Varnish is a data caching platform, which is sometimes referred to as an HTTP reverse proxy. It is a web application accelerator that can boost the loading speed of a site by up to one thousand percent, 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 if 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 considerably faster, since the Varnish platform can serve information many times faster than any web server software. The end result is a considerably faster loading website, which leads to an immensely improved website browsing experience. In case any of the cached pages is updated on the actual Internet site, the content that Varnish saves in its system memory is updated as well, so the site visitors will never see out-of-date data.
Varnish in Shared Web Hosting
If you host your websites in a shared web hosting account with us, you will be able to add Varnish with a few clicks of the mouse through your Control Panel. The platform is offered as an optional upgrade with all our shared web hosting packages and you can choose how many sites will use it and the maximum amount of system memory that will be used 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 memory and they’re not linked directly to each other, so you can choose if you want plenty of memory for one single large-sized website or less memory for several smaller ones. You can unleash the full potential of the Varnish platform if the websites use a dedicated IP address. With the Control Panel, you can effortlessly start/restart/stop an instance, clear the cached files individually for each website which employs Varnish or see an elaborate log.
Varnish in Semi-dedicated Servers
The semi-dedicated servers offered by our company will allow you to use Varnish as soon as your new semi-dedicated account is active, as the platform comes by default. 64 MB of system memory will be allocated to Varnish the second your account is enabled, so you can make use of this workload balancing software as soon as you launch your website. If you are in need of more memory, you can add 32 MB at a time from the Upgrades section of the Hepsia Control Panel and it will be assigned to your semi-dedicated machine right away. You can also increase the number of the websites that use Varnish, or the so-called ‘instances’, which are not directly linked to the amount of memory that you use, which suggests that you will enjoy more flexibility. The caching platform will significantly lower the load on the server that your websites produce, so your visitors can enjoy fast-opening web pages. You’ll be able to manage the Varnish caching platform without efforts through the Control Panel using fast-access buttons. You’ll be able to start/delete any of the instances that you have, to delete the cached content associated with any of your sites or to check system logs.
Varnish in VPS Servers
We offer Varnish with all of the Hepsia-managed VPS servers, so if you order a VPS with this web hosting Control Panel, you’ll be able to take full advantage of the data caching platform at no extra cost. Varnish can utilize different amounts of memory for data caching purposes depending on the specific sever setup that you have chosen during the registration process, but nevertheless, this amount won’t be less than several hundred MB. This is quite enough to boost the work of a handful of resource-consuming sites, so the better web page load speeds and the less load on your server will be noticeable. The effect may not be visible instantly, as the Varnish platform will require a certain amount of time to cache the content that people request, but soon after you set it up, you will witness its full capacity. This caching platform will permit you to use a less powerful server and to pay less money to get the same performance you’d 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 will get Varnish at no additional fee and you will exert complete control over it via an extremely time and effort saving GUI – you’ll be able to start, to remove or to restart an instance, to view a detailed system log, to delete the cached data for any site and much more. The Varnish caching platform will have several gigabytes of memory at its disposal, so even if you host popular sites with multiple visitors, you’ll notice the tremendously better site loading speeds and the less load. This will become a fact shortly after you begin using the Varnish platform, as it will need some time to cache the web pages that users open. You can take full advantage of the platform’s capabilities if the sites that are using it use also a dedicated IP address, but considering the fact that your 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.
