Varnish is a data caching platform, which is sometimes referred to as an HTTP reverse proxy. It’s a web accelerator tool that can increase the loading speed of a site by up to 1000%, based on the content itself. Every time a visitor accesses any page on a website that uses Varnish, the platform caches the page and delivers it instead of the web server in case the visitor opens it again. Thus, the web browser request from the visitor is not handled by the web server and the page will open significantly faster, as the Varnish platform can deliver data many times faster than any web server software. The end result will be a substantially faster loading site, which leads to an enormously improved browsing experience. In case any of the cached webpages is updated on the live site, the info that Varnish keeps in its system memory is ‘refreshed’ too, so the website visitors will not end up seeing outdated content.

Varnish in Hosting

If you host your Internet sites under a hosting account with us, you’ll be able to activate Varnish with a few clicks from your hosting Control Panel. The data caching platform is offered as an upgrade with all our web hosting packages and you can choose how many websites will use it and the total storage space that will be available for the cached data. The two features that can be upgraded in the Control Panel’s Upgrades section are the number of instances and the amount of system memory and they are not directly linked to each other, so you can decide if you need a lot of memory for a single large-size website or less memory for several smaller ones. You can make use of the full potential of the Varnish platform in case the sites use a dedicated IP. With the Control Panel, you can quickly start/restart/terminate an instance, clear the cached content individually for each site which uses the Varnish platform or check an in-depth log.

Varnish in Semi-dedicated Servers

Varnish is a feature, which is offered as standard with all semi-dedicated servers offered by us and you can use it for load distribution purposes. It’s available in your Hepsia hosting Control Panel. The platform comes with 64 MB of system memory for cached content storing purposes and you can use it with any website that you host in the semi-dedicated account. In case you are in need of more than that, you can increase the system memory allowance. The memory itself is offered in increments of 32 megabytes in the Upgrades section of the Control Panel. The very same Upgrades section will allow you to add more instances as well, if you would like to use the Varnish caching platform with multiple websites. The two upgrades can be ordered separately – you can cache the content of one single busy Internet site or use several Internet sites with the default memory allocation. You can get the most out of Varnish in case you’ve got a dedicated IP address and you can order one with your semi-dedicated plan as well. Hepsia will give you total control over the caching platform and, with no more than one click of the mouse, you’ll be able to delete the cache, to check a system log file or to restart an instance.

Varnish in VPS Servers

Varnish comes by default with each of the VPS service offered by our company as long as the VPS is ordered with the Hepsia Control Panel, so you can improve the overall performance of your sites with just a few mouse clicks. The more powerful the package, the more memory Varnish will have at its disposal, but even with a low-end package, the platform will be able to utilize several hundred megabytes, so even if you have several sites, you will notice a great decrease in the overall server load and a considerably better site load speed. The platform will have to work for a little while as the visitors navigate the website and as soon as the site content has been cached, you will see the effects. One of the advantages of employing Varnish is that a lower-end and less high-priced VPS plan will accomplish the very same job as a more pricey one without the platform, so not only will your websites work significantly better, but you will also save a certain amount of money.

Varnish in Dedicated Servers

If you order a dedicated server with the Hepsia hosting Control Panel, you’ll get the Varnish data caching platform at no extra fee and you’ll have total control over it via a really simple-to-navigate graphical interface – you will be able to start, to cancel or to restart an instance, to see an in-depth log, to delete the cached files for any website and much more. Varnish will have several GB of system memory at its disposal, so even if you have heavy Internet sites with multiple visitors, you’ll notice the substantially better web page loading times and the decreased load on the dedicated machine. This will happen shortly after you begin using the Varnish platform, as it will need a certain amount of time to cache the web pages that visitors request. You can take full advantage of the platform’s capability in case the Internet sites that are using it also use a dedicated IP, but owing to the fact that your server includes a couple of IP addresses by default, you won’t have to pay anything on top of the monthly fee for the machine itself.
