Varnish is a data caching platform, which is occasionally called a caching HTTP reverse proxy. It’s a web accelerator tool that can increase the loading speed of a site by up to 1000%, depending on the content itself. Anytime a visitor accesses any page on a site that uses Varnish, the platform caches the page and delivers it instead of the web server when the visitor opens it again. In this way, the web browser request from the visitor is not handled by the server and the web page will load substantially faster, since the Varnish platform can deliver information many times faster than any server software. The end result is a significantly faster loading site, which leads to a greatly improved browsing experience. If any of the cached pages is updated on the live website, the content that Varnish stores in its system memory is updated too, so the users will never see old data.

Varnish in Cloud Hosting

In case you host your sites under a cloud hosting account with us, you will be able to add Varnish with a couple of clicks through your hosting Control Panel. The content caching platform comes as an optional upgrade with all our shared hosting plans and you can choose the number of the sites that will use it and the total amount of system memory that will be available for the cached content. The two features that can be upgraded in the Control Panel’s Upgrades section are the amount of memory and the number of instances and they aren’t linked directly to each other, so you can choose whether you need plenty of memory for one large-size site or less memory for multiple smaller ones. You can make use of the full potential of the Varnish platform if the sites use a dedicated IP address. Using the Control Panel, you can swiftly start/restart/disable an instance, clear the cached data individually for each site which employs Varnish or view a comprehensive system log file.

Varnish in Semi-dedicated Servers

Varnish is part of the default service set that you will receive in case you decide to host your sites under a semi-dedicated server account. You can enable it for any of your Internet sites via our next-gen Hepsia hosting Control Panel. The default system memory that the Varnish platform can use to cache data is 64 MB, but in case you decide that you need more, you can upgrade this memory from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, in other words – the number of the Internet sites that can use this caching platform simultaneously. As these two features are not linked to each other, you can use a couple of instances with the default memory or you can get more memory in increments of 32 MB and use all of it for one single web site. Varnish works best if you use a dedicated IP for the sites that utilize its power. Hepsia will offer you a simple means of restarting any instance. Also, you’ll be able to clear the cached contents with just one click.

Varnish in VPS Servers

Varnish comes by default with all VPS plans that we are offering on the condition that the virtual server is ordered with the Hepsia Control Panel, so you can enhance the performance of your websites with just a few clicks of the mouse. The more powerful the plan, the more memory Varnish will have at its disposal, but even with a low-end package, the caching platform will be able to utilize several hundred megabytes, so even if you run a number of Internet sites, you will notice a considerable reduction in the server load and a substantially better site load speed. The platform will need to work for a little while as the visitors navigate the website and as soon as the website content has been cached, you will distinguish the result. One of the benefits of employing Varnish is that a less powerful and less costly Virtual Private Server package will do the same job as a more high-priced one without the caching platform, so not only will your websites perform substantially better, but you’ll also spare some cash.

Varnish in Dedicated Servers

If you order a dedicated server with the Hepsia hosting Control Panel, you’ll get Varnish at no additional charge and you will exert full control over it via a truly intuitive GUI – you will be able to start, to remove or to restart an instance, to see an in-depth system log, to clear the cached content associated with any website and much, much more. The Varnish caching platform will have several gigabytes of memory at its disposal, so even if you host traffic-intensive Internet sites with numerous visitors, you’ll notice the significantly better page loading speeds and the reduced load on the dedicated machine. This will happen shortly after you begin using Varnish, since it will need a certain amount of time to cache the site content that visitors access. You can make the most of the platform’s capacity if the Internet sites that are using it also use a dedicated IP, but since your dedicated server includes a few IPs by default, you will not have to pay anything on top of the monthly fee for the machine itself.
