Overview
S4 Logs Commercial cuts the two big lines on a CloudWatch Logs bill: ingest and storage. Mode A drains existing log groups to S3 as standard zstd, cutting the storage line by 50-70% on S3 Standard and around 90% with Glacier Instant Retrieval. Mode B is a PutLogEvents-compatible gateway that writes straight to the archive, bypassing ingest - the dominant cost for most accounts and the source of the headline 70-90% reduction.
Archives are deliberately lock-in-free: every object is standard zstd, readable with plain zstd -dc, the open-source s4logs CLI, or Amazon Athena. Cancel the subscription and your data stays fully usable.
The commercial layer adds what enterprises need on top of the open-source core:
-
AWS Organizations multi-account drain: discover member accounts (all, by OU, or explicit), assume a drain role deployed via the included StackSet template, and drain every account into one aggregate bucket with per-account partitions. Retention gates are fail-closed.
-
WORM retention: S3 Object Lock in Governance or Compliance mode (SEC 17a-4). Every object is integrity-verified against its manifest before locking; a verification failure leaves the object mutable instead of locking a diverging copy. A per-object audit JSON is emitted for evidence.
-
Cost-savings dashboard and restore-search web UI: a single token-gated binary showing estimated monthly savings, per-group breakdowns, and a search-then-restore workflow that reads only manifest-pruned ranges from S3.
Deployment is one-click: the included CloudFormation quickstart creates an Object-Lock-enabled archive bucket, an instance role, and the dashboard instance. The AMI ships both the open-source s4logs CLI and the commercial s4logs-pro binary. No license keys - running the AMI is the entitlement. Billed hourly with an annual option.
Highlights
- AWS Organizations multi-account drain into one lock-in-free archive
- WORM / S3 Object Lock (Governance + Compliance), verified before locking
- Cost-savings dashboard + restore-search UI (single binary)

Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.
Version release notes
Adds a CloudFormation Quick Launch delivery option. Software identical to version 1.1.1.
