Building Scalable Microservices with Go and AWS In my experience working with fintech startups and enterprise applications, I’ve learned that building scalable microservices requires careful consideration of architecture, technology choices, and operational practices. Why Go for Microservices? Go has become my go-to language for microservices development for several key reasons: Performance: Go’s compiled nature and efficient goroutines provide excellent performance Concurrency: Built-in concurrency primitives make handling multiple requests effortless Simplicity: Clean syntax and minimal abstractions lead to maintainable code Fast Compilation: Quick build times accelerate the development cycle Architecture Patterns 1. Hexagonal Architecture I’ve found hexagonal architecture (ports and adapters) particularly effective for microservices. It helps maintain clean separation between business logic and external dependencies. ...

My Journey Learning Kubernetes When I first started working with Kubernetes, I was overwhelmed by the complexity. Today, I’m managing production clusters and even integrating KubeVirt for VM workloads. Here’s what I learned along the way. Starting Simple I began with: Minikube for local development Understanding Pods, Deployments, and Services Basic kubectl commands Key Concepts That Clicked 1. Declarative Configuration The “desired state” model was a paradigm shift: 1apiVersion: apps/v1 2kind: Deployment 3metadata: 4 name: my-app 5spec: 6 replicas: 3 7 selector: 8 matchLabels: 9 app: my-app 10 template: 11 metadata: 12 labels: 13 app: my-app 14 spec: 15 containers: 16 - name: app 17 image: my-app:latest 2. Everything is an API Object Understanding that everything in Kubernetes is just an API resource helped me grasp custom resources and operators. ...
