Limits

STRATUS has three types of instances - Autoscaling Instances, Development Instances, and Resource Base Pricing Instances.

Autoscaling Instances

Autoscaling instances are the default and recommended production instances for STRATUS. The autoscaling instances will scale out your website frontend horizontally and automatically in response to surges in traffic.

Autoscaling Instances have two types - Single tenant and Multi tenant.

Multi tenant - Starter, Pro, and Growth, have all services running across the shared STRATUS platform. The limits in the services are aggregated as a total.

Single tenant - Scale, and Enterprise, have a dedicated ec2 instance for their services except PHP. PHP is scaled across the shared STRATUS platform. The limits in the services are not aggregated as a total. The service limits are allowed to use the max resources in the dedicated ec2 instance.

Resource Based Pricing Instances

Discontinued: Resource Based Pricing instances are not recommended for most customers. These should only be used by customers running Magento 1 and Varnish enabled. Or for other types of software that are not Magento but need run beside a Magento store. They are not autoscaling. The limits in the services are aggregated as a total.
