Cut your AWS bill.
Keep your data.
S4 is a family of drop-in EC2 appliances that replace metered AWS services with predictable hourly pricing — storage, logs, metrics, NAT and more. No application changes, no lock-in.
Available on AWS Marketplace — hourly + annual, per instance type, no license keys.

Why S4
Replace a metered AWS service with an hourly appliance that runs inside your own VPC.
Predictable cost
Trade per-GB / per-request metering for a flat hourly fee. Your cost is decoupled from volume — no end-of-month surprises.
Zero app changes
Drop-in on the wire protocols you already use — S3-compatible, PutLogEvents-compatible and more. No code rewrites.
No lock-in
Output stays in standard formats (zstd, plain Parquet). Cancel the subscription and your data is still readable without our tools.
How S4 works
Every S4 product replaces a metered AWS service with an hourly appliance in your own VPC — in the same three steps.
- 1
Deploy into your VPC
Launch via AMI or CloudFormation inside your own AWS account and VPC. Your data never leaves your account.
- 2
Slot into your existing path
Drop in on the wire protocols you already use (S3-, PutLogEvents-compatible) or just repoint a route or endpoint. No application changes.
- 3
Save at a predictable price
Trade per-GB / per-series / per-scan metering for a flat hourly fee. Output stays in standard formats, so you can walk away any time.
