🔔 What’s New?
AWS just announced SnapStart support for Java 21 in AWS Lambda!
This means faster cold starts for your serverless Java apps — using the latest long-term support version.

💡 Why It Matters
Java apps often struggle with slow cold starts in Lambda. SnapStart mitigates this by pre-initializing your function, snapshotting the memory and execution state, and restoring it in milliseconds when invoked.

✅ Real-World Example: High-Performance APIs
If you're running a Java-based API on Lambda that needs to be highly responsive — this is a game-changer.

📌 Key Benefits
⚡ Up to 10x faster cold starts for Java functions
🧊 Works seamlessly with Spring Boot, Quarkus, Micronaut
☁️ Keep your infrastructure serverless without compromising performance
🔒 Java 21 means better performance, better security, and long-term support

🧠 Ideal For

Microservices in Java

Event-driven architectures

High-frequency serverless APIs
