COST08-BP03: Implement services to reduce data transfer charges

Leverage AWS services specifically designed to reduce data transfer costs, such as CloudFront, Direct Connect, VPC endpoints, and regional optimization services. Strategic use of these services can significantly reduce data transfer expenses while improving performance.

Implementation guidance

AWS provides numerous services specifically designed to reduce data transfer costs while maintaining or improving performance. These services work by optimizing data paths, reducing internet egress, enabling private connectivity, and providing more cost-effective alternatives to traditional data transfer methods.

Cost Reduction Services

Content Delivery Networks: CloudFront provides global content delivery with reduced data transfer costs compared to direct internet egress from AWS regions.

Private Connectivity: Direct Connect and VPC endpoints eliminate internet gateway costs and provide more predictable pricing for high-volume transfers.

Regional Services: Services like S3 Transfer Acceleration and Global Accelerator optimize data transfer paths and reduce costs through AWS’s global network.

VPC Optimization: VPC endpoints, NAT Gateway optimization, and private subnets reduce unnecessary internet gateway usage and associated costs.

Service Categories

Edge Services: CloudFront, Global Accelerator, and edge computing services that bring content and processing closer to users.

Network Services: Direct Connect, VPN, and private connectivity services that provide cost-effective alternatives to internet-based transfers.

Storage Services: S3 Transfer Acceleration, Cross-Region Replication optimization, and intelligent tiering services.

Compute Services: Regional compute placement, edge computing, and serverless services that reduce data movement requirements.

AWS Services to Consider

Amazon CloudFront

Global CDN that significantly reduces data transfer costs by caching content at edge locations worldwide. Use CloudFront to reduce origin server load and internet egress costs.

AWS Direct Connect

Dedicated network connection that provides predictable, lower-cost data transfer for high-volume workloads. Use Direct Connect for consistent, high-bandwidth requirements.

VPC Endpoints

Private connections to AWS services that eliminate internet gateway data transfer costs. Use VPC endpoints to reduce costs for service-to-service communication.

AWS Global Accelerator

Improve application performance and reduce data transfer costs by routing traffic through AWS global network infrastructure.

Amazon S3 Transfer Acceleration

Accelerate uploads to S3 using CloudFront edge locations, reducing transfer time and potentially costs for large file uploads.

AWS PrivateLink

Secure, private connectivity between VPCs and AWS services without traversing the internet, reducing data transfer costs and improving security.
