Varnish is a website accelerator platform, which caches data for faster access. It is sometimes referred to as an HTTP reverse proxy too and it interacts between a web server and a browser. When a website visitor accesses a given webpage, its content is requested by the web browser, and then the web server handles this browser request and delivers the requested information. If Varnish is enabled for a website, it will cache its pages on the very first visit and in case the visitor opens a cached page once again, the info will be delivered by the accelerator platform and not by the web server. The boosted load speed is an end result of the substantially faster response time that the Varnish platform offers compared with any server software. At the same time, this doesn’t mean that the visitors will keep seeing the very same content again and again, as any modification on any of the web pages is reflected in the content that the Varnish platform keeps in its memory.

Varnish in Cloud Web Hosting

Varnish is offered as an optional upgrade with each cloud web hosting service and if you’d like to use it, you can add it to your shared hosting account using the Upgrades menu in your Hepsia Control Panel. There’re two different things that can be upgraded – the instances and the system memory. The first one refers to the number of the Internet sites that you want to employ Varnish for and the second one, which is offered in increments of 32 megabytes, displays the maximum amount of data that the data caching platform can store at any particular moment. Hepsia’s time and effort saving graphical interface will allow you to cancel or to restart any instance, to view in-depth system logs or to clear the platform’s cache with just click of the mouse. For best results, you can employ a dedicated IP for the sites that will use the caching platform. With Varnish, your Internet site will load substantially faster, meaning more satisfied website visitors and potential customers.

Varnish in Semi-dedicated Servers

The Varnish content caching platform is an essential part of the standard service set that you’ll obtain when you decide to host your Internet sites under a semi-dedicated server account. You can activate it for any of your websites via our next-generation Hepsia Control Panel. The default amount of memory that the Varnish caching platform can use to cache data is 64 MB, but if you decide that you want more, you can upgrade this amount of 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. As these two things aren’t linked to each other, you can use a few instances with the default amount of memory or you can order more memory in increments of 32 MB and use all of it for one single site. Varnish works best if you set a dedicated IP address for the Internet sites that utilize its power. Hepsia will give you an easy means of restarting any instance. What’s more, you will be able to clear the cached files with only one single click of the mouse.

Varnish in VPS Servers

You can use the load balancing capabilities of Varnish with each of our Linux VPS service if you pick Hepsia as your Control Panel. The data caching platform comes by default and the amount of system memory that it will be able to utilize to cache the content of your websites is dependent upon the specific VPS package that you’ve chosen, but even with the less powerful plans, you will have at least several hundred megabytes of system memory at your disposal solely for data caching purposes. This amount is enough to improve the overall performance of numerous Internet sites. It’ll take a little time for you to distinguish the results, since Varnish caches the content that website visitors browse, but soon thereafter you will notice the substantially decreased load on the Virtual Private Server and the accelerated site loading speed. Varnish will permit you to use a less powerful Virtual Private Server package for sites that would typically need a more expensive web hosting service.

Varnish in Dedicated Servers

If you want a powerful hosting solution and you get any of the dedicated service offered by us, you will be able to use the Varnish caching platform to enhance the work of your Internet sites at no additional cost on the condition that the dedicated machine is ordered with our avant-garde Hepsia Control Panel. Its easy-to-use graphical interface will allow you to keep track of platform processes, to clear the cached contents or to restart any instance with one single mouse click. The minimum amount of system memory that the Varnish platform can employ to cache Internet site content is three gigabytes, which is more than enough for a large collection of resource-absorbing sites, so your dedicated server will be able to deal with a gigantic load while your visitors are enjoying a seamless web browsing experience. As your machine will include several different dedicated IP addresses, you will be able to use Varnish’s maximum capacity.
