Architecture Placement Comparator
Compare the monthly data transfer cost of two placements of the same system, path by path, on any cloud.
Each one fills in the fields below for a typical workload of that kind. You can change any of them.
Monthly traffic, in TB, by where it goes, for each placement.
Placement A
Placement B
Projection
- Placement A
- $3,612.20
- Placement B
- $3,012.20
- Over three years
- -$26,208.00
Network list prices; negative means B costs less.
By traffic path, a month
| Path | A | B | B minus A |
|---|---|---|---|
| Same zone | $0.0020 TB | $0.0050 TB | $0.00 |
| Another zone, same region | $160.008 TB | $160.008 TB | $0.00 |
| Another region, same continent | $600.0030 TB | $0.000 TB | -$600.00 |
| Backup or DR region | $60.003 TB | $60.003 TB | $0.00 |
| Your data center | $200.0010 TB | $200.0010 TB | $0.00 |
| Public internet | $2,592.2030 TB | $2,592.2030 TB | $0.00 |
| Total | $3,612.20 | $3,012.20 | -$600.00 |
Over three years
What this means
- Placement B costs less to run
$600.00 a month less than Placement A, $7,200.00 a year and $26,208.00 over three years with the growth you set.
- Most of the difference is another region, same continent
$600.00 a month in A against $0.00 in B, 100% of the gap.
What this model assumes
Show
- Each placement is priced on its own cloud and continent, with the same rates and rules as the Cloud Egress Cost Calculator: internet tiers shared by every internet-bound path, cross-zone charged the way each cloud charges it.
- Move traffic, do not delete it. A placement change usually turns one kind of traffic into another, cross-region into same-zone for example. The page warns when the two totals differ.
- Growth reprices each year on both sides, so larger volumes fall into cheaper internet tiers.
- Not counted: compute, storage and licenses that a placement also changes, private connection ports, NAT and load balancer processing, CDN requests, and negotiated discounts.
Prices verified 18 Oct 2026. Public list prices in USD for North America and Europe, before any discount you have negotiated.
Planning the target architecture?
Cloud Cost Audit: We review placement, network design and egress before the first bill arrives, so the migration does not carry avoidable transfer costs into the cloud. From $1,500, fixed. Nothing paid upfront.
Questions
Does region placement change the data transfer bill?
Often more than anything else. Traffic inside a zone is free, across zones it is a cent or two a GB on AWS and Google Cloud, between regions $0.02, and between North America and Europe up to $0.05. An application reading its storage from another region pays that on every byte, every month.
Is a multi-region architecture more expensive?
In data transfer, yes: replication and cross-region reads are billed by the GB. That can be the right trade for availability. This page shows what it costs, so the choice is made with the number.
Can I compare the same architecture on two clouds?
Yes. Set each placement to a different cloud with the same traffic. Remember that network is one line of the bill; compute, storage and discounts usually decide the choice of cloud.
Where do I get the traffic numbers?
From your bill, if the system already runs: data transfer lines grouped by usage type. For a new design, estimate the bytes each component sends to each other one, and start from a scenario.

Placement is cheap to change on paper and expensive to change later.
Finitizer splits your real data transfer by path and workload, so a placement review starts from what the system sends today rather than from estimates.
