Varnish is a web app accelerator platform, which caches data for quicker access. It is occasionally called an HTTP reverse proxy as well and it works between a web server and a browser. When a visitor opens a certain web page, the content is requested by the browser, and then the web server handles this browser request and returns the required content. If Varnish is activated for a site, it will cache the pages on the first request and in case the visitor opens a cached page again, the content will be delivered by the caching platform and not by the web server. The improved loading speed is a result of the considerably faster response speed that the Varnish platform offers as compared to any web server software. Of course, this doesn’t mean that the site visitors will continue seeing the very same content again and again, since any modification on any of the web pages is reflected in the content that Varnish keeps in its system memory.

Varnish in Web Hosting

In case you host your Internet sites in a web hosting account with us, you will be able to add Varnish with a couple of clicks from your hosting Control Panel. The platform is offered as an optional upgrade with all our shared hosting packages and you can choose how many websites will use it and the maximum amount of system memory that will be used for the cached content. The two features that can be upgraded in the Upgrades section of the Control Panel are the number of instances and the amount of system memory and they are not directly linked to each other, so you can decide if you want a lot of memory for a single large-size website or less memory for multiple smaller ones. You can take advantage of the full potential of Varnish in case the websites use a dedicated IP address. With the Control Panel, you can effortlessly start/restart/remove an instance, delete the cached files independently for each website that uses Varnish or check an in-depth system log file.

Varnish in Semi-dedicated Hosting

Varnish is an essential part of the basic service set that you will acquire when you choose to host your Internet sites under a semi-dedicated server account. You can enable it for any of your sites through our innovative Hepsia hosting Control Panel. The default amount of system memory that the Varnish platform can use to cache content is 64 megabytes, but if you decide that you need 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 simultaneously. Since these two features aren’t linked to each other, you can use several instances with the default amount of 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 assign a dedicated IP address to the websites that utilize its power. Hepsia will give you an easy way of rebooting any instance. Also, you’ll be able to delete the cached data with only one single click.

Varnish in VPS Hosting

You can use the load balancing capabilities of Varnish with each of our Linux VPS hosting if you choose Hepsia as your hosting Control Panel. The content caching platform is available by default and the system memory that it will be able to utilize to cache your website content is dependent upon the particular Virtual Private Server package that you’ve selected, but even with the lower-end packages, you will have no less than several hundred megabytes of memory at your disposal solely for caching purposes. This amount is sufficient to boost the performance of multiple Internet sites. It will take a little time for you to notice the results, since the Varnish platform caches the content that site visitors request, but shortly thereafter you will notice the significantly decreased load on your VPS and the enhanced site load speed. Varnish will permit you to use a lower-end Virtual Private Server plan for sites which would typically need a more costly web hosting solution.

Varnish in Dedicated Web Hosting

When you need the most powerful web hosting solution and you get any of the Linux dedicated web hosting that we are offering, you’ll be able to use the Varnish data caching platform to boost the overall performance of your websites at no additional cost on the condition that the dedicated machine is ordered with our avant-garde Hepsia Control Panel. Its intuitive graphical interface will enable you to keep an eye on system processes, to clear the cached files or to reboot any instance with one mouse click. The minimum amount of system memory that Varnish can employ to cache Internet site content is 3 GB, which is quite enough for a huge number of traffic-consuming websites, so your dedicated server will be able to cope with an enormous system load while your website visitors are enjoying a seamless browsing experience. Since your machine will include a number of dedicated IPs, you will be able to use Varnish’s maximum capacity.
