Varnish is a web accelerator tool, which has been gaining a lot of popularity in recent years, because it can increase the speed of any website, at times even by one hundred percent, depending on the content. This tool is sometimes called an HTTP reverse proxy too and is used to reduce the overall load on the server and to increase the access speed for the site visitors. Each time a visitor loads a page on a given site, the browser request is processed by the web server and the requested info is served as a response. If Varnish is enabled, it caches the web pages that the website visitor browses and if any of them is loaded again, it’s fetched by Varnish and not by the web server directly. The improvement in the overall performance is due to the fact that the accelerator handles the browser requests tremendously faster than any web server, which leads to much faster browsing speeds for the users. If any data is edited in the meantime, the cached pages will also be ‘refreshed’ the next time someone attempts to access them.

Varnish in Cloud Hosting

In case you host your Internet sites in a cloud hosting account with us, you’ll be able to add Varnish with a couple of mouse clicks via your hosting Control Panel. The caching platform is available as an optional upgrade with all our shared hosting plans and you can choose how many sites will use it and the maximum amount of system memory that will be available for the cached data. The two features that can be upgraded in the Control Panel’s Upgrades section are the number of instances and the amount of system memory and they’re not directly tied to each other, so you can decide whether you want a lot of memory for a single large website or less memory for multiple smaller ones. You can use the full potential of Varnish in case the websites use a dedicated IP address. With the Control Panel, you can quickly start/reboot/terminate an instance, clear the cached content individually for each site which uses the Varnish platform or view an in-depth log.

Varnish in Semi-dedicated Servers

The Varnish platform is part of the basic service set that you will obtain in case you decide to host your websites in a semi-dedicated server account. You can configure it for any of your Internet sites via our advanced Hepsia Control Panel. The default amount of memory that the Varnish platform can use to cache content is 64 MB, but if you decide that you need more, you can upgrade this amount of memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, i.e. the number of the sites that can use this platform at the same time. As these two features are not linked to each other, you can use a couple of Internet sites with the default memory or you can order more memory in increments of 32 megabytes and use all of it for one single web site. Varnish performs best when you assign a dedicated IP to the websites that utilize its power. The Hepsia Control Panel will offer you an easy way of rebooting any instance. Furthermore, you’ll be able to clear the cached content with just one click of the mouse.

Varnish in VPS Servers

We provide Varnish with all Hepsia-managed VPS servers, so if you acquire a VPS with this web hosting Control Panel, you’ll be able to use the content caching platform at no additional charge. The Varnish platform can use different amounts of memory for data caching purposes based on the specific setup that you’ve picked on the order form, but at any rate, this amount won’t be less than several hundred megabytes. This is quite enough to boost the performance of a number of resource-intensive websites, so the faster page loading speeds and the decreased load on your virtual server will be perceptible. The effect may not be observable right away, as the Varnish platform will need some time to cache the site content that visitors access, but shortly after you enable it, you will observe its full potential. This caching platform will allow you to use a less powerful server and to pay less money to get the exact same performance you would get with a more powerful virtual machine without Varnish.

Varnish in Dedicated Servers

In case you order a dedicated server with the Hepsia hosting Control Panel, you’ll get the Varnish caching platform at no additional cost and you will have complete control over it through an amazingly intuitive graphical interface – you’ll be able to start, to terminate or to restart an instance, to check an exhaustive system log, to delete the cached content associated with any site and much more. Varnish will have several gigabytes of memory at its disposal, so even if you run resource-hungry Internet sites with many visitors, you will notice the considerably better web page loading times and the reduced load on your dedicated server. This will become a fact shortly after you begin using the Varnish platform, as it will require some time to cache the site content that visitors request. You can take full advantage of the platform’s capacity if the sites that are using it also use a dedicated IP, but owing to the fact that your dedicated server includes a few IPs by default, you won’t have to pay anything on top of the monthly fee for the server itself.
