Varnish is a website accelerator platform, which caches data for faster access. It’s occasionally called a caching HTTP reverse proxy too and it works between a web server and a browser. When a site visitor accesses a certain web page, its content is requested by the web browser, and then the web server processes this browser request and sends back the required info. If Varnish is activated for a certain site, it will cache its pages on the very first request and if the user accesses a cached page for a second time, the content will be delivered by the caching platform instead of the web server. The improved speed is a result of the substantially faster response time that Varnish offers as compared with any web server software. At the same time, this doesn’t mean that the website visitors will continue seeing the same content again and again, because any update on any of the web pages is reflected in the content that the Varnish platform stores in its memory.
Varnish in Web Hosting
If you host your Internet sites under a web hosting account with us, you’ll be able to activate Varnish with a few clicks of the mouse through your hosting Control Panel. The platform is offered as an upgrade with all our hosting packages and you can choose the number of the websites that will use it and the total amount of system memory that will be used for the cached data. The two features that can be upgraded in the Upgrades section of the Control Panel are the number of instances and the amount of system memory and they’re not linked directly to each other, so you can decide whether you want lots of memory for one large-size website or less memory for several smaller ones. You can unlock the full potential of the Varnish platform in case the websites use a dedicated IP address. With the hosting Control Panel, you can effortlessly start/reboot/cancel an instance, delete the cached content independently for each site that uses Varnish or see an in-depth system log file.
Varnish in Semi-dedicated Servers
All our semi-dedicated servers include Varnish by default, so you can make full use of the web application accelerator tool and increase the speed of any website that you host on our semi-dedicated servers. You will get 64 MB of memory exclusively for the Varnish accelerator at no additional fee and you’ll be able to enable an instance with no more than a couple of clicks via the Hepsia hosting Control Panel, which is included with the semi-dedicated packages. If you need more memory, the latter is offered in increments of 32 MB through the Control Panel’s Upgrades section and it will be available to you instantaneously. You can also order more instances as a separate upgrade, so you can decide if lots of content will be cached for a single website or if the memory will be used by multiple sites. Hepsia will permit you to reboot or to stop any instance, to check the system log file for it or to delete the cached files using 1-click controls. To get the most out of Varnish, you can allocate a dedicated IP to the sites which will use it.
Varnish in VPS Servers
The Varnish content caching platform is included by default with all Linux VPS web hosting service that we’re offering given that the VPS server is ordered with the Hepsia hosting Control Panel, so you can enhance the work of your websites with just a couple of clicks of the mouse. The more powerful the plan, the more system memory Varnish will have at its disposal, but even with a less powerful plan, the caching platform will be able to utilize several hundred megabytes, so even if you have several websites, you will notice a noticeable decrease in the server load and a much faster site load speed. The platform will need to work for a little while as the users navigate the site and once the content has been cached, you’ll distinguish the results. One of the upsides of employing Varnish is that a less powerful and less high-priced Virtual Private Server package will accomplish the exact same job as a more costly one without the platform, so not only will your sites work substantially better, but you’ll also save some cash.
Varnish in Dedicated Servers
If you order a dedicated server with the Hepsia Control Panel, you will get Varnish at no extra charge and you’ll exert complete control over it via a pretty easy-to-work-with interface – you’ll be able to start, to stop or to restart an instance, to check an elaborate log, to delete the cached files for any Internet site and much more. Varnish will have several gigabytes of virtual memory at its disposal, so even if you’ve got traffic-heavy sites with an enormous number of visitors, you will notice the much better website load speeds and the decreased load on the server. This will happen shortly after you begin using Varnish, as it will need some time to cache the content that people browse. You can take full advantage of the platform’s potential if the Internet sites that are using it use also a dedicated IP address, but considering the fact that your server comes with a few IPs by default, you will not have to pay anything on top of your monthly fee for the machine itself.
