Varnish is a web app accelerator platform, which caches data for faster access. It is occasionally called an HTTP reverse proxy too and it works between a web server and a browser. When a site visitor opens a specific page, its content is requested by the browser, and then the web server handles this browser request and sends back the requested information. If Varnish is enabled for a given website, it will cache the pages on the first visit and if the visitor visits a cached page once again, the content will be delivered by the accelerator platform instead of the server. The boosted speed is a result of the substantially faster response speed that Varnish offers compared with any server software. Of course, this doesn’t mean that the users will continue being served the same content over and over again, since any change on any of the pages is reflected in the content that Varnish keeps in its system memory.
Varnish in Hosting
In case you host your websites in a hosting account with our company, you will be able to add Varnish with several clicks of the mouse from your hosting Control Panel. The platform is available as an optional upgrade with all our shared hosting plans and you can choose the number of the sites that will use it and the total storage space that will be used for the cached content. The two features that can be upgraded in the Control Panel’s Upgrades section are the number of instances and the amount of memory and they aren’t tied directly to each other, so you can decide whether you need plenty of memory for a single large-size site or less memory for multiple smaller ones. You can make use of the full potential of Varnish if the websites use a dedicated IP. Using the Control Panel, you can quickly start/reboot/disable an instance, delete the cached data individually for each site that uses the Varnish platform or see an exhaustive system log.
Varnish in Semi-dedicated Servers
All our semi-dedicated service include Varnish by default, so you can make use of the web application accelerator and optimize the speed of any website that you host on our platform. You’ll get 64 megabytes of system memory particularly for Varnish at no additional charge and you will be able to create an instance with no more than a couple of mouse clicks from the Hepsia hosting Control Panel, which is included with the semi-dedicated server packages. In case you want more memory, the latter is offered in increments of 32 megabytes through the Control Panel’s Upgrades section and it will be available to you right away. You can also add more instances as a separate upgrade, so you can choose if plenty of content will be cached for a single site or whether the available memory will be utilized by multiple sites. Hepsia will permit you to reboot or to cancel any instance, to see the system log associated with it or to delete the cached data using one-click controls. To get the most out of Varnish, you can set a dedicated IP for the sites that will use it.
Varnish in VPS Servers
You can take full advantage of the workload balancing capabilities of Varnish with each of our VPS service in case you pick Hepsia as your Control Panel. The content caching platform comes by default and the system memory that it’ll be able to utilize to cache the content of your sites is dependent on the given VPS package that you have chosen, but even with the less powerful plans, you will have no less than several hundred MB of memory at your disposal exclusively for caching purposes. This amount is enough to enhance the performance of multiple Internet sites. It’ll take a little time for you to distinguish the effects, since the Varnish platform caches the content that visitors browse, but shortly after that you’ll notice the considerably lowered load on the VPS server and the enhanced site browsing speed. The Varnish platform will permit you to use a lower-end VPS package for sites which would usually need a more high-priced hosting solution.
Varnish in Dedicated Servers
If you need the most powerful website hosting solution and you get one of the Linux dedicated service that we offer, you will be able to use the Varnish platform to improve the performance of your Internet sites at no additional fee as long as the server is ordered with our advanced Hepsia hosting Control Panel. Its simple-to-navigate GUI will enable you to keep an eye on system processes, to clear the cached files or to reboot any instance with one single click of the mouse. The minimum amount of system memory that Varnish can use to cache content is three gigabytes, which is more than enough for an enormous number of resource-hungry Internet sites, so your dedicated server will be able to cope with a substantial load while your visitors are enjoying a seamless browsing experience. Since your server will include several different dedicated IPs, you will be able to make use of Varnish’s maximum capacity.
