Data Transfer Pricing
ELI5 — The Vibe Check
Data transfer pricing is how cloud providers charge you for moving data in and out. Data IN is usually free (they want your data!). Data OUT costs money (they want to keep it!). It's like a Hotel California pricing model — checking in is free, but checking out costs you. This is why egress fees make CFOs cry.
Real Talk
Cloud data transfer pricing covers the cost of moving data between cloud services, regions, availability zones, and the internet. Ingress is typically free, while egress (data leaving the cloud) is charged per GB. Cross-region and cross-AZ transfers also incur costs. Understanding data transfer pricing is critical for cloud cost optimization.
