Varnish is a web accelerator platform, which caches content for faster access. It’s occasionally referred to as an HTTP reverse proxy too and it works between a web server and a browser. When a site visitor loads a certain page, the content is requested by the web browser, and then the server handles this browser request and delivers the required content. If Varnish is activated for a given site, it will cache its pages at the first visit and if the visitor accesses a cached page again, the info will be delivered by the caching platform and not by the server. The improved loading speed is a result of the much faster response speed that the Varnish platform offers compared with any web server software. Of course, this does not mean that the site visitors will continue seeing the same content over and over again, because any change on any of the web pages is reflected in the content that Varnish stores in its system memory.
Varnish in Cloud Website Hosting
In case you host your sites in a cloud website hosting account with us, you will be able to add Varnish with a few clicks through your hosting Control Panel. The data caching platform is offered as an optional upgrade with all our shared web hosting plans and you can select how many websites will use it and the total storage space that will be available for the cached data. 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 are not linked directly to each other, so you can decide whether you need lots of memory for a single large-sized website or less memory for several smaller ones. You can take advantage of the full potential of Varnish in case the sites use a dedicated IP address. With the hosting Control Panel, you can quickly start/restart/remove an instance, clear the cached contents independently for each site which employs Varnish or view a comprehensive system log.
Varnish in Semi-dedicated Servers
Varnish is part of the default service set that you’ll obtain if you choose to host your sites under a semi-dedicated server account. You can configure it for any of your Internet sites via our cutting-edge Hepsia hosting Control Panel. The default amount of system memory that the Varnish caching platform can use to cache content is 64 MB, but in case you decide that you need more, you can upgrade this memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, in other words – the number of the websites that can use this platform simultaneously. As these two features aren’t bound to each other, you can use a few Internet sites with the default amount of memory or you can order more memory in increments of 32 MB and use all of it for one single website. The Varnish platform performs best when you use a dedicated IP address for the websites that utilize its power. Hepsia will provide you with a simple means of rebooting any instance. What’s more, you’ll be able to delete the cached files with just one click.
Varnish in VPS Servers
You can use the workload balancing potential of Varnish with any of our VPS plans if you select Hepsia as your hosting Control Panel. The Varnish platform comes by default and the memory that it’ll be able to use to cache the content of your sites is dependent on the given Virtual Private Server package that you have picked, but even with the lower-end packages, you will have at least several hundred megabytes of memory at your disposal solely for content caching purposes. This amount is sufficient enough to improve the overall performance of multiple sites. It will take a little time for you to distinguish the results, since the Varnish platform caches the content that site visitors access, but soon after that you’ll notice the significantly lowered load on your Virtual Private Server and the accelerated Internet site load speed. The Varnish platform will permit you to use a lower-end plan for websites which would usually require a more costly web hosting service.
Varnish in Dedicated Servers
If you want the most powerful website hosting solution and you acquire any of the dedicated web hosting plans that we are offering, you will be able to use Varnish to boost the work of your Internet sites at no extra fee on the condition that the server is ordered with our innovative Hepsia Control Panel. Its simple-to-navigate GUI will permit you to monitor platform processes, to delete the cached files or to reboot any instance with one single click. The smallest amount of memory that the Varnish caching platform can use to cache site content is 3 GB, which is more than enough for an enormous number of resource-intensive Internet sites, so your server will be able to cope with a substantial system load while your site visitors are enjoying a seamless browsing experience. As your dedicated server will include a number of dedicated IPs, you’ll be able to make use of Varnish’s maximum potential.
