Varnish is a web app accelerator, which has been gaining a lot in popularity lately, as it can increase the load speed of any website, sometimes even by 100%, depending on the content itself. This tool is occasionally called an HTTP reverse proxy too and is used to decrease the overall load on the physical server and to boost the access speed for the site visitors. Every time a visitor accesses a page on a specific website, the web browser request is taken care of by the web server and the requested data is sent as a response. If Varnish is activated, it caches the web pages that the website visitor browses and in case any of them is opened again, it’s fetched by Varnish and not by the server directly. The improvement in the overall performance comes from the fact that the accelerator processes the web requests substantially quicker than any web server, which leads to much faster browsing speeds for the users. In case any content is modified in the meantime, the cached webpages will also be updated the next time someone opens them.

Varnish in Semi-dedicated Servers

All our semi-dedicated servers include Varnish by default, so you can take advantage of the web accelerator tool and optimize the loading speed of any site that you host on our platform. You’ll get 64 MB of system memory dedicated to the Varnish accelerator at no extra charge and you’ll be able to enable an instance with no more than a couple of clicks of the mouse from the Hepsia Control Panel, which comes with the semi-dedicated server plans. If you need more memory, the latter is offered in increments of 32 megabytes through the Control Panel’s Upgrades section and it will be available to you straight away. You can also add more instances as a separate upgrade, so you can decide if a lot of data will be cached for one site or whether the available memory will be utilized by different sites. Hepsia will enable you to restart or to remove any instance, to see the system log associated with it or to delete the cached content using one-click controls. To take full advantage of the Varnish accelerator, you can set a dedicated IP for the websites that will use it.

Varnish in VPS Servers

We offer Varnish with all of the Hepsia-equipped VPS servers, so in case you acquire a server with this hosting Control Panel, you’ll be able to make use of the data caching platform at no additional charge. The Varnish platform can use different amounts of system memory for caching purposes based on the very Virtual Private Server package that you’ve chosen during the VPS order process, but nevertheless, this amount will not be less than several hundred megabytes. This is more than enough to improve the work of several traffic-heavy sites, so the better site browsing speeds and the decreased load on the server will be perceivable. The effect may not be visible immediately, since the Varnish platform will need a certain amount of time to cache the content that visitors browse, but soon after you set it up, you’ll perceive its full capacity. This caching platform will allow you to use a less powerful server and to give less money to get the same performance you’d get with a higher-end virtual machine without Varnish.

Varnish in Dedicated Servers

In case you order a dedicated server with the Hepsia hosting Control Panel, you will obtain the Varnish platform at no extra fee and you will exert total control over it through an incredibly easy-to-navigate GUI – you will be able to start, to terminate or to reboot an instance, to view a comprehensive log, to delete the cached data for any website and much more. The Varnish platform will have several GB of virtual memory at its disposal, so even if you have resource-absorbing sites with a lot of visitors, you will notice the substantially faster site load times and the reduced load on the dedicated machine. This will become a fact shortly after you begin using the Varnish platform, as it will need some time to cache the web pages that visitors open. You can make the most of the platform’s capabilities in case the sites that are using it use also a dedicated IP, but since your dedicated server comes with several IP addresses by default, you will not have to pay anything on top of your monthly charge for the machine itself.
