Varnish is a content caching platform, which is sometimes referred to as a caching HTTP reverse proxy. It’s a website accelerator tool that can accelerate the load speed of a website by up to 1000%, based on the content itself. Anytime a visitor accesses any page on a website that uses Varnish, the platform caches the page and delivers it instead of the web server when the visitor accesses it again. In this way, the web browser request from the visitor is not handled by the web server and the page will open much faster, since Varnish can deliver information many times faster than any server software. The end result is a considerably faster loading page, which means an enormously improved visitor experience. When any of the cached web pages is updated on the live website, the info that Varnish caches in its memory is ‘refreshed’ as well, so the website visitors won’t end up seeing out-of-date information.
Varnish in Website Hosting
If you host your websites in a website hosting
account with us, you’ll be able to add Varnish with a few clicks through your hosting Control Panel. The content caching platform is available as an optional upgrade with all our hosting plans and you can select how many sites 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 number of instances and the amount of system memory and they aren’t tied directly to each other, so you can decide whether you need lots of memory for one large website or less memory for several smaller ones. You can unlock the full potential of Varnish in case the sites use a dedicated IP address. Using the Control Panel, you can quickly start/reboot/terminate an instance, delete the cached content individually for each website which uses the Varnish platform or check an exhaustive log file.
Varnish in Semi-dedicated Servers
The semi-dedicated servers
that we offer will permit you to employ Varnish once your brand new semi-dedicated account has been opened, since the caching platform is available by default. 64 MB of system memory will be allocated to Varnish the second your account is enabled, so you can take advantage of this workload distribution software as soon as you launch your website. In case you’re in need of more memory, you can add 32 megabytes at a time from the Upgrades section of the Hepsia hosting Control Panel and it will be allocated to your semi-dedicated server right away. You can also increase the number of the Internet sites that employ Varnish, or the so-called ‘instances’, which are not directly bound to the amount of memory that you use, which means that you’ll enjoy more freedom. The caching platform will substantially decrease the load that your websites generate, so your site visitors can enjoy fast-loading pages. You’ll be able to manage Varnish effortlessly through the Hepsia Control Panel using fast-access controls. You’ll be able to start/disable any of the instances that you’ve got, to clear the cache for any of your Internet sites or to check system log files.
Varnish in Dedicated Servers
You can employ Varnish to improve the load speed of any site that is hosted on a dedicated server
from us when the Hepsia hosting Control Panel is installed on the machine. Not only will you get the platform ready for use at no additional cost, but you will also have total control over it via Hepsia’s easy-to-work-with GUI. It’ll take only one click to start or cancel an instance or to clear the cached data for any Internet site that’s using the Varnish platform and in case you’re more competent, you can also see the platform’s system logs. Varnish comes with no less than 3 gigabytes of memory for caching purposes, so even in case you run numerous websites on your dedicated server and they all use the Varnish platform, the improvement in their overall performance will be distinguishable. You’ll simply need to wait for a little while until Varnish caches whatever webpages the visitors open on their end. The platform performs best if the websites use a dedicated IP address, but owing to the fact that our servers come with three free-of-charge IP addresses, you will have everything you need.
