Varnish is a website accelerator platform, which caches info for quicker response times. It’s occasionally referred to as an HTTP reverse proxy as well and it interacts between a web server and an Internet browser. When a visitor accesses a specific web page, its content is requested by the browser, and then the server handles this request and delivers the requested content. If Varnish is enabled for a certain site, it will cache the pages at the first request and in case the user opens a cached page again, the data will be delivered by the accelerator platform instead of the server. The increased speed is an end result of the substantially faster response time that the Varnish platform offers as compared to any web server software. At the same time, this does not mean that the site visitors will keep seeing the exact same content over and over again, since any update on any of the web pages is reflected in the content that the Varnish platform keeps in its memory.

Varnish in Cloud Hosting

You can unleash Varnish’s potential and optimize your websites’ loading speed irrespective of the cloud hosting plan that you have picked and you can enable and configure the data caching platform with a couple of clicks using the intuitive graphical interface offered by our next-gen Hepsia hosting Control Panel. During the procedure, you will be able to select two separate things – how many websites will use the Varnish platform, i.e. the number of instances, and how much content will be cached, i.e. the amount of memory. The latter is offered in increments of 32 MB and is not linked to the number of instances, so you can use more instances and less memory and the other way around. In case you have lots of content on a particular site and you win numerous site visitors, more system memory will guarantee you better results. You may also consider employing a dedicated IP for the Internet sites that will use Varnish. Hepsia will offer you simple 1-click controls for turning off or restarting any instance, for erasing the cache associated with any Internet site and for seeing in-depth system logs.

Varnish in Semi-dedicated Servers

The Varnish platform is included in the standard service set that you will receive when you choose to host your websites under a semi-dedicated server account. You can activate it for any of your Internet sites via our next-generation Hepsia hosting Control Panel. The default memory that Varnish can use to cache content is 64 megabytes, but if you decide that you need more, you can upgrade this memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, i.e. the number of the sites that can use this platform at the same time. As these two things are not linked to each other, you can use several sites with the default memory or you can order more memory in increments of 32 megabytes and use all of it for one single site. The Varnish caching platform performs best when you get a dedicated IP address for the sites that utilize its power. The Hepsia Control Panel will offer you a simple way of rebooting any instance. Furthermore, you’ll be able to delete the cached data with just a click.

Varnish in VPS Servers

You can take full advantage of the load balancing capabilities of Varnish with any of our Linux VPS service when you choose Hepsia as your Control Panel. The Varnish data caching platform comes by default and the memory that it will be able to use to cache your site content depends upon the particular Virtual Private Server package that you’ve picked, but even with the lower-end packages, you will have no less than several hundred megabytes of system memory at your disposal solely for data caching purposes. This amount is sufficient to improve the work of multiple Internet sites. It’ll take a little time for you to notice the effects, as Varnish caches the content that site visitors open, but soon after that you’ll notice the considerably decreased load on the Virtual Private Server and the improved website browsing speed. The Varnish caching platform will allow you to use a lower-end Virtual Private Server plan for sites which would normally need a more costly hosting service.

Varnish in Dedicated Servers

If you order a dedicated server with the Hepsia Control Panel, you’ll get the Varnish caching platform at no extra fee and you will exert total control over it via a truly simple-to-use graphical interface – you will be able to start, to deactivate or to restart an instance, to browse an elaborate system log, to delete the cached content for any Internet site and much, much more. Varnish will have several GB of memory at its disposal, so even if you have resource-hungry sites with a large number of visitors, you will notice the much faster web page load speeds and the less load on the machine. This will become a fact shortly after you begin using Varnish, as it will require some time to cache the web pages that people access. You can take full advantage of the platform’s capacity in case the websites that are using it also use a dedicated IP, but considering the fact that your dedicated server includes a few IPs by default, you won’t need to pay anything on top of the monthly fee for the machine itself.
