Varnish is a website accelerator platform, which caches data for quicker response times. It is occasionally referred to as an HTTP reverse proxy too and it works between a web server and an Internet browser. When a site visitor accesses a particular webpage, the content is requested by the browser, and then the web server processes this browser request and returns the required data. If Varnish is activated for a certain site, it will cache its pages at the very first visit and in case the user visits a cached page again, 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 substantially faster response speed that the Varnish platform offers as compared to any server software. At the same time, this doesn’t mean that the website visitors will continue being served the very same content again and again, because any change on any of the web pages is reflected in the content that Varnish caches in its system memory.

Varnish in Shared Hosting

In case you host your Internet sites under a shared hosting account with us, you will be able to activate Varnish with several clicks through your Control Panel. The caching platform is available as an optional upgrade with all our shared hosting plans and you can select the number of the websites that will use it and the total storage space that will be used for the cached content. The two features that can be upgraded in the Upgrades section of the Control Panel are the amount of memory and the number of instances and they aren’t tied directly to each other, so you can decide whether you want lots of memory for one large-scale website or less memory for several smaller ones. You can make use of the full potential of the Varnish caching platform if the sites use a dedicated IP. Using the hosting Control Panel, you can quickly start/reboot/disable an instance, delete the cached data independently for each website that uses the Varnish platform or check a detailed log file.

Varnish in Semi-dedicated Servers

The Varnish platform is an essential part of the standard set of services that you will obtain when you choose to host your sites under a semi-dedicated server account. You can activate it for any of your Internet sites via our advanced Hepsia hosting Control Panel. The default memory that the Varnish caching platform can use to cache data is 64 MB, but in case you decide that you need more, you can upgrade this memory from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, in other words – the number of the sites that can use this platform simultaneously. Since these two things aren’t linked to each other, you can use a couple of instances with the default memory or you can add more memory in increments of 32 megabytes and use all of it for one single website. The Varnish platform works best when you get a dedicated IP address for the sites that utilize its power. The Hepsia Control Panel will provide you with a simple means of restarting any instance. In addition, you’ll be able to delete the cached files with just one click.

Varnish in VPS Servers

The Varnish platform is included by default with all VPS plans that we’re offering given that the server is ordered with the Hepsia hosting Control Panel, so you can enhance the overall performance of your websites with just a couple of clicks. The more powerful the package, the more memory will be available to Varnish, but even with a lower-end plan, the platform will be able to utilize several hundred megabytes, so even if you run a handful of sites, you’ll notice a considerable reduction in the overall server load and a substantially better site loading speed. The Varnish platform will have to work for a while as the users browse the web pages and once the website content has been cached, you’ll observe the results. One of the upsides of employing Varnish is that a less powerful and less expensive VPS package will accomplish the exact same job as a more expensive one without the platform, so not only will your sites work much better, but you will also save some cash.

Varnish in Dedicated Servers

You can employ Varnish to boost the load speed of any website that is hosted on a dedicated server from us if the Hepsia hosting Control Panel is pre-installed on the machine. Not only will you get the caching platform ready to be used at no additional charge, but you’ll also exert full control over it through Hepsia’s easy-to-work-with GUI. It’ll take only one single click to start or terminate an instance or to clear the cached content for any site that’s using Varnish and in case you are more trained, you can also check the platform’s logs. Varnish comes with no less than three gigabytes of system memory for caching purposes, so even in case you run a lot of websites on your machine and they all use the platform, the improvement in their performance will be detectable. You will simply need to wait for a while till Varnish caches whatever content the site visitors browse on their end. The platform works best when the sites use a dedicated IP, but owing to the fact that our dedicated servers come with three free IPs, you’ll have everything you need.
