Varnish is a web application accelerator platform, which caches content for the sake of quicker access. It is sometimes referred to as an HTTP reverse proxy too and it works between a web server and a web browser. When a visitor opens a particular webpage, its content is requested by the web browser, and then the web server processes this browser request and sends back the required data. If Varnish is enabled for a specific site, it will cache the pages on the first request and if the visitor opens a cached page for a second time, the content will be delivered by the caching platform instead of the web server. The improved speed is a result of the significantly faster response time that Varnish offers compared with any web server software. At the same time, this doesn’t mean that the 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 keeps in its system memory.

Varnish in Cloud Hosting

Varnish is available as an optional upgrade with each of our cloud hosting. You can add it to your web hosting account through the Hepsia Control Panel, which comes with all shared hosting plans and you’ll get a very easy-to-use interface, which will grant you complete control over the content caching system. Using one-click quick-access buttons, you can restart or discontinue any of the instances, in other words – Varnish will no longer be enabled for a specific Internet site. You can also see an in-depth log or erase the cache associated with any of the websites. When you add Varnish to your web hosting plan, you’ll be able to select the maximum amount of memory that will be available to you for data caching purposes and how many sites will use Varnish. You can always get more memory in increments of 32 megabytes and, for optimal performance, you can assign a dedicated IP address to the sites that will use Varnish. This will allow you to take full advantage of your sites and to have many satisfied website users.

Varnish in Semi-dedicated Hosting

Varnish is a feature, which comes by default with all Linux semi-dedicated services that we’re offering and you can use it for load distribution purposes. It is available in your Hepsia hosting Control Panel. The Varnish content caching platform comes with 64 MB of system memory for cached content storing purposes and you can employ it with any website that you host in the semi-dedicated server account. In case you need more than that, you can increase the system memory allocation. The memory itself is available in increments of 32 MB through the Upgrades section of the Control Panel. The exact same Upgrades section will enable you to activate more instances as well, in case you’d like to use the Varnish platform with multiple websites. The two things can be ordered separately – you can cache the content of one single resource-hungry website or run several Internet sites with the default memory. You can take full advantage of the Varnish caching platform in case you’ve got a dedicated IP and you can get one with your semi-dedicated package as well. The Hepsia Control Panel will give you full control over the platform and, with no more than one click, you will be able to delete the cached data, to check a log file or to restart an instance.

Varnish in VPS

We provide Varnish with all Hepsia-managed Linux VPS, so if you purchase a VPS with this hosting Control Panel, you will be able to make full use of the caching platform at no extra cost. Varnish can use different amounts of system memory for caching purposes based on the very plan that you have selected during the server order process, but at any rate, this amount will not be less than several hundred megabytes. This is more than enough to improve the overall performance of a number of frequently visited sites, so the better site browsing speeds and the decreased load on your server will be perceptible. The result may not be observable instantly, as Varnish will require a certain amount of time to cache the website content that people open, but soon after you activate it, you’ll observe its full capacity. This caching platform will allow you to use a less powerful VPS and to pay less cash to get the same performance you would get with a higher-end machine without Varnish.

Varnish in Dedicated Hosting

All dedicated hosting services which are ordered with the custom-developed Hepsia web hosting Control Panel come with Varnish, which is among the pre-installed software platforms that you will get with the server. The Varnish platform can be set up and administered without effort through Hepsia’s simple-to-work-with GUI and, with no more than one single mouse click, you can see an in-depth system log, add or restart an instance, clear the cached data for any Internet site and much, much more. Soon after you configure Varnish for a certain domain or sub-domain, it will start caching the web pages opened by the site visitors and as soon as it has cached enough web content, you will observe a considerably better website performance and a reduced load on your dedicated server. 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 an immense number of Internet sites on your server.
