In the previous blog posts, we designed and implemented a distributed system comprising User Service (users) and Order Service (ordered) with observability using OpenTelemetry, Jaeger, Prometheus, and Alertmanager. In this final part, we'll deploy th...
Introduction In Part 5, we implemented the tracing in userd & orderd services. In a distributed system, tracing helps follow a request's journey across services, while metrics play a crucial role in observability by providing visibility into system b...
Introduction In Part 4, we implemented the orderd service. In a distributed system, tracking what happens across multiple services is crucial. Logging provides insights into what occurred, while tracing helps follow a request's journey across service...
Introduction In Part 3 we implemented user service. In this post, we will implement an Order Service using Golang, gRPC, PostgreSQL, and GORM. Note: We are using static price here for product passed in create order request and we will be connecting ...
In Part 2 we introduced apis for User service, this post walks through implementing a User Service in Go using gRPC with PostgreSQL as the database. The service provides user authentication with JWT-based authentication. The implementation includes: ...
In Part 1, we set up our project structure. Now, we’ll: ✅ Define User and Order APIs ✅ Generate gRPC code from .proto files. We have created apis folder so lets navigate to that folder and define our apis there. cd ecom-grpc/apis Note: Please repla...
Introduction & Project Overview 🚀 Why Build a Distributed System with Go & gRPC? Modern applications need to be scalable, fast, and efficient. A monolithic approach may work initially, but as your app grows, it becomes hard to maintain. This is wher...
In today's fast-paced technological landscape, businesses need scalable and flexible solutions to adapt quickly to changing demands. This is where microservices architecture shines compared to the traditional monolithic approach. 1. What is Monolithi...
