Differences between a reverse proxy, a load balancer, and an API gateway.
Feature Reverse Proxy Load Balancer API Gateway Main purpose A hotel’s concierge handles guest requests. Distributes incoming network traffic across multiple servers. Provides a single entry point for API requests to microservices. Core task Routes requests to the appropriate backend. Distributes traffic to prevent server overload. Manages requests and responses between a client and microservices.…

Service-Oriented Architecture (SOA) v/s Microservices Architecture
The difference between Service-Oriented Architecture (SOA) and Microservices Architecture lies mainly in granularity, design philosophy, technology stack, and deployment strategy. 🔑 High-Level Summary: Feature SOA (Service-Oriented Architecture) Microservices Architecture Granularity Coarse-grained (larger services) Fine-grained (smaller, focused services) Communication Often uses Enterprise Service Bus (ESB) Lightweight protocols like HTTP/REST, gRPC Technology Stack Tends to be more…

Software Design Principles and Architectural Strategies
1. DRY (Don’t Repeat Yourself) 2. KISS (Keep It Simple, Stupid) 3. YAGNI (You Aren’t Gonna Need It) 4. SoC (Separation of Concerns) 5. SOLID Principles 6. Dependency Rule 7. Scaling 📈 🔹 Vertical Scaling (Scale-Up) Definition: Increase resources (CPU, RAM, Disk) on a single server. 🔹 Horizontal Scaling (Scale-Out) Definition: Add more machines to…

Different types of Software Architecture Patterns Overview
1. Monolithic 2. N-Layer / N-Tier 3. Clean Architecture 4. Modular Monolithic 5. Headless Architecture 6. Microservices Comparison Table Architecture Description Advantages Disadvantages Use Cases Monolithic Single unified application with tightly coupled components. Simple to develop and deploy. Hard to scale, tightly coupled, difficult to maintain. Small applications or early-stage products. N-Layer / N-Tier Logical…

Observability
Observability is a key requirement for monitoring and debugging microservice architectures. With the rise of distributed systems and the increasing complexity of modern software applications, observability has become an essential component of any production system. Observability in microservices involves the ability to gather and analyze data from each individual microservice to provide a comprehensive view…
