AWS EC2 instance types

Security group:

• All inbound traffic is blocked by default
• All outbound traffic is authorized by default

NOTE:

• one Placement group is only for a single AZ

• out-of-the-box metrics for EC2 – the disk ( read/writes ), CPU Utilization, network (high level) for memory utilization, etc, custom metrics need to be set up

• The EC2 instance launched from the oldest launch configuration will be terminated first in ASG

Get EC2’s enhanced network capabilities through Elastic Network Adapter ( ENA ). Elastic Fabric Adapter ( EFA ) is similar to ENA with OS bypass functionality. In the Windows instance, only ENA is supported. If you attach EFA, it will act as ENA.
