Varnish is a web application accelerator tool, which has been gaining a lot in popularity in recent years, as it can increase the load speed of any website, at times even by 100%, based on the content. This tool is sometimes referred to as an HTTP reverse proxy too and is used to decrease the overall load on the server and to increase the access speed for the site visitors. Anytime a visitor opens a page on a specific site, the browser request is processed by the web server and the requested content is returned as a response. If the Varnish accelerator is activated, it caches the web pages that the visitor opens and in case any of them is accessed for a second time, it is served by Varnish and not by the server directly. The performance improvement comes from the fact that the accelerator handles the web requests significantly quicker than any web server, which leads to much faster browsing speeds for the visitors. In case any data is updated meanwhile, the cached web pages will also be updated the next time somebody attempts to open them.

Varnish in Website Hosting

Varnish comes as an optional upgrade with each Linux website hosting plan and if you would like to use it, you can add it to your website hosting account using the Upgrades menu in your Hepsia hosting Control Panel. There’re two separate features that can be upgraded – the instances and the system memory. The first one pertains to the number of the websites that you want to use Varnish for, whereas the second, which comes in increments of 32 megabytes, indicates the total amount of data that the data caching platform can cache at any particular time. Hepsia’s simple-to-work-with interface will permit you to cancel or to restart any instance, to see in-depth system logs or to erase the platform’s cache with just one click. For best results, you can employ a dedicated IP for the sites that will use the platform. With Varnish, your site will open substantially faster, which means more pleased users and prospective customers.

Varnish in Semi-dedicated Servers

The Linux semi-dedicated hosting plans that we offer will permit you to employ Varnish as soon as your brand-new semi-dedicated server account has been activated, since the content caching platform is offered by default. 64 MB of system memory will be assigned to Varnish the second your account is activated, so you can make use of this workload balancing software as soon as your website has been launched online. In case you’re in need of more system memory, you can get 32 megabytes at a time from the Hepsia hosting Control Panel’s Upgrades section and it will be assigned to your semi-dedicated server straight away. You can also increase the number of the Internet sites that employ Varnish, or the so-called ‘instances’, which are not directly linked to the amount of system memory that you use, which goes to say that you will have more versatility. The Varnish platform will seriously decrease the load on the semi-dedicated server that your websites generate, so your site visitors can enjoy fast-loading web pages. You will be able to manage the Varnish caching platform with ease via your Hepsia Control Panel using fast-access buttons. You’ll be able to start/cancel any of the instances that you’ve got, to clear the cache associated with any of your websites or to view system logs.

Varnish in Dedicated Servers

If you order a dedicated server with the Hepsia hosting Control Panel, you will get Varnish at no extra cost and you will exert total control over it through a really simple-to-use graphical interface – you will be able to start, to terminate or to reboot an instance, to see a comprehensive log, to clear the cached files associated with any site and much, much more. Varnish will have several GB of virtual memory at its disposal, so even if you host traffic-consuming websites with a large number of visitors, you’ll notice the considerably faster web page load times and the less load on your server. This will become a fact soon after you begin using the Varnish platform, as it will require some time to cache the content that visitors access. You can make the most of the platform’s capabilities if the sites that are using it use also a dedicated IP, but considering the fact that your dedicated server comes with a couple of IPs by default, you will not need to pay anything on top of your monthly fee for the machine itself.
