Varnish is a web application accelerator tool, which has been gaining a lot in popularity lately, because it can increase the speed of any site, sometimes even by one hundred percent, depending on the content itself. This tool is occasionally referred to as a caching HTTP reverse proxy too and is used to reduce the overall load on the physical server and to enhance the access speed for the site visitors. Anytime a visitor loads a page on a certain website, the web browser request is handled by the web server and the requested info is returned as a reply. If the Varnish accelerator is activated, it caches the web pages that the visitor opens and in case any of them is opened again, it is served by Varnish and not by the web server directly. The increase in the overall performance is due to the fact that the accelerator processes the browser requests tremendously faster than any web server, which results in much faster browsing speeds for the website visitors. If any data is modified meanwhile, the cached pages will also be updated the next time somebody attempts to open them.
Varnish in Cloud Website Hosting
Varnish is available as an optional upgrade with each of our Linux cloud website hosting. You can add it to your account through the Hepsia hosting Control Panel, which comes with all shared hosting packages and you’ll get a quite easy-to-use GUI, which will grant you complete control over the content caching system. Using one-click fast-access controls, you can reboot or disable any of the instances, i.e. Varnish will no longer be activated for a specific Internet site. You can also check an exhaustive log file or erase the cache associated with any of the Internet sites. When you add Varnish to your web hosting plan, you’ll be able to select the maximum amount of system memory that will be at your disposal for content caching purposes and the number of the sites that will use Varnish. You can always get more memory in increments of 32 megabytes and, for optimum performance, you can set a dedicated IP for the websites that will use Varnish. This will permit you to take full advantage of your sites and to have plenty of happy site visitors.
Varnish in Semi-dedicated Hosting
The Varnish content caching platform is part of the basic set of services that you’ll receive if you decide to host your sites under a semi-dedicated server account. You can enable it for any of your Internet sites through our cutting-edge Hepsia hosting Control Panel. The default system memory that Varnish can use to cache content is 64 MB, but in case you decide that you need more, you can upgrade this memory from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, i.e. the number of the sites that can use this caching platform simultaneously. As these two features aren’t bound to each other, you can use a few websites with the default amount of memory or you can order more memory in increments of 32 megabytes and use all of it for a single website. The Varnish caching platform performs best when you use a dedicated IP address for the websites that utilize its power. Hepsia will offer you an easy means of rebooting any instance. What’s more, you’ll be able to delete the cached files with just one single click of the mouse.
Varnish in VPS
Varnish comes by default with each of the Linux VPS packages that we offer as long as the Virtual Private Server is ordered with the Hepsia hosting Control Panel, so you can optimize the work of your sites with just a couple of clicks of the mouse. The more powerful the package, the more system memory Varnish will have at its disposal, but even with a less powerful package, the platform will be able to utilize several hundred MB, so even if you run several websites, you will notice a significant reduction in the server load and a much faster page loading speed. The Varnish platform will have to work for a while while the visitors navigate the pages and once the content has been cached, you will notice the effects. One of the benefits of using Varnish is that a lower-end and less pricey package will do the same job as a more expensive one without the caching platform, so not only will your websites work much better, but you’ll also spare some cash.
Varnish in Dedicated Hosting
If you order a dedicated server with the Hepsia hosting Control Panel, you’ll obtain the Varnish content caching platform at no extra fee and you’ll have complete control over it via an incredibly time and effort saving graphical interface – you’ll be able to start, to discontinue or to restart an instance, to view an elaborate log, to clear the cache associated with any site and much more. The Varnish caching platform will have several gigabytes of virtual memory at its disposal, so even if you manage high-demand websites with a large number of visitors, you will notice the considerably better website load speeds and the less load on your server. This will become a fact soon after you begin using the Varnish platform, as it will require a certain amount of time to cache the site content that visitors request. You can make the most of the platform’s capabilities if the sites that are using it use also a dedicated IP address, but owing to the fact that your server includes a few IP addresses by default, you won’t need to pay anything on top of the monthly fee for the server itself.
