Varnish is a web accelerator, which has been gaining a lot of popularity lately, because it can increase the load speed of any website, at times even by one hundred percent, based on the content. This tool is sometimes called an HTTP reverse proxy as well and is used to decrease the overall load on the physical machine and to increase the browsing speed for the site visitors. Every time a visitor opens a page on a specific site, the browser request is processed by the web server and the requested data is sent as a response. If the Varnish accelerator is activated, it caches the web pages that the website visitor opens and if any of them is loaded again, it is fetched by Varnish and not by the web server directly. The performance boost comes from the fact that the accelerator handles the web requests tremendously quicker than any web server, which results in much faster browsing speeds for the users. In case any data is modified meanwhile, the cached webpages will also be ‘refreshed’ the next time somebody attempts to access them.
Varnish in Cloud Hosting
Varnish is offered as an optional upgrade with each of our Linux cloud packages. You can add it to your web hosting account from the Hepsia Control Panel, which is available with all shared hosting packages and you’ll get a really simple-to-use GUI, which will grant you complete control over the content caching system. Using one-click fast-access buttons, you can reboot or delete any of the instances, in other words – Varnish will no longer work for a certain Internet site. You can also check a comprehensive log file or erase the cache associated with any of the sites. When you add Varnish to your web hosting plan, you will be able to choose the total amount of system memory that will be at your disposal for content caching purposes and how many sites will use Varnish. You can always add more memory in increments of 32 MB and, for optimum performance, you can set a dedicated IP address for the sites that will use Varnish. This will permit you to take full advantage of your Internet sites and to have numerous satisfied site visitors.
Varnish in Semi-dedicated Hosting
All our Linux semi-dedicated packages include Varnish by default, so you can take full advantage of the web accelerator and improve the loading speed of any website that you host on our semi-dedicated servers. You will get 64 MB of system memory exclusively for Varnish at no extra charge and you can add an instance with no more than a couple of clicks of the mouse from the Hepsia hosting Control Panel, which is included with the semi-dedicated server plans. In case you need more memory, the latter is available in increments of 32 megabytes in the Control Panel’s Upgrades section and it will be at your disposal instantaneously. You can also order more instances as an upgrade, so you can decide whether a lot of data will be cached for a single website or if the memory will be utilized by different Internet sites. The Hepsia Control Panel will permit you to reboot or to shut down any instance, to view the system log file associated with it or to delete the cached files using 1-click buttons. To take full advantage of Varnish, you can set a dedicated IP for the Internet sites that will use it.
Varnish in Dedicated Web Hosting
If you order a dedicated server with the Hepsia hosting Control Panel, you’ll acquire the Varnish caching platform at no extra charge and you will exert full control over it via an incredibly easy-to-work-with graphical interface – you will be able to start, to delete or to reboot an instance, to check a comprehensive log, to clear the cached content for any Internet site and much, much more. The Varnish platform will have several GB of memory at its disposal, so even if you own large-sized Internet sites with an immense number of visitors, you’ll notice the much faster web page load times and the less load on your server. This will become a fact shortly after you start using the Varnish platform, as it will require some time to cache the content that visitors open. You can get the most out of the platform’s capacity if the sites that are using it use also a dedicated IP address, but considering the fact that your dedicated server includes a couple of IPs by default, you won’t need to pay anything on top of your monthly fee for the server itself.
