Monolith vs Microservices: Understanding the Trade-Offs

Designing Fault Tolerance in Microservices Architecture

System Design: Building a Bulletproof Payment Gateway! 🚀 Basic payment setups fail during network timeouts. To block catastrophic duplicate charges, enforce client-generated idempotency keys (UUIDs). The server saves this key first; if a duplicate request arrives, it immediately returns the cached result instead of re-charging the buyer. Never overwrite database rows to update payment statuses. Instead, implement an immutable ledger where every state change—authorized, captured, or refunded—cre

What is Microservices Architecture 🤯 Guys! Microservices architecture is a system design where an application is split into many small, independent services that each handle a specific business capability. Each service runs independently, communicates through APIs, and can be developed or deployed without affecting the others. This allows teams to scale, update, and maintain parts of the system separately instead of managing one large codebase. In short, microservices break a big application in
