Varnish is a website accelerator, which has been gaining a lot in popularity in recent years, as it can increase the loading speed of any site, at times even by 100 percent, depending on the content itself. This tool is sometimes referred to as a caching HTTP reverse proxy too and is used to lower the overall load on the physical machine and to enhance the access speed for the website visitors. Each time a visitor accesses a page on a certain site, the browser request is taken care of by the web server and the requested information is returned as a reply. If the Varnish accelerator is activated, it caches the pages that the site visitor opens and in case any of them is accessed for a second time, it’s fetched by Varnish and not by the web server directly. The performance increase is due to the fact that the accelerator handles the browser requests tremendously faster than any web server, which results in much faster browsing speeds for the users. If any data is modified in the meantime, the cached webpages will also be ‘refreshed’ the next time somebody tries to access them.

Varnish in Shared Web Hosting

If you host your sites in a shared web hosting account with our company, you will be able to add Varnish with several mouse clicks via your hosting Control Panel. The platform is offered as an upgrade with all our shared packages and you can select the number of the sites that will use it and the total storage space that will be used 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 tied to each other, so you can choose if you need plenty of memory for one single large-size website or less memory for multiple smaller ones. You can take advantage of the full potential of the Varnish caching platform in case the sites use a dedicated IP address. Using the hosting Control Panel, you can easily start/reboot/remove an instance, clear the cached files individually for each website which employs Varnish or see an in-depth log.

Varnish in Semi-dedicated Servers

All our semi-dedicated plans include Varnish by default, so you can make full use of the web app accelerator tool and accelerate the load speed of any website that you host on our platform. You will get 64 MB of system memory exclusively for Varnish at no extra fee and you’ll be able to add an instance with no more than a few mouse clicks from the Hepsia hosting Control Panel, which is included with the semi-dedicated server plans. If you want more memory, the latter is offered in increments of 32 MB through the Control Panel’s Upgrades section and it will be at your disposal right away. You can also add more instances as a separate upgrade, so you can decide if a lot of data will be cached for a single website or if the available memory will be used by several Internet sites. The Hepsia Control Panel will permit you to restart or to delete any instance, to view the system log file associated with it or to clear the cached data using one-click buttons. To get the most out of the Varnish accelerator, you can assign a dedicated IP to the websites which will use it.

Varnish in VPS Servers

You can use Varnish with any of our VPS server plans at no additional charge, since the data caching platform is pre-installed and is offered by default. The only requirement is that the VPS must come with the Hepsia hosting Control Panel, via which you’ll be able to activate Varnish for any of your Internet sites with only a couple of mouse clicks. Each VPS plan comes with a different amount of system memory for caching purposes, but you will get no less than several hundred megabytes, which is enough even for several frequently visited Internet sites. Shortly after you activate Varnish, it’ll begin caching the content that your website visitors access, so you’ll notice the significantly better website load times and the decreased load on the VPS server very soon. Varnish will allow you to use a less high-priced VPS server, as you will not require that many resources to guarantee the correct operation of your Internet sites even if you own resource-demanding sites with plenty of visitors. Optimal results are achieved if the Internet sites which use Varnish also use a dedicated IP address.

Varnish in Dedicated Servers

All Linux dedicated servers which are ordered with the custom-built Hepsia website hosting Control Panel feature Varnish, which is among the pre-installed software platforms that you will get with the dedicated server. The Varnish caching platform can be set up and managed without efforts from Hepsia’s time and effort saving graphical interface and, with no more than one single mouse click, you can check an exhaustive system log, create or restart an instance, clear the cached content for any website and much more. Shortly after you activate the Varnish platform for a certain domain or sub-domain, it will begin caching the webpages requested by your visitors and as soon as it has cached enough content, you’ll observe a considerably better site performance and a reduced load. With Varnish-dedicated memory starting at three gigabytes, you will be able to use the platform for workload distribution purposes even if you host a lot of websites on your dedicated machine.
