Key Takeaways
- •Elastic IPs provide fixed public IPv4 addresses but should be avoided in favor of DNS or load balancers
- •Placement Groups control instance placement: Cluster for low latency, Spread for high availability, Partition for distributed systems
- •Elastic Network Interfaces (ENI) can be moved between instances for failover scenarios
- •EC2 Hibernate preserves RAM state for faster boot times, useful for long-running processes
