Varnish is a web accelerator tool, which has been gaining a lot in popularity in recent years, because it can increase the load speed of any site, sometimes even by one hundred percent, based on the content itself. This tool is sometimes referred to as a caching HTTP reverse proxy as well and is used to decrease the overall load on the physical server and to improve the access speed for the site visitors. Every time a visitor opens a page on a certain Internet site, the web browser request is handled by the web server and the requested data is served as a reply. If Varnish is activated, it caches the web pages that the website visitor opens and in case any of them is accessed for a second time, it is served by Varnish and not by the web server directly. The increase in the overall performance comes from the fact that the accelerator processes the web requests substantially faster than any web server, which leads to much faster browsing speeds for the users. If any data is modified meanwhile, the cached pages will also be ‘refreshed’ the next time somebody opens them.

Varnish in Shared Web Hosting

Varnish is offered as an optional upgrade with all our shared web hosting service. You can add it to your web hosting account through the Hepsia hosting Control Panel, which is offered with all shared hosting packages and you’ll get a very user-friendly graphical interface, which will grant you full control over the caching system. Using 1-click quick-access controls, you can reboot or turn off any of the instances, in other words – Varnish will no longer work for a particular site. You can also check a detailed system log or erase the cache for any of the Internet sites. When you add Varnish to your web hosting package, you will be able to select the total amount of 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 megabytes and, for maximum performance, you can set a dedicated IP address for the websites that will use Varnish. This will allow you to take full advantage of your Internet sites and to have many happy users.

Varnish in Semi-dedicated Servers

The semi-dedicated service that we offer will permit you to employ Varnish once your brand new account has been created, since the content caching platform is offered by default. 64 MB of system memory will be allocated to Varnish the second your account is activated, so you can take advantage of this load distribution software once your website has been published to the web. If you are in need of more memory, you can add 32 MB at a time from the Upgrades section of the Hepsia Control Panel and it will be assigned to your semi-dedicated server straight away. You can also increase the number of the sites that employ Varnish, or the so-called ‘instances’, which are not linked directly to the amount of memory that you use, which means that you’ll enjoy more freedom. The Varnish platform will considerably decrease the load on the server that your websites cause, so your site visitors can enjoy fast-opening web pages. You will be able to manage the Varnish platform effortlessly through your Hepsia Control Panel using quick-access controls. You’ll be able to start/discontinue any of the instances that you have, to clear the cached content for any of your websites or to check system logs.

Varnish in VPS Servers

You can take full advantage of the load balancing capabilities of Varnish with all our Linux VPS servers if you choose Hepsia as your web hosting Control Panel. The Varnish content caching platform is offered by default and the system memory that it’ll be able to use to cache the content of your websites is dependent on the specific package that you’ve selected, but even with the less powerful plans, you’ll have at least several hundred MB of system memory at your disposal solely for content caching purposes. This amount is enough to enhance the work of numerous websites. It will take a little time for you to observe the results, as Varnish caches the content that site visitors browse, but after that you will notice the considerably decreased load on your virtual machine and the increased site load speed. Varnish will allow you to use a less powerful VPS plan for Internet sites which would normally require a more high-priced hosting solution.

Varnish in Dedicated Servers

All dedicated service which are ordered with the in-house developed Hepsia website hosting Control Panel include Varnish, which is one of the pre-installed software platforms that you will get with the dedicated server. The Varnish caching platform can be set up and managed without any effort from Hepsia’s intuitive graphical interface and, with no more than a click, you can browse a detailed system log, add or reboot an instance, clear the cached data associated with any Internet site and much more. Soon after you activate the Varnish platform for a particular domain or sub-domain, it will begin caching the web pages browsed by the site visitors and once it has cached enough web content, you will observe a significantly faster website performance in addition to a lowered load on the machine. With Varnish-dedicated virtual memory starting at three gigabytes, you will be able to use the platform for workload balancing purposes even if you run many sites on the machine.
