Overview

This tutorial, unlike other tutorials which focus on specific vendors, is a multi-vendor comparison of regions.

TODO: Provide an interactive comparison.

I want you to feel confident that you’ve mastered this skill. That’s why this takes a hands-on approach where you type in commands and we explain the responses and possible troubleshooting. This is a “deep dive” because all details are presented.

Like a good music DJ, I’ve carefully arranged the presentation of concepts into a sequence for easy learning, so you don’t have to spend as much time as me making sense of the flood of material around this subject.

Sentences that begin with PROTIP are a high point of this website to point out wisdom and advice from experience. NOTE point out observations that many miss. Search for them if you only want “TL;DR” (Too Long Didn’t Read) highlights.

Stuck? Contact me and I or one of my friends will help you.

Definitions

Each region is a separate geographic area.


Amazon regions

  1. Open the Amazon EC2 console at
    https://console.aws.amazon.com/ec2

    Sign-in if you haven’t done so.

  2. Select your default region: from the navigation bar, view the options in the region selector.

    Code Name
    us-east-1 US East (N. Virginia)
    us-west-1 US West (N. California)
    us-west-2 US West (Oregon)
    eu-west-1 EU (Ireland)
    eu-central-1 EU (Frankfurt)
    ap-northeast-1 Asia Pacific (Tokyo)
    ap-northeast-2 Asia Pacific (Seoul)
    ap-southeast-1 Asia Pacific (Singapore)  
    ap-southeast-2 Asia Pacific (Sydney)
    sa-east-1 South America (São Paulo)

    Names in parentheses is what is displayed at the upper-right on various AWS consoles.

    NOTE: In addition to the above, Amazon’s has a AWS GovCloud (US) and China (Beijing) which cannot be specified this way.

  3. Availability Zones under each region are listed on the Status by service under each continent at status.aws.amazon.com

    Each region within Amazon contains multiple, isolated Availability Zones.

    Additional end-point locations via AWS CloudFormation CDN service.

    CAUTION: The number and mapping of Availability Zones per region may vary between AWS accounts.

    NOTE: Amazon charges for network traffic between availability zones.

    Set Default Region and URL for CLI

  4. Open your MacOS profile using a text editor (substitute atom with subl, vim, etc.):

    PROTIP: Set an environment variable to your default regional endpoint (for example, https://ec2.us-west-1.amazonaws.com):

    
    atom ~/.bash_profile
    
  5. Add to the bottom of the file based on your selection in the step above:

    export AWS_DEFAULT_REGION=us-west-2
    export EC2_URL=https://us-west-2.console.aws.amazon.com/ec2/v2/home?region=us-west-2

    Notice the region is specified twice in EC2_URL.

    WARNING: Do not include in EC2_URL the # and what follows, such as “#Instances:sort=instanceId”.

  6. Save the file and run the file to load it into memory:

    
    source ~/.bash_profile
    

    List regions using CLI

  7. In a Terminal window, view the very latest list of AWS regions:

    
     aws ec2 describe-regions
     aws ec2 describe-availability-zones --region us-west-2
     

    For examples of AWS CLI commands such as the above, see:
    Amazon’s User Guide on Regions and availability zones.

  8. If you get an error message like this:

    -bash: aws: command not found
    

    then install Python 2.7, pip, and the AWS CLI.

  9. If you get an error message such as this:

    An error occurred (UnauthorizedOperation) when calling the DescribeRegions operation: You are not authorized to perform this operation.
    

    then use the AWS configure command to obtain:

    • AWS Access Key ID
    • AWS Secret Access Key
    • Default region name (such as “us-west-2”)

    PROTIP: Create Named Profiles in file ~/.aws/credentials and ~/.aws/config (containing region) because you will likely use multiple AWS accounts.

    Then, go to IAM to define permissions for each user to access EC2.
