How Elastic Network Interfaces (ENI) Really Work in AWS | Deep Dive Explained

Welcome back to another AWS deep-dive explainer! 🚀
Have you ever wondered how an EC2 instance in AWS gets its identity?
How it receives a stable IP address, connects to other services, or how failover happens in seconds without downtime?

The answer lies in one powerful networking component: Elastic Network Interfaces (ENIs).

In this video, we break down everything you need to know about ENIs—from the basics to advanced real-world patterns used by cloud architects at scale.

🧠 What You’ll Learn in This Video

✔ What an Elastic Network Interface (ENI) actually is
✔ How ENIs connect an EC2 instance to a VPC/subnet
✔ Primary vs Secondary Private IPs
✔ Public IP vs Elastic IP (EIP) – key differences
✔ IPv6 support and how it works with ENIs
✔ Attaching & detaching ENIs for high availability and fast failover
✔ Multi-ENI architecture for advanced security and traffic isolation
✔ Real-world use cases including multi-homed servers & microservices design

🌟 Key Takeaways

🔹 ENIs are the fundamental unit of network identity in AWS
🔹 They enable high availability, scalability, and resilience
🔹 You can detach and reattach ENIs between servers within seconds
🔹 Perfect for load balancing, failover, microservices, firewalls & multi-network designs
