AWS is Amazon's cloud computing platform.
Regions are collections of resources in a geographic area. They're isolated and independent of one another, except where replication makes resources available across a boundary.
Regions introduced before 20th March 2019 are enabled by default, and cannot be disabled. Other regions can be enabled via the Console.
Quotas are hard limits beyond which an account can't provision additional resources. They're usually region-specific.
Some quotas can't be increased.
Resources can be tagged with metadata that can make them easier to locate, in key-value pairs AWS calls tags. Tags make it easier to manage, identify, organise, search for and filter resources.
Consider tagging by:
- Operating System
AWS resource groups allow grouping related resources into a structure for easier bulk operations.
Not all services support resource groups.
Amazon Resource Names uniquely identify resources. They're in the following format:
arn:partition:service:region:account-id:resource-id arn:partition:service:region:account-id:resource-type:resource-id arn:partition:service:region:account-id:resource-type/resource-id
And are comprised of:
partitiondescribes the group of regions in which the account exists:
aws- AWS consumer regions,
aws-cn- AWS China consumer regions.
aws-us-gov- AWS GovCloud regions.
service- identifies the service, e.g.
regioncontains the region name.
account-idcontains the owning AWS account ID.
resource-typedefine subtypes within a service; treat these as opaque.
resource-idis the resource-specific section of the identifier, and may contain a path.
resource-id is a path, wildcards (
*) can be used to match segments, but not subsegments.
AWS is broken up into a number of services, most with regional availability. AWS services are generally accessible via service endpoints of the form:
