Distributed Coordination: Locks, Leader Election & Idempotency

Distributed Systems & Scalability, System Design /

In distributed systems, multiple services run independently and communicate over unreliable networks.Coordinating actions across these services is challenging but essential for correctness and consistency. In this blog, we’ll explore distributed locks, leader election, and idempotency—three foundational coordination concepts. Why Coordination Is Hard Distributed systems face: Without coordination, systems may: Distributed Locks A distributed lock ensures […]

Fault Tolerance, Failover & High Availability

Distributed Systems & Scalability, System Design /

Failures are inevitable in distributed systems.Servers crash, networks fail, and data centers go down. Good system design focuses not on preventing failures, but on handling them gracefully. In this blog, we’ll cover fault tolerance, failover, and high availability, and how modern systems stay reliable at scale. Understanding Failures in Distributed Systems Common types of failures

Event-Driven Architecture & Messaging

Distributed Systems & Scalability, System Design /

As systems grow and move toward microservices, direct synchronous communication becomes a bottleneck.Event-driven architecture (EDA) helps systems scale by allowing services to communicate asynchronously using events and messages. In this blog, we’ll cover event-driven architecture, message queues vs event streams, and when to use each. Synchronous vs Asynchronous Communication Synchronous Communication Example:Service A calls Service

Microservices vs Monolith

Distributed Systems & Scalability, System Design /

Choosing the right architecture is one of the most important decisions in system design.Two common approaches are monolithic architecture and microservices architecture. Each has its strengths, weaknesses, and ideal use cases. In this blog, we’ll clearly compare monoliths vs microservices, explain trade-offs, and help you decide when to use each. What Is a Monolithic Architecture?
