Varnish is a web application accelerator platform, which caches information for the sake of faster access. It’s occasionally referred to as an HTTP reverse proxy too and it interacts between a web server and its users. When a visitor opens a particular page, its content is requested by the web browser, and then the web server handles this request and sends back the needed content. If Varnish is activated for a specific website, it will cache the pages on the first request and if the user opens a cached page once more, the information will be delivered by the caching platform and not by the web server. The accelerated loading speed is an end result of the substantially faster response time that the Varnish platform offers compared to any web server software. At the same time, this doesn’t mean that the site visitors will continue seeing the same content over and over again, because any change on any of the pages is reflected in the content that the Varnish platform keeps in its system memory.
Varnish in Shared Hosting
You can take advantage of Varnish’s potential and boost your websites’ loading speed regardless of the shared hosting
package that you have selected and you can activate and configure the content caching platform with several clicks using the easy-to-work-with interface offered by our leading-edge Hepsia hosting Control Panel. During the process, you’ll be able to select two different things – how many sites will employ the Varnish caching platform, i.e. the number of instances, and how much data will be cached, in other words – the amount of memory. The latter comes in increments of 32 MB and is not bound to the number of instances, so you can add more instances with less memory and the other way around. If you’ve got a lot of content on a particular site and you win many site visitors, more memory will guarantee you better results. You may also consider using a dedicated IP for the websites that will use the Varnish caching platform. Hepsia will provide you with simple one-click controls for shutting down or rebooting any instance, for clearing the cache associated with each Internet site and for checking elaborate logs.
Varnish in Semi-dedicated Hosting
Varnish is included in the standard service set that you will obtain when you choose to host your Internet sites in a semi-dedicated server
account. You can enable it for any of your websites through our cutting-edge Hepsia Control Panel. The default memory that the Varnish platform can use to cache data is 64 MB, but in case you decide that you want more, you can upgrade this amount of memory from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, in other words – the number of the Internet sites that can use this caching platform at the same time. As these two things are not tied to each other, you can use a couple of instances with the default amount of memory or you can get more memory in increments of 32 megabytes and use all of it for a single web site. The Varnish caching platform performs best when you assign a dedicated IP address to the Internet sites that utilize its power. Hepsia will offer you a simple way of restarting any instance. Furthermore, you will be able to delete the cached content with just one click.
Varnish in VPS Hosting
We provide Varnish with all of the Hepsia-equipped Linux VPS hosting packages
, so in case you purchase a VPS with this hosting Control Panel, you’ll be able to use the content caching platform at no additional cost. Varnish can utilize different amounts of memory for caching purposes depending on the specific package that you’ve chosen on the order form, but at any rate, this amount will not be less than several hundred MB. This is quite enough to boost the overall performance of a number of traffic-heavy websites, so the faster page load speeds and the decreased load on the virtual machine will be perceivable. The effect may not be obvious momentarily, as Varnish will need a certain amount of time to cache the website content that people open, but shortly after you activate it, you’ll witness its full capacity. This platform will allow you to use a less powerful Virtual Private Server and to give less money to get the very same performance you’d get with a more powerful machine without Varnish.
Varnish in Dedicated Web Hosting
In case you order a dedicated server
with the Hepsia hosting Control Panel, you will get the Varnish data caching platform at no additional cost and you’ll have full control over it through a rather easy-to-use GUI – you’ll be able to start, to disable or to reboot an instance, to see an exhaustive system log, to clear the cached content for any website and much, much more. Varnish will have several gigabytes of system memory at its disposal, so even if you run heavy websites with numerous visitors, you’ll notice the substantially faster page load times and the reduced load on the server. This will happen soon after you start using the Varnish platform, as it will need a certain amount of time to cache the pages that people open. You can make the most of the platform’s capability in case the websites that are using it also use a dedicated IP, but owing to the fact that your server includes a few IP addresses by default, you will not need to pay anything on top of your monthly fee for the machine itself.
