Network Cost Savings

AWS Network VPC​

  • Amazon VPC Endpoints to securely access AWS services without the need for public IP addresses, NAT gateways, or VPN connections.
  • VPC peering to connect VPCs in the same or different AWS accounts and avoid the need for additional VPN connections or internet gateways.
  • NAT gateways with Elastic IPs to enable instances in a private subnet to access the internet.
  • AWS Transit Gateway to simplify VPC network management, and reduce the number of VPN connections, internet gateways, and NAT gateways.
  • VPC flow logs to monitor network traffic, identify security threats, and optimize network performance..
  • VPC security groups and network ACLs to secure your VPC.
  • AWS PrivateLink to securely access services from your VPC.
  • VPC endpoints for S3 to securely access S3 from your VPC.
  • AWS Resource Access Manager to share VPC resources across multiple AWS accounts.
  • AWS cost allocation tags.

Metrics that can be improved:​

  • Data transfer costs
    • Data transfer costs between VPCs, regions, and the internet.
  • Instance utilization
    • Instance utilization metrics like CPU and network usage.
  • Network bandwidth utilization
    • Monitor the network bandwidth utilization metrics and optimize the network bandwidth allocation based on the changing workload demands, enabling you to avoid over-provisioning and unnecessary bandwidth costs.
  • VPC peering traffic
    • Monitor the VPC peering traffic and optimize the traffic routing to reduce the data transfer costs associated with cross-VPC traffic.
  • NAT gateway utilization
    • Monitor the NAT gateway utilization metrics and optimize the NAT gateway allocation based on the changing workload demands, enabling you to avoid over-provisioning and unnecessary NAT gateway costs.
