Varnish is a web app accelerator, which has been gaining a lot in popularity lately, because it can increase the load speed of any Internet site, at times even by 100%, based on the content. This tool is occasionally referred to as an HTTP reverse proxy too and is used to reduce the overall load on the physical machine and to accelerate the access speed for the website visitors. Whenever a visitor accesses a page on a particular site, the web browser request is handled by the web server and the requested content is returned as a reply. If the Varnish accelerator is enabled, it caches the pages that the site visitor browses and if any of them is loaded once more, it is served by Varnish and not by the server directly. The performance improvement comes from the fact that the accelerator processes the browser requests tremendously quicker than any web server, which leads to much faster browsing speeds for the website visitors. In case any data is edited in the meantime, the cached webpages will also be ‘refreshed’ the next time someone opens them.

Varnish in Cloud Hosting

Varnish is available as an optional upgrade with all our cloud packages. You can add it to your website hosting account via the Hepsia Control Panel, which comes with all shared web hosting packages and you will get a quite simple-to-work-with interface, which will grant you complete control over the caching platform. Using one-click fast-access controls, you can reboot or turn off any of the instances, in other words – Varnish will no longer work for a specific Internet site. You can also see a comprehensive system log or erase the cache associated with any of the sites. When you add Varnish to your hosting package, you’ll be able to choose the maximum amount of system memory that will be at your disposal for caching purposes and the number of the sites that will use Varnish. You can always add more memory in increments of 32 MB and, for top performance, you can get a dedicated IP address for the websites that will use Varnish. This will permit you to get the most out of your sites and to have a lot of satisfied visitors.

Varnish in Semi-dedicated Hosting

The Varnish data caching platform is an essential part of the standard set of services that you’ll acquire if you choose to host your websites under a semi-dedicated server account. You can configure it for any of your sites through our leading-edge Hepsia hosting Control Panel. The default amount of system memory that Varnish can use to cache data is 64 MB, but if you decide that you want more, you can upgrade this amount from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, i.e. the number of the sites that can use this caching platform simultaneously. As these two features aren’t linked to each other, you can use a couple of sites 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 site. The Varnish caching platform performs best if you use a dedicated IP for the sites that utilize its power. Hepsia will provide you with an easy means of rebooting any instance. What’s more, you will be able to delete the cached contents with only one mouse click.

Varnish in VPS Hosting

We offer Varnish with all Hepsia-managed Linux VPS hosting packages, so in case you purchase a VPS with this web hosting Control Panel, you’ll be able to make full use of the data caching platform at no extra cost. Varnish can use different amounts of system memory for caching purposes depending on the specific VPS package that you’ve picked during the VPS order process, but nevertheless, this amount will not be less than several hundred MB. This is quite enough to enhance the work of a handful of traffic-heavy Internet sites, so the better site loading speeds and the reduced load on the Virtual Private Server will be discernible. The effect may not be evident right away, since the Varnish platform will require a certain amount of time to cache the website content that visitors browse, but soon after you activate it, you’ll feel its full potential. This platform will permit you to use a less powerful VPS server and to pay less money to get the very same performance you would get with a more powerful virtual machine without Varnish.

Varnish in Dedicated Web Hosting

If you order a dedicated server with the Hepsia hosting Control Panel, you’ll acquire the Varnish content caching platform at no extra cost and you will exert complete control over it via an extremely easy-to-use GUI – you’ll be able to start, to disable or to reboot an instance, to see an exhaustive system log, to delete the cached files associated with any site and much, much more. Varnish will have several gigabytes of virtual memory at its disposal, so even if you own resource-intensive sites with plenty of visitors, you’ll notice the much faster site load speeds and the reduced load on the dedicated server. This will become a fact shortly after you start using Varnish, as it will require some time to cache the content that visitors browse. You can take full advantage of the platform’s potential in case the Internet sites that are using it also use a dedicated IP address, but since your dedicated server includes a few IP addresses by default, you will not have to pay anything on top of the monthly charge for the machine itself.
