Varnish is a web application accelerator, which has been gaining a lot in popularity lately, because it can increase the loading speed of any website, sometimes even by 100%, based on the content. This tool is occasionally referred to as an HTTP reverse proxy too and is used to lower the overall load on the physical machine and to improve the browsing 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 info is sent as a reply. If the Varnish accelerator is activated, it caches the pages that the visitor opens and if any of them is accessed again, it is fetched by Varnish and not by the server directly. The boost in the performance is due to the fact that the accelerator handles the browser requests significantly faster than any web server, which results in much faster browsing speeds for the website visitors. If any data is updated meanwhile, the cached web pages will also be ‘refreshed’ the next time someone tries to open them.

Varnish in Hosting

Varnish is available as an optional upgrade with all our Linux hosting services. You can add it to your hosting account through the Hepsia hosting Control Panel, which comes with all shared packages and you’ll get a rather easy-to-work-with graphical interface, which will grant you complete control over the caching platform. Using 1-click quick-access controls, you can restart or deactivate any of the instances, in other words – Varnish will no longer be activated for a certain site. You can also view a detailed log or erase the cache associated with any of the Internet sites. When you add Varnish to your shared hosting package, you will be able to select the maximum amount of system memory that will be at your disposal for data caching purposes and the number of the websites that will use Varnish. You can always add more memory in increments of 32 MB and, for best performance, you can get a dedicated IP for the sites that will use Varnish. This will enable you to get the most out of your Internet sites and to have many satisfied site users.

Varnish in Semi-dedicated Hosting

Varnish comes by default with all semi-dedicated hosting that we offer and you can use it for load balancing purposes. It is available in your Hepsia hosting Control Panel. The content caching platform comes with 64 MB of system memory for cached data storing purposes and you can use it with any site that you host in your account. If you need more, you can increase the memory allowance. The memory itself is offered in increments of 32 megabytes in the Upgrades section of the Control Panel. The very same section will allow you to create more instances too, if you’d like to use the Varnish caching platform with multiple websites. The two upgrades can be ordered separately – you can cache the content of a single resource-heavy Internet site or run several websites with the default memory allowance. You can take full advantage of the Varnish caching platform if you have a dedicated IP address and you can get one with your semi-dedicated package as well. The Hepsia Control Panel will grant you total control over the platform and, with no more than one single mouse click, you’ll be able to delete the cached contents, to check a log or to reboot an instance.

Varnish in VPS Web Hosting

The Varnish content caching platform comes by default with each of the Linux VPS web hosting that we offer on the condition that the machine is ordered with the Hepsia Control Panel, so you can boost the overall performance of your websites with just a few clicks. The more powerful the package, the more memory Varnish will have at its disposal, but even with a lower-end package, the caching platform will be able to utilize several hundred megabytes, so even if you manage a handful of Internet sites, you will notice a noticeable reduction in the overall server load and a much better web page load speed. The Varnish platform will have to work for a little while while the visitors browse the pages and once the site content has been cached, you will see the effect. One of the benefits of using Varnish is that a lower-end and less expensive Virtual Private Server plan will accomplish the same job as a more costly one without the platform, so not only will your sites work significantly better, but you will also spare a certain amount of money.

Varnish in Dedicated Servers Hosting

In case you order a dedicated server with the Hepsia Control Panel, you’ll get the Varnish caching platform at no additional fee and you’ll exert total control over it via a quite simple-to-use interface – you’ll be able to start, to delete or to restart an instance, to view an in-depth log, to clear the cache for any site and much, much more. Varnish will have several gigabytes of system memory at its disposal, so even if you run popular Internet sites with an immense number of visitors, you will notice the significantly faster site load times and the less load on your dedicated machine. This will become a fact shortly after you start using Varnish, since it will require a certain amount of time to cache the pages that people browse. You can get the most out of the platform’s potential if the sites that are using it use also a dedicated IP, but due to the fact that your dedicated server comes with a couple of IP addresses by default, you will not have to pay anything on top of your monthly charge for the machine itself.
