EC2 compute unit
(ECU)
An AWS standard for compute CPU and memory. You can use this measure to evaluate the CPU capacity of different EC2 instance types.
EC2 instance
A compute instance in the Amazon EC2 service. Other AWS services use the term EC2 instance to distinguish these instances from other types of instances they support.
ECR

Elastic IP address
A fixed (static) IP address that you have allocated in Amazon EC2 or Amazon VPC and then attached to an instance. Elastic IP addresses are associated with your account, not a specific instance. They are elastic because you can easily allocate, attach, detach, and free them as your needs change. Unlike traditional static IP addresses, Elastic IP addresses allow you to mask instance or Availability Zone failures by rapidly remapping your public IP addresses to another instance.
Elastic Load Balancing
A web service that improves an application’s availability by distributing incoming traffic between two or more EC2 instances.

elastic network interface
An additional network interface that can be attached to an instance. Elastic network interfaces include a primary private IP address, one or more secondary private IP addresses, an elastic IP address (optional), a MAC address, membership in specified security groups, a description, and a source/destination check flag. You can create an elastic network interface, attach it to an instance, detach it from an instance, and attach it to another instance.
Elasticsearch
An open source, real-time distributed search and analytics engine used for full-text search, structured search, and analytics. Elasticsearch was developed by the Elastic company.
