Varnish is a data caching platform, which is sometimes referred to as an HTTP reverse proxy. It is a website accelerator tool that can increase the loading speed of a site by up to one thousand percent, depending on its content. Every time a visitor opens any page on a site that uses Varnish, the platform caches the page and delivers it instead of the web server if the visitor opens it again. Thus, the web browser request from the visitor is not processed by the web server and the page will open much faster, as Varnish can serve content many times faster than any server software. The result is a substantially faster loading website, which leads to an immensely improved website browsing experience. In case any of the cached pages is updated on the actual website, the content that Varnish caches in its memory is ‘refreshed’ too, so the users will never see out-of-date data.
Varnish in Shared Hosting
In case you host your sites in a shared hosting account with us, you will be able to add Varnish with several mouse clicks via your hosting Control Panel. The content caching platform comes as an optional upgrade with all our web hosting plans and you can select how many websites will use it and the maximum storage space that will be used for the cached data. The two features that can be upgraded in the Control Panel’s Upgrades section are the amount of memory and the number of instances and they aren’t linked directly to each other, so you can choose whether you want a lot of memory for a single large-scale site or less memory for several smaller ones. You can use the full potential of the Varnish caching platform if the websites use a dedicated IP address. With the Control Panel, you can easily start/reboot/terminate an instance, delete the cached files individually for each website that employs the Varnish platform or view an elaborate log file.
Varnish in Semi-dedicated Servers
The semi-dedicated servers that we’re offering will allow you to use Varnish as soon as your new semi-dedicated account has been activated, since the platform is available by default. 64 megabytes of system memory will be assigned to Varnish the second your account is activated, so you can make use of this load balancing software as soon as your website has been taken online. If you need more system memory, you can add 32 MB at a time from the Hepsia hosting Control Panel’s Upgrades section and it will be assigned to your semi-dedicated machine right away. You can also increase the number of the sites that employ Varnish, or the so-called ‘instances’, which are not directly bound to the amount of system memory that you use, which suggests that you’ll have more freedom. The Varnish platform will significantly reduce the load on the machine that your sites generate, so your website visitors can enjoy fast-opening pages. You will be able to manage Varnish without any effort from your Control Panel using quick-access controls. You will be able to start/disable any of the instances that you’ve got, to clear the cached content for any of your Internet sites or to view system log files.
Varnish in VPS Servers
The Varnish platform is included by default with each of the VPS servers offered by our company on the condition that the virtual server is ordered with the Hepsia Control Panel, so you can boost the work of your sites with only a few mouse clicks. The more powerful the package, the more system memory Varnish will have at its disposal, but even with a less powerful package, the caching platform will be able to utilize several hundred megabytes, so even if you have several different sites, you’ll notice a noticeable reduction in the server load and a tremendously faster page loading speed. The Varnish caching platform will need to work for a while while the visitors navigate the pages and once the site content has been cached, you will perceive the results. One of the benefits of employing Varnish is that a lower-end and less expensive package will accomplish the very same job as a more high-priced one without the caching platform, so not only will your sites work much better, but you’ll also spare some money.
Varnish in Dedicated Servers
In case you order a dedicated server with the Hepsia Control Panel, you will get the Varnish caching platform at no extra charge and you will have full control over it through an amazingly simple-to-work-with graphical interface – you’ll be able to start, to cancel or to reboot an instance, to see an in-depth system log, to clear the cached data associated with any Internet site and much, much more. Varnish will have several gigabytes of system memory at its disposal, so even if you have large websites with an enormous number of visitors, you will notice the substantially faster web page loading times and the decreased load on the server. This will happen shortly after you start using the Varnish platform, since it will require a certain amount of time to cache the web pages that visitors browse. You can take full advantage of the platform’s capabilities in case the websites that are using it also use a dedicated IP, but considering the fact that your server comes with a few IP addresses by default, you will not have to pay anything on top of your monthly fee for the machine itself.
