Varnish is a data caching platform, which is sometimes called an HTTP reverse proxy. It is a web application accelerator that can improve the load speed of a website by up to one thousand percent, depending on the content itself. Whenever a visitor accesses any page on a site that uses Varnish, the platform caches the page and delivers it instead of the web server in case the visitor opens it again. In this way, the browser request from the visitor is not handled by the web server and the page will load substantially faster, since Varnish can serve content many times faster than any server software. The end result will be a considerably faster loading page, which means an enormously improved website browsing experience. When any of the cached web pages is updated on the actual website, the data that Varnish keeps in its memory is ‘refreshed’ too, so the site visitors will never end up seeing out-of-date info.
Varnish in Hosting
You can take advantage of Varnish’s potential and increase the load speed of your websites irrespective of the hosting package that you’ve chosen and you can enable and configure the data caching platform with several clicks of the mouse from the user-friendly graphical interface offered by our next-generation Hepsia hosting Control Panel. In the meantime, you will be able to select two different things – how many Internet sites will use the Varnish platform, i.e. the number of instances, and how much information will be cached, in other words – the amount of memory. The latter is available in increments of 32 megabytes and is not tied to the number of instances, so you can order more instances with less memory and the other way around. If you’ve got plenty of content on a particular site and you win plenty of website visitors, more memory will give you better results. You may also consider employing a dedicated IP address for the Internet sites that will use the Varnish caching platform. The Hepsia Control Panel will offer you simple one-click buttons for removing or rebooting any instance, for clearing the cache for any site and for checking in-depth logs.
Varnish in Semi-dedicated Servers
Varnish is a feature, which comes by default with all semi-dedicated servers offered by us and you can use it for load balancing purposes. It’s available in your Hepsia Control Panel. The Varnish content caching platform comes with 64 MB of system memory for cached data storing purposes and you can employ it with any Internet site that you host in the semi-dedicated account. If you are in need of more, you can increase the memory allocation. The memory itself is available in increments of 32 megabytes in the Upgrades section of the Control Panel. The exact same section will allow you to create more instances too, if you’d like to use Varnish with multiple Internet sites. The two things can be added independently – you can cache the content of one traffic-heavy Internet site or use a number of websites with the default memory allowance. You can take full advantage of Varnish if you have a dedicated IP and you can order one with your semi-dedicated package as well. The Hepsia Control Panel will give you total control over the caching platform and, with no more than one click of the mouse, you’ll be able to delete the cached data, to view a system log or to reboot an instance.
Varnish in VPS Servers
We offer Varnish with all Hepsia-managed Linux VPS web hosting plans, so in case you purchase a VPS with this web hosting Control Panel, you will be able to make full use of the caching platform at no additional cost. The Varnish platform can utilize different amounts of system memory for data caching purposes based on the particular package that you’ve selected during the subscription process, but nevertheless, this amount won’t be less than several hundred MB. This is quite enough to boost the overall performance of a handful of large-scale sites, so the better website load speeds and the less load will be perceivable. The result may not be visible momentarily, since Varnish will need a certain amount of time to cache the content that visitors access, but soon after you enable it, you’ll perceive its full capacity. This caching platform will allow you to use a less powerful VPS and to give less money to get the exact same performance you would get with a more powerful machine without Varnish.
Varnish in Dedicated Servers
If you order a dedicated server with the Hepsia hosting Control Panel, you’ll get Varnish at no additional charge and you will have complete control over it through an extremely user-friendly interface – you’ll be able to start, to delete or to restart an instance, to see a comprehensive log, to clear the cached content for any site and much more. Varnish will have several GB of memory at its disposal, so even if you host resource-requiring websites with many visitors, you will notice the tremendously faster site loading speeds and the lowered server load. This will become a fact shortly after you start using Varnish, since it will need some time to cache the website content that people access. You can make the most of the platform’s capacity in case the sites that are using it use also a dedicated IP address, but due to the fact that your dedicated server comes with a couple of IP addresses by default, you will not need to pay anything on top of the monthly fee for the server itself.
