Varnish is a web app accelerator, which has been gaining a lot in popularity lately, as it can increase the loading speed of any site, at times even by one hundred percent, depending on the content. This tool is occasionally called an HTTP reverse proxy too and is used to reduce the overall load on the physical machine and to enhance the access speed for the website visitors. Every time a visitor opens a page on a given site, the browser request is processed by the web server and the requested info is delivered as a response. If Varnish is enabled, it caches the web pages that the visitor opens and in case any of them is accessed for a second time, it’s fetched by Varnish and not by the web server directly. The improvement in the performance is due to the fact that the accelerator handles the web requests substantially quicker than any web server, which leads to much faster browsing speeds for the visitors. If any data is edited in the meantime, the cached web pages will also be ‘refreshed’ the next time someone attempts to open them.

Varnish in Cloud Web Hosting

Varnish is available as an optional upgrade with each of our Linux cloud web hosting. You can add it to your hosting account through the Hepsia Control Panel, which is available with all shared packages and you’ll get an exceptionally user-friendly interface, which will grant you complete control over the content caching system. Using one-click quick-access controls, you can reboot or disable any of the instances, in other words – Varnish will no longer work for a particular website. You can also view a comprehensive system log file or erase the cache associated with any of the sites. When you add Varnish to your shared hosting plan, you will be able to select the maximum amount of memory that will be at your disposal for content caching purposes and the number of the sites that will use Varnish. You can always add more memory in increments of 32 MB and, for maximum performance, you can get a dedicated IP address for the websites that will use Varnish. This will permit you to get the most out of your sites and to have numerous pleased visitors.

Varnish in Semi-dedicated Hosting

The Varnish platform is included in the standard service set that you’ll receive when you decide to host your websites under a semi-dedicated server account. You can set it up for any of your Internet sites through our leading-edge Hepsia hosting Control Panel. The default memory that the Varnish platform can use to cache data is 64 megabytes, but in case you decide that you need more, you can upgrade this amount 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 features are not linked to each other, you can use several sites with the default amount of memory or you can add more memory in increments of 32 megabytes and use all of it for one single website. The Varnish caching platform works best if you allocate a dedicated IP to the sites that utilize its power. Hepsia will give you an easy way of rebooting any instance. What’s more, you’ll be able to delete the cached data with just a click.

Varnish in VPS Web Hosting

We provide Varnish with all Hepsia-managed Linux VPS web hosting, so if you get a VPS with this web hosting Control Panel, you will be able to make full use of the data caching platform at no extra charge. The Varnish platform can use different amounts of memory for caching purposes depending on the specific configuration that you have selected during the order process, but at any rate, this amount won’t be less than several hundred megabytes. This is more than enough to optimize the work of several different resource-demanding Internet sites, so the better web page loading speeds and the reduced load on the virtual machine will be noticeable. The effect may not be observable straight away, as the Varnish platform will require some time to cache the website content that users open, but soon after you set it up, you’ll perceive its full potential. This platform will permit you to use a less powerful Virtual Private Server and to pay less cash to get the very same performance you’d get with a more powerful virtual machine without Varnish.

Varnish in Dedicated Servers Hosting

All Linux dedicated servers hosting that are ordered with the custom-developed Hepsia website hosting Control Panel feature Varnish, which is among the pre-installed software platforms that you’ll get with the machine. The Varnish content caching platform can be set up and managed without effort via the Hepsia Control Panel’s user-friendly GUI and, with no more than one click, you can browse a comprehensive log, add or reboot an instance, clear the cache associated with any site and much more. Soon after you activate the Varnish platform for a given domain or sub-domain, it will begin caching the pages opened by the website visitors and once it has cached enough content, you’ll observe a tremendously better website performance in addition to a decreased load. With Varnish-dedicated memory starting at 3 GB, you will be able to use the platform for load balancing purposes even if you run multiple sites on the dedicated server.
