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. Pub/Sub sends it to every Cloud Function, Cloud Run service, Dataflow job, and subscriber. So there's 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. That means 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. The Topic can be yours, or one a partner or another team owns. Pub/Sub delivers the message to everything subscribed, so the work fans out the moment the file arrives and nothing has to poll for it.
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.
Today you run a Cloud Function that listens for GCS bucket events just to find out a partner’s file showed up. Let Files.com be the front door instead. It 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, since the event fires wherever the file lands.
Files can arrive over SFTP, FTPS, AS2, the API, an Inbox, or a Share Link. 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, you add the credential, and your files start feeding their pipeline without either side building a bridge.
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, whether or not the storage behind the folder is Google Cloud Storage. SFTP, FTPS, AS2, the API, an Inbox, or a Share Link all work.
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.

Files.com builds deeply on Google Cloud Storage, Drive, and Workspace, so of course we’ll be on the floor at Google Cloud Next telling our File Orchestration story. The legacy MFT vendors won’t be there.
