MINIMUM HARDWARE REQUIREMENTS

or a frame of reference, Artefactual’s standard AtoM test/demo site deployment is a cloud VM with the following specifications:

• Processor: 2 vCPUs @ 2.3GHz
• Memory: 7GB
• Disk space (processing): 50GB at a minimum for AtoM’s core stack plus more storage would be required for supporting any substantial number of digital objects.

Software dependencies (required)

These are the minimum requirements, but please remember that in most of the cases you’ll experience better results working with the latest stable releases of each component.

• A webserver like Apache or Nginx; Artefactual prefers the latter in development
• Elasticsearch 5.x (we use ES 5.6 in development). Elasticsearch 6.0 or newer is not supported as they have deprecated a number of APIs still used in AtoM
• Java 8 (required for Elasticsearch)
• MySQL 8.0
• PHP 7.4
• Gearman job server

Optionally, Memcached can be used as cache engine:

• Memcached

Additionally, the following PHP extensions are mandatory:

• cURL
• JSON
• APC (apcu-bc also required)
• PDO and PDO-MySQL
• XSL

And the following PHP extensions are optional:

• Readline (not available in Windows).
• Memcache (needs`php-memcache`, not php-memcached).
