System Design Interview Tips
Share this post with your friends!
1. Implement WebRTC to facilitate direct video calls.
2. Use database indexing to make database queries faster.
3. Apply consistent hashing to manage server loads efficiently.
4. Implement read-through caching to optimize read operations.
5. Implement rate limiters to control traffic flow and manage load.
6. Use inverted indexes for efficient text searches in large databases.
7. Choose NoSQL databases for managing unstructured data effectively.
8. Utilize WebSockets to enable real-time peer-to-peer communication.
9. Use checksum algorithms to ensure data integrity across different systems.
10. Deploy Content Delivery Networks (CDN) to speed up global content delivery.
11. Implement RDBMS to ensure transaction integrity and support ACID properties.
12. Set up disaster recovery data centers to mitigate risks of single points of failure.
13. Prefer horizontal scaling for NoSQL and use sharding for RDBMS to scale databases.
14. Incorporate load balancers to enhance system availability and manage performance.
15. Adopt eventual consistency to balance availability with consistency where necessary.
16. Use CDNs, load balancers, and caching to reduce response times and achieve low latency.
17. Add write-through caching with a master-slave architecture to build fault-tolerant systems.
18. Use asynchronous processing and message queues like Kafka for handling heavy write loads.
19. Use Least Recently Used (LRU) caching or explore other suitable cache eviction policies based on specific needs.

The brain is not wired to multitask.
Quit trying to win a prize for being busy and doing 2 or 3 things at once.
Dedicate yourself to each project properly, complete it, and then move on to the next
Put "❤️" if you found this post useful!
