Stratus is a multi-tenant architecture using micro-services to provide the ideal hosting enviroment for Magento. Certain services are restricted in terms of how much CPU and memory they can use to prevent memory leaks and other issues from affecting your site. Services that need fluid limits, like PHP, are handled differently.
The Redis, memcache, Nginx and Elasticsearch services all have lower memory limits with less than 4GB as a maximum. A majority of stores do not exceed them and our team can adjust them if needed, as we do monitor to see what stores are using more resources than others.
Varnish malloc is set to 1GB, and Varnish generally only has 1 GB of memory associated with it, assuming it can use it all. Static caching is disabled by default in the Magento 2 VCL so only FPC information is stored in Varnish while CloudFront is used for static asset caching.
PHP-FPM scales horizontally and is restricted to 50% of the CPU available on a physical node, and when autoscaling is enabled, it expands horizontally based on the CPU utilization.
We have several rate limits and other blocks in place on Mojo Stratus to prevent malicious attacks against our customer’s stores. The exact limits are not available publicly.
