Magento 2 Software Recommendations

Link

We require the following software for production instances of Commerce:

PHP
Nginx and PHP-FPM
MySQL
Elasticsearch or OpenSearch
For multi-server deployments, or for merchants planning on scaling their business, we recommend the following:

Varnish cache
Redis for sessions (from 2.0.6+)
A separate Redis instance as your default cache (do not use this instance for page cache)
See system requirements for information about supported versions of each type of software.

This table shows versions of third-party software dependencies that Adobe has tested with specific Adobe Commerce and Magento Open Source releases.

Adobe only supports the combination of system requirements described in the following table.
