Varnish is a website accelerator, which has been gaining a lot of popularity lately, as it can increase the load speed of any website, sometimes even by 100%, depending on the content. This tool is occasionally referred to as an HTTP reverse proxy as well and is used to reduce the overall load on the physical machine and to increase the access speed for the website visitors. Every time a visitor opens a page on a specific site, the web browser request is taken care of by the web server and the requested information is served as a reply. If Varnish is enabled, it caches the pages that the visitor opens and if any of them is opened once more, it is fetched by Varnish and not by the server directly. The boost in the performance is due to the fact that the accelerator handles the browser requests substantially faster than any web server, which results in much faster browsing speeds for the visitors. If any data is updated meanwhile, the cached pages will also be ‘refreshed’ the next time someone accesses them.

Varnish in Cloud Hosting

Varnish is available as an optional upgrade with all our Linux cloud services. You can add it to your website hosting account via the Hepsia Control Panel, which comes with all shared plans and you’ll get an amazingly simple-to-use GUI, which will give you full control over the content caching platform. Using 1-click quick-access buttons, you can reboot or discontinue any of the instances, in other words – Varnish will no longer be activated for a given website. You can also see a detailed system log or delete the cache for any of the websites. When you add Varnish to your hosting package, you will be able to choose the maximum amount of memory that will be available to you for data caching purposes and how many websites will use Varnish. You can always get more memory in increments of 32 MB and, for best performance, you can allocate a dedicated IP to the sites that will use Varnish. This will allow you to get the most out of your sites and to have many pleased website users.

Varnish in Semi-dedicated Hosting

The Varnish content caching platform is an essential part of the basic set of services that you’ll acquire when you choose to host your websites under a semi-dedicated server account. You can enable it for any of your websites through our next-gen Hepsia Control Panel. The default amount of system memory that Varnish can use to cache content is 64 megabytes, but in case you decide that you want more, you can upgrade this 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 at the same time. Since these two features are not linked to each other, you can use a couple of instances 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. Varnish works best when you use a dedicated IP address for the websites that utilize its power. The Hepsia Control Panel will provide you with a simple means of rebooting any instance. In addition, you’ll be able to clear the cached files with only one click of the mouse.

Varnish in VPS

You can take advantage of Varnish with each of our virtual private server packages at no extra cost, since the caching platform is pre-installed and is included by default. The one and only requirement is that the virtual server must be ordered with the Hepsia Control Panel, via which you will be able to activate Varnish for any of your Internet sites with just a couple of mouse clicks. Each VPS plan features a different amount of memory for content caching purposes, but you will have minimum several hundred megabytes, which is quite enough even for several large Internet sites. Soon after you activate the Varnish platform, it will begin caching the content that your site visitors request, so you will notice the much faster webpage load times and the less load on the VPS server very soon. The platform will allow you to use a less costly VPS, as you will not need that many resources to guarantee the proper operation of your websites even if you have heavy-traffic sites with a lot of visitors. Best results are accomplished if the sites that use the Varnish caching platform also use a dedicated IP.

Varnish in Dedicated Hosting

All Linux dedicated hosting that are ordered with the custom-built Hepsia website hosting Control Panel come with Varnish, which is one of the pre-installed platforms that you’ll get with the dedicated machine. The Varnish content caching platform can be enabled and managed with no effort from the Hepsia Control Panel’s simple-to-work-with GUI and, with no more than one click of the mouse, you can browse an elaborate log, add or reboot an instance, delete the cached files associated with any Internet site and much, much more. Soon after you enable Varnish for a given domain or subdomain, it will begin caching the web pages loaded by the site visitors and once it has cached enough content, you will perceive a considerably faster site performance as well as a lowered server load. With Varnish-dedicated virtual memory starting at three gigabytes, you will be able to use the platform for workload balancing purposes even if you run numerous Internet sites on your server.
