Varnish is a web accelerator tool, which has been gaining a lot in popularity lately, as it can increase the load speed of any website, sometimes even by 100 percent, based on the content itself. This tool is occasionally called a caching HTTP reverse proxy too and is used to lower the overall load on the physical machine and to improve the access speed for the site visitors. Whenever a visitor loads a page on a given site, the browser request is taken care of by the web server and the requested info is sent as a response. If Varnish is enabled, it caches the pages that the website visitor browses and in case any of them is accessed once more, it is served by Varnish and not by the server directly. The increase in the performance is due to the fact that the accelerator handles the web requests significantly faster than any web server, which leads to much faster browsing speeds for the website visitors. In case any content is edited in the meantime, the cached pages will also be ‘refreshed’ the next time somebody attempts to access them.
Varnish in Website Hosting
Varnish is offered as an optional upgrade with all our Linux website hosting plans. You can add it to your hosting account via the Hepsia Control Panel, which is offered with all shared hosting packages and you’ll get an exceptionally simple-to-use interface, which will give you complete control over the data caching platform. Using 1-click fast-access buttons, you can reboot or stop any of the instances, in other words – Varnish will no longer be enabled for a particular Internet site. You can also see an elaborate log file or clear the cache associated with any of the Internet sites. When you add Varnish to your shared web hosting package, you’ll be able to select the total amount of memory that will be at your disposal for content caching purposes and the number of the sites that will use Varnish. You can always add more memory in increments of 32 MB and, for optimal performance, you can allocate a dedicated IP to the sites that will use Varnish. This will permit you to get the most out of your sites and to have a lot of gratified site users.
Varnish in Semi-dedicated Servers
The Varnish platform is an essential part of the standard service set that you will acquire in case you decide to host your Internet sites under a semi-dedicated server account. You can activate it for any of your websites via our leading-edge Hepsia Control Panel. The default amount of memory that Varnish can use to cache data is 64 megabytes, but in case you decide that you want more, you can upgrade this amount of 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 caching platform simultaneously. Since these two things aren’t linked to each other, you can use a few instances with the default memory or you can add more memory in increments of 32 megabytes and use all of it for a single Internet site. The Varnish platform works best if you use a dedicated IP for the sites that utilize its power. Hepsia will offer you a simple means of rebooting any instance. Furthermore, you will be able to delete the cached files with just one click.
Varnish in VPS Servers
You can take advantage of Varnish with all our VPS server plans at no extra charge, as the content caching platform is pre-installed and is offered by default. The one and only requirement is that the virtual machine must come with the Hepsia hosting Control Panel, via which you’ll be able to activate Varnish for any of your sites with only a few clicks. Each plan includes a different amount of memory for data caching purposes, but you’ll have no less than several hundred megabytes, which is sufficient even for multiple large-sized websites. Soon after you activate the Varnish platform, it’ll begin caching the content that your visitors access, so you’ll notice the much faster website loading speeds and the decreased load on your server very soon. Varnish will permit you to use a less costly VPS, as you will not need that many resources to guarantee the correct operation of your websites even if you have large sites with plenty of visitors. Maximum results are accomplished if the websites that use Varnish use also a dedicated IP address.
Varnish in Dedicated Servers
If you order a dedicated server with the Hepsia hosting Control Panel, you will acquire the Varnish data caching platform at no additional cost and you will exert full control over it through an amazingly user-friendly GUI – you’ll be able to start, to terminate or to reboot an instance, to check an elaborate system log, to delete the cached files associated with any site and much, much more. The Varnish caching platform will have several GB of virtual memory at its disposal, so even if you manage large-size sites with numerous visitors, you will notice the much faster page load times and the lowered server load. This will happen shortly after you start using Varnish, as it will require some time to cache the pages that visitors browse. You can take full advantage of the platform’s capabilities in case the Internet sites that are using it use also a dedicated IP address, but owing to the fact that your server includes a couple of IP addresses by default, you won’t need to pay anything on top of the monthly fee for the server itself.
