Varnish is a web application accelerator, which has been gaining a lot of popularity in recent years, because it can increase the speed of any Internet site, sometimes even by 100 percent, depending on the content. This tool is sometimes called a caching HTTP reverse proxy as well and is used to lower the overall load on the physical server and to increase the browsing speed for the website visitors. Anytime a visitor accesses a page on a specific Internet site, the web browser request is taken care of by the web server and the requested content is sent as a reply. If Varnish is enabled, it caches the pages that the website visitor opens and if any of them is loaded once more, it’s fetched by Varnish and not by the web server directly. The improvement in the performance is due to the fact that the accelerator handles the web requests significantly quicker than any web server, which leads to much faster browsing speeds for the users. In case any data is changed in the meantime, the cached web pages will also be updated the next time someone tries to access them.
Varnish in Web Hosting
You can unleash Varnish’s potential and boost the speed of your websites irrespective of the web hosting package that you’ve picked and you can activate and set up the data caching platform with a couple of clicks of the mouse via the easy-to-work-with graphical interface offered by our advanced Hepsia Control Panel. In the meantime, you will be able to select two separate things – how many sites will use the Varnish platform, in other words – the number of instances, and how much info will be cached, i.e. the amount of memory. The latter is offered in increments of 32 MB and is not linked to the number of instances, so you can add more instances with less memory and vice versa. If you’ve got lots of content on a specific Internet site and you get many visitors, more memory will guarantee you better results. You may also consider employing a dedicated IP address for the websites that will use the Varnish platform. The Hepsia Control Panel will provide you with easy 1-click controls for disabling or rebooting any instance, for deleting the cache associated with any site and for viewing comprehensive logs.
Varnish in Semi-dedicated Servers
All our Linux semi-dedicated servers include Varnish by default, so you can make full use of the web accelerator tool and boost the load speed of any site that you host on our platform. You will get 64 megabytes of memory exclusively for Varnish at no extra cost and you can add an instance with no more than a few clicks of the mouse through the Hepsia hosting Control Panel, which is included with the semi-dedicated server plans. In case you want more memory, the latter is offered in increments of 32 MB in the Control Panel’s Upgrades section and it will be at your disposal momentarily. You can also add more instances as an upgrade, so you can choose whether a lot of data will be cached for one site or whether the available memory will be used by different websites. The Hepsia Control Panel will enable you to restart or to remove any instance, to see the system log for it or to clear the cached files using one-click controls. To take full advantage of Varnish, you can assign a dedicated IP address to the sites which will employ it.
Varnish in VPS Servers
Varnish is included by default with all VPS servers offered by our company given that the VPS is ordered with the Hepsia Control Panel, so you can improve the performance of your sites with only a couple of clicks. The more powerful the plan, the more system memory Varnish will have at its disposal, but even with a low-end plan, the caching platform will be able to utilize several hundred megabytes, so even if you own a number of sites, you will notice an immense decrease in the overall server load and a considerably faster page load speed. The Varnish platform will need to work for a while while the visitors browse the site and as soon as the content has been cached, you will perceive the effect. One of the benefits of using Varnish is that a less powerful and less pricey package will accomplish the same job as a more high-priced one without the caching platform, so not only will your Internet sites perform better, but you will also spare a certain amount of money.
Varnish in Dedicated Servers
All Linux dedicated servers that are ordered with the in-house built Hepsia website hosting Control Panel come with Varnish, which is one of the pre-installed platforms that you’ll get with the machine. The Varnish platform can be set up and administered without any effort through the Hepsia Control Panel’s easy-to-use GUI and, with no more than one mouse click, you can check an in-depth log, create or reboot an instance, clear the cached files for any website and much, much more. Shortly after you configure the Varnish platform for a given domain or subdomain, it will begin caching the web pages opened by the site visitors and once it has cached enough content, you’ll witness a significantly faster website performance plus a reduced load on the machine. With Varnish-dedicated system memory starting at 3 gigabytes, you’ll be able to use the software platform for workload distribution purposes even if you host lots of Internet sites on your server.
