# Networking cost inefficiencies | Cloud Efficiency Hub Canonical: https://www.pointfive.co/efficiency-hub/service-category/networking 59 documented networking cost inefficiencies across GCP, AWS, Azure and more, each with detection steps and remediation. ## All inefficiencies Each entry explains the waste, the billing model behind it, how to detect it and how to fix it. / 59 inefficiencies - GCP Cloud NAT CER-0331 ### [Excessive Data Processing Fees on High-Throughput Cloud NAT Gateways](https://www.pointfive.co/efficiency-hub/inefficiencies/excessive-data-processing-fees-on-high-throughput-cloud-nat-gateways) Cloud NAT charges a per-GiB data processing fee on all traffic routed through the gateway - both inbound responses and outbound requests. For high-throughput workloads such as web crawlers, data pipelines, container image pulls, and... Networking - AWS NAT Gateway CER-0325 ### [Excessive NAT Gateway Data Processing Charges from Unoptimized Traffic Routing](https://www.pointfive.co/efficiency-hub/inefficiencies/excessive-nat-gateway-data-processing-charges-from-unoptimized-traffic-routing) NAT Gateway charges a per-gigabyte data processing fee on all traffic that passes through it - in either direction - regardless of whether the destination is the public internet or another AWS service in the same region. This per-GB charge... Networking - Azure NAT Gateway CER-0319 ### [Idle Azure NAT Gateway Attached to Subnet Without Active Workloads](https://www.pointfive.co/efficiency-hub/inefficiencies/idle-azure-nat-gateway-attached-to-subnet-without-active-workloads) Azure NAT Gateways are commonly deployed to provide outbound internet connectivity for resources within virtual network subnets. Over time, the workloads that originally required this outbound access may be scaled down, migrated, or... Networking - Azure Private Link CER-0318 ### [Orphaned Private Endpoints After Target Service Deletion](https://www.pointfive.co/efficiency-hub/inefficiencies/orphaned-private-endpoints-after-target-service-deletion) Azure Private Endpoints are network interfaces that provide private connectivity from a virtual network to Azure PaaS services such as Storage Accounts, SQL Databases, or Key Vaults. When the target service behind a private endpoint is... Networking - Azure Firewall CER-0313 ### [Azure Firewall Premium SKU Deployed Without Using Premium Features](https://www.pointfive.co/efficiency-hub/inefficiencies/azure-firewall-premium-sku-deployed-without-using-premium-features) Azure Firewall is available in three SKUs - Basic, Standard, and Premium - each designed for different security requirements and priced accordingly. The Premium SKU includes advanced threat protection capabilities such as TLS inspection,... Networking - Azure Bastion CER-0312 ### [Idle or Underutilized Azure Bastion Deployment](https://www.pointfive.co/efficiency-hub/inefficiencies/idle-or-underutilized-azure-bastion-deployment) Azure Bastion incurs continuous hourly charges from the moment it is deployed until the resource is deleted - regardless of whether any connections are actively being made. This means a Bastion host sitting idle in a development or test... Networking - Azure Load Balancer CER-0292 ### [Idle Azure Load Balancers in Non-Production Environments](https://www.pointfive.co/efficiency-hub/inefficiencies/idle-azure-lb-in-non-prod-env) Azure Load Balancers remain provisioned after the backend workloads they supported have been scaled down, stopped, or decommissioned. This is common in non-production environments where virtual machines are shut down outside business... Networking - Azure Virtual WAN CER-0300 ### [Overprovisioned Azure Virtual WAN Hub Capacity](https://www.pointfive.co/efficiency-hub/inefficiencies/overprovisioned-azure-virtual-wan-hub-capacity-a123) An Azure Virtual WAN hub is provisioned with more capacity than required to support real network traffic. Because hub costs scale with the number of configured scale units, overprovisioned hubs continue to incur higher charges even when... Networking - Azure Data Factory V2 CER-0261 ### [Suboptimal Integration Runtime Region Selection in Azure Data Factory](https://www.pointfive.co/efficiency-hub/inefficiencies/suboptimal-integration-runtime-region-selection-in-azure-data-factory-0bcad) When Integration Runtimes use the default "Auto Resolve" region setting, the work does not always run in the region where the data lives. For copy activities, Azure makes a best effort to run in the sink data store's region (or the closest... Networking - Azure Load Balancer CER-0223 ### [Suboptimal Load Balancer Rule Configuration in Azure Standard Load Balancer](https://www.pointfive.co/efficiency-hub/inefficiencies/suboptimal-load-balancer-rule-configuration-in-azure-standard-load-balancer) As organizations migrate from the Basic to the Standard tier of Azure Load Balancer (driven by Microsoft's retirement of the Basic tier), they may unknowingly inherit cost structures they didn't previously face. Specifically, each load... Networking - GCP Cloud NAT CER-0174 ### [Idle Cloud NAT Gateway Without Active Traffic](https://www.pointfive.co/efficiency-hub/inefficiencies/idle-cloud-nat-gateway-without-active-traffic) Each Cloud NAT gateway provisioned in GCP incurs hourly charges for each external IP address attached, regardless of whether traffic is flowing through the gateway. In many environments, NAT configurations are created for temporary access... Networking - GCP Load Balancers CER-0202 ### [Idle Load Balancer](https://www.pointfive.co/efficiency-hub/inefficiencies/idle-load-balancer) Provisioned load balancers continue to generate costs even when they are no longer serving meaningful traffic. This often occurs when applications are decommissioned, testing infrastructure is left behind, or backend services are removed... Networking Showing 12 of 59 --- Source: the public page above.
