Varnish is a web application accelerator, which has been gaining a lot in popularity lately, as it can increase the loading speed of any Internet site, at times even by 100 percent, based on the content. This tool is occasionally called an HTTP reverse proxy as well and is used to decrease the overall load on the physical server and to improve the browsing speed for the website visitors. Whenever a visitor loads a page on a particular website, the web browser request is handled by the web server and the requested content is sent as a reply. If Varnish is activated, it caches the web pages that the site visitor browses and in case any of them is accessed for a second time, it is fetched by Varnish and not by the web server directly. The increase in the overall performance comes from the fact that the accelerator handles the web requests considerably quicker than any web server, which results in much faster browsing speeds for the website visitors. If any data is updated meanwhile, the cached pages will also be updated the next time somebody tries to access them.

Varnish in Cloud Web Hosting

Varnish is available as an optional upgrade with each and every Linux cloud web hosting and if you would like to use it, you can add it to your shared hosting account using the Upgrades menu in your Hepsia hosting Control Panel. There are two separate features that can be upgraded – the number of instances and the system memory. The first one depends on the number of the Internet sites that you want to use Varnish for, whereas the second, which is available in increments of 32 megabytes, pertains to the maximum amount of content that the content caching platform can cache at any particular time. The Hepsia Control Panel’s intuitive GUI will enable you to shut down or to reboot any instance, to check in-depth logs or to delete the platform’s cache with just a click. For optimum results, you can use a dedicated IP for the websites that will use the platform. With Varnish, your site will load significantly faster, meaning more happy site users and prospective customers.

Varnish in Semi-dedicated Hosting

Varnish is included in the default set of services that you will receive when you decide to host your Internet sites in a semi-dedicated server account. You can activate it for any of your websites through our avant-garde Hepsia Control Panel. The default memory that the Varnish caching platform can use to cache content is 64 megabytes, but in case you decide that you need more, you can upgrade this amount of memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, in other words – the number of the websites that can use this platform at the same time. Since these two features are not linked to each other, you can use a couple of sites with the default memory or you can order more memory in increments of 32 MB and use all of it for a single website. The Varnish caching platform performs best when you use a dedicated IP for the websites that utilize its power. Hepsia will provide you with an easy means of restarting any instance. Furthermore, you’ll be able to clear the cached content with just one single click.

Varnish in Dedicated Servers Hosting

All Linux dedicated servers hosting that are ordered with the custom-developed Hepsia website hosting Control Panel come with Varnish, which is among the pre-installed platforms that you’ll get with the server. The Varnish caching platform can be configured and administered without any effort via the Hepsia Control Panel’s user-friendly graphical interface and, with no more than one single mouse click, you can see an exhaustive log, add or reboot an instance, clear the cached content associated with any site and much more. Shortly after you configure the Varnish platform for a certain domain or sub-domain, it will start caching the webpages browsed by the website visitors and as soon as it has cached enough content, you’ll observe a significantly faster site performance as well as a reduced load on the server. With Varnish-dedicated virtual memory starting at three gigabytes, you will be able to use the software platform for load distribution purposes even if you run a vast number of websites on your dedicated machine.
