Varnish is a web accelerator, which has been gaining a lot of popularity in recent years, as it can increase the loading speed of any site, at times 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 server load and to improve the browsing speed for the site visitors. Each time a visitor opens a page on a particular Internet site, the web browser request is handled by the web server and the requested info is returned as a response. If Varnish is enabled, it caches the pages that the website visitor opens and if any of them is opened once again, it is fetched by Varnish and not by the server directly. The improvement in the performance comes from 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. In case any content is updated in the meantime, the cached pages will also be ‘refreshed’ the next time someone opens them.

Varnish in Cloud Hosting

You can unlock Varnish’s potential and improve your websites’ loading speed regardless of the cloud hosting package that you have selected and you can enable and set up the data caching platform with a few clicks of the mouse from the easy-to-work-with interface offered by our cutting-edge Hepsia hosting Control Panel. In the meantime, you will be able to choose two different things – how many websites will employ the Varnish caching platform, i.e. the number of instances, and how much information will be cached, in other words – the amount of system memory. The latter is available in increments of 32 megabytes and is not linked to the number of instances, so you can add more instances and less memory and vice versa. If you have a lot of content on a specific site and you draw numerous site visitors, more system memory will guarantee you a better result. You may also consider using a dedicated IP for the websites that will use Varnish. Hepsia will offer you easy 1-click controls for stopping or rebooting any instance, for erasing the cache associated with any Internet site and for seeing in-depth logs.

Varnish in Semi-dedicated Servers

The Varnish caching platform is part of the standard service set that you’ll receive if you decide to host your sites under a semi-dedicated server account. You can enable it for any of your Internet sites through our advanced Hepsia hosting Control Panel. The default amount of system memory that the Varnish platform can use to cache data is 64 MB, but if you decide that you want more, you can upgrade this amount from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, i.e. the number of the Internet sites that can use this platform simultaneously. Since these two features aren’t tied to each other, you can use a few websites with the default amount of memory or you can add more memory in increments of 32 MB and use all of it for a single site. The Varnish caching platform works best if you allocate a dedicated IP address to the sites that utilize its power. Hepsia will provide you with a simple means of restarting any instance. In addition, you’ll be able to delete the cached contents with only one single click of the mouse.

Varnish in VPS Servers

The Varnish data caching platform comes by default with all Linux VPS servers that we offer given that the VPS is ordered with the Hepsia hosting Control Panel, so you can improve the overall performance of your sites with just a few mouse clicks. The more powerful the plan, the more system memory will be available to Varnish, but even with a less powerful package, the caching platform will be able to utilize several hundred megabytes, so even if you have a handful of sites, you’ll notice a significant reduction in the overall server load and a substantially faster site load speed. The platform will have to work for a little while as the visitors navigate the site and as soon as the content has been cached, you’ll distinguish the effects. One of the pluses of employing Varnish is that a lower-end and less pricey Virtual Private Server package will accomplish the same job as a more pricey one without the platform, so not only will your Internet sites perform considerably better, but you’ll also spare some money.

Varnish in Dedicated Servers

If you order a dedicated server with the Hepsia Control Panel, you will acquire the Varnish platform at no extra cost and you will have complete control over it via a really time and effort saving graphical interface – you will be able to start, to delete or to reboot an instance, to check an exhaustive log, to clear the cache for any Internet site and much, much more. Varnish will have several gigabytes of virtual memory at its disposal, so even if you have traffic-intensive websites with multiple visitors, you’ll notice the much better website loading times and the decreased load on your dedicated machine. This will happen shortly after you start using the Varnish platform, since it will require a certain amount of time to cache the content that visitors open. You can make the most of the platform’s potential if the Internet sites that are using it also use a dedicated IP, but owing to the fact that your dedicated server comes with several IP addresses by default, you will not have to pay anything on top of the monthly charge for the server itself.
