Varnish is a content caching platform, which is sometimes referred to as a caching HTTP reverse proxy. It’s a web application accelerator that can increase the load speed of a website by up to one thousand percent, based on its content. Whenever a visitor opens 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 accesses 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, as the Varnish platform can serve information many times faster than any web server software. The end result will be a considerably faster loading website, 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 system memory is ‘refreshed’ too, so the users won’t see old info.

Varnish in Cloud Website Hosting

Varnish is offered as an optional upgrade with each Linux cloud website hosting service and if you want to use it, you can add it to your hosting account via the Upgrades menu in your Hepsia Control Panel. There’re two different things that can be upgraded – the instances and the system memory. The first one pertains to the number of the sites that you would like to employ Varnish for, whereas the second, which is available in increments of 32 megabytes, refers to the maximum amount of data that the platform can cache at any particular moment. The Hepsia Control Panel’s intuitive interface will allow you to turn off or to restart any instance, to view in-depth logs or to get rid of the platform’s cache with just one click. For optimum results, you can use a dedicated IP for the websites that will use the platform. With Varnish, your site will load significantly faster, meaning more happy site users and prospective clients.

Varnish in Semi-dedicated Servers

The Varnish data caching platform is an essential part of the basic service set that you’ll receive if you decide to host your websites under 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 Varnish can use to cache data is 64 MB, but if you decide that you need more, you can upgrade this memory from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, i.e. the number of the sites that can use this platform at the same time. Since these two things are not bound to each other, you can use a couple of websites with the default amount of memory or you can get more memory in increments of 32 MB and use all of it for one single site. The Varnish caching platform performs best when you allocate a dedicated IP to the websites that utilize its power. Hepsia will provide you with a simple means of restarting any instance. On top of that, you’ll be able to clear the cached files with only one click.

Varnish in VPS Servers

We provide Varnish with all of the Hepsia-equipped Linux VPS servers, so if you acquire a server with this Control Panel, you will be able to make full use of the caching platform at no extra fee. The Varnish platform can use different amounts of system memory for data caching purposes depending on the very setup that you’ve picked during the signup process, but at any rate, this amount will not be less than several hundred MB. This is more than enough to boost the performance of several resource-absorbing sites, so the better site loading speeds and the reduced load on the Virtual Private Server will be discernible. The result may not be distinguishable immediately, as the Varnish platform will need some time to cache the site content that people browse, but soon after you activate it, you will feel its full potential. This caching platform will allow you to use a less powerful VPS server and to give less cash to get the exact same performance you would get with a more powerful machine without Varnish.

Varnish in Dedicated Servers

In case you order a dedicated server with the Hepsia Control Panel, you will obtain the Varnish caching platform at no extra fee and you will exert total control over it via a rather easy-to-work-with graphical interface – you’ll be able to start, to terminate or to reboot an instance, to check a comprehensive system log, to clear the cached data associated with any website and much more. The Varnish platform will have several gigabytes of virtual memory at its disposal, so even if you have popular Internet sites with an immense number of visitors, you’ll notice the tremendously better page loading times and the less load on your dedicated server. This will happen shortly after you start using the Varnish platform, as it will require a certain amount of time to cache the content that visitors request. You can get the most out of the platform’s capabilities in case the Internet sites that are using it also use a dedicated IP address, but owing to the fact that your server includes a few IP addresses by default, you will not have to pay anything on top of the monthly charge for the machine itself.
