Varnish is a website accelerator, which has been gaining a lot of popularity in recent years, because it can increase the loading speed of any website, at times even by 100 percent, based on the content. This tool is sometimes called a caching HTTP reverse proxy too and is used to decrease the overall load on the physical server and to improve the access speed for the website visitors. Each time a visitor loads a page on a given site, the web browser request is taken care of by the web server and the requested content is served as a response. If the Varnish accelerator is activated, it caches the pages that the website visitor opens and if any of them is loaded again, it is served by Varnish and not by the server directly. The performance boost is due to the fact that the accelerator processes the web requests significantly faster than any web server, which leads to much faster browsing speeds for the users. In case any content is changed meanwhile, the cached webpages will also be ‘refreshed’ the next time somebody tries to access them.

Varnish in Web Hosting

Varnish comes as an optional upgrade with each of our web hosting plans. You can add it to your hosting account through the Hepsia hosting Control Panel, which is available with all shared packages and you will get a pretty intuitive interface, which will grant you full control over the data caching platform. Using one-click fast-access controls, you can reboot or stop any of the instances, in other words – Varnish will no longer be activated for a specific site. You can also view a detailed log or delete the cache associated with any of the sites. When you add Varnish to your shared web hosting package, you’ll be able to choose the total amount of memory that will be at your disposal for caching purposes and how many websites will use Varnish. You can always order more memory in increments of 32 MB and, for top performance, you can get a dedicated IP for the sites that will use Varnish. This will permit you to take full advantage of your websites and to have numerous pleased visitors.

Varnish in Semi-dedicated Servers

The Varnish caching platform is an essential part of the default service set that you will receive if you choose to host your websites under a semi-dedicated server account. You can activate it for any of your websites via our innovative Hepsia hosting Control Panel. The default memory that the Varnish platform can use to cache content is 64 MB, but in case 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 simultaneously. As these two features aren’t linked to each other, you can use a few instances with the default memory or you can add more memory in increments of 32 MB and use all of it for a single web site. Varnish works best when you use a dedicated IP for the websites that utilize its power. Hepsia will give you a simple means of rebooting any instance. On top of that, you’ll be able to clear the cached content with only one single click.

Varnish in VPS Servers

Varnish is included by default with each of the VPS plans that we offer as long as the machine is ordered with the Hepsia Control Panel, so you can enhance the overall performance of your sites with just a couple of clicks of the mouse. The more powerful the plan, the more memory Varnish will have at its disposal, but even with a less powerful package, the platform will be able to utilize several hundred megabytes, so even if you own a number of sites, you’ll notice a considerable decrease in the overall server load and a substantially better web page loading speed. The Varnish platform will have to work for a while while the visitors navigate the site and as soon as the content has been cached, you will observe the effect. One of the benefits of using Varnish is that a less powerful and less costly VPS package will do the exact same job as a more expensive one without the caching platform, so not only will your sites work substantially better, but you will also save a certain amount of money.

Varnish in Dedicated Servers

All dedicated web hosting plans which are ordered with the tailor-made Hepsia hosting Control Panel come with Varnish, which is among the pre-installed platforms that you’ll get with the dedicated server. The Varnish data caching platform can be enabled and managed with ease through Hepsia’s time and effort saving interface and, with no more than a click, you can see an exhaustive log, create or reboot an instance, delete the cached content associated with any site and much more. Soon after you set up Varnish for a specific domain or subdomain, it will begin caching the webpages requested by the website visitors and once it has cached enough web content, you will observe a considerably faster site performance as well as a decreased load on the machine. With Varnish-dedicated memory starting at 3 GB, you will be able to use the platform for load distribution purposes even if you host a large number of websites on your server.
