Varnish is a web application accelerator platform, which caches data for the sake of faster response times. It’s sometimes called an HTTP reverse proxy too and it works between a web server and a web browser. When a visitor opens a given page, its content is requested by the Internet browser, and then the server processes this request and delivers the needed content. If Varnish is enabled for a particular website, it will cache the pages at the very first visit and in case the user accesses a cached page for a second time, the data will be delivered by the caching platform instead of the server. The increased load speed is an end result of the significantly faster response time that Varnish offers as compared to any server software. Of course, this doesn’t mean that the site visitors will keep seeing the very same content over and over again, since any change on any of the pages is reflected in the content that Varnish keeps in its system memory.

Varnish in Cloud Hosting

In case you host your websites in a cloud hosting account with us, you will be able to activate Varnish with a few mouse clicks from your Control Panel. The data caching platform is available as an optional upgrade with all our packages and you can select the number of the sites that will use it and the maximum storage space that will be used for the cached data. The two upgradeable features in the Upgrades section of the Control Panel are the number of instances and the amount of memory and they’re not directly linked to each other, so you can decide whether you need plenty of memory for a single large-size website or less memory for multiple smaller ones. You can take advantage of the full potential of the Varnish platform if the websites use a dedicated IP address. Using the hosting Control Panel, you can swiftly start/reboot/disable an instance, clear the cached files individually for each site that employs the Varnish platform or see an elaborate log.

Varnish in Semi-dedicated Hosting

The Varnish platform is an essential part of the standard service set that you’ll get if you choose to host your sites in a semi-dedicated server account. You can configure it for any of your Internet sites via our innovative Hepsia hosting Control Panel. The default amount of system memory that the Varnish caching platform can use to cache data is 64 MB, but if you decide that you need more, you can upgrade this memory from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, i.e. the number of the websites that can use this platform at the same time. Since these two things aren’t tied to each other, you can use several sites with the default amount of memory or you can add more memory in increments of 32 megabytes and use all of it for a single site. The Varnish caching platform works best when you set a dedicated IP address for the Internet sites that utilize its power. The Hepsia Control Panel will give you an easy means of restarting any instance. In addition, you will be able to clear the cached files with just one single click of the mouse.

Varnish in Dedicated Hosting

If 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 through a pretty easy-to-work-with GUI – you’ll be able to start, to delete or to reboot an instance, to view an elaborate system log, to clear the cached content associated with any site and much, much more. The Varnish platform will have several gigabytes of virtual memory at its disposal, so even if you manage traffic-intensive sites with an enormous number of visitors, you will notice the much faster page loading speeds and the decreased load on your dedicated machine. This will become a fact shortly after you begin using the Varnish platform, as it will need some time to cache the pages that users access. You can get the most out of the platform’s capability if the sites that are using it use also a dedicated IP address, but since your server includes several IPs by default, you will not have to pay anything on top of the monthly charge for the server itself.
