Executive Summary

• Cornell AWS accounts using Direct Connect will be migrated to a new network architecture in January 2023.
• This new architecture simplifies Direct Connect configuration and management, and improves Direct Connect bandwidth and flexibility.
• The migration process is designed to avoid interruption of Direct Connect connectivity, how brief interruptions may occur. 
• Cornell AWS account owners/administrators will be solicited for feedback directly via email several times throughout this process. But, in most cases, this input is not required for the migration to proceed.
  • AWS accounts having VPCs using Direct Connect and with numerous subnets and route tables, or where network resources are configured by infrastructure-as-code will need to provide input to complete this migration.
• While line items for charges to Cornell AWS accounts will change between the old and new Direct Connect architectures, the overall change in cost is negligible.
  • CIT will be paying for new costs of ~$36/mo for each customer VPC connected the new Direct Connect architecture.
