Varnish is a web accelerator platform, which caches content for faster response times. It’s occasionally referred to as an HTTP reverse proxy too and it works between a web server and an Internet browser. When a site visitor loads a certain page, its content is requested by the web browser, and then the server handles this browser request and delivers the requested info. If Varnish is enabled for a specific website, it will cache its pages on the very first request and in case the visitor opens a cached page again, the content will be delivered by the accelerator platform and not by the server. The improved speed is a result of the significantly faster response time that Varnish offers compared with any web server software. Of course, this doesn’t mean that the website visitors will continue seeing the very same content over and over again, because any modification on any of the web pages is reflected in the content that Varnish keeps in its memory.

Varnish in Cloud Website Hosting

You can unleash Varnish’s full potential and improve the loading speed of your sites regardless of the cloud website hosting plan that you have chosen and you can activate and configure the content caching platform with a couple of clicks of the mouse through the simple-to-use GUI offered by our next-generation Hepsia Control Panel. In the meantime, you’ll be able to choose two separate things – how many websites will employ the Varnish caching platform, i.e. the number of instances, and how much content will be cached, in other words – the amount of memory. The latter is available in increments of 32 megabytes and is not tied to the number of instances, so you can order more instances and less memory and the other way around. If you have lots of content on a specific website and you attract many website visitors, more system memory will guarantee you better results. You may also consider using a dedicated IP for the Internet sites that will use the Varnish platform. Hepsia will offer you easy one-click buttons for terminating or restarting any instance, for deleting the cache for each site and for viewing exhaustive logs.

Varnish in Semi-dedicated Servers

The semi-dedicated servers that we offer will permit you to use Varnish once your brand-new semi-dedicated server account has been opened, since the content caching platform is offered by default. 64 megabytes of system memory will be allocated to Varnish the second your account is activated, so you can take advantage of this load distribution software as soon as your site has been launched. If you are in need of more system memory, you can add 32 megabytes at a time from the Upgrades section of the Hepsia Control Panel and it will be allocated to your semi-dedicated server right away. You can also increase the number of the websites that employ Varnish, or the so-called ‘instances’, which are not directly bound to the amount of memory that you use, which suggests that you’ll enjoy more freedom. The caching platform will noticeably reduce the load on the server caused by your websites, so your visitors can enjoy fast-loading pages. You will be able to manage Varnish with no effort from your Control Panel using quick-access controls. You’ll be able to start/shut down any of the instances that you’ve got, to delete the cached content for any of your sites or to view system logs.

Varnish in VPS Servers

You can take advantage of Varnish with all our VPS server plans at no additional charge, as the content caching platform is pre-installed and is included by default. The one and only precondition is that the Virtual Private Server must come with the Hepsia hosting Control Panel, through which you will be able to activate Varnish for any of your sites with just a couple of mouse clicks. Each VPS package features a different amount of memory for content caching purposes, but you’ll get at least several hundred megabytes, which is enough even for multiple large-sized sites. Soon after you enable Varnish, it’ll start caching the content that your site visitors access, so you will notice the tremendously better site loading times and the reduced load on your virtual machine in no time. Varnish will allow you to use a less expensive Virtual Private Server, as you won’t need that many resources to guarantee the correct operation of your Internet sites even if you’ve got large-size sites with a lot of visitors. Best results are achieved if the Internet sites which use Varnish also use a dedicated IP.

Varnish in Dedicated Servers

In case you order a dedicated server with the Hepsia Control Panel, you’ll acquire the Varnish platform at no additional fee and you’ll have full control over it through an extremely time and effort saving graphical interface – you’ll be able to start, to disable or to restart an instance, to see an in-depth system log, to clear the cached data for any site and much, much more. Varnish will have several GB of memory at its disposal, so even if you manage resource-absorbing Internet sites with an immense number of visitors, you’ll notice the much better page loading speeds and the decreased load on the dedicated machine. This will happen soon after you begin using Varnish, since it will require a certain amount of time to cache the web pages that users request. You can make the most of the platform’s capacity 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 won’t need to pay anything on top of the monthly fee for the machine itself.
