Varnish is a data caching platform, which is occasionally called a caching HTTP reverse proxy. It is a website accelerator that can accelerate the speed of a site by up to 1000 percent, based on the content itself. Anytime a visitor accesses any page on a website that uses Varnish, the platform caches the page and delivers it instead of the web server if the visitor opens it again. Thus, the web browser request from the visitor is not handled by the web server and the page will load significantly faster, since Varnish can serve content many times faster than any server software. The result will be a considerably faster loading site, which leads to an improved browsing experience. When any of the cached pages is updated on the actual site, the information that Varnish caches in its memory is ‘refreshed’ too, so the users will not end up seeing old data.
Varnish in Hosting
You can take advantage of Varnish’s full potential and increase the speed of your sites regardless of the hosting
plan that you have chosen and you can activate and configure the platform with several clicks via the easy-to-use interface offered by our avant-garde Hepsia Control Panel. In the meantime, you will be able to select two different things – how many websites will employ Varnish, i.e. the number of instances, and how much information will be cached, in other words – the amount of system memory. The latter is available in increments of 32 MB and is not bound to the number of instances, so you can add more instances and less memory and vice versa. If you’ve got a lot of content on a particular website and you receive many visitors, more system memory will give you better results. You may also consider employing a dedicated IP for the websites that will use the Varnish platform. The Hepsia Control Panel will offer you simple 1-click controls for stopping or restarting any instance, for deleting the cache associated with any Internet site and for viewing detailed logs.
Varnish in Semi-dedicated Servers
Varnish is included in the basic set of services that you will acquire when you choose to host your Internet sites under a semi-dedicated server
account. You can activate it for any of your websites via our advanced Hepsia hosting Control Panel. The default system memory that the Varnish platform can use to cache data is 64 megabytes, but in case you decide that you need more, you can upgrade this memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, i.e. the number of the sites that can use this caching platform simultaneously. Since these two things are not bound to each other, you can use a few sites with the default memory or you can get more memory in increments of 32 megabytes and use all of it for a single web site. Varnish works best if you set a dedicated IP address for the Internet sites that utilize its power. Hepsia will give you an easy means of restarting any instance. Also, you’ll be able to clear the cached contents with just one mouse click.
Varnish in VPS Servers
You can take full advantage of the load balancing capabilities of Varnish with any of our VPS servers
in case you select Hepsia as your web hosting Control Panel. The Varnish caching platform comes by default and the amount of system memory that it will be able to use to cache your website content depends upon the given plan that you have selected, but even with the less powerful packages, you will have at least several hundred megabytes of memory at your disposal only for caching purposes. This amount is sufficient enough to improve the work of multiple sites. It’ll take some time for you to see the effects, since Varnish caches the content that site visitors request, but shortly after that you’ll notice the substantially decreased load on the virtual machine and the enhanced site browsing speed. The Varnish platform will permit you to use a less powerful VPS plan for websites which would normally need a more pricey web hosting solution.
Varnish in Dedicated Servers
If you need a more powerful website hosting solution and you purchase one of the dedicated servers
that we offer, you will be able to use the Varnish content caching platform to optimize the work of your sites at no additional charge on the condition that the dedicated server is ordered with our innovative Hepsia Control Panel. Its easy-to-work-with GUI will enable you to keep an eye on system processes, to clear the cached contents or to reboot any instance with one click. The minimal amount of system memory that the caching platform can use to cache site content is three gigabytes, which is more than enough for an enormous selection of resource-heavy websites, so your dedicated server will be able to handle a colossal load while your website visitors are having a smooth browsing experience. Since your dedicated machine will come with several dedicated IP addresses, you’ll be able to make use of Varnish’s maximum capacity.
