Varnish is a website accelerator, which has been gaining a lot of popularity lately, because it can increase the load speed of any Internet site, sometimes even by 100 percent, depending on the content itself. This tool is occasionally referred to as an HTTP reverse proxy too and is used to lower the overall load on the physical server and to accelerate the access speed for the site visitors. Every time a visitor accesses a page on a given website, the browser request is handled by the web server and the requested info is delivered as a reply. If the Varnish accelerator is enabled, it caches the web pages that the visitor opens and if any of them is accessed for a second time, it is served by Varnish and not by the web server directly. The boost in the performance comes from the fact that the accelerator processes the web requests considerably faster than any web server, which leads to much faster browsing speeds for the visitors. If any content is modified in the meantime, the cached pages will also be updated the next time somebody opens them.
Varnish in Website Hosting
In case you host your sites in a website hosting account with our company, you will be able to add Varnish with a couple of clicks of the mouse through your hosting Control Panel. The platform is offered as an optional upgrade with all our shared plans and you can choose the number of the sites that will use it and the maximum storage space that will be used for the cached content. The two upgradeable features in the Control Panel’s Upgrades section are the number of instances and the amount of memory and they are not directly tied to each other, so you can decide if you need a lot of memory for one single large-scale site or less memory for multiple smaller ones. You can use the full potential of the Varnish caching platform in case the sites use a dedicated IP address. With the hosting Control Panel, you can quickly start/reboot/remove an instance, clear the cached contents individually for each website that uses the Varnish platform or view an exhaustive log file.
Varnish in Semi-dedicated Servers
The semi-dedicated servers offered by us will permit you to use Varnish as soon as your brand-new account has been opened, as the data caching platform is offered by default. 64 megabytes of system memory will be allocated to Varnish the second your account is enabled, so you can make use of this load balancing software once your website has been published online. If you are in need of more system memory, you can get 32 MB at a time from the Upgrades section of the Hepsia Control Panel and it will be assigned to your semi-dedicated server straight away. You can also increase the number of the sites that employ Varnish, or the so-called ‘instances’, which are not bound directly to the amount of memory that you use, which means that you will enjoy more flexibility. The Varnish platform will seriously lower the load on the semi-dedicated server that your websites generate, so your website visitors can enjoy fast-loading web pages. You’ll be able to manage the Varnish caching platform without efforts via your Hepsia Control Panel using quick-access buttons. You’ll be able to start/terminate any of the instances that you have, to delete the cached files associated with any of your websites or to view system logs.
Varnish in VPS Servers
You can use Varnish with each of our VPS server packages at no extra cost, as the platform is pre-installed and is offered by default. The only requirement is that the server must be ordered with the Hepsia hosting Control Panel, through which you will be able to activate Varnish for any of your sites with just a few mouse clicks. Each VPS package comes with a different amount of system memory for content caching purposes, but you will get no less than several hundred MB, which is quite enough even for multiple regularly visited websites. Shortly after you activate Varnish, it’ll start caching the content that your website visitors open, so you will notice the substantially faster site load times and the reduced load on your Virtual Private Server in no time. The caching platform will allow you to use a less expensive server, as you won’t need that much power to guarantee the proper operation of your websites even if you’ve got high-demand sites with a lot of visitors. Optimal results are achieved if the Internet sites that use the Varnish platform also use a dedicated IP.
Varnish in Dedicated Servers
In case you order a dedicated server with the Hepsia Control Panel, you’ll get the Varnish content caching platform at no additional charge and you will have full control over it via a really time and effort saving graphical interface – you will be able to start, to disable or to restart an instance, to browse an in-depth system log, to clear the cache for any website and much, much more. The Varnish platform will have several GB of memory at its disposal, so even if you own resource-intensive websites with an immense number of visitors, you’ll notice the tremendously better site load speeds and the lowered load. This will happen shortly after you start using Varnish, since it will need some time to cache the site content that users request. You can take full advantage of the platform’s capabilities in case the Internet sites that are using it also use a dedicated IP address, but since your dedicated server includes a couple of IP addresses by default, you won’t need to pay anything on top of the monthly fee for the machine itself.
