Varnish is a web accelerator tool, which has been gaining a lot of popularity lately, because it can increase the load speed of any website, sometimes even by one hundred percent, based on the content itself. This tool is occasionally called an HTTP reverse proxy too and is used to reduce the overall load on the physical machine and to increase the browsing speed for the site visitors. Each time a visitor loads a page on a given site, the web browser request is processed 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 opened once more, it is delivered by Varnish and not by the web server directly. The performance improvement is due to the fact that the accelerator processes the browser requests substantially quicker than any web server, which leads to much faster browsing speeds for the visitors. In case any data is edited in the meantime, the cached pages will also be updated the next time someone tries to open them.
Varnish in Cloud Website Hosting
In case you host your websites in a cloud website hosting account with our company, you will be able to activate Varnish with a few mouse clicks through your hosting Control Panel. The content caching platform comes as an upgrade with all our shared web hosting packages and you can select the number of the sites that will use it and the total amount of system memory that will be available for the cached content. The two upgradeable features 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 choose whether you want plenty of memory for one large-size site or less memory for several smaller ones. You can unlock the full potential of Varnish in case the sites use a dedicated IP. Using the hosting Control Panel, you can quickly start/reboot/cancel an instance, delete the cached contents individually for each website which employs Varnish or check an elaborate system log file.
Varnish in Semi-dedicated Hosting
The Varnish data caching platform is an essential part of the standard set of services that you’ll get if you decide to host your Internet sites under a semi-dedicated server account. You can activate it for any of your websites via our advanced Hepsia Control Panel. The default system memory that the Varnish caching platform can use to cache data is 64 megabytes, but if you decide that you need more, you can upgrade this memory from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, in other words – the number of the sites that can use this platform at the same time. As these two things are not tied to each other, you can use a few Internet sites with the default memory or you can order more memory in increments of 32 megabytes and use all of it for one single web site. The Varnish caching platform works best if you assign a dedicated IP to the Internet sites that utilize its power. The Hepsia Control Panel will offer you an easy means of rebooting any instance. Furthermore, you will be able to clear the cached content with only one click.
Varnish in VPS
We offer Varnish with all of the Hepsia-managed VPS packages, so if you acquire a VPS with this hosting Control Panel, you will be able to make full use of the caching platform at no extra fee. Varnish can utilize different amounts of memory for caching purposes based on the very setup that you’ve picked during the VPS order process, but nevertheless, this amount will not be less than several hundred MB. This is more than enough to optimize the overall performance of a handful of busy Internet sites, so the faster site browsing speeds and the less load on your server will be discernible. The result may not be evident immediately, since the Varnish platform will need a certain amount of time to cache the website content that people browse, but soon after you set it up, you will perceive its full capacity. This platform will permit you to use a less powerful Virtual Private Server and to give less cash to get the exact same performance you’d get with a higher-end virtual machine without Varnish.
Varnish in Dedicated Hosting
In case you order a dedicated server with the Hepsia hosting Control Panel, you’ll get the Varnish caching platform at no extra cost and you’ll have complete control over it via an incredibly simple-to-navigate interface – you’ll be able to start, to remove or to restart an instance, to browse an exhaustive system log, to clear the cache for any website and much, much more. Varnish will have several gigabytes of memory at its disposal, so even if you host regularly visited sites with many visitors, you will notice the tremendously better website loading times and the lowered server load. This will happen soon after you start using the Varnish platform, since it will require some time to cache the website content that users browse. You can take full advantage of the platform’s potential if the websites that are using it use also a dedicated IP, but owing to the fact that your server comes with a few IPs by default, you will not need to pay anything on top of your monthly fee for the server itself.
