A blog site on our Real life experiences with various phases of DevOps starting from VCS, Build & Release, CI/CD, Cloud, Monitoring, Containerization.
Running a growing e-commerce platform like Opszilla is thrilling. You’re processing thousands of orders daily across the US and Canada, scaling infrastructure, and expanding into new markets. But amidst all that momentum, something starts to break: your data infrastructure and database performance.
At first, it’s subtle—slower queries, lagging reports, a few scaling hiccups. Then the real issue surfaces: you’re still running on MySQL 5.7, a version nearing its end-of-life in October 2023.
Last December, a single DNS misconfiguration at a major streaming platform caused a global outage that cost $23 million in lost revenue and affected 180 million users during the World Cup final. The root cause? Their legacy DNS server couldn’t handle the traffic spike, taking 47 minutes to resolve the issue.
Meanwhile, their competitor running CoreDNS experienced the same traffic surge but stayed online, gaining 2.3 million new subscribers that day.
This isn’t just another “infrastructure matters” story. This is about the invisible foundation of the internet that separates digital empires from digital disasters.

“Your code doesn’t just ship — it survives a gauntlet of digital Darwinism where only the fittest features reach users.”
Last month, two digits in a database version number brought at a Fortune 500 company a production outage that cost $4.7 million in lost revenue. The root cause? Their staging environment was running on PostgreSQL 13 while production was on PostgreSQL 15. A simple version mismatch became a career-ending incident.
This isn’t just another “environments matter” story. This is about the invisible architecture of trust that separates unicorn startups from digital graveyards.

Your smart thermostat senses a temperature drop before you notice. Your camera recognizes a familiar face the second it appears. And none of it goes through the cloud. That’s the power of Edge AI with TensorFlow, where machine learning runs locally on IoT devices, making them faster, more private, and incredibly efficient.
In this blog, we’ll explore how TensorFlow Lite models are optimized for edge hardware, the challenges of deploying lightweight AI models on embedded systems, and the benefits of real-time AI inference at the edge for smart devices.
