Online vs Offline Transfer Cost Comparator

What this free tool does for you

Choose how to move your data with the cost and the days in front of you. Internet, private connection and appliance are priced on the same inputs, with every rate dated.

How to use it

  1. Pick the Destination cloud and where your Data center and cloud region are.
  2. Enter the Data to move and the Days until the deadline.
  3. Describe Your internet link, then the Private connection you could order or already have.
  4. Adjust Physical transfer for how fast your storage copies and how long shipping takes.
  5. Compare the rows, then open each one to see what its cost is made of.

Good to know

  • Candidates, not advice. Change an assumption and the ranking can change. Each row shows what its figure is made of.
  • Snowball is gone. AWS closed it to new customers, so the AWS rows use DataSync, Direct Connect and the Data Transfer Terminal.
  • Save or share. Use Copy link to this result, under the answer, to get a link with your numbers filled in.

What this means

  • Lowest-cost candidate that meets the deadline

    AWS Data Transfer Terminal: about $7,500.00 one-time, in 18 days. It ranks first on the assumptions shown; change any of them and the ranking can change.

  • Your current link is too slow for this deadline

    Over the internet link the copy takes about 86 days.

  • A new private connection has a lead time

    Carriers usually need four to eight weeks to deliver a circuit; this page assumes 45 days. Order early if this row is the plan.

What this model assumes

Show
  • Ingress is free on all three clouds, so no row has a per-GB network charge for data arriving. The costs are the service, the circuit, the appliance and the days.
  • Private links run at 80%, all day, with 92% protocol efficiency, and are billed from 7 days before the copy for testing. Port prices are US list; European ports are within a few percent.
  • Appliances stay on site for the whole copy. They arrive together and your storage sets the fill rate, so every device pays daily fees for the full period. Loading into the cloud takes about 14 days on Google (it states about 10 business days) and 5 days on Azure (an assumption; Microsoft does not publish one).
  • Shipping is the published starting rate. Google lists freight from $120 to $500 a round trip by device and continent; Microsoft managed shipping for Data Box 120 and 525 is free.
  • The AWS terminal needs your own drives, which are not priced, and a booking at a terminal city. Upload rate is what your drives reach over the 100 GbE ports.
  • From another cloud, the source bills internet egress on its monthly tiers, starting again each month of copying, and the copy runs at the rate you set at 80%, all day. The second row assumes the source credits that egress because you are leaving it.
  • Not counted: object storage request charges, storage while the move runs, and source-side licenses.

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

Is it free to upload data to the cloud?

The network part is: AWS, Google Cloud and Azure charge nothing for inbound data transfer. The migration still costs money: the transfer service (DataSync and Storage Transfer Service charge $0.0125 a GB or GiB), a private circuit and its carrier, an appliance, and the weeks the move takes.

Is AWS Snowball still available?

Not to new customers. AWS stopped offering Snowball Edge to new customers on 7 November 2025, and support for all Snow devices in commercial regions ends on 31 December 2026. AWS points new customers to DataSync for online moves and the Data Transfer Terminal for physical ones.

When is a transfer appliance cheaper than the network?

Often for large moves with a deadline. Two Google Transfer Appliances for 450 TB list at about $4,000 with shipping, against $5,200 of Storage Transfer Service fees alone, and they are not limited by your link. The network wins when the link is fast enough and already paid for.

How much does a temporary Direct Connect or Interconnect cost?

The provider side is small: a 10 Gbps Direct Connect port is $2.25 an hour, a Dedicated Interconnect $2.328 plus $0.10 for the attachment. The carrier circuit, the cross-connect, the minimum term and the four to eight weeks it takes to deliver usually decide it.

What does Azure Data Box cost now?

The Next-Gen Data Box 120 and 525 have no service fee and no shipping fee with Microsoft managed shipping, with 10 days included, then $50 or $200 a day. Data Box Heavy is retired. For small moves, Data Box Disk is $50 an order plus $10 a disk a day.
