Understanding Auto-Scaling with AutoPress

By John Smith, Lead Engineer

Never Worry About Traffic Again

One of the core promises of AutoPress is effortless scalability. But what does “auto-scaling” truly mean in our serverless context? Let’s break it down.

Traditional Scaling vs. Serverless Auto-Scaling

Traditionally, scaling WordPress involved:

  • Vertical Scaling: Increasing resources (CPU, RAM) on a single server. This has limits and can be expensive.
  • Horizontal Scaling: Adding more servers behind a load balancer. This adds complexity in management and configuration.

AutoPress takes a different approach, akin to how modern cloud functions (like AWS Lambda or Google Cloud Functions) operate:

  1. Event-Driven Execution: When a request hits your AutoPress site, it triggers the necessary WordPress functions.
  2. Ephemeral Instances: These functions run in lightweight, isolated compute instances.
  3. Scale On Demand: If 100 users visit your site simultaneously, AutoPress can spin up 100 (or more, depending on the task) instances to handle those requests in parallel. If traffic drops to 10 users, resources scale down automatically.
  4. No Pre-Provisioning: You don’t need to guess your capacity needs beforehand.

This means your site remains fast and responsive, whether you have ten visitors or ten thousand, without any manual intervention or configuration changes on your part.
