Varnish is a content caching platform, which is occasionally called a caching HTTP reverse proxy. It is a web application accelerator that can improve the loading speed of a website by up to one thousand percent, based on the content itself. Every time a visitor opens any page on a website that uses Varnish, the platform caches the page and delivers it instead of the web server in case the visitor loads it again. Thus, the browser request from the visitor is not handled by the web server and the page will load significantly faster, as the Varnish platform can serve content many times faster than any web server software. The end result is a substantially faster loading page, which leads to an enormously improved website browsing experience. In case any of the cached pages is updated on the actual Internet site, the data that Varnish keeps in its memory is ‘refreshed’ too, so the users will never see out-of-date data.
Varnish in Website Hosting
If you host your sites in a website hosting account with our company, you’ll be able to activate Varnish with a few mouse clicks via your Control Panel. The data caching platform is available as an upgrade with all our packages and you can choose the number of the websites that will use it and the total amount of system memory that will be used for the cached data. The two features that can be upgraded in the Control Panel’s Upgrades section are the amount of system memory and the number of instances and they aren’t directly linked to each other, so you can decide if you need plenty of memory for one single large-size website or less memory for multiple smaller ones. You can take advantage of the full potential of Varnish if the sites use a dedicated IP address. With the hosting Control Panel, you can easily start/restart/terminate an instance, clear the cached contents independently for each site that uses the Varnish platform or check a detailed log file.
Varnish in Semi-dedicated Servers
All our semi-dedicated servers include Varnish by default, so you can make use of the web app accelerator tool and accelerate the speed of any website that you host on our semi-dedicated servers. You will get 64 megabytes of memory exclusively for Varnish at no extra fee and you can activate an instance with no more than a couple of mouse clicks via the Hepsia Control Panel, which is included with the semi-dedicated packages. If you need more memory, the latter is available in increments of 32 MB through the Upgrades section of the Control Panel and it will be at your disposal instantly. You can also order more instances as a separate upgrade, so you can choose whether plenty of content will be cached for a single site or whether the memory will be utilized by multiple sites. Hepsia will permit you to restart or to cancel any instance, to check the system log for it or to clear the cached data using single-click buttons. To get the most out of the Varnish accelerator, you can get a dedicated IP address for the Internet sites which will use it.
Varnish in Dedicated Servers
You can employ Varnish to optimize the speed of any website that’s hosted on a dedicated server from our company if the Hepsia hosting Control Panel is pre-installed on it. Not only will you get the platform ready for use at no additional fee, but you will also exert total control over it through Hepsia’s simple-to-use graphical interface. It’ll take only one single click of the mouse to start or deactivate an instance or to delete the cached content for any website that is using the Varnish platform and in case you are more competent, you can also see the platform’s logs. Varnish comes with at least 3 GB of virtual memory for website content caching purposes, so even if you run a large number of sites on your dedicated server and they all use the Varnish platform, the difference in their performance will be evident. You will just need to wait for a while till Varnish caches whatever content the website visitors load on their end. The Varnish platform performs best if the sites use a dedicated IP address, but considering the fact that our dedicated servers include 3 free IPs, you’ll have all that you need.
