Varnish is a web accelerator, which has been gaining a lot in popularity lately, as it can increase the speed of any Internet site, at times even by 100%, based on the content itself. This tool is occasionally referred to as a caching HTTP reverse proxy as well and is used to reduce the overall server load and to increase the browsing speed for the website visitors. Anytime a visitor opens a page on a certain Internet site, the browser request is taken care of by the web server and the requested information is returned as a reply. If the Varnish accelerator is enabled, it caches the pages that the visitor opens and if any of them is opened once more, it is fetched by Varnish and not by the server directly. The boost in the performance comes from the fact that the accelerator processes the web requests significantly quicker than any web server, which results in much faster browsing speeds for the users. If any data is changed in the meantime, the cached webpages will also be ‘refreshed’ the next time somebody opens them.

Varnish in Cloud Web Hosting

Varnish comes as an optional upgrade with all our cloud web hosting. You can add it to your hosting account through the Hepsia Control Panel, which comes with all shared hosting plans and you’ll get a really easy-to-work-with graphical interface, which will grant you complete control over the caching system. Using one-click quick-access buttons, you can reboot or deactivate any of the instances, i.e. Varnish will no longer work for a specific Internet site. You can also view an exhaustive log file or delete the cache for any of the Internet sites. When you add Varnish to your shared web hosting plan, you’ll be able to select the total amount of system memory that will be available to you for data caching purposes and how many sites will use Varnish. You can always order more memory in increments of 32 MB and, for top performance, you can set a dedicated IP address for the sites that will use Varnish. This will enable you to take full advantage of your websites and to have a lot of satisfied users.

Varnish in Semi-dedicated Servers

Varnish is included by default with all semi-dedicated servers that we are offering and you can use it for load balancing purposes. It’s available in your Hepsia hosting Control Panel. The Varnish content caching platform comes with 64 megabytes of system memory for cached data storing purposes and you can use it with any site that you host in your semi-dedicated account. In case you’re in need of more, you can increase the memory allocation. The memory itself is offered in increments of 32 MB in the Control Panel’s Upgrades section. The same section will permit you to add more instances as well, if you want to use the Varnish platform with multiple sites. The two upgrades can be added separately – you can cache the content of one single traffic-intensive site or run several sites with the default memory allowance. You can take full advantage of the Varnish caching platform in case you’ve got a dedicated IP address and you can order one with your semi-dedicated server package as well. The Hepsia Control Panel will grant you full control over the caching platform and, with no more than one click, you’ll be able to clear the cached files, to see a system log file or to reboot an instance.

Varnish in Dedicated Servers

All dedicated servers that are ordered with the custom-built Hepsia website hosting Control Panel feature Varnish, which is among the pre-installed platforms that you’ll get with the dedicated machine. The Varnish caching platform can be configured and managed without effort via Hepsia’s easy-to-work-with GUI and, with no more than one single click of the mouse, you can see an exhaustive log, add or reboot an instance, delete the cached data associated with any site and much more. Shortly after you configure Varnish for a particular domain or sub-domain, it will start caching the webpages requested by the visitors and as soon as it has cached enough content, you will observe a tremendously better site performance as well as a decreased load on the dedicated machine. With Varnish-dedicated memory starting at 3 gigabytes, you’ll be able to use the software platform for workload balancing purposes even if you run a large number of Internet sites on the dedicated machine.
