Varnish is a web app accelerator platform, which caches information for the sake of faster response times. It is sometimes referred to as an HTTP reverse proxy too and it interacts between a web server and a browser. When a visitor loads a given web page, the content is requested by the browser, and then the server handles this browser request and delivers the requested data. If Varnish is enabled for a given site, it will cache the pages at the very first visit and if the visitor visits a cached page once again, the data will be delivered by the caching platform instead of the server. The boosted load speed is an end result of the substantially faster response time that Varnish offers compared to any server software. Of course, this doesn’t mean that the website visitors will continue seeing the same content over and over again, as any update on any of the web pages is reflected in the content that Varnish keeps in its system memory.

Varnish in Shared Website Hosting

Varnish comes as an optional upgrade with each shared website hosting and if you wish to use it, you can add it to your web hosting account using the Upgrades section in your Hepsia Control Panel. There are two separate things that can be upgraded – the number of instances and the memory. The first one refers to the number of the sites that you wish to employ Varnish for, whereas the second, which is available in increments of 32 MB, shows the maximum amount of content that the platform can cache at any given time. The Hepsia Control Panel’s simple-to-use graphical interface will allow you to remove or to reboot any instance, to check detailed logs or to clear the platform’s cache with just one click. For best results, you can use a dedicated IP for the websites that will use the caching platform. With Varnish, your Internet site will open tremendously faster, meaning more pleased site visitors and potential customers.

Varnish in Semi-dedicated Servers

The Varnish data caching platform is part of the default service set that you’ll receive in case you decide to host your sites in a semi-dedicated server account. You can activate it for any of your sites via our cutting-edge Hepsia Control Panel. The default amount of system memory that the Varnish platform can use to cache data is 64 MB, but in case you decide that you need more, you can upgrade this amount of memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, in other words – the number of the sites that can use this caching platform at the same time. As these two features are not tied to each other, you can use several websites with the default amount of memory or you can get more memory in increments of 32 megabytes and use all of it for one single site. The Varnish caching platform performs best when you set a dedicated IP address for the websites that utilize its power. Hepsia will offer you an easy means of rebooting any instance. Furthermore, you will be able to delete the cached contents with only one click of the mouse.

Varnish in VPS Servers

Varnish comes by default with each of the VPS web hosting service that we are offering given that the virtual server is ordered with the Hepsia Control Panel, so you can boost the overall performance of your websites with just a couple of mouse clicks. The more powerful the package, the more memory Varnish will have at its disposal, but even with a low-end package, the caching platform will be able to utilize several hundred MB, so even if you have several Internet sites, you will notice a considerable decrease in the overall server load and a much better page load speed. The Varnish platform will need to work for a while as the users browse the web pages and as soon as the content has been cached, you’ll perceive the effect. One of the benefits of using Varnish is that a lower-end and less pricey plan will do the exact same job as a more pricey one without the caching platform, so not only will your websites work better, but you will also save a certain amount of cash.

Varnish in Dedicated Servers

If you order a dedicated server with the Hepsia Control Panel, you’ll acquire the Varnish data caching platform at no additional fee and you will have complete control over it via a really time and effort saving GUI – you’ll be able to start, to cancel or to restart an instance, to browse an elaborate system log, to delete the cached content associated with any website and much more. The Varnish platform will have several GB of virtual memory at its disposal, so even if you have resource-requiring Internet sites with a large number of visitors, you’ll notice the considerably faster page load times and the reduced load on the dedicated machine. This will become a fact shortly after you start using the Varnish platform, as it will require some time to cache the website content that visitors access. You can take full advantage of the platform’s capability in case the Internet sites that are using it use also a dedicated IP, but since your server comes with a few IP addresses by default, you will not need to pay anything on top of your monthly charge for the server itself.
