Varnish is a web application accelerator tool, which has been gaining a lot of popularity lately, as it can increase the load speed of any Internet site, sometimes even by 100%, based on the content. This tool is occasionally called an HTTP reverse proxy as well and is used to reduce the overall load on the physical machine and to increase the browsing speed for the site visitors. Every time a visitor loads a page on a certain Internet site, the web browser request is processed by the web server and the requested content is served as a response. If the Varnish accelerator is enabled, it caches the web pages that the site visitor browses and if any of them is loaded again, it is served by Varnish and not by the server directly. The improvement in the performance comes from the fact that the accelerator handles the web requests substantially faster than any web server, which leads to much faster browsing speeds for the website visitors. In case any content is modified in the meantime, the cached pages will also be updated the next time somebody opens them.

Varnish in Shared Hosting

You can take advantage of Varnish’s potential and increase your websites’ load speed irrespective of the shared hosting package that you have chosen and you can add and configure the content caching platform with several clicks of the mouse via the user-friendly interface offered by our leading-edge Hepsia Control Panel. In the meantime, you’ll be able to choose two separate things – how many sites will use the Varnish caching platform, i.e. 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 linked to the number of instances, so you can use more instances with less memory and vice versa. If you have a lot of content on a particular site and you win lots of site visitors, more system memory will give you better results. You may also consider using a dedicated IP address for the Internet sites that will use Varnish. Hepsia will provide you with simple 1-click buttons for discontinuing or rebooting any instance, for deleting the cache associated with each Internet site and for seeing exhaustive logs.

Varnish in Semi-dedicated Servers

The semi-dedicated plans that we offer will allow you to use Varnish as soon as your brand-new semi-dedicated server account has been created, since the caching platform is available by default. 64 megabytes of system memory will be allocated to Varnish the moment your account is activated, so you can take advantage of this load distribution software once your website has been built. In case you need more system memory, you can order 32 MB at a time from the Upgrades section of the Hepsia hosting Control Panel and it will be assigned to your semi-dedicated server straight away. You can also increase the number of the websites that use Varnish, or the so-called ‘instances’, which are not bound directly to the amount of system memory that you use, which goes to say that you’ll enjoy more flexibility. The Varnish caching platform will noticeably lower the load on the machine that your websites produce, so your site visitors can enjoy fast-loading web pages. You’ll be able to manage Varnish with no effort from your Hepsia Control Panel using fast-access controls. You will be able to start/terminate any of the instances that you have, to clear the cached files for any of your Internet sites or to see system log files.

Varnish in Dedicated Servers

All dedicated web hosting plans which are ordered with the in-house developed Hepsia hosting Control Panel feature Varnish, which is one of the pre-installed platforms that you’ll get with the dedicated machine. The Varnish caching platform can be activated and managed without efforts from Hepsia’s simple-to-use interface and, with no more than one single click of the mouse, you can see an in-depth system log, add or reboot an instance, clear the cached files associated with any website and much, much more. Soon after you enable the Varnish platform for a specific domain or subdomain, it will begin caching the web pages opened by your website visitors and once it has cached enough web content, you’ll witness a substantially faster website performance in addition to a decreased load on the server. With Varnish-dedicated virtual memory starting at 3 gigabytes, you’ll be able to use the software platform for workload balancing purposes even if you run lots of websites on your dedicated machine.
