Varnish is a web app accelerator platform, which caches data for faster access. It’s occasionally called an HTTP reverse proxy as well and it works between a web server and its users. When a visitor loads a specific webpage, the content is requested by the web browser, and then the web server handles this browser request and returns the requested content. If Varnish is enabled for a site, it will cache its pages at the very first visit and in case the user visits a cached page once again, the information will be delivered by the accelerator platform and not by the web server. The increased speed is an end result of the considerably faster response speed that the Varnish platform offers as compared to any web server software. At the same time, this does not mean that the site visitors will continue seeing the very same content over and over again, as any change on any of the web pages is reflected in the content that Varnish caches in its system memory.

Varnish in Cloud Hosting

In case you host your websites under a cloud hosting account with our company, you’ll be able to add Varnish with several mouse clicks through your hosting Control Panel. The content caching platform is available as an optional upgrade with all our hosting packages and you can select how many sites will use it and the maximum storage space 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’re not directly linked to each other, so you can decide whether you need a lot of memory for one single large-sized website or less memory for multiple smaller ones. You can make use of the full potential of the Varnish caching platform in case the sites use a dedicated IP. Using the Control Panel, you can easily start/reboot/discontinue an instance, clear the cached files independently for each site which uses the Varnish platform or view a detailed system log file.

Varnish in Semi-dedicated Hosting

The Varnish content caching platform is part of the basic service set that you will obtain in case you decide to host your Internet sites in a semi-dedicated server account. You can set it up for any of your sites via our next-generation Hepsia Control Panel. The default amount of system memory that Varnish can use to cache data is 64 megabytes, but in case you decide that you need more, you can upgrade this amount 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 platform simultaneously. As these two things aren’t bound to each other, you can use a few sites with the default memory or you can order more memory in increments of 32 megabytes and use all of it for a single web site. The Varnish caching platform performs best when you set a dedicated IP for the Internet sites that utilize its power. The Hepsia Control Panel will give you an easy means of restarting any instance. In addition, you will be able to clear the cached contents with just one single mouse click.

Varnish in VPS

You can take advantage of Varnish with all our virtual private server plans at no extra charge, since the content caching platform is pre-installed and is available by default. The one and only condition is that the VPS must be ordered with the Hepsia Control Panel, through which you’ll be able to activate Varnish for any of your sites with only a couple of mouse clicks. Each plan includes a different amount of system memory for caching purposes, but you’ll have minimum several hundred MB, which is sufficient enough even for several large-size websites. Soon after you set up the Varnish platform, it’ll start caching the content that your website visitors request, so you’ll notice the significantly faster web page load speeds and the decreased load very soon. Varnish will allow you to use a less high-priced VPS server, as you won’t require that many resources to sustain the correct operation of your Internet sites even if you’ve got traffic-heavy Internet sites with a lot of visitors. Optimum results are accomplished if the sites that use the Varnish platform also use a dedicated IP address.

Varnish in Dedicated Hosting

In case you order a dedicated server with the Hepsia Control Panel, you will acquire Varnish at no additional fee and you will exert complete control over it via an exceptionally easy-to-use graphical interface – you will be able to start, to delete or to restart an instance, to check a comprehensive log, to delete the cache for any website and much, much more. The Varnish caching platform will have several gigabytes of memory at its disposal, so even if you manage large-size websites with plenty of visitors, you will notice the tremendously faster web page load times and the less load. This will happen shortly after you begin using Varnish, since it will need a certain amount of time to cache the website content that users request. You can get the most out of the platform’s capability in case the Internet sites that are using it also use a dedicated IP address, but owing to the fact that your dedicated server comes with a few IPs by default, you will not have to pay anything on top of the monthly charge for the server itself.
