Varnish is a website accelerator platform, which caches information for quicker access. It is occasionally referred to as a caching HTTP reverse proxy too and it works between a web server and a web browser. When a website visitor loads a certain webpage, 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 particular website, it will cache its pages on the first visit and if the user accesses a cached page again, the information will be delivered by the caching platform instead of the web server. The boosted speed is an end result of the considerably faster response speed that Varnish offers as compared to 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, since any modification on any of the pages is reflected in the content that the Varnish platform caches in its system memory.

Varnish in Shared Hosting

You can take advantage of Varnish’s potential and accelerate the load speed of your sites regardless of the shared hosting package 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 interface offered by our cutting-edge Hepsia hosting Control Panel. During the procedure, you’ll be able to choose two separate things – how many websites will employ the Varnish caching platform, in other words – the number of instances, and how much information will be cached, i.e. the amount of system memory. The latter is available in increments of 32 megabytes and is not linked to the number of instances, so you can order more instances with less memory and the other way around. If you’ve got a lot of content on a given website and you receive a lot of site visitors, more memory will guarantee you better results. You may also consider employing a dedicated IP address for the Internet sites that will use the Varnish caching platform. The Hepsia Control Panel will provide you with simple 1-click buttons for switching off or restarting any instance, for erasing the cache associated with each Internet site and for seeing exhaustive system logs.

Varnish in Semi-dedicated Servers

The Varnish content caching platform is included in the default service set that you will acquire if you decide to host your sites in a semi-dedicated server account. You can activate it for any of your sites through our next-generation Hepsia Control Panel. The default amount of system memory that Varnish can use to cache data is 64 megabytes, but in case you decide that you want 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 websites that can use this caching platform at the same time. As these two things are not bound to each other, you can use a few instances with the default amount of memory or you can add more memory in increments of 32 MB and use all of it for one single site. The Varnish platform works best if you use a dedicated IP address for the sites that utilize its power. Hepsia will provide you with a simple way of rebooting any instance. On top of that, you’ll be able to clear the cached contents with only a click.

Varnish in VPS Servers

You can take full advantage of the load balancing capabilities of Varnish with each of our VPS servers if you select Hepsia as your Control Panel. The data caching platform is offered by default and the memory that it will be able to use to cache the content of your sites is dependent upon the specific Virtual Private Server package that you’ve chosen, but even with the less powerful packages, you will have at least several hundred MB of memory at your disposal solely for data caching purposes. This amount is sufficient to improve the work of multiple sites. It’ll take some time for you to see the effects, since the Varnish platform caches the content that site visitors access, but shortly thereafter you will notice the substantially reduced server load and the enhanced site loading speed. The Varnish caching platform will permit you to use a lower-end VPS plan for sites that would normally require a more pricey hosting solution.

Varnish in Dedicated Servers

You can employ Varnish to accelerate the load speed of any website that’s 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 data caching platform ready for use at no extra cost, but you’ll also have complete control over it through Hepsia’s simple-to-work-with GUI. It’ll take just one click of the mouse to start or discontinue an instance or to clear the cached content associated with any website that is using Varnish and in case you are more experienced, you can also browse the platform’s logs. Varnish comes with at least 3 GB of virtual memory for web content caching purposes, so even if you run plenty of sites on your dedicated server and they all use the Varnish caching platform, the improvement in their overall performance will be apparent. You will simply have to wait for a while till Varnish caches whatever webpages the site visitors open on their end. The platform performs best when the websites use a dedicated IP address, but owing to the fact that our dedicated servers include three free-of-charge IP addresses, you will have all that you need.
