Standard

Guide for understanding and configuring a Standard stack

The Standard stack introduces dynamic capacity by decoupling the web delivery layer from the backend services.

Architecture: An autoscaling web tier supported by a single “core” server.

How it Works: The web server is moved into a horizontally scaling layer that automatically expands or contracts based on real-time request demand. The core server processes and manages common backend services (databases, caching, search, NFS, and cron).

Best For: Applications prone to traffic spikes or those experiencing rapid growth that require immediate, automated scaling at the web tier.

Supported variants

Magento (type: standard-magento)
Shopware (type: standard-shopware)
