Overview

A Partition is a group of AWS Region and Service objects. You can use a partition to determine what services are available in a region, or what regions a service is available in.

Partitions

AWS accounts are scoped to a single partition. You can get a partition by name. Valid partition names include:

  • "aws" - Public AWS partition
  • "aws-cn" - AWS China
  • "aws-us-gov" - AWS GovCloud

To get a partition by name:

aws = Aws::Partitions.partition('aws')

You can also enumerate all partitions:

Aws::Partitions.each do |partition|
  puts partition.name
end

Regions

A Partition is divided up into one or more regions. For example, the "aws" partition contains, "us-east-1", "us-west-1", etc. You can get a region by name. Calling Partition#region will return an instance of Region.

region = Aws::Partitions.partition('aws').region('us-west-2')
region.name
#=> "us-west-2"

You can also enumerate all regions within a partition:

Aws::Partitions.partition('aws').regions.each do |region|
  puts region.name
end

Each Region object has a name, description and a list of services available to that region:

us_west_2 = Aws::Partitions.partition('aws').region('us-west-2')

us_west_2.name #=> "us-west-2"
us_west_2.description #=> "US West (Oregon)"
us_west_2.partition_name "aws"
us_west_2.services #=> #<Set: {"APIGateway", "AutoScaling", ... }

To know if a service is available within a region, you can call #include? on the set of service names:

region.services.include?('DynamoDB') #=> true/false

The service name should be the service's module name as used by the AWS SDK for Ruby. To find the complete list of supported service names, see Partition#services.

Its also possible to enumerate every service for every region in every partition.

Aws::Partitions.partitions.each do |partition|
  partition.regions.each do |region|
    region.services.each do |service_name|
      puts "#{partition.name} -> #{region.name} -> #{service_name}"
    end
  end
end

Services

A Partition has a list of services available. You can get a single Service by name:

Aws::Partitions.partition('aws').service('DynamoDB')

You can also enumerate all services in a partition:

Aws::Partitions.partition('aws').services.each do |service|
  puts service.name
end

Each Service object has a name, and information about regions that service is available in.

service.name #=> "DynamoDB"
service.partition_name #=> "aws"
service.regions #=> #<Set: {"us-east-1", "us-west-1", ... }

Some services have multiple regions, and others have a single partition wide region. For example, IAM has a single region in the "aws" partition. The Service#regionalized? method indicates when this is the case.

iam = Aws::Partitions.partition('aws').service('IAM')

iam.regionalized? #=> false
service.partition_region #=> "aws-global"

Its also possible to enumerate every region for every service in every partition.

Aws::Partitions.partitions.each do |partition|
  partition.services.each do |service|
    service.regions.each do |region_name|
      puts "#{partition.name} -> #{region_name} -> #{service.name}"
    end
  end
end

Service Names

Service names are those used by the the AWS SDK for Ruby. They correspond to the service's module.

.partition(name) ⇒ Partition

Return the partition with the given name. A partition describes the services and regions available in that partition.

aws = Aws::Partitions.partition('aws')

puts "Regions available in the aws partition:\n"
aws.regions.each do |region|
  puts region.name
end

puts "Services available in the aws partition:\n"
aws.services.each do |services|
  puts services.name
end

Parameters:

  • name (String)

    The name of the partition to return. Valid names include "aws", "aws-cn", and "aws-us-gov".

Returns:

Raises:

  • (ArgumentError)

    Raises an ArgumentError if a partition is not found with the given name. The error message contains a list of valid partition names.

def partition(name)
  default_partition_list.partition(name)
end

.partitionsEnumerable<Partition>

Returns an array with every partitions. A partition describes the services and regions available in that partition.

Aws::Partitions.partitions.each do |partition|

  puts "Regions available in #{partition.name}:\n"
  partition.regions.each do |region|
    puts region.name
  end

  puts "Services available in #{partition.name}:\n"
  partition.services.each do |service|
    puts service.name
  end
end

Returns:

  • (Enumerable<Partition>)

    Returns an enumerable of all known partitions.

.service_idsHash<String,String>

Returns a map of service module names to their id as used in the endpoints.json document.

Returns:

  • (Hash<String,String>)

    Returns a map of service module names to their id as used in the endpoints.json document.
