Varnish is a website accelerator tool, which has been gaining a lot of popularity in recent years, as it can increase the speed of any Internet site, sometimes even by 100 percent, depending on the content. This tool is sometimes referred to as an HTTP reverse proxy too and is used to reduce the overall load on the physical server and to improve the browsing speed for the website visitors. Every time a visitor opens a page on a particular site, the web browser request is processed by the web server and the requested data is served as a response. If Varnish is enabled, it caches the pages that the visitor browses and in case any of them is loaded once more, it’s served by Varnish and not by the web server directly. The boost in the overall performance is due to the fact that the accelerator handles the web requests considerably faster than any web server, which results in much faster browsing speeds for the site visitors. In case any data is modified meanwhile, the cached pages will also be updated the next time somebody opens them.

Varnish in Cloud Hosting

In case you host your Internet sites under a cloud hosting account with our company, you will be able to add Varnish with several clicks through your hosting Control Panel. The platform comes as an optional upgrade with all our shared hosting plans and you can select the number of the websites that will use it and the maximum amount of system memory 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’re not linked directly to each other, so you can choose whether you want a lot of memory for one large site or less memory for multiple smaller ones. You can unlock the full potential of Varnish in case the sites use a dedicated IP. Using the hosting Control Panel, you can swiftly start/reboot/deactivate an instance, clear the cached content independently for each site that uses Varnish or view an exhaustive system log.

Varnish in Semi-dedicated Servers

The Varnish data caching platform is an essential part of the standard set of services that you’ll acquire in case you decide to host your websites under a semi-dedicated server account. You can configure it for any of your Internet sites through our next-generation Hepsia Control Panel. The default amount of memory that the Varnish caching platform can use to cache content 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 websites that can use this caching platform simultaneously. As these two features are not bound to each other, you can use a couple of websites with the default amount of memory or you can get more memory in increments of 32 megabytes and use all of it for one single web site. The Varnish platform performs best when you assign a dedicated IP address to the Internet sites that utilize its power. Hepsia will offer you an easy means of restarting any instance. What’s more, you’ll be able to clear the cached contents with only one single click.

Varnish in VPS Servers

The Varnish content caching platform is included by default with each of the VPS servers that we offer as long as the machine is ordered with the Hepsia Control Panel, so you can boost the overall performance of your websites with just a few clicks. The more powerful the package, the more memory will be available to Varnish, but even with a less powerful plan, the platform will be able to utilize several hundred megabytes, so even if you run a number of websites, you will notice a considerable decrease in the server load and a much better website loading speed. The Varnish caching platform will have to work for a while as the visitors browse the web pages and once the site content has been cached, you’ll see the results. One of the upsides of using Varnish is that a less powerful and less high-priced plan will accomplish the exact same job as a more high-priced one without the platform, so not only will your Internet sites perform better, but you’ll also save a certain amount of cash.

Varnish in Dedicated Servers

If you order a dedicated server with the Hepsia Control Panel, you will acquire the Varnish platform at no extra charge and you will have complete control over it via a truly intuitive interface – you will be able to start, to remove or to reboot an instance, to check an elaborate log, to clear the cached content associated with any website and much, much more. The Varnish platform will have several gigabytes of system memory at its disposal, so even if you manage large-scale sites with an enormous number of visitors, you will notice the tremendously faster web page load times and the less load on the machine. This will become a fact shortly after you begin using the Varnish platform, since it will need a certain amount of time to cache the website content that people request. You can get the most out of the platform’s potential if the Internet sites that are using it also use a dedicated IP address, but since your dedicated 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.
