Varnish is a web application accelerator platform, which caches data for faster access. It is sometimes called an HTTP reverse proxy too and it works between a web server and an Internet browser. When a website visitor loads a certain webpage, its content is requested by the web browser, and then the server processes this request and returns the necessary information. If Varnish is activated for a specific website, it will cache the pages at the very first request and if the visitor opens a cached page for a second time, the data will be delivered by the caching platform and not by the web server. The accelerated loading speed is a result of the considerably faster response time that Varnish offers as compared to any web server software. Of course, this doesn’t mean that the website visitors will continue being served the same content over and over again, as any update on any of the pages is reflected in the content that the Varnish platform stores in its memory.

Varnish in Website Hosting

Varnish comes as an optional upgrade with each website hosting and if you want to use it, you can add it to your hosting account through the Upgrades section in your Hepsia hosting Control Panel. There are two separate features that can be upgraded – the instances and the system memory. The first one refers to the number of the websites that you wish to use Varnish for, whereas the second, which is available in increments of 32 megabytes, refers to the total amount of content that the content caching platform can cache at any given time. Hepsia’s user-friendly interface will permit you to disable or to restart any instance, to view detailed logs or to delete the platform’s cache with just click of the mouse. For maximum results, you can employ a dedicated IP address for the Internet sites that will use the caching platform. With Varnish, your website will open substantially faster, which means more satisfied website visitors and prospective clients.

Varnish in Semi-dedicated Servers

The Linux semi-dedicated servers that we’re offering will allow you to employ Varnish once your new semi-dedicated server account has been set up, as the caching platform is offered by default. 64 megabytes of system memory will be assigned to Varnish the second your account is enabled, so you can take advantage of this workload balancing software as soon as your website has been published online. If you need more memory, you can get 32 MB at a time from the Upgrades section of the Hepsia Control Panel and it will be assigned to your semi-dedicated server in an instant. You can also increase the number of the Internet sites that employ Varnish, or the so-called ‘instances’, which are not directly bound to the amount of system memory that you use, which goes to say that you’ll enjoy more versatility. The platform will noticeably reduce the load on the semi-dedicated machine that your sites produce, so your website visitors can enjoy fast-loading web pages. You will be able to manage the Varnish caching platform without efforts from the Hepsia Control Panel using quick-access buttons. You’ll be able to start/disable any of the instances that you have, to delete the cached data for any of your sites or to see system log files.

Varnish in VPS Servers

You can use Varnish with any of our VPS server packages at no additional charge, as the data caching platform is pre-installed and is included by default. The only requirement is that the VPS server must come with the Hepsia hosting Control Panel, through which you will be able to set up Varnish for any of your websites with just a couple of clicks of the mouse. Each VPS package comes with a different amount of system memory for content caching purposes, but you’ll get at least several hundred MB, which is sufficient enough even for several traffic-heavy websites. Shortly after you set up the Varnish platform, it’ll begin caching the content that your site visitors browse, so you’ll notice the much faster site loading times and the lowered server load very soon. The Varnish platform will allow you to use a less pricey virtual server, as you will not need that much power to sustain the proper operation of your websites even if you run large-sized Internet sites with numerous visitors. Best results are accomplished if the Internet sites that use Varnish use also a dedicated IP address.

Varnish in Dedicated Servers

If you order a dedicated server with the Hepsia hosting Control Panel, you will get the Varnish content caching platform at no additional charge and you’ll exert complete control over it via a pretty easy-to-navigate interface – you will be able to start, to stop or to reboot an instance, to browse a detailed log, to clear the cache for any site and much more. The Varnish caching platform will have several gigabytes of virtual memory at its disposal, so even if you’ve got traffic-hungry websites with a vast number of visitors, you will notice the much better web page load times and the decreased server load. This will happen soon after you begin using Varnish, since it will need some time to cache the website content that visitors request. You can take full advantage of the platform’s potential if the websites that are using it also use a dedicated IP, but considering the fact that your dedicated server comes with a few IPs by default, you will not have to pay anything on top of the monthly fee for the server itself.
