A well-designed API does not just serve requests.
It controls them.
That control is called Rate Limiting.
Imagine a toll booth on a highway.
Cars can pass, but only at a safe rate.
Too many at once, and traffic collapses.
Same in systems:
Request arrives
API checks the quota
Quota exceeded → 429 Too Many Requests
Why engineers implement rate limiting:
• Prevent bots and brute-force attacks
• Protect backend services from spikes
• Keep the system fair for all users
• Avoid unexpected cloud bills
Common algorithms powering it:
Fixed Window
Sliding Window
Token Bucket
Leaky Bucket
Real-world scenario:
OTP or login endpoints usually allow
3 to 5 attempts per minute
Then temporarily block further requests.
Uncontrolled traffic → Outages
Controlled traffic → Reliable systems

"Caveman" prompting is a viral technique for Claude AI.
Write short. No filler words. No pleasantries.
Just direct instructions.
Goal: reduce tokens and cut costs.
Why it works:
LLMs read tokens, not sentences.
Long sentence → more tokens → higher cost
Short sentence → fewer tokens → lower cost
Example:
"I understand your request and will explain in detail"
vs
"Explain now"
Same meaning. Far fewer tokens.
Less tokens. More efficiency.
Longer conversations.

What is a Reverse Proxy?
Reverse Proxy - A server that sits in front of backend servers and forwards client requests to them, hiding internal servers, improving security, load balancing traffic, and enabling caching and SSL termination.
How it works:
User → Internet → Reverse Proxy → Application Servers
Real example:
When you open a website, Nginx or Cloudflare receives your request first, then forwards it to the correct backend server without exposing the server's real IP address.
Common uses:
-- Security - Hide backend servers
-- Performance - Cache responses
-- Load balancing - Distribute traffic
-- SSL termination - Handle HTTPS encryption
Tools:
-- Nginx
-- HAProxy
-- Cloudflare
-- Apache
Client talks to one server.
That server talks to many servers behind the scenes.
