For best performance, stability and functionality we have documented some recommendations for running a Nextcloud server.
If you plan a setup for your organization and you rely on professional deployment consulting (e.g. efficient and reliable scaling) and support, we strongly recommend you to check out our enterprise support.
Operating System (64-bit)
See Installation on Linux for minimum PHP-modules and additional software for installing Nextcloud.
CPU Architecture and OS
A 64-bit CPU and 64-bit OS is required for Nextcloud 26 and higher.
Memory requirements for running a Nextcloud server are greatly variable, depending on the numbers of users, apps, files and volume of server activity.
Nextcloud needs a minimum of 128MB RAM per process, and we recommend a minimum of 512MB RAM per process.
Database requirements for MySQL / MariaDB
The following is currently required if you’re running Nextcloud together with a MySQL / MariaDB database:
InnoDB storage engine (MyISAM is not supported)
“READ COMMITTED” transaction isolation level (See: Database “READ COMMITTED” transaction isolation level)
Disabled or BINLOG_FORMAT = ROW configured Binary Logging (See: https://dev.mysql.com/doc/refman/5.7/en/binary-log-formats.html)

Why we drop old PHP versions
Every year, a new PHP version is added and old PHP versions are deprecated. This also affects our documented recommended PHP version.
We try to support old PHP versions for as long as reasonably possible. However the list of security, performance, and bug fixes will only increase, some of those fixes might be considered critical and thus at some point the deprecation will be inevitable.
Thus it is recommended to keep your PHP version up to date.
Advantages of upgrading PHP
PHP deprecates security fixes of old versions. Nextcloud cannot implement security fixes that come with new PHP versions as long as we support deprecated PHP versions, since the syntax that we are allowed to use must be the lowest one of the supported versions, thus the upstream packages of third parties break because they dropped this support.
The language continuously improves over time which makes it possible to do more requests in significantly less time.
Long term support
If you are running Nextcloud for an organisation-critical use case, you could consider upgrading your subscription to a premium subscription which comes with 5 years of long term support. This means you continue to receive maintenance releases for high and critical security issues, data loss fixes, and regressions within version over this extended period of time.
We strongly recommend using the latest version of your operating system to get the full and most stable experience out of our clients.
macOS Lion (10.7)+ (64-bit only)
Linux (CentOS 6.5+, Ubuntu 14.04+, Fedora 21+, openSUSE 13, SUSE Linux Enterprise 11 SP3+, Debian 8 (Jessie)+, Red Hat Enterprise Linux 7)
We strongly recommend using the latest version of your mobile operating system to get the full and most stable experience out of our mobile apps.
Nextcloud Server 14.0+
Nextcloud Talk 4.0+
When using Nextcloud Talk 12.0+ please update the Android Talk App to the newest version (or at least to v12.1).
For the best experience with the Nextcloud web interface, we recommend that you use the latest and supported version of a browser from this list, or one based on those:
If you want to use Nextcloud Talk you should use Mozilla Firefox 52+ or Google Chrome/Chromium 49+ to have the full experience with video calls and screensharing. Google Chrome/Chromium requires an additional plugin for screensharing.
