Varnish is a website accelerator tool, which has been gaining a lot in popularity lately, because it can increase the load speed of any website, sometimes even by 100%, based on the content itself. This tool is sometimes referred to as a caching HTTP reverse proxy as well and is used to lower the overall load on the server and to improve the access speed for the website visitors. Whenever a visitor loads a page on a specific site, the web browser request is handled by the web server and the requested data is sent as a reply. If the Varnish accelerator is activated, it caches the pages that the site visitor browses and if any of them is loaded once again, it’s fetched by Varnish and not by the server directly. The performance improvement is due to the fact that the accelerator processes the browser requests substantially quicker than any web server, which leads to much faster browsing speeds for the site visitors. In case any content is changed meanwhile, the cached pages will also be updated the next time someone tries to access them.

Varnish in Shared Hosting

Varnish comes as an optional upgrade with each shared plan and if you wish to use it, you can add it to your website hosting account via the Upgrades section in your Hepsia Control Panel. There are two separate things that can be upgraded – the instances and the system memory. The first one depends on the number of the sites that you want to employ Varnish for and the second one, which is available in increments of 32 MB, indicates the maximum amount of content that the content caching platform can cache at any particular time. Hepsia’s easy-to-work-with graphical interface will permit you to turn off or to reboot any instance, to see detailed logs or to clear the platform’s cache with just a click. For maximum results, you can use a dedicated IP for the Internet sites that will use the platform. With Varnish, your site will open significantly faster, meaning more happy site visitors and potential customers.

Varnish in Semi-dedicated Servers

Varnish is included in the basic set of services that you’ll acquire in case you choose to host your sites in a semi-dedicated server account. You can activate it for any of your websites through our advanced Hepsia Control Panel. The default amount of memory that the Varnish caching platform can use to cache data is 64 megabytes, but in case you decide that you need more, you can upgrade this memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, i.e. the number of the sites that can use this platform simultaneously. Since these two things are not linked to each other, you can use a couple of 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 website. Varnish performs best if you set a dedicated IP address for the sites that utilize its power. Hepsia will provide you with an easy means of rebooting any instance. What’s more, you’ll be able to clear the cached files with only one mouse click.

Varnish in VPS Servers

You can use the load balancing capabilities of Varnish with all our VPS hosting plans in case you choose Hepsia as your hosting Control Panel. The Varnish content caching platform comes by default and the system memory that it’ll be able to utilize to cache the content of your websites is dependent upon the specific VPS plan that you have selected, but even with the less powerful plans, you’ll have no less than several hundred MB of memory at your disposal solely for content caching purposes. This amount is sufficient to optimize the overall performance of numerous Internet sites. It will take some time for you to see the effects, as the Varnish platform caches the content that website visitors request, but shortly thereafter you will notice the significantly reduced load on the VPS and the accelerated site load speed. The Varnish caching platform will allow you to use a lower-end VPS plan for sites which would usually require a more high-priced hosting solution.

Varnish in Dedicated Servers

All dedicated web hosting plans that are ordered with the custom-developed Hepsia web hosting Control Panel feature Varnish, which is among the pre-installed platforms that you’ll get with the dedicated server. The Varnish content caching platform can be activated and administered effortlessly through Hepsia’s simple-to-use graphical interface and, with no more than one single click of the mouse, you can browse a comprehensive log, add or reboot an instance, clear the cached files associated with any website and much more. Soon after you activate Varnish for a certain domain or subdomain, it will start caching the webpages accessed by the website visitors and as soon as it has cached enough web content, you will perceive a significantly better website performance plus a lowered load on your server. With Varnish-dedicated memory starting at 3 gigabytes, you’ll be able to use the software platform for workload balancing purposes even if you host lots of Internet sites on the server.
