Building a Simple Web Server Using Golang
In this post, I will guide you through the process of building a simple web server using Go. Go, also known as Golang, is a statically typed, compiled progra...
Let's learn Go (GoLang) Programming Language
In this post, I will share some resources and tips for learning Go Lang. Go, also known as Golang, is a statically typed, compiled programming language desig...
Docker Images Version Tagging Best Practices
In this post, I will share some best practices for tagging Docker images. Proper versioning and tagging of Docker images are crucial for maintaining a clean ...
Feature Flags — Architecture & Rollout Strategy
Feature flags decouple deployment from release. They enable controlled rollout, rapid rollback, and experimentation. Advanced teams treat feature flags as a ...
Contract-First vs Code-First API Development
APIs are long-lived contracts between teams. The main decision is whether the contract is defined first (contract-first) or inferred from code (code-first). ...
Infrastructure Drift: Detection and Prevention
Infrastructure drift occurs when real-world resources diverge from the declared state in infrastructure-as-code (IaC). Drift erodes reliability, makes deploy...
Go Interfaces: Design Principles and Testability
Go interfaces are implicit — a type satisfies an interface by implementing its methods, without declaring it. This small design decision has large implicatio...
Go Context: Cancellation and Deadline Propagation
context.Context is Go's mechanism for propagating cancellation signals, deadlines, and request-scoped values across goroutine boundaries. Correct context usa...
Go Channels and Select: Advanced Patterns
Go channels are the primary mechanism for goroutine communication. Beyond basic send/receive, channels enable sophisticated coordination patterns: fan-out, f...
Disaster Recovery: RTO/RPO Practical Guide
Disaster recovery (DR) planning is effective only when RTO and RPO objectives are clearly defined and tested. RTO (Recovery Time Objective) sets the maximum ...
Monorepo vs Polyrepo in Large Systems
Repository strategy shapes build performance, developer workflow, and release governance. Large organizations must choose between monorepo and polyrepo based...
Data Consistency vs Performance Tradeoffs in Distributed Databases
Consistency is not a binary choice in distributed systems. You can often select stronger guarantees for critical operations and weaker guarantees for latency...
Lamport Clocks & Distributed Time
Time is a fundamental concept in distributed systems, but physical clocks are unreliable due to clock drift, network delays, and relativistic effects. Leslie...
Consistency Models Explained Simply
Consistency models describe how a distributed system presents updates to readers. Understanding these models helps you select the right datastore and set cor...
GitOps — Practical Implementation Guide
GitOps applies software engineering practices to infrastructure: Git is the source of truth, and automated controllers reconcile the desired state. A practic...
