Learn exactly what Varnish is. Get to know a lot more about web accelerators and their function.
Varnish is a website 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 itself. This tool is occasionally called a caching HTTP reverse proxy as well and is used to reduce the overall load on the physical machine and to improve the browsing speed for the site visitors. Every time a visitor loads a page on a specific website, the browser request is taken care of by the web server and the requested data is sent as a response. If Varnish is activated, it caches the pages that the visitor browses and if any of them is accessed once more, it is fetched by Varnish and not by the web server directly. The boost in the performance is due to the fact that the accelerator processes the web requests substantially quicker than any web server, which leads to much faster browsing speeds for the visitors. If any data is updated in the meantime, the cached pages will also be ‘refreshed’ the next time somebody tries to open them.
Varnish in Semi-dedicated Servers
Varnish is a feature, which comes as standard with all semi-dedicated plans
offered by our company and you can use it for load distribution purposes. It’s available in your Hepsia Control Panel. The Varnish data caching platform comes with 64 megabytes of system memory for cached data storing purposes and you can use it with any Internet site that you host in the semi-dedicated server account. If you are in need of more, you can increase the memory quota. The memory itself is offered in increments of 32 megabytes through the Upgrades section of the Control Panel. The exact same Upgrades section will enable you to enable more instances as well, if you wish to use the Varnish platform with multiple sites. The two things can be added independently – you can cache the content of a single resource-demanding Internet site or use a number of websites with the default memory allowance. You can get the most out of the Varnish platform in case you have a dedicated IP address and you can order one with your semi-dedicated plan as well. Hepsia will grant you total control over the caching platform and, with no more than one single click, you will be able to clear the cached data, to see a log or to restart an instance.
Varnish in VPS Servers
We offer Varnish with all Hepsia-equipped VPS web hosting plans
, so in case you purchase a server with this web hosting Control Panel, you will be able to take full advantage of the data caching platform at no additional charge. Varnish can utilize different amounts of memory for content caching purposes based on the very Virtual Private Server package that you’ve chosen on the order form, but in any case, this amount won’t be less than several hundred MB. This is quite enough to enhance the work of a number of busy websites, so the better site load speeds and the decreased server load will be perceivable. The effect may not be distinguishable instantly, since Varnish will require a certain amount of time to cache the content that users access, but shortly after you activate it, you will perceive its full capacity. This caching platform will permit you to use a lower-end VPS server and to pay less money to get the exact same performance you would get with a higher-end machine without Varnish.
Varnish in Dedicated Servers
All dedicated web hosting plans
that are ordered with the in-house developed Hepsia web hosting Control Panel include Varnish, which is among the pre-installed platforms that you’ll get with the dedicated server. The Varnish caching platform can be activated and administered effortlessly through the Hepsia Control Panel’s simple-to-navigate interface and, with no more than one mouse click, you can view an in-depth log, add or restart an instance, delete the cached content associated with any website and much more. Shortly after you activate the Varnish platform for a specific domain or subdomain, it will start caching the webpages opened by your website visitors and as soon as it has cached enough web content, you’ll observe a considerably faster site performance in addition to a decreased load on your dedicated server. With Varnish-dedicated virtual memory starting at 3 GB, you will be able to use the software platform for workload distribution purposes even if you run an enormous number of Internet sites on the dedicated server.
