In this video, we explore Production Architecture and the critical systems that keep large-scale applications running reliably in the real world. Designing a system is one thing, but operating it in production with millions of users requires a completely different set of tools and practices. We break down how modern companies build and operate production systems using microservices, service discovery, CI/CD pipelines, deployment strategies, monitoring systems, and reliability engineering principles. You’ll learn how engineers safely deploy new code using Blue-Green deployments and Canary deployments, how services dynamically find each other using service discovery, and how teams detect issues early with monitoring and alerting systems. We’ll also cover the key reliability concepts used by companies like Google, Netflix, and Amazon, including SLIs, SLOs, and SLAs, and how these metrics help teams maintain uptime and performance at scale. By the end of this video, you’ll understand how production systems are designed not just to work, but to stay reliable, observable, and resilient even under massive traffic. Topics Covered • Monolith vs Microservices • Service Discovery • CI/CD Pipelines • Blue-Green Deployments • Canary Deployments • Logging & Structured Logs • Metrics vs Logs vs Traces • Monitoring & Alerting • SLIs, SLOs, and SLAs This video is part of the System Design Fundamentals Series If you're learning system design for software engineering interviews or real-world backend architecture, this series will walk you through the essential building blocks step by step.
