follower, multi-leader) and consistency models. 14. Learn failover mechanisms like active-passive and active-active setups. 15. Study message queues like RabbitMQ, Kafka, and SQS. 16. Understand consensus algorithms such as Paxos and Raft. 17. Learn event-driven architectures, Pub/Sub models, and event sourcing. 18. Study distributed transactions (two-phase commit, sagas). 19. Learn rate-limiting techniques (token bucket, leaky bucket algorithms). 20. Study API design principles for REST, GraphQL, and gRPC. 21. Understand microservices architecture, communication, and trade-offs with monoliths. 22. Learn authentication and authorization methods (OAuth, JWT, SSO). 23. Study metrics collection tools like Prometheus or Datadog. 24. Understand logging systems (e.g., ELK stack) and tracing tools (OpenTelemetry, Jaeger). 25.Learn about encryption (data at rest and in transit) and rate-limiting for security. 26. And then practise the most commonly asked questions like URL shorteners, chat systems, ride-sharing apps, search engines, video streaming, and e-commerce websites Coding Interview Resources: https://whatsapp.com/channel/0029VammZijATRSlLxywEC3X
