Varnish is a content caching platform, which is occasionally called a caching HTTP reverse proxy. It is a website accelerator that can boost the loading speed of a website by up to 1000 percent, based on the content itself. Anytime 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 accesses it again. Thus, the web browser request from the visitor is not handled by the server and the web page will load significantly faster, since the Varnish caching platform can serve information many times faster than any server software. The result will be a substantially faster loading page, which means an enormously improved browsing experience. If any of the cached web pages is updated on the actual website, the info that Varnish caches in its system memory is ‘refreshed’ too, so the visitors will not see old info.
Varnish in Shared Hosting
You can use Varnish’s full potential and accelerate your websites regardless of the shared hosting
package that you’ve selected and you can activate and configure the content caching platform with a few mouse clicks using the easy-to-use graphical interface offered by our advanced Hepsia hosting Control Panel. During the procedure, you’ll be able to choose two separate things – how many sites will employ the Varnish caching platform, i.e. the number of instances, and how much data will be cached, i.e. the amount of memory. The latter is available in increments of 32 megabytes and is not linked to the number of instances, so you can add more instances and less memory and vice versa. In case you’ve got lots of content on a given website and you get many site visitors, more system memory will give you better results. You may also consider using a dedicated IP for the sites that will use the Varnish caching platform. Hepsia will offer you easy one-click buttons for stopping or rebooting any instance, for erasing the cache for each site and for checking detailed logs.
Varnish in Semi-dedicated Servers
Varnish comes as standard with all semi-dedicated plans
that we are offering and you can use it for workload balancing purposes. It’s available in your Hepsia hosting Control Panel. The caching platform comes with 64 MB of system memory for cached data storing purposes and you can use it with any site that you host in your account. In case you need more than that, you can increase the memory allocation. The memory itself is offered in increments of 32 MB through the Upgrades section of the Control Panel. The exact same section will enable you to add more instances as well, in case you would like to use the Varnish platform with more websites. The two things can be added separately – you can cache the content of one popular Internet site or use several different websites with the default memory. You can get the most out of the Varnish platform if you’ve got a dedicated IP and you can get one with your semi-dedicated server plan as well. Hepsia will grant you total control over the platform and, with no more than one click, you’ll be able to delete the cached content, to see a system log or to reboot an instance.
Varnish in VPS Servers
We provide Varnish with all of the Hepsia-managed VPS web hosting plans
, so if you obtain a VPS with this Control Panel, you’ll be able to make the most of the caching platform at no extra cost. Varnish can utilize different amounts of system memory for caching purposes depending on the specific Virtual Private Server plan that you’ve selected during the signup process, but in any case, this amount won’t be less than several hundred MB. This is quite enough to improve the performance of a handful of traffic-hungry sites, so the better site browsing speeds and the less load on your virtual machine will be perceivable. The effect may not be apparent instantly, since the Varnish platform will require a certain amount of time to cache the site content that users browse, but soon after you activate it, you’ll perceive its full potential. This platform will permit you to use a lower-end VPS and to pay less money to get the exact same performance you would get with a higher-end machine without Varnish.
Varnish in Dedicated Servers
If you want a more powerful web hosting solution and you buy one of the dedicated web hosting plans
that we’re offering, you will be able to use Varnish to optimize the overall performance of your sites at no additional charge on the condition that the dedicated machine is ordered with our advanced Hepsia Control Panel. Its simple-to-work-with graphical interface will permit you to keep an eye on system processes, to clear the cached content or to restart any instance with one single click of the mouse. The minimal amount of memory that Varnish can use to cache Internet site content is 3 GB, which is quite enough for an immense collection of resource-absorbing Internet sites, so your server will be able to handle a massive load while your site visitors are having a seamless browsing experience. As your dedicated server will come with several dedicated IPs, you’ll be able to make use of Varnish’s maximum potential.
