Varnish is a website accelerator platform, which caches information for faster access. It is sometimes referred to as an HTTP reverse proxy too and it interacts between a web server and a web browser. When a visitor loads a specific page, the content is requested by the browser, and then the server handles this browser request and delivers the requested content. If Varnish is enabled for a website, it will cache the pages at the first request and if the user accesses a cached page once more, the info will be delivered by the accelerator platform instead of the server. The increased load speed is a result of the much faster response time that the Varnish platform offers compared with any web server software. Of course, this doesn’t mean that the site visitors will keep seeing the same content again and again, because any modification on any of the web pages is reflected in the content that Varnish saves in its system memory.

Varnish in Cloud Hosting

Varnish is available as an optional upgrade with all our Linux cloud hosting. You can add it to your web hosting account through the Hepsia Control Panel, which is offered with all shared hosting plans and you’ll get a pretty intuitive GUI, which will grant you complete control over the content caching system. Using one-click fast-access controls, you can restart or cancel any of the instances, i.e. Varnish will no longer be activated for a given site. You can also see a comprehensive system log or delete the cache associated with any of the websites. When you add Varnish to your shared hosting plan, you’ll be able to select the maximum amount of memory that will be available to you for data caching purposes and the number of the websites that will use Varnish. You can always add more memory in increments of 32 MB and, for optimum performance, you can allocate a dedicated IP address to the sites that will use Varnish. This will enable you to take full advantage of your Internet sites and to have many pleased website users.

Varnish in Semi-dedicated Servers

The semi-dedicated servers that we offer will allow you to employ Varnish as soon as your brand new semi-dedicated account has been activated, as the platform comes by default. 64 MB of system memory will be assigned to Varnish the moment your account is activated, so you can use this load balancing software as soon as your website has been taken online. If you need more memory, you can add 32 megabytes at a time from the Hepsia hosting Control Panel’s Upgrades section and it will be allocated to your semi-dedicated machine in an instant. You can also increase the number of the Internet sites that employ Varnish, or the so-called ‘instances’, which are not bound directly to the amount of system memory that you use, which means that you will enjoy more flexibility. The Varnish platform will substantially reduce the load on the semi-dedicated machine that your websites generate, so your visitors can enjoy fast-opening web pages. You’ll be able to manage the Varnish platform without efforts via the Control Panel using quick-access buttons. You will be able to start/remove any of the instances that you’ve got, to clear the cached files associated with any of your sites or to see system logs.

Varnish in VPS Servers

You can use Varnish with any of our VPS server packages at no additional charge, as the caching platform is pre-installed and is available by default. The one and only precondition is that the virtual server must be ordered with the Hepsia hosting Control Panel, via which you will be able to activate Varnish for any of your sites with only a few clicks of the mouse. Each plan includes a different amount of system memory for content caching purposes, but you’ll have no less than several hundred MB, which is sufficient even for multiple traffic-intensive websites. Soon after you activate Varnish, it’ll begin caching the content that your site visitors request, so you’ll notice the tremendously faster page loading times and the lowered load on the VPS server very soon. The Varnish caching platform will permit you to use a less costly VPS, as you will not need that many resources to guarantee the proper operation of your sites even if you own busy websites with lots of visitors. Best results are accomplished if the Internet sites that use the Varnish caching platform also use a dedicated IP.

Varnish in Dedicated Servers

If you need a powerful hosting solution and you get any of the Linux dedicated web hosting plans that we are offering, you’ll be able to use the Varnish caching platform to improve the performance of your Internet sites at no extra cost on the condition that the dedicated machine is ordered with our next-gen Hepsia hosting Control Panel. Its easy-to-use GUI will enable you to monitor system processes, to delete the cache or to reboot any instance with one single click of the mouse. The smallest amount of memory that the Varnish caching platform can use to cache Internet site content is 3 gigabytes, which is more than enough for a vast collection of heavy sites, so your dedicated server will be able to cope with an enormous system load while your Internet site visitors are having a seamless web browsing experience. Since your server will include a number of dedicated IP addresses, you will be able to use Varnish’s full capacity.
