Varnish is a data caching platform, which is sometimes referred to as a caching HTTP reverse proxy. It is a web application accelerator tool that can boost the load speed of a site by up to 1000%, depending on its content. Whenever a visitor accesses any page on a site that uses Varnish, the platform caches the page and delivers it instead of the web server if the visitor opens it again. In this way, the web browser request from the visitor is not processed by the server and the web page will open considerably faster, since the Varnish platform can serve information many times faster than any server software. The end result will be a significantly faster loading website, which leads to an enormously improved visitor experience. In case any of the cached pages is updated on the live Internet site, the data that Varnish keeps in its memory is ‘refreshed’ too, so the website visitors won’t end up seeing outdated info.
Varnish in Cloud Website Hosting
Varnish comes as an optional upgrade with each Linux cloud website hosting and if you’d like to use it, you can add it to your web hosting account using the Upgrades menu in your Hepsia Control Panel. There are two different features that can be upgraded – the number of instances and the memory. The first one pertains to the number of the Internet sites that you wish to use Varnish for and the second one, which is offered in increments of 32 MB, pertains to the total amount of data that the platform can cache at any particular time. Hepsia’s easy-to-work-with GUI will permit you to terminate or to reboot any instance, to see elaborate logs or to get rid of the platform’s cache with just click of the mouse. For optimal results, you can employ a dedicated IP address for the websites that will use the platform. With Varnish, your Internet site will open tremendously faster, which means more happy visitors and potential clients.
Varnish in Semi-dedicated Servers
The Varnish caching platform is included in the default service set that you’ll acquire if you decide to host your Internet sites in a semi-dedicated server account. You can enable it for any of your Internet sites via our innovative Hepsia Control Panel. The default amount of system memory that the Varnish platform can use to cache content is 64 megabytes, 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, in other words – the number of the sites that can use this caching platform at the same time. As these two features aren’t bound to each other, you can use several websites with the default memory or you can order more memory in increments of 32 MB and use all of it for a single site. The Varnish platform works best when you get a dedicated IP address for the websites that utilize its power. The Hepsia Control Panel will give you a simple means of restarting any instance. What’s more, you’ll be able to clear the cached data with just one mouse click.
Varnish in VPS Servers
The Varnish data caching platform is included by default with each of the Linux VPS servers that we are offering as long as the VPS is ordered with the Hepsia Control Panel, so you can boost the overall performance of your websites with just a few 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 caching platform will be able to utilize several hundred megabytes, so even if you manage a handful of Internet sites, you’ll notice a significant decrease in the overall server load and a tremendously better webpage loading speed. The Varnish platform will have to work for a while while the users navigate the website and as soon as the site content has been cached, you’ll see the results. One of the pros of using Varnish is that a lower-end and less expensive VPS package will do the very same job as a more expensive one without the platform, so not only will your websites work better, but you’ll also spare some cash.
Varnish in Dedicated Servers
All Linux dedicated servers that are ordered with the in-house built Hepsia web hosting Control Panel come with Varnish, which is among the pre-installed software platforms that you will get with the dedicated server. The Varnish data caching platform can be configured and administered without effort through the Hepsia Control Panel’s user-friendly GUI and, with no more than a click, you can view an in-depth log, add or restart an instance, clear the cached files for any website and much, much more. Shortly after you activate Varnish for a certain domain or sub-domain, it will start caching the pages loaded by your site visitors and once it has cached enough content, you will witness a tremendously faster site performance and a lowered server load. With Varnish-dedicated system memory starting at 3 gigabytes, you’ll be able to use the platform for load balancing purposes even if you run many sites on the dedicated server.
