Varnish
Learn precisely what Varnish is. Know much more about web accelerators and their function.
Varnish is a web application accelerator platform, which caches data for faster access. It is occasionally referred to as an HTTP reverse proxy as well and it interacts between a web server and a web browser. When a site visitor opens a given webpage, its content is requested by the Internet browser, and then the server processes this browser request and delivers the requested data. If Varnish is enabled for a certain website, it will cache its pages on the very first visit and in case the user accesses a cached page once again, the content will be delivered by the accelerator platform and not by the server. The boosted speed is a result of the significantly faster response time that the Varnish platform offers as compared with any server software. At the same time, this does not mean that the visitors will continue being served the exact same content again and again, as any modification on any of the web pages is reflected in the content that Varnish stores in its memory.

Varnish in Cloud Web Hosting
Varnish is available as an optional upgrade with each
cloud web hosting and if you would like to use it, you can add it to your hosting account through the Upgrades menu in your Hepsia hosting Control Panel. There are two separate features that can be upgraded – the number of instances and the memory. The first one refers to the number of the websites that you want to use Varnish for and the second one, which is available in increments of 32 MB, shows the total amount of content that the content caching platform can store at any given time. The Hepsia Control Panel’s user-friendly graphical interface will permit you to disable or to restart any instance, to see in-depth system logs or to erase the platform’s cache with just one mouse click. For best results, you can employ a dedicated IP address for the websites that will use the platform. With Varnish, your site will load much faster, which means more happy website visitors and potential customers.

Varnish in Semi-dedicated Servers
The Varnish platform is an essential part of the standard set of services that you will acquire in case you decide to host your Internet sites in a
semi-dedicated server account. You can configure it for any of your sites via our cutting-edge Hepsia Control Panel. The default amount of system memory that the Varnish caching platform can use to cache data is 64 megabytes, but if you decide that you want more, you can upgrade this amount from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, i.e. the number of the websites that can use this caching platform simultaneously. As these two things aren’t tied to each other, you can use a couple of sites with the default memory or you can get more memory in increments of 32 MB and use all of it for a single Internet site. The Varnish platform works best if you assign a dedicated IP to the sites that utilize its power. The Hepsia Control Panel will offer you an easy way of rebooting any instance. Furthermore, you will be able to clear the cached files with just one single mouse click.

Varnish in VPS Servers
You can use Varnish with each of our
VPS server plans at no additional cost, since the platform is pre-installed and is offered by default. The one and only precondition is that the VPS server must be ordered with the Hepsia Control Panel, through which you will be able to activate Varnish for any of your websites with just a few clicks. Each package comes with a different amount of system memory for content caching purposes, but you will have at least several hundred MB, which is sufficient even for multiple large websites. Soon after you activate the Varnish platform, it’ll begin caching the content that your visitors access, so you will notice the substantially faster page load times and the less load on your virtual server in no time. The Varnish caching platform will permit you to use a less costly Virtual Private Server, as you will not need that much power to sustain the correct operation of your Internet sites even if you run large-scale websites with multiple visitors. Maximum results are achieved if the sites which use the Varnish caching platform also use a dedicated IP address.

Varnish in Dedicated Servers
You can employ Varnish to enhance the loading speed of any site that’s hosted on a
dedicated server from our company if the Hepsia hosting Control Panel is installed on it. Not only will you get the platform ready for use at no additional charge, but you’ll also have full control over it via the Hepsia Control Panel’s simple-to-navigate GUI. It will take just a click to start or delete an instance or to delete the cached content for any site that is using Varnish and in case you’re more competent, you can also see the platform’s system logs. Varnish comes with at least 3 GB of virtual memory for content caching purposes, so even if you host many sites on your machine and they all use the Varnish platform, the improvement in their overall performance will be perceivable. You will just have to wait for a while till Varnish caches whatever content the visitors access on their end. The platform works best when the Internet sites use a dedicated IP address, but considering the fact that our dedicated servers come with 3 cost-free IP addresses, you will have everything you need.
