Varnish is a web accelerator platform, which caches data for quicker access. It is occasionally called an HTTP reverse proxy as well and it interacts between a web server and its users. When a site visitor accesses a particular web page, the content is requested by the web browser, and then the server processes this request and delivers the requested info. If Varnish is activated for a site, it will cache the pages at the very first request and in case the visitor opens a cached page once more, the content will be delivered by the caching platform instead of the web server. The boosted load speed is an end result of the much faster response time that the Varnish platform offers compared with any web server software. Of course, this doesn’t mean that the site visitors will continue seeing the exact same content over and over again, as any modification on any of the pages is reflected in the content that the Varnish platform saves in its memory.

Varnish in Hosting

In case you host your Internet sites in a hosting account with us, you’ll be able to activate Varnish with a couple of mouse clicks via your Control Panel. The caching platform is available as an optional upgrade with all our shared plans and you can choose the number of the websites that will use it and the total amount of system memory that will be used for the cached data. The two upgradeable features in the Upgrades section of the Control Panel are the amount of memory and the number of instances and they’re not directly linked to each other, so you can decide if you need plenty of memory for one single large-size site or less memory for multiple smaller ones. You can unleash the full potential of the Varnish platform in case the sites use a dedicated IP address. With the hosting Control Panel, you can effortlessly start/reboot/stop an instance, clear the cached data individually for each website which employs Varnish or see an elaborate log file.

Varnish in Semi-dedicated Servers

All our Linux semi-dedicated service include Varnish by default, so you can use the web application accelerator tool and speed up any site that you host on our semi-dedicated servers. You’ll get 64 megabytes of memory dedicated to Varnish at no additional cost and you will be able to activate an instance with no more than a few mouse clicks via the Hepsia Control Panel, which is included with the semi-dedicated server plans. In case you want more memory, the latter is available in increments of 32 MB in the Upgrades section of the Control Panel and it will be at your disposal instantly. You can also order more instances as a separate upgrade, so you can choose if lots of content will be cached for one site or whether the available memory will be used by several Internet sites. The Hepsia Control Panel will allow you to restart or to discontinue any instance, to see the system log associated with it or to clear the cached files using single-click buttons. To take full advantage of the Varnish accelerator, you can assign a dedicated IP to the sites that will use it.

Varnish in VPS Servers

You can take full advantage of the load balancing potential of Varnish with all our Linux VPS servers if you choose Hepsia as your web hosting Control Panel. The caching platform is offered by default and the amount of system memory that it’ll be able to use to cache the content of your websites is dependent upon the given VPS plan that you’ve chosen, but even with the lower-end packages, you’ll have at least several hundred MB of system memory at your disposal solely for data caching purposes. This amount is sufficient enough to improve the performance of multiple Internet sites. It will take a little time for you to see the effects, as the Varnish platform caches the content that visitors open, but shortly after that you’ll notice the considerably less load on the machine and the increased site loading speed. The Varnish caching platform will allow you to make use of a less powerful Virtual Private Server plan for Internet sites that would typically require a more costly web hosting service.

Varnish in Dedicated Servers

All dedicated service that are ordered with the custom-developed Hepsia hosting Control Panel come with Varnish, which is among the pre-installed platforms that you’ll get with the machine. The Varnish content caching platform can be set up and administered with no effort through the Hepsia Control Panel’s simple-to-work-with graphical interface and, with no more than one single click, you can browse a detailed log, add or restart an instance, clear the cache for any website and much more. Shortly after you activate Varnish for a certain domain or sub-domain, it will begin caching the pages opened by your website visitors and once it has cached enough web content, you will perceive a tremendously faster website performance plus a reduced load. With Varnish-dedicated memory starting at three gigabytes, you will be able to use the software platform for workload distribution purposes even if you run plenty of sites on the dedicated machine.
