🧩 Distributed Systems & Microservices Practice

This repository contains my hands-on practice with various Distributed System Components, Microservices Architecture, and Service Communication Tools.
Each folder demonstrates a specific concept or tool used in modern backend development — from service discovery and load balancing to messaging and API design.

🚀 Overview

This project collection showcases implementations of essential microservices technologies and tools.
Each demo focuses on one area — helping to understand how distributed systems work together efficiently, reliably, and at scale.

---

🧠 Modules Included

🧾 rest_demo

Basic REST API service built using FastAPI, implementing CRUD operations and modular structure.
Focus: REST fundamentals, routing, and response modeling.

---

⚙️ grpc_request_demo

Exploration of gRPC for high-performance, low-latency communication between services.
Focus: Protocol Buffers, gRPC server & client setup.

---

🔄 kafka_demo

Integration with Apache Kafka for real-time message streaming between producers and consumers.
Focus: Asynchronous communication and event-driven design.

---

🧭 consul_demo

Implementation of HashiCorp Consul for service discovery and health checks.
Focus: Dynamic service registration and discovery in microservice environments.

---

⚖️ load_balancing_concul

Demonstrates load balancing using Consul + Nginx, ensuring traffic is evenly distributed among instances.

---

🪶 rabitmq_demo

Showcases RabbitMQ for reliable message queuing between microservices.
Focus: Producer-consumer model and asynchronous task handling.

---

🧱 etcd_demo

Experiment with etcd, a distributed key-value store used for configuration and coordination in microservices.
Focus: Leader election and service registry.

---

📊 Monitoring (Prometheus Integration)

Prometheus is used for metrics collection and monitoring across services.
Each microservice exposes /metrics endpoints to allow Prometheus to scrape data such as:

• Request count
• Latency and error rates
• Response times

This setup can be visualized using Grafana for creating rich dashboards.
