For this migration, we are tagging AWS resources to provide information about how the each resource is involved in the migration itself, the v1 architecture, and the v2 architecture.
Tag Key | Tag Values | Description | VPC | Subnets | Route Tables | Transit Gateway | Virtual Private | Direct Connect Virtual Interfaces |
---|---|---|---|---|---|---|---|---|
cit:dc-arch-migration-target | yes/no/guidance-required | Will this resource itself be affected as part of the migration? For subnets, if "guidance-required" then account owners will be consulted. | ||||||
cit:dc-arch-migration-description | prose | Description of planned changes to this resource | ||||||
cit:dc-arch-version | v1/v2 | Is this a v1 or v2 architecture resource? After migration, v1 resources utilized in the v2 architecture will be relabeled as v2 resources. | ||||||
cit:dc-arch-migration-new-resource | yes/no | Is this a new resource specifically created for the v2 architecture? | n/a | n/a | n/a | n/a | ||
cit:dc-arch-migration-replaces | resource ID | If this v2 resource will be replacing a v1 resource, this ID references the resource that will be replaced. | n/a | n/a | n/a | n/a | n/a | |
cit:subnet-type | public/private | Is this a private or public subnet? Public subnets are those with a route to an Internet Gateway. Private subnets are all subnets that are not public. | n/a | n/a | n/a | n/a | n/a | |
cit:tgw-attachment-target | yes/no/guidance-required | Will a Transit Gateway be attached to this subnet? If "guidance-required" then account owners will be consulted about the TGW Attachments. | n/a | n/a | n/a | n/a | n/a | |
cit:tgw-attachment-guidance | tbd/attach/no-attach | This tag provides a place for a human reviewer to provide guidance about whether a TGW attachment should be made to the tagged subnet.
Of all these tags, this is the only tag whose value should be updated by customers. | n/a | n/a | n/a | n/a | n/a | |
cit:dc-vgw | yes/no | Does this Route Table contain rules referencing a VGW? | n/a | n/a | n/a | n/a | n/a |
Direct Connect Gateways are also involved in the migration but cannot be tagged.
