Varnish is a web application accelerator platform, which caches information for the sake of quicker access. It is sometimes called a caching HTTP reverse proxy as well and it interacts between a web server and an Internet browser. When a site visitor loads a particular web page, its content is requested by the web browser, and then the server handles this request and returns the necessary content. If Varnish is enabled for a given website, it will cache its pages on the first visit and if the visitor opens a cached page once more, the information will be delivered by the accelerator platform and not by the web server. The improved speed is an end result of the significantly faster response time that the Varnish platform offers as compared to any server software. Of course, this does not mean that the site visitors will continue seeing the exact same content over and over again, since any update on any of the pages is reflected in the content that the Varnish platform caches in its memory.

Varnish in Hosting

You can make use of Varnish’s potential and increase your websites’ loading speed irrespective of the hosting package that you have chosen and you can activate and set up the platform with several mouse clicks using the simple-to-work-with graphical interface offered by our innovative Hepsia hosting Control Panel. In the meantime, you’ll be able to choose two separate things – how many websites will use the Varnish caching platform, in other words – the number of instances, and how much information will be cached, i.e. the amount of memory. The latter is available in increments of 32 MB and is not linked to the number of instances, so you can add more instances with less memory and the other way around. In case you’ve got lots of content on a particular website and you get many site visitors, more memory will give you a better result. You may also consider using a dedicated IP for the sites that will use the Varnish caching platform. The Hepsia Control Panel will offer you simple one-click buttons for turning off or restarting any instance, for clearing the cache for any website and for seeing exhaustive system logs.

Varnish in Semi-dedicated Servers

The Varnish platform is part of the standard service set that you will obtain when you decide to host your websites under a semi-dedicated server account. You can enable it for any of your Internet sites through our leading-edge Hepsia hosting Control Panel. The default amount of memory that the Varnish caching platform can use to cache content is 64 megabytes, but if 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, i.e. the number of the Internet sites that can use this caching platform simultaneously. Since these two things aren’t tied to each other, you can use a few instances with the default memory or you can order more memory in increments of 32 MB and use all of it for a single website. The Varnish caching platform works best when you allocate a dedicated IP to the websites that utilize its power. The Hepsia Control Panel will offer you an easy means of restarting any instance. Also, you will be able to delete the cached data with only one single mouse click.

Varnish in VPS Servers

You can take advantage of Varnish with any of our VPS server plans at no additional fee, since the platform is pre-installed and is included by default. The only precondition is that the VPS must be ordered with the Hepsia hosting Control Panel, through which you will be able to activate Varnish for any of your websites with only a couple of clicks of the mouse. Each Virtual Private Server plan offers a different amount of memory for content caching purposes, but you’ll have at least several hundred megabytes, which is quite sufficient even for multiple resource-absorbing Internet sites. Shortly after you enable the Varnish platform, it’ll begin caching the content that your site visitors open, so you’ll notice the tremendously faster Internet site load times and the lowered load on your Virtual Private Server in no time. The Varnish platform will allow you to use a less expensive server, since you won’t require that much power to warrant the uninterrupted operation of your websites even if you manage large-size Internet sites with a lot of visitors. Optimal results are accomplished if the sites that use the Varnish caching platform use also a dedicated IP.

Varnish in Dedicated Servers

If you want the most powerful hosting solution and you acquire any of the dedicated servers offered by us, you can use the Varnish caching platform to optimize the performance of your websites at no additional fee on the condition that the dedicated machine is ordered with our avant-garde Hepsia Control Panel. Its user-friendly graphical interface will allow you to keep track of system processes, to clear the cached files or to reboot any instance with a click. The minimum amount of system memory that the platform can use to cache Internet site content is 3 gigabytes, which is quite enough for an enormous collection of traffic-consuming sites, so your dedicated server will be able to deal with a substantial load while your visitors are enjoying a seamless web browsing experience. Since your machine will come with a number of dedicated IPs, you’ll be able to make use of Varnish’s full potential.
