Varnish is a web accelerator tool, which has been gaining a lot of popularity in recent years, as it can increase the load speed of any site, at times even by 100%, depending on the content. This tool is sometimes called a caching HTTP reverse proxy as well and is used to reduce the overall load on the server and to boost the access speed for the website visitors. Every time a visitor opens a page on a particular Internet site, the browser request is handled by the web server and the requested information is served as a reply. If Varnish is enabled, it caches the web pages that the site visitor opens and in case any of them is accessed once more, it’s served by Varnish and not by the server directly. The boost in the overall performance is due to the fact that the accelerator processes the web requests tremendously faster than any web server, which leads to much faster browsing speeds for the visitors. If any data is edited meanwhile, the cached webpages will also be ‘refreshed’ the next time someone attempts to open them.

Varnish in Hosting

You can use Varnish’s potential and enhance the load speed of your websites irrespective of the hosting package that you’ve selected and you can enable and configure the platform with a few mouse clicks from the user-friendly interface offered by our advanced Hepsia Control Panel. During the process, you’ll be able to choose two different things – how many websites will use the Varnish platform, in other words – the number of instances, and how much content will be cached, in other words – the amount of system memory. The latter is offered in increments of 32 megabytes and is not tied to the number of instances, so you can use more instances with less memory and the other way around. If you’ve got lots of content on a certain Internet site and you gain a lot of site visitors, more system memory will give you a better result. You may also consider employing a dedicated IP address for the websites that will use the Varnish caching platform. Hepsia will provide you with simple one-click controls for shutting down or restarting any instance, for deleting the cache for any website and for viewing elaborate logs.

Varnish in Semi-dedicated Hosting

The Varnish content caching platform is part of the standard service set that you’ll get if you choose to host your Internet sites in a semi-dedicated server account. You can set it up for any of your websites via our next-gen Hepsia hosting Control Panel. The default amount of system memory that the Varnish caching platform can use to cache data is 64 MB, but in case you decide that you need more, you can upgrade this amount from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, in other words – the number of the sites that can use this caching platform simultaneously. Since these two features aren’t tied to each other, you can use a few websites with the default memory or you can get more memory in increments of 32 MB and use all of it for one single website. The Varnish caching platform works best if you use a dedicated IP for the websites that utilize its power. Hepsia will provide you with an easy means of rebooting any instance. In addition, you’ll be able to clear the cached contents with only one mouse click.

Varnish in VPS

Varnish is included by default with all Linux VPS offered by our company as long as the Virtual Private Server is ordered with the Hepsia Control Panel, so you can boost the overall performance of your sites with only a few clicks. The more powerful the plan, the more system memory Varnish will have at its disposal, but even with a lower-end package, the caching platform will be able to utilize several hundred megabytes, so even if you own several different Internet sites, you will notice a substantial decrease in the overall server load and a tremendously faster page load speed. The Varnish platform will need to work for a little while while the visitors browse the web pages and as soon as the site content has been cached, you will notice the effect. One of the upsides of using Varnish is that a less powerful and less expensive VPS plan will accomplish the exact same job as a more pricey one without the platform, so not only will your sites work better, but you will also spare some money.

Varnish in Dedicated Hosting

If you order a dedicated server with the Hepsia hosting Control Panel, you’ll get the Varnish platform at no extra fee and you’ll have full control over it through an exceptionally easy-to-navigate interface – you will be able to start, to remove or to restart an instance, to check a comprehensive log, to delete the cached files associated with any Internet site and much, much more. The Varnish caching platform will have several GB of virtual memory at its disposal, so even if you have resource-hungry sites with a vast number of visitors, you will notice the significantly better web page load speeds and the lowered load. This will happen soon after you start using Varnish, since it will require a certain amount of time to cache the site content that users request. You can make the most of the platform’s capability if the Internet sites that are using it also use a dedicated IP, but since your dedicated server comes with a couple of IPs by default, you will not have to pay anything on top of your monthly charge for the machine itself.
