AWS Went Down. Here’s 𝐓𝐡𝐞 𝐄𝐧𝐠𝐢𝐧𝐞𝐞𝐫𝐢𝐧𝐠 𝐒𝐭𝐨𝐫𝐲 Nobody Told You | Tamil

In this video, I break down the recent AWS outage from a system design perspective — in simple language every student can understand.
You’ll learn what actually happened inside AWS, how DNS Planner and DNS Enactor work, why DynamoDB was involved, what a race condition is, and how AWS fixed it.

We’ll also talk about why even multi-region apps failed, what “velocity control” means, and how AWS avoids this kind of disaster in the future.
By the end, you’ll understand not just the outage — but the engineering lessons behind it.
