#System Design Interview

System Design Interview: Google Maps Navigation microservice. Small sample of what a system design for a navigation service might look like. If you aren’t familiar with A*, check it out, really cool algorithm that for some reason they didn’t tech me in my algos / dsa class. #csmajors #systemdesign #coding #programming

Comment “sys” For A FULL GUIDE If you’re preparing for cloud or backend job interviews, these concepts show up again and again; not as theory, but as how you think at scale. From API design and rate limiting, to message queues that handle traffic spikes, and finally how microservices talk to each other without breaking everything, this is the backbone of modern systems. If you understand why these exist and when to use them, you’re already ahead of most candidates. What should I break down next in detail? Let me know in the comments! . .

Handling 1 Million RPS isn’t about code — it’s about smart architecture. 1️⃣ Traffic Distribution (Load Balancers) ➡️ Spreads incoming requests across many servers so nothing overloads. Example: 1M requests split across 200 servers = ~5K requests per server. ⸻ 2️⃣ Scale Out, Not Up (Horizontal Scaling) ➡️ Add more machines instead of making one server bigger. Example: Flash sale traffic? Instantly launch 50 new API instances. ⸻ 3️⃣ Fast Reads with Cache ➡️ Use Redis/Memcached to avoid hitting the database every time. Example: Cached user data = millions of DB calls saved daily. ⸻ 4️⃣ Edge Delivery with CDN ➡️ Static content loads from servers closest to the user. Example: Users in Delhi fetch images from a Delhi CDN node. ⸻ 5️⃣ Background Work with Queues ➡️ Heavy tasks run asynchronously so APIs respond instantly. Example: Payment succeeds now, email receipt sent in background. ⸻ 6️⃣ Split the Database (Sharding) ➡️ Divide data across multiple databases to handle scale. Example: Usernames A–M on one shard, N–Z on another. ⸻ 7️⃣ Rate Limiting ➡️ Prevent abuse and traffic spikes from taking the system down. Example: Limit clients to 100 requests/sec to block bots from killing the API. ⸻ 8️⃣ Lightweights Payloads ➡️ Smaller payloads = faster responses + less bandwidth. Example: Send only required fields instead of massive JSON blobs.

System Design: The Weather App Be careful when directly integrating with 3rd party APIs. They are very useful, but you have to treat them carefully. Consider rate limits, handling different responses (404, 429, 500), and caching when you can. #coding #programming #systemdesign #csmajors
