Learn exactly what Varnish is. Discover a lot more about web accelerators and their role.
Varnish is a content caching platform, which is occasionally referred to as a caching HTTP reverse proxy. It is a web app accelerator that can increase the loading speed of a site by up to one thousand percent, based on the content itself. Each 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 when the visitor opens it again. In this way, the web browser request from the visitor is not handled by the server and the web page will load considerably faster, since the Varnish platform can deliver information many times faster than any web server software. The end result is a substantially faster loading page, which means an immensely improved visitor experience. If any of the cached webpages is updated on the actual site, the content that Varnish stores in its memory is ‘refreshed’ as well, so the site visitors will not see out-of-date information.
Varnish in Shared Web Hosting
Varnish comes as an optional upgrade with each of our shared web hosting service
. You can add it to your account through the Hepsia hosting Control Panel, which comes with all shared hosting plans and you’ll get a quite easy-to-use GUI, which will give you complete control over the data caching platform. Using 1-click quick-access buttons, you can restart or remove any of the instances, i.e. Varnish will no longer be activated for a particular Internet site. You can also check a detailed log or clear the cache associated with any of the Internet sites. When you add Varnish to your shared hosting plan, you’ll be able to select the total amount of memory that will be at your disposal for data caching purposes and how many websites will use Varnish. You can always order more memory in increments of 32 MB and, for optimum performance, you can assign a dedicated IP to the websites that will use Varnish. This will permit you to get the most out of your Internet sites and to have a lot of gratified site visitors.
Varnish in Semi-dedicated Servers
The Varnish data caching platform is included in the standard set of services that you will acquire when you choose to host your websites in a semi-dedicated server
account. You can activate it for any of your sites via our innovative Hepsia Control Panel. The default system memory that the Varnish caching platform can use to cache data is 64 MB, but in case you decide that you want more, you can upgrade this amount of 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 platform simultaneously. As these two things aren’t bound to each other, you can use a couple of sites with the default amount of memory or you can get more memory in increments of 32 megabytes and use all of it for a single Internet site. The Varnish caching platform performs best when you get a dedicated IP for the sites that utilize its power. The Hepsia Control Panel will offer you an easy means of rebooting any instance. Also, you’ll be able to delete the cached content with only one mouse click.
Varnish in VPS Servers
We offer Varnish with all Hepsia-managed Linux VPS web hosting service
, so in case you get a server with this hosting Control Panel, you will be able to use the data caching platform at no additional charge. The Varnish platform can use different amounts of memory for content caching purposes depending on the very plan that you have selected on the order page, but at any rate, this amount won’t be less than several hundred MB. This is quite enough to improve the work of several different traffic-consuming websites, so the better web page browsing speeds and the reduced server load will be noticeable. The result may not be observable instantly, as the Varnish platform will require a certain amount of time to cache the website content that people open, but soon after you activate it, you’ll perceive its full potential. This platform will allow you to use a lower-end server and to pay less cash to get the exact same performance you would get with a higher-end virtual machine without Varnish.
Varnish in Dedicated Servers
You can use Varnish to enhance the speed of any site that is hosted on a dedicated server
from us when the Hepsia Control Panel is installed on the machine. Not only will you get the caching platform ready for use at no extra charge, but you will also exert full control over it via Hepsia’s easy-to-navigate graphical interface. It will take only one click to start or discontinue an instance or to delete the cached content associated with any Internet site that is using the Varnish platform and if you’re more trained, you can also browse the platform’s logs. Varnish comes with at least 3 GB of virtual memory for content caching purposes, so even in case you run many websites on your machine and they all use the platform, the difference in their performance will be perceivable. You’ll only need to wait for a little while until Varnish caches whatever pages the site visitors open on their end. The Varnish platform performs best if the sites use a dedicated IP, but due to the fact that our dedicated servers include 3 free IPs, you will have all that you need.
