Capacity Reservations in Wavelength Zones - Amazon Elastic Compute Cloud

Capacity Reservations in Wavelength Zones

AWS Wavelength enables developers to build applications that deliver ultra-low latencies to mobile devices and end users. Wavelength deploys standard AWS compute and storage services to the edge of telecommunication carriers' 5G networks. You can extend an Amazon Virtual Private Cloud (VPC) to one or more Wavelength Zones. You can then use AWS resources like Amazon EC2 instances to run applications that require ultra-low latency and a connection to AWS services in the Region. For more information, see AWS Wavelength Zones.

When you create On-Demand Capacity Reservations, you can choose the Wavelength Zone and you can launch instances into a Capacity Reservation in a Wavelength Zone by specifying the subnet associated with the Wavelength Zone. A Wavelength Zone is represented by an AWS Region code followed by an identifier that indicates the location, for example us-east-1-wl1-bos-wlz-1.

Wavelength Zones are not available in every Region. For information about the Regions that support Wavelength Zones, see Available Wavelength Zones in the AWS Wavelength Developer Guide.

Considerations

You can't use Capacity Reservation groups in a Wavelength Zone.

To use a Capacity Reservation in a Wavelength Zone

  1. Enable the Wavelength Zone for use in your AWS account. For more information, see Enable Wavelength Zones in the Amazon EC2 User Guide for Linux Instances.

  2. Create a Capacity Reservation in the Wavelength Zone. For Availability Zone, choose the Wavelength. The Wavelength is represented by an AWS Region code followed by an identifier that indicates the location, for example us-east-1-wl1-bos-wlz-1. For more information, see Create a Capacity Reservation.

  3. Create a subnet in the Wavelength Zone. For Availability Zone, choose the Wavelength Zone. For more information, see Creating a subnet in your VPC in the Amazon VPC User Guide.

  4. Launch an instance. For Subnet, choose the subnet in the Wavelength Zone (for example subnet-123abc | us-east-1-wl1-bos-wlz-1), and for Capacity Reservation, choose the specification (either open or target it by ID) that's required for the Capacity Reservation that you created in the Wavelength. For more information, see Launch instances into an existing Capacity Reservation.
