Varnish is a web accelerator platform, which caches info for faster response times. It is sometimes referred to as an HTTP reverse proxy too and it works between a web server and a browser. When a visitor loads a certain webpage, the content is requested by the Internet browser, and then the web server processes this browser request and returns the necessary information. If Varnish is enabled for a given website, it will cache the pages at the first visit and in case the visitor opens a cached page once again, the content will be delivered by the caching platform instead of the web server. The increased load speed is an end result of the significantly faster response speed that Varnish offers as compared to any server software. Of course, this doesn’t mean that the website visitors will keep being served the very same content again and again, because any modification on any of the pages is reflected in the content that the Varnish platform stores in its memory.

Varnish in Cloud Hosting

If you host your sites in a cloud hosting account with us, you will be able to add Varnish with several clicks via your hosting Control Panel. The platform comes as an upgrade with all our shared hosting packages and you can choose the number of the sites that will use it and the total amount of system memory 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 memory and they are not directly linked to each other, so you can choose whether you need plenty of memory for one single large-sized site or less memory for multiple smaller ones. You can unleash the full potential of the Varnish caching platform in case the sites use a dedicated IP. With the Control Panel, you can effortlessly start/reboot/deactivate an instance, clear the cached content individually for each website which uses the Varnish platform or check an in-depth system log.

Varnish in Semi-dedicated Servers

Varnish is part of the basic set of services that you’ll get if you choose to host your websites in a semi-dedicated server account. You can enable it for any of your Internet sites via our innovative Hepsia hosting Control Panel. The default system memory that the Varnish platform can use to cache data is 64 megabytes, but in case you decide that you want more, you can upgrade this memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, in other words – the number of the websites that can use this caching platform at the same time. As these two features aren’t tied to each other, you can use a couple of Internet sites with the default amount of memory or you can add more memory in increments of 32 megabytes and use all of it for one single Internet site. The Varnish platform performs best if you assign a dedicated IP address to the websites that utilize its power. Hepsia will offer you an easy way of restarting any instance. What’s more, you’ll be able to clear the cached data with only one mouse click.

Varnish in VPS Servers

We offer Varnish with all Hepsia-equipped Linux VPS servers, so if you get a VPS with this hosting Control Panel, you will be able to make use of the content caching platform at no extra fee. The Varnish platform can utilize different amounts of system memory for data caching purposes depending on the particular VPS plan that you’ve chosen during the order process, but at any rate, this amount won’t be less than several hundred MB. This is more than enough to enhance the overall performance of several different traffic-heavy websites, so the better website loading speeds and the lowered load on the virtual server will be noticeable. The result may not be visible momentarily, since Varnish will need some time to cache the website content that users request, but soon after you enable it, you will feel its full potential. This platform will allow you to use a less powerful Virtual Private Server and to pay less money to get the same performance you’d get with a higher-end virtual machine without Varnish.

Varnish in Dedicated Servers

When you want a powerful hosting solution and you buy one of the Linux dedicated web hosting plans that we offer, you’ll be able to use the Varnish data caching platform to enhance the performance of your sites at no additional fee on the condition that the dedicated server is ordered with our advanced Hepsia Control Panel. Its simple-to-use graphical interface will allow you to monitor system processes, to delete the cached content or to reboot any instance with one single mouse click. The minimum amount of memory that the caching platform can employ to cache website content is 3 gigabytes, which is more than enough for an enormous selection of large-sized sites, so your server will be able to handle a tremendous system load while your visitors are enjoying a smooth browsing experience. Since your dedicated server will include several dedicated IPs, you will be able to use Varnish’s full capacity.
