When a file lands in a folder you're watching, Files.com publishes a tidy message to your Pub/Sub Topic — or one a partner or another team owns — and Pub/Sub sends it to every Cloud Function, Cloud Run service, Dataflow job, and subscriber. No function sitting there watching a bucket to build or babysit.
Pub/Sub is great at one thing: publish a message to a Topic once, and it reaches every subscriber. What Pub/Sub doesn’t do is the file part — taking files in from partners over SFTP and FTPS, controlling who can touch which folder, and keeping an audit trail. Files.com does that part, and publishes a message to your Topic the moment a file lands. Your existing fan-out kicks off, and there’s no Cloud Function watching a bucket to get the event going.
When something happens in a folder you're watching, Files.com publishes a message to your Pub/Sub Topic — yours, or one a partner or another team owns — and Pub/Sub delivers it to everything subscribed. Files.com hands the message to Pub/Sub, and Pub/Sub takes it from there.
The message says what happened, where, by whom, from what address, over which protocol, and the file's name, type, and size. That's enough for a Cloud Function or Dataflow consumer to route and process the file without opening it first.
Instead of running a Cloud Function that listens for GCS bucket events to find out a partner's file showed up, let Files.com be the front door that takes the file in and publishes the event itself — with the access controls and audit trail a raw bucket path doesn't give you. You don't even need a GCS bucket; the event fires wherever the file lands.
Files can arrive over SFTP, FTPS, AS2, the API, an Inbox, or a Share Link — and any of those can fire the Pub/Sub event. So a partner who can only do SFTP still kicks off your Google Cloud pipeline.
The Topic can belong to another team, a vendor, or a partner running the downstream pipeline. They grant publish access on their Topic, and you add the credential.
Files.com publishes with a Google Cloud service account that can do one thing — put a message on the Topic, and nothing else. Setting up the event stream never widens what an attacker could reach in your Google Cloud project.
The event fires when a file lands over any path in — SFTP, FTPS, AS2, the API, an Inbox, or a Share Link — whether or not the storage behind the folder is Google Cloud Storage.
Files.com publishes one message per file operation, the instant it happens — no waiting, no lumping things together. A Cloud Function or Dataflow consumer reacts the moment a file lands.
Files.com records every event in its own audit log, separate from Pub/Sub. So the Pub/Sub stream is never your only record — the full trail is still there even if a subscriber misses a message.
A partner uploads a file over SFTP, Files.com publishes the event to Pub/Sub, a Cloud Function picks it up and processes the file, and a Dataflow job loads it. No function sitting there watching a bucket.
Every data feed that lands in Files.com fires a Pub/Sub event that kicks off a Dataflow job or a BigQuery load. Your analytics stay current instead of waiting on a job that runs on a timer.
One folder's activity publishes to a Topic that several Cloud Run services listen to on their own — one pulls metadata, one processes the document, one archives it — each reacting independently.
The who, where, and from-what-address details feed a subscriber that writes to your SIEM, turning file activity into security data your team can watch.
Your storage behind it all. Pointing Files.com at a GCS bucket and publishing Pub/Sub events is the classic Google Cloud setup.
