Varnish is a web app accelerator platform, which caches information for the sake of faster response times. It’s occasionally called an HTTP reverse proxy too and it interacts between a web server and a web browser. When a visitor accesses a particular page, the content is requested by the Internet browser, and then the web server processes this request and sends back the needed info. If Varnish is activated for a certain website, it will cache the pages on the first visit and if the user visits a cached page for a second time, the content will be delivered by the accelerator platform and not by the web server. The improved load speed is an end result of the much faster response speed that Varnish offers as compared to any web server software. Of course, this does not mean that the users will continue being served the exact same content over and over again, as any modification on any of the pages is reflected in the content that Varnish keeps in its memory.

Varnish in Hosting

You can unlock Varnish’s potential and boost your sites’ loading speed regardless of the hosting plan that you have chosen and you can enable and configure the content caching platform with several clicks from the easy-to-use interface offered by our next-gen Hepsia hosting Control Panel. During the procedure, you will be able to select two separate things – how many Internet sites will employ the Varnish platform, in other words – the number of instances, and how much content will be cached, in other words – the amount of memory. The latter comes in increments of 32 MB and is not tied to the number of instances, so you can add more instances with less memory and the other way around. If you’ve got a lot of content on a given website and you draw numerous website visitors, more system memory will guarantee you better results. You may also consider using a dedicated IP for the websites that will use the Varnish caching platform. The Hepsia Control Panel will offer you easy 1-click buttons for discontinuing or rebooting any instance, for erasing the cache for any website and for seeing detailed system logs.

Varnish in Semi-dedicated Servers

The semi-dedicated servers that we’re offering will permit you to employ Varnish once your brand new semi-dedicated account has been activated, since the data caching platform comes by default. 64 megabytes of system memory will be allocated to Varnish the second your account is enabled, so you can make use of this workload balancing software once your website has been taken online. If you’re in need of more memory, you can order 32 megabytes at a time from the Upgrades section of the Hepsia Control Panel and it will be assigned to your semi-dedicated server momentarily. You can also increase the number of the sites that use Varnish, or the so-called ‘instances’, which are not linked directly to the amount of memory that you use, which means that you’ll have more versatility. The caching platform will considerably reduce the load on the semi-dedicated machine that your websites cause, so your website visitors can enjoy fast-opening web pages. You’ll be able to manage the Varnish platform without efforts through the Control Panel using fast-access controls. You’ll be able to start/cancel any of the instances that you have, to delete the cached content for any of your Internet sites or to check system log files.

Varnish in VPS Servers

Varnish comes by default with each of the VPS servers offered by our company as long as the server is ordered with the Hepsia Control Panel, so you can optimize the overall performance of your sites with only a few clicks of the mouse. The more powerful the package, the more system memory will be available to Varnish, but even with a lower-end package, the platform will be able to utilize several hundred megabytes, so even if you have several different Internet sites, you’ll notice a great reduction in the overall server load and a considerably better webpage loading speed. The Varnish platform will need to work for a while as the users browse the pages and as soon as the website content has been cached, you’ll observe the result. One of the upsides of using Varnish is that a less powerful and less expensive Virtual Private Server package will accomplish the same job as a more high-priced one without the caching platform, so not only will your websites perform significantly better, but you’ll also save a certain amount of money.

Varnish in Dedicated Servers

All Linux dedicated servers which are ordered with the custom-built Hepsia hosting Control Panel include Varnish, which is one of the pre-installed platforms that you will get with the dedicated server. The Varnish platform can be set up and managed without effort from Hepsia’s simple-to-work-with interface and, with no more than one click of the mouse, you can check an elaborate log, create or restart an instance, delete the cache for any website and much, much more. Soon after you configure the Varnish platform for a given domain or subdomain, it will begin caching the web pages browsed by the website visitors and as soon as it has cached enough web content, you will witness a tremendously faster website performance plus a decreased load on your dedicated machine. With Varnish-dedicated memory starting at 3 gigabytes, you’ll be able to use the platform for load balancing purposes even if you host a huge number of Internet sites on the dedicated machine.
