Varnish is a web app accelerator platform, which caches information for faster response times. It is occasionally called an HTTP reverse proxy as well and it interacts between a web server and an Internet browser. When a site visitor loads a certain web page, its content is requested by the web browser, and then the web server handles this request and delivers the needed information. If Varnish is enabled for a particular website, it will cache its pages on the first request and if the visitor visits a cached page once more, the content will be delivered by the accelerator platform and not by the web server. The increased load speed is an end result of the much faster response time that the Varnish platform offers as compared with any web server software. At the same time, this does not mean that the website visitors will continue being served the same content again and again, because any update on any of the web pages is reflected in the content that the Varnish platform saves in its system memory.
Varnish in Shared Website Hosting
Varnish is offered as an optional upgrade with each Linux shared website hosting and if you want to use it, you can add it to your hosting account through the Upgrades section in your Hepsia Control Panel. There are two separate features that can be upgraded – the number of instances and the system memory. The first one depends on the number of the sites that you’d like to employ Varnish for and the second one, which is offered in increments of 32 megabytes, displays the maximum amount of content that the platform can cache at any particular time. Hepsia’s easy-to-use GUI will permit you to deactivate or to restart any instance, to see in-depth system logs or to delete the platform’s cache with just one click. For optimum results, you can use a dedicated IP for the Internet sites that will use the caching platform. With Varnish, your Internet site will load substantially faster, which means more satisfied website visitors and potential clients.
Varnish in Semi-dedicated Hosting
All our semi-dedicated hosting services come with Varnish by default, so you can make full use of the web accelerator tool and enhance the loading speed of any site that you host on our semi-dedicated servers. You’ll get 64 MB of system memory exclusively for the Varnish accelerator at no additional cost and you’ll be able to add an instance with no more than a couple of clicks of the mouse via the Hepsia hosting 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 megabytes through the Upgrades section of the Control Panel and it will be available to you right away. You can also add more instances as a separate upgrade, so you can decide whether plenty of data will be cached for a single website or if the available memory will be utilized by multiple websites. The Hepsia Control Panel will allow you to restart or to cancel any instance, to view the system log file associated with it or to clear the cached files using 1-click controls. To take full advantage of Varnish, you can assign a dedicated IP to the websites that will use it.
Varnish in VPS
You can use the workload balancing capabilities of Varnish with all our VPS services if you select Hepsia as your Control Panel. The Varnish content caching platform is available by default and the memory that it will be able to utilize to cache the content of your sites is dependent on the specific plan that you’ve picked, but even with the less powerful packages, you’ll have at least several hundred MB of system memory at your disposal solely for data caching purposes. This amount is sufficient to improve the performance of multiple Internet sites. It’ll take a little time for you to notice the results, since Varnish caches the content that website visitors request, but soon thereafter you’ll notice the considerably lowered load on the server and the increased site load speed. Varnish will permit you to make use of a lower-end plan for sites that would usually require a more high-priced web hosting solution.
Varnish in Dedicated Hosting
In case you order a dedicated server with the Hepsia Control Panel, you’ll acquire the Varnish content caching platform at no additional charge and you will have total control over it through a quite intuitive GUI – you’ll be able to start, to discontinue or to restart an instance, to view an elaborate system log, to clear the cached content associated with any site and much, much more. The Varnish caching platform will have several GB of virtual memory at its disposal, so even if you’ve got traffic-intensive sites with plenty of visitors, you will notice the tremendously faster website load times and the decreased load on your dedicated server. This will become a fact soon after you start using the Varnish platform, as it will require a certain amount of time to cache the web pages that users browse. You can make the most of the platform’s capacity in case the sites that are using it use also a dedicated IP, but considering the fact that your dedicated server comes with a few IP addresses by default, you will not need to pay anything on top of the monthly fee for the machine itself.
