Varnish is a web application accelerator tool, which has been gaining a lot in popularity in recent years, because it can increase the load speed of any site, at times even by 100%, based on the content itself. This tool is occasionally called a caching HTTP reverse proxy as well and is used to decrease the overall load on the physical machine and to improve the browsing speed for the site visitors. Whenever a visitor opens a page on a certain website, the web browser request is taken care of by the web server and the requested content is sent as a reply. If Varnish is enabled, it caches the pages that the website visitor browses and if any of them is accessed once again, it’s served by Varnish and not by the web server directly. The improvement in the overall performance comes from the fact that the accelerator processes the web requests tremendously faster than any web server, which results in much faster browsing speeds for the visitors. In case any content is updated in the meantime, the cached webpages will also be ‘refreshed’ the next time someone opens them.

Varnish in Cloud Web Hosting

We offer Varnish as an optional upgrade with each cloud web hosting and if you want to use it, you can add it to your website hosting account via the Upgrades section in your Hepsia hosting Control Panel. There’re two separate features that can be upgraded – the instances and the memory. The first one pertains to the number of the sites that you would like to use Varnish for and the second one, which is offered in increments of 32 megabytes, pertains to the total amount of data that the data caching platform can store at any given moment. Hepsia’s easy-to-use graphical interface will permit you to delete or to restart any instance, to see elaborate logs or to clear the platform’s cache with just one click. For optimum results, you can use a dedicated IP for the Internet sites that will use the caching platform. With Varnish, your Internet site will load substantially faster, meaning more happy site visitors and potential clients.

Varnish in Semi-dedicated Servers

The Varnish platform is included in the default set of services that you will get in case you choose to host your websites in a semi-dedicated server account. You can enable it for any of your sites via our avant-garde Hepsia Control Panel. The default amount of 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 Internet sites that can use this caching platform simultaneously. As these two things are not linked to each other, you can use several instances with the default amount of memory or you can get more memory in increments of 32 megabytes and use all of it for one single Internet site. The Varnish caching platform performs best when you get a dedicated IP address for the sites that utilize its power. Hepsia will provide you with a simple means of restarting any instance. Also, you’ll be able to clear the cached files with just a click.

Varnish in VPS Servers

You can take advantage of Varnish with all our VPS server plans at no extra cost, since the content caching platform is pre-installed and is included by default. The sole condition is that the server must be ordered with the Hepsia hosting Control Panel, via which you’ll be able to activate Varnish for any of your sites with only a few mouse clicks. Each VPS package includes a different amount of memory for data caching purposes, but you’ll have minimum several hundred MB, which is enough even for several large Internet sites. Soon after you activate the Varnish platform, it will start caching the content that your site visitors open, so you’ll notice the tremendously better site loading times and the reduced load on the VPS very soon. The caching platform will allow you to use a less costly virtual server, as you will not need that much power to ensure the proper operation of your sites even if you run heavy-traffic Internet sites with a lot of visitors. Optimal results are achieved if the Internet sites that use the Varnish platform use also a dedicated IP address.

Varnish in Dedicated Servers

All dedicated servers that are ordered with the in-house built Hepsia web hosting Control Panel come with Varnish, which is one of the pre-installed platforms that you will get with the dedicated machine. The Varnish platform can be configured and managed without efforts via the Hepsia Control Panel’s simple-to-work-with graphical interface and, with no more than one single mouse click, you can see an in-depth system log, add or reboot an instance, clear the cached data for any site and much more. Shortly after you activate the Varnish platform for a certain domain or subdomain, it will start caching the webpages opened by your site visitors and once it has cached enough content, you’ll observe a substantially better website performance and a reduced load. With Varnish-dedicated system memory starting at 3 GB, you’ll be able to use the software platform for workload distribution purposes even if you run numerous sites on your dedicated server.
