Varnish is a web accelerator platform, which caches content for faster access. It’s occasionally called an HTTP reverse proxy too and it works between a web server and a web browser. When a site visitor opens a certain web page, its content is requested by the Internet browser, and then the web server handles this browser request and delivers the needed information. If Varnish is activated for a specific website, it will cache its pages on the first request and in case the user opens a cached page again, the content will be delivered by the accelerator platform instead of the server. The improved speed is an end result of the significantly faster response time that Varnish offers as compared to any server software. At the same time, this doesn’t mean that the site visitors will continue seeing the same content again and again, because any change on any of the web pages is reflected in the content that the Varnish platform saves in its system memory.
Varnish in Cloud Hosting
You can make use of Varnish’s full potential and improve your websites’ load speed irrespective of the cloud hosting plan that you have chosen and you can activate and configure the platform with a couple of clicks of the mouse through the easy-to-work-with GUI offered by our next-generation Hepsia Control Panel. In the meantime, you will be able to choose two separate things – how many websites will employ Varnish, i.e. the number of instances, and how much information will be cached, in other words – the amount of system memory. The latter is offered in increments of 32 megabytes and is not tied to the number of instances, so you can order more instances with less memory and the other way around. In case you’ve got plenty of content on a particular Internet site and you gain a lot of visitors, more memory will guarantee you a better result. You may also consider employing a dedicated IP address for the Internet sites that will use Varnish. Hepsia will provide you with simple 1-click controls for switching off or restarting any instance, for deleting the cache associated with any site and for checking exhaustive logs.
Varnish in Semi-dedicated Hosting
All our semi-dedicated packages come with Varnish by default, so you can use the web application accelerator tool and enhance the loading speed of any site that you host on our semi-dedicated servers. You’ll get 64 megabytes of memory particularly for the Varnish accelerator at no additional fee and you will be able to activate an instance with no more than a few mouse clicks via the Hepsia Control Panel, which is included with the semi-dedicated plans. If you need more memory, the latter is available in increments of 32 MB through the Control Panel’s Upgrades section and it will be at your disposal immediately. You can also order more instances as an upgrade, so you can choose whether lots of content will be cached for one website or if the available memory will be utilized by different Internet sites. The Hepsia Control Panel will permit you to restart or to disable any instance, to check the system log file for it or to delete the cached files using 1-click controls. To get the most out of the Varnish accelerator, you can set a dedicated IP address for the websites that will employ it.
Varnish in VPS
We provide Varnish with all of the Hepsia-managed VPS, so in case you obtain a server with this web hosting Control Panel, you will be able to take advantage of the caching platform at no extra cost. Varnish can utilize different amounts of memory for data caching purposes depending on the specific server configuration that you’ve chosen at signup, but at any rate, this amount won’t be less than several hundred MB. This is more than enough to boost the work of a number of large-scale sites, so the better web page load speeds and the lowered load on your VPS will be noticeable. The effect may not be observable immediately, as Varnish will need some time to cache the website content that people open, but shortly after you activate it, you’ll observe its full potential. This caching platform will allow you to use a lower-end VPS server and to give less money to get the exact same performance you’d get with a more powerful virtual machine without Varnish.
Varnish in Dedicated Hosting
You can use Varnish to improve the speed of any site that’s hosted on a dedicated server from us when the Hepsia hosting Control Panel is installed on it. Not only will you get the content caching platform ready for use at no extra cost, but you’ll also have full control over it via Hepsia’s easy-to-navigate graphical interface. It’ll take just one single click of the mouse to start or terminate an instance or to delete the cached files for any site that is using the Varnish platform and in case you are more competent, you can also check the platform’s logs. Varnish comes with at least 3 GB of system memory for caching purposes, so even in case you run an enormous number of sites on your machine and they all use the platform, the improvement in their overall performance will be detectable. You’ll just have to wait for a little while until Varnish caches whatever pages the visitors access on their end. The Varnish platform works best when the websites use a dedicated IP address, but due to the fact that our servers come with 3 cost-free IP addresses, you will have everything you need.
