DRHCCOST05-BP01 Monitor data transfer to and from your hybrid edge workload

Regularly track and analyze data transfer costs.

Desired outcome: You monitor the costs associated with data transfer.

Benefits of establishing this best practice: You can recognize the cost associated with your network flows.

Level of risk exposed if this best practice is not established: Medium

Implementation guidance

While using hybrid edge services like AWS Outposts and Local Zones, monitor data transfer patterns and costs, and design your network configurations with cost optimization in mind. Data transfer from Outposts to AWS Regions is free, but transfers from Regions to Outposts are more expensive over the internet compared to AWS Direct Connect. Local Zones have internet gateways for local egress, but routing traffic to AWS Regions incurs additional charges similar to inter-AZ transfers. You can use local VPC peering for Outposts and Local Zones, which incurs lower costs than using AWS Transit Gateway and minimizes network overhead. Additionally, you should design hybrid architectures following networking best practices to meet low latency requirements while optimizing costs.
