What Does Google Pub/Sub Do?

Google Cloud Pub/Sub is a fully managed messaging service that enables event-driven communication between systems. It allows applications to publish events to a topic and have other systems automatically subscribe and react, without direct system-to-system connections.

When integrated with Files.com, Pub/Sub powers event-driven file automation.

As files are uploaded, downloaded, moved, or deleted in Files.com, events can be published to Google Pub/Sub in real time. These events can then trigger downstream services such as Cloud Run, Cloud Functions, Dataflow pipelines, security monitoring tools, or custom workflows.

This eliminates polling, reduces latency, and ensures that your file-based processes run immediately and automatically.

Conversely, Pub/Sub messages can also be used to trigger actions within Files.com (such as moving files, initiating transfers, or launching automations) creating a fully automated, multi-directional workflow between your file platform and your cloud infrastructure.

Why Use Files.com with Google Pub/Sub?

Files.com turns your file workflows into real-time, event-driven processes by extending your site directly into Google Cloud Pub/Sub. Instead of relying on scheduled checks or manual monitoring, Files.com can publish file activity events as they happen, allowing your systems to react instantly.

Because Files.com acts as the central hub for file transfers, integrations, and collaboration, every important file event can become a trigger. Whether files arrive through SFTP, FTPS, AS2, APIs, Inboxes, or Share Links, Files.com can immediately publish those events to Pub/Sub, enabling downstream services to process, analyze, or route files automatically.

This makes Pub/Sub a powerful extension of your Files.com site. Your file platform becomes the entry point for automation across your broader cloud infrastructure -triggering workflows in Cloud Functions, Cloud Run, Dataflow pipelines, security monitoring tools, or other event-driven services.

Combined with Files.com’s security controls, audit logging, encryption options, and automation capabilities, Pub/Sub integration allows organizations to build scalable, reliable file pipelines without adding complexity to their infrastructure.

With Files.com and Google Pub/Sub working together, file activity doesn’t just get stored - it drives the systems and workflows that depend on it.

How Enterprises Use Google Cloud Pub/Sub with Files.com

Trigger Cloud Workflows When Files Arrive

Many enterprises use Files.com as a secure landing zone for files from partners, vendors, and internal systems. When a file is uploaded via SFTP, API, Inbox, or Share Link, Files.com can publish an event to Google Cloud Pub/Sub. This allows cloud services such as Cloud Functions or Cloud Run to automatically begin processing - without waiting for scheduled jobs or manual intervention.

Power Event-Driven Data Pipelines

Data engineering teams often rely on Files.com to collect incoming data feeds from partners or external systems. Pub/Sub allows each file delivery to immediately trigger downstream pipelines—such as loading data into BigQuery, launching Dataflow jobs, or initiating validation processes—so analytics systems stay continuously up to date.

Coordinate Microservices Across Cloud Systems

Large organizations frequently run distributed applications that need to react to file activity. By publishing file events to Pub/Sub, Files.com allows multiple services to subscribe and respond independently—triggering tasks like metadata extraction, document processing, archiving, or system notifications across different applications.

Is Google Cloud Pub/Sub Free?

Google Cloud Pub/Sub offers a free tier, which includes a limited amount of message throughput each month. This allows developers and teams to experiment with event-driven systems without immediate cost. However, beyond the free tier, Pub/Sub pricing is based on the volume of data published, delivered, and stored.

When used with a file platform like Files.com, Pub/Sub events can be triggered whenever files are uploaded, downloaded, or modified—allowing organizations to automate file workflows while scaling costs based on actual usage.
