I also recommend activating a free uptime service that checks that your site is always reachable: UptimeRobot .
There are also advanced monitoring systems that allow you to check the status of various services such as: PHP, MySQL, Web Server etc., but obviously we are talking about systems that need to be integrated ad hoc on individual projects.
It is worth it if the site needs to be constantly operational.
Also, don’t forget that CMS upgrades can consume more philippines country code mobile number resources over time, so be sure to monitor when you update.
There are different ways to manage the cache, and each project may require a custom configuration. In technical terms, this is called “tuning cache”.
Depending on the type of infrastructure, you can define the cache at the server level or at the browser level. The second is the most widespread, since it is also the easiest to configure as it only requires the installation of a plugin.
The most famous and the one I recommend is WP Rocket as it is very simple to set up and does not require any particular skills.
I also remember that for e-commerce projects cache management is more “complex”, therefore the advice is to always be followed by a professional.
An improperly set cache could “break” the layout of your website and therefore create usability problems.
Precisely on this last point we can report a recent case study we worked on. After careful attention to the CMS backend and configuration of the various plugins for the advanced management of Varnish Cache through WP Rocket, we realized that the VPS server configurations did not communicate well with the WordPress installation of the client website, therefore every time an article was published, the latter went into error 404 as the server did not clean the Varnish cache.
