Varnish is a web accelerator platform, which caches data for the sake of quicker access. It is sometimes called an HTTP reverse proxy too and it works between a web server and its users. When a site visitor accesses a certain web page, the content is requested by the web browser, and then the server handles this request and delivers the needed content. If Varnish is activated for a particular website, it will cache the pages on the very first visit and if the visitor opens a cached page again, the content will be delivered by the accelerator platform instead of the server. The boosted loading speed is an end result of the substantially faster response speed that Varnish offers as compared to any web server software. At the same time, this doesn’t mean that the website visitors will continue seeing the very same content over and over again, because any update on any of the web pages is reflected in the content that Varnish stores in its memory.

Varnish in Shared Website Hosting

Varnish is available as an optional upgrade with each of our Linux shared website hosting plans. You can add it to your web hosting account from the Hepsia hosting Control Panel, which comes with all shared packages and you’ll get a very simple-to-use GUI, which will grant you full control over the content caching system. Using 1-click fast-access buttons, you can restart or cancel any of the instances, in other words – Varnish will no longer be activated for a certain site. You can also check an elaborate system log or delete the cache associated with any of the websites. When you add Varnish to your web hosting plan, you will be able to choose the total amount of memory that will be available to you for content caching purposes and how many websites will use Varnish. You can always order more memory in increments of 32 megabytes and, for optimal performance, you can allocate a dedicated IP to the sites that will use Varnish. This will permit you to take full advantage of your websites and to have numerous pleased site users.

Varnish in Semi-dedicated Servers

All our Linux semi-dedicated plans include Varnish by default, so you can use the web app accelerator tool and increase the load speed of any website that you host on our platform.

If you need more memory, the latter is available in increments of 32 MB through the Upgrades section of the Control Panel and it will be available to you right away. You can also order more instances as an upgrade, so you can choose whether lots of data will be cached for a single website or if the memory will be used by multiple Internet sites. Hepsia will permit you to reboot or to terminate any instance, to view the system log for it or to delete the cached data using one-click buttons. To get the most out of Varnish, you can allocate a dedicated IP to the Internet sites that will employ it.

Varnish in VPS Servers

Varnish is included by default with each of the VPS plans offered by our company on the condition that the Virtual Private Server is ordered with the Hepsia Control Panel, so you can enhance the work of your websites with just a few clicks. The more powerful the plan, the more system memory will be available to Varnish, but even with a low-end plan, the caching platform will be able to utilize several hundred MB, so even if you run several sites, you’ll notice a noticeable reduction in the overall server load and a much better webpage loading speed. The Varnish platform will need to work for a little while while the users navigate the site and once the website content has been cached, you will distinguish the results. One of the upsides of employing Varnish is that a lower-end and less high-priced VPS package will do the exact same job as a more pricey one without the platform, so not only will your sites work significantly better, but you will also spare some money.

In case you order a dedicated server with the Hepsia hosting Control Panel, you’ll acquire the Varnish platform at no additional cost and you’ll exert complete control over it via a quite user-friendly GUI – you’ll be able to start, to deactivate or to restart an instance, to browse an in-depth system log, to delete the cached files for any Internet site and much, much more. The Varnish platform will have several gigabytes of memory at its disposal, so even if you’ve got large-size Internet sites with a lot of visitors, you’ll notice the substantially better website loading times and the less load. This will happen shortly after you start using the Varnish platform, since it will require a certain amount of time to cache the website content that visitors access. You can take full advantage of the platform’s potential in case the Internet sites that are using it use also a dedicated IP address, but considering the fact that your server includes a couple of IPs by default, you won’t need to pay anything on top of the monthly fee for the server itself.
