Stratus Limits

Mojo 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 Mojo Stratus. The autoscaling instances will scale out your website frontend horizontally and automatically in response to surges in traffic.

Autoscaling Instance 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.
