Varnish is a content caching platform, which is occasionally called a caching HTTP reverse proxy. It’s a web application accelerator that can improve the speed of a site by up to one thousand percent, depending on its content. Each time a visitor opens any page on a site that uses Varnish, the platform caches the page and delivers it instead of the web server when the visitor accesses it again. In this way, the web browser request from the visitor is not processed by the server and the web page will open significantly faster, since the Varnish platform can deliver information many times faster than any server software. The result is a much faster loading page, which means a much-improved website browsing experience. When any of the cached webpages is updated on the live Internet site, the content that Varnish keeps in its memory is ‘refreshed’ as well, so the visitors won’t see old content.

Varnish in Hosting

Varnish is available as an optional upgrade with all our Linux hosting service. You can add it to your web hosting account via the Hepsia Control Panel, which is offered with all shared web hosting plans and you will get an amazingly intuitive GUI, which will grant you complete control over the content caching system. Using 1-click fast-access controls, you can reboot or turn off any of the instances, in other words – Varnish will no longer be activated for a certain Internet site. You can also view a detailed log file or clear the cache for any of the Internet sites. When you add Varnish to your web hosting plan, you’ll be able to select the total amount of memory that will be at your disposal for caching purposes and the number of the websites that will use Varnish. You can always order more memory in increments of 32 MB and, for optimal performance, you can allocate a dedicated IP to the websites that will use Varnish. This will allow you to get the most out of your websites and to have lots of happy website visitors.

Varnish in Semi-dedicated Servers

The Varnish content caching platform is part of the default service set that you will receive if you decide to host your sites under a semi-dedicated server account. You can enable it for any of your sites via our cutting-edge Hepsia hosting Control Panel. The default memory that the Varnish caching platform can use to cache data is 64 MB, but in case you decide that you want more, you can upgrade this amount of memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, in other words – the number of the sites that can use this caching platform at the same time. Since these two things aren’t tied to each other, you can use several instances with the default amount of memory or you can get more memory in increments of 32 MB and use all of it for a single website. The Varnish platform performs best if you use a dedicated IP for the Internet sites that utilize its power. Hepsia will provide you with an easy way of rebooting any instance. What’s more, you will be able to clear the cached files with only one click.

Varnish in VPS Servers

The Varnish content caching platform comes by default with all Linux VPS servers offered by us given that the VPS server is ordered with the Hepsia Control Panel, so you can optimize the performance of your sites with only a few mouse clicks. The more powerful the plan, the more memory will be available to Varnish, but even with a low-end plan, the platform will be able to utilize several hundred megabytes, so even if you’ve got several Internet sites, you’ll notice a noticeable reduction in the server load and a significantly faster webpage loading speed. The Varnish caching platform will have to work for a little while as the visitors navigate the web pages and once the site content has been cached, you will notice the effect. One of the advantages of employing Varnish is that a lower-end and less pricey package will do the same job as a more high-priced one without the platform, so not only will your Internet sites work substantially better, but you’ll also save a certain amount of money.

Varnish in Dedicated Servers

If you order a dedicated server with the Hepsia hosting Control Panel, you will obtain Varnish at no extra fee and you’ll have total control over it through a quite simple-to-use GUI – you’ll be able to start, to cancel or to reboot an instance, to view a comprehensive log, to delete the cached files for any site and much more. Varnish will have several GB of system memory at its disposal, so even if you run regularly visited websites with plenty of visitors, you’ll notice the tremendously better web page loading speeds and the less load on the dedicated server. This will happen soon after you start using the Varnish platform, since it will require some time to cache the web pages that users access. You can get the most out of the platform’s potential in case the sites that are using it use also a dedicated IP, but since your server comes with a couple of IPs by default, you won’t have to pay anything on top of the monthly charge for the server itself.
