Varnish is a web app accelerator platform, which caches information for the sake of quicker response times. It is occasionally referred to as an HTTP reverse proxy too and it works between a web server and a browser. When a site visitor accesses a specific webpage, its content is requested by the web browser, and then the web server processes this request and sends back the requested data. If Varnish is enabled for a specific website, it will cache its pages on the very first visit and if the user opens a cached page again, the info will be delivered by the accelerator platform and not by the web server. The boosted load speed is a result of the considerably faster response speed that Varnish offers compared to any server software. Of course, this does not mean that the users will keep being served the same content again and again, because any modification on any of the pages is reflected in the content that the Varnish platform stores in its system memory.

Varnish in Web Hosting

Varnish comes as an optional upgrade with each and every Linux web hosting service and if you want to use it, you can add it to your shared website hosting account via the Upgrades section in your Hepsia hosting Control Panel. There are two different features that can be upgraded – the number of instances and the memory. The first one refers to the number of the sites that you would like to employ Varnish for and the second one, which is offered in increments of 32 megabytes, indicates the maximum amount of content that the content caching platform can store at any given time. The Hepsia Control Panel’s simple-to-use interface will allow you to stop or to reboot any instance, to view detailed system logs or to get rid of the platform’s cache with just one mouse click. For best results, you can employ a dedicated IP address for the Internet sites that will use the platform. With Varnish, your Internet site will load tremendously faster, meaning more pleased visitors and potential clients.

Varnish in Semi-dedicated Servers

Varnish is an essential part of the standard set of services that you’ll receive when you choose to host your websites in a semi-dedicated server account. You can activate it for any of your websites via our leading-edge Hepsia Control Panel. The default memory that the Varnish platform can use to cache content is 64 MB, but if you decide that you want 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 Internet sites that can use this platform simultaneously. Since these two features are not tied to each other, you can use several Internet sites with the default amount of memory or you can add more memory in increments of 32 MB and use all of it for one single site. The Varnish platform performs best when you allocate a dedicated IP address to the websites that utilize its power. The Hepsia Control Panel will offer you a simple way of restarting any instance. What’s more, you will be able to clear the cached contents with only a click.

Varnish in VPS Servers

You can use the workload balancing capabilities of Varnish with each of our VPS servers in case you choose Hepsia as your Control Panel. The Varnish caching platform is offered by default and the memory that it will be able to use to cache the content of your websites is dependent on the given Virtual Private Server plan that you’ve picked, but even with the less powerful plans, you will have no less than several hundred megabytes of system memory at your disposal exclusively for caching purposes. This amount is enough to enhance the performance of numerous Internet sites. It’ll take a little time for you to see the results, as Varnish caches the content that site visitors browse, but shortly thereafter you’ll notice the significantly decreased load on your VPS and the improved site browsing speed. The Varnish platform will allow you to make use of a lower-end Virtual Private Server plan for sites which would usually need a more costly hosting service.

Varnish in Dedicated Servers

In case you order a dedicated server with the Hepsia Control Panel, you will obtain the Varnish content caching platform at no extra charge and you’ll have full control over it via a rather easy-to-work-with graphical interface – you’ll be able to start, to stop or to restart an instance, to browse a detailed system log, to clear the cached content associated with any site and much, much more. The Varnish platform will have several GB of virtual memory at its disposal, so even if you manage traffic-hungry sites with a large number of visitors, you will notice the considerably faster page load speeds and the reduced load on your dedicated server. This will happen soon after you begin using the Varnish platform, since it will require some time to cache the site content that people request. You can make the most of the platform’s capability if the websites that are using it use also a dedicated IP, but due to the fact that your server includes a few IPs by default, you won’t need to pay anything on top of your monthly fee for the machine itself.
