Varnish is a website accelerator tool, which has been gaining a lot of popularity in recent years, as it can increase the loading speed of any site, sometimes even by 100%, depending on the content itself. This tool is sometimes called a caching HTTP reverse proxy as well and is used to lower the overall load on the physical server and to enhance the browsing speed for the site visitors. Whenever a visitor accesses a page on a particular Internet site, the web browser request is taken care of by the web server and the requested data is returned as a response. If the Varnish accelerator is enabled, it caches the pages that the website visitor browses and if any of them is opened once more, it is served by Varnish and not by the web server directly. The performance improvement is due to the fact that the accelerator handles the browser requests substantially faster than any web server, which leads to much faster browsing speeds for the site visitors. If any data is updated in the meantime, the cached webpages will also be updated the next time somebody tries to open them.

Varnish in Cloud Hosting

Varnish comes as an optional upgrade with all our Linux cloud hosting. You can add it to your hosting account via the Hepsia hosting Control Panel, which comes with all shared plans and you will get a rather simple-to-use interface, which will give you full control over the caching system. Using 1-click quick-access buttons, you can restart or stop any of the instances, i.e. Varnish will no longer be enabled for a given Internet site. You can also see a comprehensive log or clear the cache for any of the Internet sites. When you add Varnish to your hosting package, you’ll be able to select the total amount of memory that will be at your disposal for data caching purposes and how many websites will use Varnish. You can always order more memory in increments of 32 MB and, for optimum performance, you can assign a dedicated IP address to the websites that will use Varnish. This will permit you to get the most out of your Internet sites and to have a lot of pleased website users.

Varnish in Semi-dedicated Servers

The Linux semi-dedicated servers that we’re offering will permit you to employ Varnish as soon as your new semi-dedicated server account has been opened, as the platform is available by default. 64 MB of system memory will be assigned to Varnish the second your account is enabled, so you can use this load distribution software once your website has been published online. In case you’re in need of more memory, you can get 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 momentarily. You can also increase the number of the websites that use Varnish, or the so-called ‘instances’, which are not directly tied to the amount of memory that you use, which suggests that you’ll have more versatility. The platform will immensely decrease the load on the semi-dedicated server that your sites produce, so your site visitors can enjoy fast-loading web pages. You will be able to manage the Varnish platform without effort via your Hepsia Control Panel using quick-access controls. You will be able to start/disable any of the instances that you’ve got, to clear the cached content for any of your sites or to view system logs.

Varnish in VPS Servers

You can use Varnish with any of our VPS server packages at no extra fee, as the caching platform is pre-installed and is included by default. The one and only precondition is that the Virtual Private Server must be ordered with the Hepsia Control Panel, through which you’ll be able to activate Varnish for any of your sites with just a few mouse clicks. Each Virtual Private Server package features a different amount of memory for content caching purposes, but you will get no less than several hundred MB, which is quite sufficient even for several regularly visited sites. Shortly after you set up the Varnish platform, it’ll start caching the content that your site visitors access, so you’ll notice the substantially faster web page load speeds and the reduced load on your VPS server very soon. The Varnish caching platform will allow you to use a less costly server, since you will not require that much power to warrant the proper operation of your sites even if you have high-demand websites with a lot of visitors. Maximum results are accomplished if the websites which use the Varnish caching platform also use a dedicated IP.

Varnish in Dedicated Servers

If you order a dedicated server with the Hepsia Control Panel, you will obtain the Varnish content caching platform at no additional charge and you’ll exert full control over it via a rather simple-to-use interface – you will be able to start, to cancel or to reboot an instance, to view an exhaustive log, to delete the cached data associated with any Internet site and much, much more. The Varnish caching platform will have several gigabytes of virtual memory at its disposal, so even if you manage busy sites with many visitors, you will notice the considerably faster page loading speeds and the decreased load on the dedicated server. This will happen shortly after you begin using the Varnish platform, since it will need a certain amount of time to cache the pages that users open. You can get the most out of the platform’s potential if the sites that are using it also use a dedicated IP address, but considering the fact that your server includes several IP addresses by default, you will not have to pay anything on top of your monthly charge for the server itself.
