Varnish is a web application accelerator tool, which has been gaining a lot of popularity lately, as it can increase the loading speed of any site, at times even by 100%, based on the content. This tool is sometimes referred to as a caching HTTP reverse proxy too and is used to decrease the overall server load and to enhance the browsing speed for the website visitors. Every time a visitor opens a page on a given Internet site, the browser request is taken care of by the web server and the requested content is served as a response. If the Varnish accelerator is enabled, it caches the pages that the website visitor browses and if any of them is opened once again, it is fetched by Varnish and not by the server directly. The performance increase is due to the fact that the accelerator processes the browser requests tremendously quicker than any web server, which leads to much faster browsing speeds for the visitors. If any data is updated meanwhile, the cached webpages will also be ‘refreshed’ the next time somebody attempts to access them.

Varnish in Cloud Web Hosting

Varnish is offered as an optional upgrade with all our cloud web hosting. You can add it to your web hosting account from the Hepsia Control Panel, which is available with all shared plans and you will get an amazingly user-friendly interface, which will give you complete control over the content caching platform. Using 1-click fast-access controls, you can reboot or delete any of the instances, i.e. Varnish will no longer work for a certain Internet site. You can also see a detailed system log or delete the cache for any of the sites. When you add Varnish to your shared web hosting plan, you’ll be able to choose the total amount of system memory that will be at your disposal for data caching purposes and the number of the websites that will use Varnish. You can always get more memory in increments of 32 MB and, for top performance, you can set a dedicated IP address for the websites that will use Varnish. This will enable you to take full advantage of your sites and to have a lot of gratified site visitors.

Varnish in Semi-dedicated Hosting

The Varnish platform is included in the standard service set that you’ll obtain in case you choose to host your websites under a semi-dedicated server account. You can enable it for any of your Internet sites through our next-gen Hepsia hosting Control Panel. The default amount of system memory that Varnish can use to cache data is 64 megabytes, but in case you decide that you want more, you can upgrade this memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, in other words – the number of the websites that can use this caching platform at the same time. As these two features are not linked to each other, you can use a couple of instances with the default amount of memory or you can get more memory in increments of 32 MB and use all of it for a single website. Varnish 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. Also, you will be able to delete the cached files with just one mouse click.

Varnish in VPS

We offer Varnish with all Hepsia-equipped VPS packages, so if you obtain a server with this web hosting Control Panel, you will be able to make use of the data caching platform at no additional charge. Varnish can use different amounts of memory for caching purposes based on the specific server configuration that you’ve chosen during the order process, but at any rate, this amount won’t be less than several hundred MB. This is quite enough to boost the overall performance of a number of traffic-heavy websites, so the faster page browsing speeds and the decreased load on the virtual machine will be discernible. The effect may not be distinguishable momentarily, as the Varnish platform will require a certain amount of time to cache the website content that people open, but soon after you enable it, you will observe its full capacity. This caching platform will permit you to use a less powerful Virtual Private Server and to give less money to get the same performance you’d get with a higher-end machine without Varnish.

Varnish in Dedicated Hosting

In case you order a dedicated server with the Hepsia Control Panel, you’ll obtain the Varnish data caching platform at no extra charge and you will have total control over it via an incredibly simple-to-use graphical interface – you will be able to start, to delete or to restart an instance, to view an exhaustive system log, to delete the cached content associated with any Internet site and much, much more. Varnish will have several gigabytes of memory at its disposal, so even if you have resource-hungry sites with a vast number of visitors, you’ll notice the considerably faster website loading speeds and the reduced load. This will happen shortly after you begin using the Varnish platform, since it will require some time to cache the website content that people access. You can make the most of the platform’s capabilities if the websites that are using it also use a dedicated IP address, but considering the fact that your dedicated server comes with a couple of IP addresses by default, you won’t need to pay anything on top of your monthly charge for the server itself.
