Hi Guys,

I am new to the AWS EC2 service. When I launched one instance, it shows me to select a type of image that has CPU, ECU, etc. Can anyone explain these terms?

ECU means Amazon EC2 compute unit. Amazon EC2 uses a variety of measures to provide each instance with a consistent and predictable amount of CPU capacity. In order to make it easy for developers to compare CPU capacity between different instance types. The amount of CPU that is allocated to a particular instance is expressed in terms of these EC2 Compute Units. In the free tier account, Amazon will not charge anything for the t2.micro type.
