Varnish is a web app accelerator, which has been gaining a lot of popularity lately, because it can increase the load speed of any website, at times even by 100 percent, depending on the content. This tool is occasionally called an HTTP reverse proxy too and is used to decrease the overall load on the physical machine and to improve the browsing speed for the website visitors. Every time a visitor opens a page on a given site, the browser request is handled by the web server and the requested info is served as a reply. If Varnish is activated, it caches the web pages that the visitor browses and if any of them is loaded for a second time, it’s delivered by Varnish and not by the web server directly. The increase in the performance is due to the fact that the accelerator processes the web requests tremendously faster than any web server, which leads to much faster browsing speeds for the site visitors. If any data is edited meanwhile, the cached webpages will also be ‘refreshed’ the next time someone attempts to access them.
Varnish in Cloud Website Hosting
In case you host your sites under a cloud website hosting account with our company, you will be able to add Varnish with a couple of clicks of the mouse via your hosting Control Panel. The caching platform is offered as an optional upgrade with all our web hosting plans and you can select the number of the sites that will use it and the maximum 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 memory and they are not tied directly to each other, so you can choose whether you want lots of memory for one single large-size site or less memory for several smaller ones. You can make use of the full potential of Varnish in case the websites use a dedicated IP. Using the Control Panel, you can quickly start/reboot/disable an instance, clear the cached contents individually for each site which uses the Varnish platform or check an elaborate log.
Varnish in Semi-dedicated Servers
All our Linux semi-dedicated servers come with Varnish by default, so you can take advantage of the accelerator and enhance the speed of any site that you host on our platform. You’ll get 64 megabytes of system memory dedicated to the Varnish accelerator at no additional cost and you can activate an instance with no more than a couple of clicks of the mouse via the Hepsia hosting Control Panel, which comes with the semi-dedicated server plans. If you want more memory, the latter is offered in increments of 32 MB in the Upgrades section of the Control Panel and it will be at your disposal right away. You can also order more instances as an upgrade, so you can decide if a lot of content will be cached for one website or whether the available memory will be used by several websites. Hepsia will permit you to reboot or to stop any instance, to see the system log for it or to clear the cached content using one-click controls. To get the most out of the Varnish accelerator, you can get a dedicated IP address for the sites that will employ it.
Varnish in VPS Servers
The Varnish caching platform comes by default with all VPS web hosting service offered by our company given that the Virtual Private Server is ordered with the Hepsia Control Panel, so you can improve the work of your sites with only a couple of clicks of the mouse. The more powerful the plan, the more system memory will be available to Varnish, but even with a low-end package, the platform will be able to utilize several hundred megabytes, so even if you own a number of sites, you will notice a significant reduction in the overall server load and a substantially faster site load speed. The Varnish caching platform will have to work for a while while the users navigate the site and once the content has been cached, you will see the effects. One of the benefits of employing Varnish is that a less powerful and less expensive VPS package will do the exact same job as a more pricey one without the caching platform, so not only will your Internet sites perform considerably better, but you’ll also spare a certain amount of money.
Varnish in Dedicated Servers
In case you order a dedicated server with the Hepsia hosting Control Panel, you’ll get the Varnish caching platform at no additional cost and you will have complete control over it through a quite simple-to-navigate graphical interface – you’ll be able to start, to deactivate or to restart an instance, to browse an elaborate system log, to clear the cached data for any Internet site and much, much more. Varnish will have several gigabytes of memory at its disposal, so even if you host busy websites with plenty of visitors, you’ll notice the tremendously faster web page load times and the less load. This will become a fact shortly after you begin using the Varnish platform, as it will need a certain amount of time to cache the content that visitors browse. You can get the most out of the platform’s capabilities in case the Internet sites that are using it also use a dedicated IP address, but owing to the fact that your dedicated server comes with a couple of IPs by default, you will not need to pay anything on top of your monthly fee for the machine itself.
