Varnish is a website accelerator platform, which caches content 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 visitor loads a particular webpage, its content is requested by the browser, and then the server processes this browser request and returns the required data. If Varnish is enabled for a given site, it will cache the pages at the first request and in case the user visits a cached page for a second time, the data will be delivered by the accelerator platform and not by the web server. The boosted loading speed is a result of the considerably faster response time that the Varnish platform offers compared to any server software. Of course, this does not mean that the visitors will continue seeing the exact same content over and over again, since any change on any of the web pages is reflected in the content that the Varnish platform caches in its memory.

Varnish in Cloud Web Hosting

In case you host your sites under a cloud web hosting account with our company, you will be able to add Varnish with a few mouse clicks through your hosting Control Panel. The data caching platform is available as an optional upgrade with all our hosting packages and you can select the number of the websites that will use it and the maximum storage space that will be available for the cached content. The two upgradeable features in the Control Panel’s Upgrades section are the amount of memory and the number of instances and they’re not directly tied to each other, so you can decide if you want lots of memory for one large site or less memory for multiple smaller ones. You can take advantage of the full potential of the Varnish caching platform in case the websites use a dedicated IP. With the hosting Control Panel, you can quickly start/restart/disable an instance, delete the cached files independently for each website which uses the Varnish platform or check a detailed log.

Varnish in Semi-dedicated Servers

The semi-dedicated servers that we’re offering will permit you to use Varnish once your brand new semi-dedicated account is active, as the caching platform is available by default. 64 MB of system memory will be assigned to Varnish the second your account is enabled, so you can make use of this workload balancing software once your website has been launched. In case you are in need of more memory, you can order 32 megabytes at a time from the Hepsia hosting Control Panel’s Upgrades section and it will be assigned to your semi-dedicated machine instantly. You can also increase the number of the Internet sites that employ Varnish, or the so-called ‘instances’, which are not directly linked to the amount of system memory that you use, which suggests that you’ll have more freedom. The Varnish platform will significantly reduce the server load that your sites produce, so your site visitors can enjoy fast-opening pages. You’ll be able to manage the Varnish caching platform with ease through your Hepsia Control Panel using fast-access buttons. You will be able to start/cancel any of the instances that you have, to delete the cached data associated with any of your websites or to view system logs.

Varnish in VPS Servers

We provide Varnish with all Hepsia-managed VPS servers, so if you purchase a VPS with this Control Panel, you will be able to make full use of the data caching platform at no additional cost. Varnish can use different amounts of system memory for content caching purposes based on the very setup that you have chosen during the VPS order process, but in any case, this amount will not be less than several hundred megabytes. This is quite enough to optimize the performance of several different resource-demanding sites, so the better site browsing speeds and the less load on the VPS server will be perceptible. The effect may not be obvious immediately, as Varnish will require some time to cache the content that visitors browse, but soon after you enable it, you will witness its full capacity. This platform will allow you to use a less powerful Virtual Private Server and to pay less money to get the exact same performance you’d get with a more powerful machine without Varnish.

Varnish in Dedicated Servers

All Linux dedicated service that are ordered with the custom-developed Hepsia website hosting Control Panel feature Varnish, which is among the pre-installed platforms that you’ll get with the dedicated server. The Varnish content caching platform can be set up and administered without efforts via Hepsia’s time and effort saving interface and, with no more than one single click, you can check an exhaustive log, add or reboot an instance, delete the cached files for any website and much, much more. Shortly after you activate Varnish for a specific domain or subdomain, it will start caching the webpages accessed by the site visitors and as soon as it has cached enough web content, you’ll observe a substantially faster site performance as well as a lowered load on the server. With Varnish-dedicated system memory starting at 3 gigabytes, you’ll be able to use the platform for load balancing purposes even if you host plenty of sites on your machine.
