Data egress, or the cost of sending data out of a cloud provider’s network to the public internet, is often overlooked when considering the overall cost of using cloud services. I have compiled a list of egress pricing for major cloud providers to help shed light on these costs. It’s important to note that these cost estimates are based on assumptions and may change over time. Cloud providers charge for egress because it costs them money to send data out of their network, and it may also be used to discourage certain types of usage. To keep egress costs down, consider using a Content Delivery Network (CDN), compressing data, utilizing data transfer pools, monitoring usage, and leveraging private networking if available. Understanding data egress is crucial to avoid unexpected expenses.
