Ingress is traffic entering a network or cloud account, and egress is traffic leaving it. On public clouds, only egress carries a meaningful price. Evaluated November 2026, list prices as checked August 2026: serving 100 TB a month straight from an AWS region costs about $7,800 in internet egress at list rates (our estimate). The same 100 TB delivered through a volume-priced CDN costs $415 to $1,000. Amazon Web Services, Microsoft Azure and Google Cloud do not charge for ingress from the internet, but they bill internet egress per GB. AWS lists about $0.09 per GB for the first 10 TB each month in 2026, roughly $90 per TB. That asymmetry is why data transfer costs, not compute, dominate the bill for video, software and game delivery workloads. The verdict by workload depends mostly on volume: - **Under about 46 TB a month:** a flat plan (Amazon CloudFront Business, Cloudflare Pro) usually wins. - **Above 100 TB of cacheable video, installers, patches or images:** a per-TB CDN in front of your cloud origin cuts the egress line by roughly 80 to 95 percent. - **East-west traffic (inter-AZ, NAT, cross-region):** fix the architecture first, because no CDN touches that part of the bill. ## **What counts as ingress vs egress on a cloud bill** On a cloud invoice, ingress is any byte arriving into your account from the internet or another provider, and it is almost always billed at $0. Egress is any byte leaving a billing boundary: to the internet, to another region, across availability zones, or through a managed gateway. Each boundary has its own rate, and some paths are billed in both directions. | Traffic path | Direction | Typical AWS list charge (2026) | | --- | --- | --- | | Internet into EC2 or S3 | Ingress | $0 | | EC2 or S3 out to the internet | Egress | About $0.09 per GB for the first 10 TB, tapering to about $0.05 above 150 TB | | Between availability zones, same region | Both | $0.01 per GB in each direction | | Between regions | Egress from source | Typically $0.01 to $0.02 per GB | | Through a NAT Gateway | Both | $0.045 per GB processing, plus any transfer charge | | S3 or EC2 origin to Amazon CloudFront | Egress | $0 | | Cloud origin to a third-party CDN | Egress | Billed as internet egress | The only egress path that is free by default is the one into the provider's own CDN, and every other path out of the region is metered. Microsoft Azure and Google Cloud list comparable first-tier internet egress rates, roughly $0.08 to $0.12 per GB depending on tier and destination. A naming collision is worth flagging: a Kubernetes Ingress resource and the ingress or egress rules in a NetworkPolicy describe routing and filtering direction, not billing. A cluster can be ingress-heavy in Kubernetes terms while generating mostly egress on the invoice. ## **Why cloud providers charge egress fees but not ingress** Clouds charge egress fees because outbound traffic is where their transit and peering costs sit, and because free ingress with paid egress creates data gravity. Moving data in costs nothing, while moving it out (to users, another cloud or a cheaper CDN) costs about $90 per TB at first-tier list rates. Pricing on that path follows strategy more than cost. The gap between price and cost is visible in the market itself. High-volume CDNs publish delivery rates between $2.50 and $10 per TB at 100 TB a month, so cloud first-tier egress is priced at 9 to 36 times what specialist delivery networks charge for the same bytes. Since 2024, AWS, Google Cloud and Azure have waived egress for customers moving data out entirely, prompted in part by the EU Data Act. That waiver covers exits, not ongoing serving. ## **Criteria that decide your egress bill** - **Cost per TB at your actual volume:** tiered metered rates, flat plans and committed plans cross over at different points. - **Billing model:** request fees, regional multipliers (Asia and South America often cost 2 times more or higher), minimums and commitments. - **Origin fetch cost:** what you still pay your cloud for cache misses, which depends on the byte hit ratio, not the request hit ratio. - **Protocol and feature fit:** HTTP/3, WebSockets, WAF, edge compute and large-object support. - **Switching cost:** DNS cutover, cache key parity, signed URL schemes and contract terms. ## **Egress vs ingress pricing at 100 TB a month: vendor comparison** | Vendor | Cost for 100 TB a month | Billing model | | --- | --- | --- | | BlazingCDN | $415 | Progressive per-TB tiers, one rate for US, Europe and Asia, no request fees | | bunny.net | $500 (Volume network), $1,000 (Standard) | Per-GB, rate depends on network tier | | CDN77 | $990 | One plan covering up to 250 TB | | Amazon CloudFront | From $1,000 (flat Premium) or $6,965 pay as you go | Flat plan, or regional per-GB plus request fees | | Gcore | About EUR 2,000 at list | Plans, negotiated at volume | | KeyCDN | $2,600 (North America, Europe), $5,200 (Asia) | Regional per-GB rates | | AWS region direct, no CDN | About $7,800 (our estimate) | Tiered internet egress per GB | At 100 TB a month, published price lists checked August 2026 put dedicated delivery CDNs between $415 and $1,000, against roughly $7,000 to $7,800 for metered cloud egress. BlazingCDN publishes this blog, so verify this ranking on your own traffic. The 14-day testing period exists for exactly that. ### Vendor by vendor **BlazingCDN** runs on NVMe SSD servers with Anycast routing, a 96%+ average cache hit ratio and objects up to 50 GB. It measured 24 ms and 1.11 Gb/s in North America and 27 ms and 1.12 Gb/s in Europe on a 100 MB HTTPS download (measured June 2026). Its limitations are real: no HTTP/3 or WebSockets, no WAF or DDoS mitigation (you keep your security stack beside it), and no free tier. Readers coming from AWS can check the line-by-line [**BlazingCDN vs Amazon CloudFront egress comparison**](https://blazingcdn.com/vs/aws-cloudfront/). As of November 2026, BlazingCDN bills delivery on progressive tiers from $5 per TB down to $2.50 per TB at volume, with one rate for US, Europe and Asia and no request fees. That works out to $415 for 100 TB and $765 for 200 TB a month. Current rates are listed on the BlazingCDN pricing page. **bunny.net** pairs low per-TB pricing with a broad product line. Its $500 rate applies to the Volume network, which is smaller than Standard, so latency-sensitive traffic may need the $1,000 tier. **CDN77** sells a plan that covers up to 250 TB, which makes growth cheap. At 100 TB, though, you pay for headroom you do not use. **Amazon CloudFront** fetches from S3 and EC2 origins at no transfer charge and integrates tightly with AWS security services. Its pay-as-you-go price at 100 TB is about 17 times the cheapest row before request fees. **Gcore** offers a wide edge and security portfolio, but its list price needs negotiation to compete on egress. **KeyCDN** keeps billing simple with no commitment, but Asia-heavy audiences double the bill. ## **Worked math: data transfer costs with an AWS origin** A CDN does not remove cloud egress. It shrinks it to the cache-miss fraction. The assumptions here: S3 origin, AWS list internet egress rates, 1 TB counted as 1,000 GB, the first 100 GB free, and request fees ignored. All figures are our estimates. | Scenario | 100 TB a month | 200 TB a month | | --- | --- | --- | | S3 direct to users | About $7,791 | About $13,791 | | Amazon CloudFront pay as you go (origin fetch $0) | $6,965 plus requests | $11,965 plus requests | | Amazon CloudFront flat Premium | From $1,000 | $3,500 | | BlazingCDN plus S3 origin, 96% byte hit ratio | $415 plus about $351 origin egress = about $766 | $765 plus about $711 origin egress = about $1,476 | | BlazingCDN plus S3 origin, 90% byte hit ratio | $415 plus about $891 = about $1,306 | $765 plus about $1,791 = about $2,556 | With a third-party CDN in front of AWS, origin egress becomes the largest variable cost, so byte hit ratio matters more than the CDN's own rate card. That yields a rule of thumb worth keeping. On an AWS origin, every percentage point of byte hit ratio is worth about $90 a month per 100 TB served. A long-tail video library at 90% pays roughly $540 more each month than the same library at 96%. That makes origin shield and request coalescing financial controls, not just latency tuning. For video libraries, BlazingCDN's Video CDN replicates the library inside the CDN so the origin leaves the delivery path. Permanent cache costs $0.02 per GB per month after the included 500 GB, so a 10 TB library costs about $190 a month to hold. ## **How to cut data transfer costs without changing vendors** 1. **Add S3 and DynamoDB gateway endpoints** so private-subnet traffic skips NAT Gateway processing at $0.045 per GB. 2. **Pin chatty services to one availability zone**, or use topology-aware routing in Kubernetes, to avoid $0.02 per GB round trips across zones. 3. **Compress text payloads** with Brotli or zstd. API responses and manifests often shrink by 70 to 80 percent. 4. **Audit cross-region replication** and replicate only the buckets that serve another region's users. 5. **Measure byte hit ratio separately from request hit ratio**. Large objects that miss dominate origin egress. 6. **Read usage types, not service totals**. In the Cost and Usage Report, split DataTransfer-Out-Bytes, DataTransfer-Regional-Bytes and NatGateway-Bytes before deciding what to fix. ## **Best fit by workload** | Workload | Best fit | Why | | --- | --- | --- | | Under 46 TB a month, mixed site traffic | Amazon CloudFront Business or Cloudflare Pro | Flat $200 or $25 plans beat any metered rate | | 100 TB and above of video, installers, patches or images | BlazingCDN or bunny.net Volume | $415 to $500 at 100 TB, no request fees on BlazingCDN | | AWS-native app needing WAF and bot controls | Amazon CloudFront Premium | Free origin fetch and bundled security | | HTTP/3, WebSockets or edge compute | Cloudflare, Fastly or Amazon CloudFront | Broader platform features | | Inter-AZ, NAT or cross-region spend | Architecture changes | No CDN touches internal traffic | Pick the CDN by workload and volume. A heavy static-delivery CDN beside a security-focused one is often cheaper than either alone. ## **FAQ: egress vs ingress and egress fees** ### Is ingress free on AWS, Azure and Google Cloud? Yes, ingress from the internet is billed at $0 on all three major clouds as of 2026. The catch is that some paths bill both directions. Inter-AZ traffic on AWS costs $0.01 per GB each way, and NAT Gateway processing applies to bytes in and out. Free ingress covers only the internet-to-region boundary, not traffic moving inside your own account. ### Why are cloud egress fees higher than CDN bandwidth prices? Cloud egress fees are priced as a retention lever, not at cost. AWS first-tier internet egress of about $0.09 per GB equals roughly $90 per TB. Dedicated delivery CDNs publish $2.50 to $10 per TB at 100 TB a month (price lists checked August 2026), because bandwidth is their product rather than the exit toll on a compute platform. ### Does a CDN eliminate cloud egress fees? No, a CDN reduces cloud egress to the cache-miss fraction rather than eliminating it. At a 96% byte hit ratio, 100 TB delivered still pulls about 4 TB from the origin, roughly $351 at AWS list rates. Amazon CloudFront is the exception for AWS origins because origin fetch is free, though its delivery rate per TB is higher. ### How much does 100 TB of egress cost per month? Serving 100 TB of egress directly from an AWS region costs about $7,800 at list rates, our 2026 estimate. Amazon CloudFront pay as you go is $6,965 plus request fees. As of November 2026, BlazingCDN charges $415 for 100 TB with one global rate and no request fees. Check the BlazingCDN pricing page for current rates. ## **Price your own egress vs ingress split this week** Export last month's Cost and Usage Report and group the data transfer line items by usage type: internet out, regional (inter-AZ), cross-region and NAT. Then pull byte hit ratio from your current CDN logs, or from origin bytes divided by delivered bytes. Multiply your miss bytes by your origin egress rate. That one number tells you whether a cheaper delivery rate or a better hit ratio saves more, and the exercise pays off even if you never switch vendors. If the internet-out line dominates, the [**BlazingCDN cost calculator for egress and data transfer costs**](https://blazingcdn.com/cdn-cost-calculator/) prices the same monthly volume on progressive tiers from $5 per TB, so you can compare it against your current bill.
