Varnish is a data caching platform, which is sometimes called an HTTP reverse proxy. It’s a web application accelerator tool that can improve the loading speed of a site by up to 1000%, based on the content itself. Each time a visitor opens any page on a site that uses Varnish, the platform caches the page and delivers it instead of the web server when the visitor opens it again. In this way, the web browser request from the visitor is not processed by the server and the web page will open much faster, as the Varnish caching platform can deliver content many times faster than any web server software. The end result will be a substantially faster loading website, which means an improved visitor experience. If any of the cached web pages is updated on the live website, the info that Varnish caches in its memory is ‘refreshed’ as well, so the site visitors will not end up seeing outdated info.
Varnish in Hosting
Varnish comes as an optional upgrade with each of our Linux hosting plans. You can add it to your web hosting account through the Hepsia Control Panel, which is offered with all shared web hosting plans and you will get an exceptionally easy-to-work-with interface, which will give you complete control over the caching platform. Using 1-click quick-access buttons, you can restart or cancel any of the instances, i.e. Varnish will no longer be enabled for a particular Internet site. You can also see an in-depth log file or delete the cache for any of the sites. When you add Varnish to your web hosting plan, you’ll be able to choose the total amount of system memory that will be available to you for content caching purposes and how many sites will use Varnish. You can always get more memory in increments of 32 megabytes and, for maximum performance, you can get a dedicated IP address for the sites that will use Varnish. This will allow you to take full advantage of your websites and to have a lot of satisfied visitors.
Varnish in Semi-dedicated Servers
All our semi-dedicated servers come with Varnish by default, so you can make use of the web app accelerator tool and increase the loading speed of any site that you host on our semi-dedicated servers. You’ll get 64 megabytes of system memory particularly for Varnish at no extra charge and you will be able to create an instance with no more than a couple of clicks of the mouse via the Hepsia Control Panel, which comes with the semi-dedicated server plans. In case you want more memory, the latter is offered in increments of 32 megabytes through the Control Panel’s Upgrades section and it will be at your disposal momentarily. You can also add more instances as a separate upgrade, so you can choose whether a lot of content will be cached for one site or if the available memory will be used by several sites. Hepsia will allow you to restart or to terminate any instance, to see the system log file associated with it or to delete the cached files using 1-click controls. To take full advantage of the Varnish accelerator, you can allocate a dedicated IP address to the Internet sites which will employ it.
Varnish in VPS Servers
You can take advantage of Varnish with each of our VPS server plans at no additional cost, as the data caching platform is pre-installed and is offered by default. The only prerequisite is that the virtual server must come with the Hepsia Control Panel, via which you will be able to activate Varnish for any of your Internet sites with only a few clicks. Each plan includes a different amount of memory for content caching purposes, but you’ll have minimum several hundred MB, which is sufficient enough even for several traffic-heavy Internet sites. Shortly after you activate Varnish, it’ll start caching the content that your site visitors request, so you’ll notice the tremendously faster website load speeds and the reduced load on the virtual machine in no time. The Varnish caching platform will permit you to use a less costly virtual machine, since you will not require that much power to ensure the uninterrupted operation of your websites even if you’ve got larger Internet sites with numerous visitors. Best results are accomplished if the websites that use Varnish use also a dedicated IP address.
Varnish in Dedicated Servers
If you need a more powerful web hosting solution and you acquire one of the dedicated web hosting plans that we offer, you can use the Varnish content caching platform to enhance the performance of your sites at no extra charge as long as the server is ordered with our next-generation Hepsia Control Panel. Its easy-to-work-with graphical interface will allow you to monitor platform processes, to clear the cached content or to restart any instance with one click. The minimal amount of memory that the Varnish caching platform can employ to cache website content is 3 GB, which is more than enough for a large collection of resource-requiring sites, so your dedicated server will be able to deal with an immense system load while your visitors are having a seamless browsing experience. As your server will include several different dedicated IPs, you’ll be able to use Varnish’s full capacity.
