HNCOST05-BP01 Forecast demand and baseline requirements before scaling dedicated connections

Begin with IPSec VPN or small-scale dedicated connection links during testing or migration phases. Monitor traffic patterns to establish baseline bandwidth needs. Scale to larger dedicated connections or LAGs only after validating requirements.

Desired outcome: Cost-efficient scaling that matches actual workload demands, avoiding premature investment in underutilized dedicated connections.

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

Benefits of establishing this best practice:

  • Reduces upfront capital expenditure

  • Prevents over-provisioning of high-cost dedicated links

  • Enables data-driven scaling decisions

Implementation guidance

  • Analyze historical data transfer costs using services such as Cost Explorer or Cost and Usage

  • Analyze traffic patterns using services such as VPC Flow Logs or Transit Gateway Flog Logs
