System Design Blog Collection
Welcome to my growing collection of System Design fundamentals. These posts are designed to make complex concepts easy to understand — perfect for interview prep, learning, or refreshing your knowledge.
😌 Design a High Performance Key-Value Store (System Design Interview Guide)
Easily Learn How to Create a Scalable, Low-Latency Storage Key-Value Store
This guide explores the design of a highly available and scalable distributed key-value store, covering essential techniques like consistent hashing for partitioning, vector clocks for conflict resolution, and quorum consensus for tunable consistency.
Part 2: Complete Your Understandings for Rate Limiter Design
Take a deep dive into designing a rate limiter
Complete your understandings of how to design a rate limiter and explore the depths and details of rate limiting.
Rate Limiting Made Easy: 5 Common Algorithms (Sliding Window Counter)
Learn the Sliding Window Counter Algorithm
Master the 5 essential rate-limiting algorithms, featuring the sliding window counter. The sliding window counter combines the fixed window counter and sliding window log and is one of the most commonly seen algorithms in large-scale production environments.
Rate Limiting Made Easy: 5 Common Algorithms (Sliding Window Log)
Learn the Sliding Window Log Algorithm
Master the 5 essential rate-limiting algorithms, featuring the sliding window log. The sliding window log uses a 60 second rolling look back window and requests per rolling window. It is very close to the fixed window counter, but removes the edge case problem.
Rate Limiting Made Easy: 5 Common Algorithms (Fixed Window Counter)
Learn the Fixed Window Counter Algorithm
Master the 5 essential rate-limiting algorithms, featuring the fixed window counter. The fixed window counter creates time blocks for a certain predetermined amount of time, and rate limits requests.
Rate Limiting Made Easy: 5 Common Algorithms (Leaking Bucket)
Learn the Leaking Bucket Algorithm
Master the 5 essential rate-limiting algorithms, featuring an in-depth breakdown of the Leaking Bucket strategy—a steady flow algorithm that uses a queue, behaving much like the token bucket.
Rate Limiting Made Easy: 5 Common Algorithms (Token Bucket)
Learn the Token Bucket Algorithm
Master the 5 essential rate-limiting algorithms, featuring an in-depth breakdown of the Token Bucket strategy—a coin-based system that ensures your API stays stable even under heavy traffic.
System Design was HARD until I Learned these 30 Concepts
30 Essential System Design Concepts Every Developer Should Know
In this article, I'll walk you through the 30 most important System Design concepts every developer should know.
Back-of-the-Envelope Calculations
How to Perform Back-of-the-Envelope Calculations
Learn how to estimate system capacity and performance using simple approximations — essential for system design interviews.
Caching in JavaScript Made Easy
A brief overview of what a cache is and what it looks like
Learn how to create a cache and what it is used for when optimizing systems. This is a fundamental concept you should know well for System Design Interviews.
Consistent Hashing
Consistent Hashing Made Easy
Understand consistent hashing rings, virtual nodes, and why it's critical for distributed systems like DynamoDB and Redis.
Rate Limiters
Rate Limiters Made Easy
Control request rates with token bucket, leaky bucket, sliding windows — prevent abuse and protect your APIs.
Load Balancers
Load Balancer Made EASY in Systems Design Interviews
Distribute traffic, handle failures, improve availability — the traffic cop of your backend servers.
Vertical vs Horizontal Scaling
Horizontal Vs Vertical Scaling Made EZ
Compare upgrading one machine vs adding more machines — tradeoffs, real-world hybrid approaches, and when to use each.
