Varnish is a data caching platform, which is sometimes called an HTTP reverse proxy. It is a web app accelerator tool that can improve the speed of a website by up to one thousand percent, depending on the content itself. Whenever a visitor opens any page on a site that uses Varnish, the platform caches the page and delivers it instead of the web server in case the visitor opens it again. Thus, the web browser request from the visitor is not handled by the server and the web page will load considerably faster, as the Varnish caching platform can serve data many times faster than any web server software. The result will be a considerably faster loading site, which means a much-improved browsing experience. If any of the cached web pages is updated on the actual website, the data that Varnish caches in its memory is ‘refreshed’ too, so the site visitors won’t see old content.
Varnish in Cloud Web Hosting
If you host your websites under a cloud web hosting account with us, you’ll be able to add Varnish with a few mouse clicks from your Control Panel. The content caching platform comes as an optional upgrade with all our shared 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 content. The two features that can be upgraded in the Control Panel’s Upgrades section are the number of instances and the amount of system memory and they aren’t directly linked to each other, so you can decide whether you need a lot of memory for one single large website or less memory for several smaller ones. You can use the full potential of Varnish if the websites use a dedicated IP address. Using the Control Panel, you can swiftly start/restart/remove an instance, delete the cached files independently for each site which uses the Varnish platform or view a detailed system log.
Varnish in Semi-dedicated Servers
All our Linux semi-dedicated servers include Varnish by default, so you can make use of the web accelerator tool and accelerate the load speed of any site that you host on our platform. You will get 64 MB of memory particularly for the Varnish accelerator at no additional fee and you’ll be able to enable an instance with no more than a few clicks from the Hepsia hosting Control Panel, which comes with the semi-dedicated packages. In case you need more memory, the latter is offered in increments of 32 megabytes through the Control Panel’s Upgrades section and it will be available to you immediately. You can also add more instances as a separate upgrade, so you can decide if plenty of content will be cached for a single website or if the memory will be utilized by several websites. Hepsia will permit you to restart or to discontinue any instance, to check the system log file associated with it or to clear the cached content using one-click buttons. To get the most out of Varnish, you can assign a dedicated IP to the sites that will employ it.
Varnish in VPS Servers
The Varnish platform comes by default with all Linux VPS servers offered by us on the condition that the server is ordered with the Hepsia hosting Control Panel, so you can improve the overall performance of your sites with just a couple of clicks of the mouse. The more powerful the plan, the more memory will be available to Varnish, but even with a low-end package, the caching platform will be able to utilize several hundred megabytes, so even if you’ve got a number of Internet sites, you’ll notice an enormous reduction in the server load and a considerably faster web page load speed. The Varnish platform will have to work for a little while as the visitors navigate the pages and as soon as the content has been cached, you’ll distinguish the results. One of the pros of using Varnish is that a lower-end and less costly Virtual Private Server plan will accomplish the very same job as a more pricey one without the platform, so not only will your sites perform significantly better, but you’ll also save some cash.
Varnish in Dedicated Servers
You can employ Varnish in order to enhance the loading speed of any site that is hosted on a dedicated server with us when the Hepsia Control Panel is installed on the machine. Not only will you get the caching platform ready to be used at no additional charge, but you’ll also have full control over it via Hepsia’s easy-to-use GUI. It’ll take just one single click to start or delete an instance or to clear the cache associated with any website that is using the Varnish platform and if you’re more advanced, you can also see the platform’s logs. Varnish comes with at least 3 GB of virtual memory for web content caching purposes, so even in case you host multiple websites on your server and they all use the caching platform, the difference in their performance will be observable. You will only have to wait for a little while until Varnish caches whatever webpages the website visitors browse on their end. The platform works best when the Internet sites use a dedicated IP address, but since our servers include 3 cost-free IP addresses, you’ll have all that you need.
