Varnish is a data caching platform, which is occasionally called an HTTP reverse proxy. It is a web accelerator that can improve the speed of a website by up to one thousand percent, based on its content. Every time a visitor accesses 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. Thus, the browser request from the visitor is not handled by the web server and the page will open tremendously faster, since the Varnish platform can serve content many times faster than any server software. The end result is a substantially faster loading site, which leads to an enormously improved visitor experience. If any of the cached webpages is updated on the actual site, the information that Varnish keeps in its memory is ‘refreshed’ as well, so the visitors will never see outdated data.
Varnish in Website Hosting
You can use Varnish’s potential and accelerate the loading speed of your websites irrespective of the website hosting package that you’ve picked and you can add and set up the data caching platform with a few clicks from the easy-to-work-with interface offered by our advanced Hepsia hosting Control Panel. In the meantime, you will be able to select two separate things – how many sites will employ the Varnish caching platform, in other words – the number of instances, and how much content will be cached, i.e. the amount of system memory. The latter is offered in increments of 32 MB and is not bound to the number of instances, so you can order more instances and less memory and vice versa. In case you have plenty of content on a given website and you win many website visitors, more memory will guarantee you better results. You may also consider using a dedicated IP address for the Internet sites that will use the Varnish caching platform. The Hepsia Control Panel will provide you with simple 1-click buttons for turning off or restarting any instance, for clearing the cache associated with each site and for checking detailed logs.
Varnish in Semi-dedicated Servers
The semi-dedicated service offered by us will allow you to use Varnish as soon as your brand new account has been created, since the data caching platform comes by default. 64 MB of system memory will be assigned to Varnish the second your account is activated, so you can use this load balancing software once your site has been published to the web. If you need more system memory, you can get 32 MB at a time from the Hepsia Control Panel’s Upgrades section and it will be allocated to your semi-dedicated server in an instant. You can also increase the number of the websites that use Varnish, or the so-called ‘instances’, which are not linked directly to the amount of system memory that you use, which goes to say that you will enjoy more freedom. The Varnish platform will substantially reduce the load on the semi-dedicated server caused by your sites, so your site visitors can enjoy fast-loading web pages. You’ll be able to manage the Varnish platform with no effort via your Control Panel using quick-access buttons. You’ll be able to start/discontinue any of the instances that you have, to delete the cached data for any of your Internet sites or to check system log files.
Varnish in VPS Servers
We provide Varnish with all Hepsia-managed Linux VPS service, so in case you obtain a server with this web hosting Control Panel, you will be able to use the content caching platform at no additional charge. The Varnish platform can use different amounts of memory for content caching purposes depending on the particular server configuration that you’ve selected on the order form, but at any rate, this amount will not be less than several hundred megabytes. This is more than enough to improve the overall performance of several different busy Internet sites, so the faster page loading speeds and the less load on your server will be discernible. The result may not be obvious instantly, as the Varnish platform will need some time to cache the site content that users access, but soon after you enable it, you will witness its full capacity. This platform will allow you to use a lower-end VPS and to give less money to get the exact same performance you would get with a higher-end virtual machine without Varnish.
Varnish in Dedicated Servers
All Linux dedicated servers which are ordered with the custom Hepsia hosting Control Panel include Varnish, which is among the pre-installed software platforms that you’ll get with the server. The Varnish content caching platform can be activated and managed without any effort through Hepsia’s easy-to-use graphical interface and, with no more than one mouse click, you can check a detailed log, create or reboot an instance, delete the cached data for any site and much more. Shortly after you activate the Varnish platform for a given domain or subdomain, it will begin caching the webpages accessed by your website visitors and once it has cached enough content, you’ll witness a considerably better website performance in addition to a reduced load on the server. With Varnish-dedicated system memory starting at three gigabytes, you will be able to use the software platform for workload distribution purposes even if you host a lot of sites on the dedicated machine.
