Why Your First API Request is Painfully Slow (And How to Fix It!)

Ever wondered why that first API request to your serverless backend takes seconds to respond, while the next one finishes in milliseconds?

In this video, I break down Cold and Warm Starts using a practical, step-by-step lifecycle breakdown so you can understand serverless execution and optimize latency without getting lost in complex cloud jargon.

👇 KEY TAKEAWAYS & WHAT YOU'LL LEARN:
- 💡 What is a Cold Start and why does scaling to zero cause latency spikes?
- ⚡ The 4-step initialization sprint: provisioning infrastructure, loading code, booting runtimes, and app startup.
- 🛡️ How a Warm Start works by reusing existing containers to execute in milliseconds.
- ⏱️ Real-world triggers in production: idle timeouts, traffic spikes, and code deployments.
- 🚀 Comparison across runtimes: V8 isolates vs Go vs heavy JVM monoliths.
- 🛠️ 5 actionable strategies to mitigate cold starts, including native GraalVM binaries and provisioned concurrency.
