Welcome to the first edition of Bhuvnesh’s Newsletter! Every week, I’ll be sharing insights from my journey—whether it’s a new Software Architecture Lesson, a Software Architect’s Challenge, an interesting read, or key takeaways in software engineering and system design. Let’s dive in!
This Week’s Theme: Monolith or Microservices? Making the Right Call
"Microservices are the future." "Start small, go monolith." You've heard both sides—but which one is right? The answer, as always, is "it depends."
Microservices offer flexibility, scalability, and independent deployments, but they come with complexity—network calls, distributed data, and service orchestration challenges. Meanwhile, monolithic architectures are simple to develop and deploy, but they risk becoming unmanageable as systems grow.
The real key? Make the right call for your context. Start with monoliths when speed, simplicity, and rapid iteration matter. Move to microservices when scale, resilience, and modularity become critical. The transition should be an evolution, not a blind decision.
Software Architecture Lesson I Wrote
This week, I explored Microservices Design Principles and how to make them work effectively. The lesson covers:
??High Cohesion & Low Coupling – Keep services focused on single responsibilities while ensuring minimal dependencies.
?? Decentralized Data Management – Each microservice should own its data to improve scalability and reduce bottlenecks.
?? Design for Failure & Resilience – Implement circuit breakers, retries, and failover mechanisms to handle failures gracefully.
?? API-First Approach – Define clear interfaces so services can interact efficiently.
If you're designing microservices or considering a transition, this guide will help you avoid common pitfalls: ?? Read the full lesson

Software Architect’s Challenge
Challenge: Implementing Authentication in Microservices
Authentication in a microservices setup is tricky—centralized authentication? Service-to-service trust? JWTs, OAuth, or API Gateways? This challenge pushes you to design a robust authentication strategy that balances security and scalability.

Lessons & Insights
This week’s biggest takeaway: Technology choices should be guided by business needs, not hype. Whether you pick monoliths or microservices, trade-offs matter. The best engineers know when to optimize, simplify, or scale.
