Varnish is a web accelerator platform, which caches information for the sake of quicker response times. It is sometimes referred to as an HTTP reverse proxy as well and it works between a web server and a web browser. When a website visitor accesses a given web page, the content is requested by the web browser, and then the web server handles this request and returns the requested content. If Varnish is enabled for a site, it will cache the pages on the first request and if the user opens a cached page again, the information will be delivered by the accelerator platform instead of the web server. The increased loading speed is an end result of the much faster response speed that the Varnish platform offers as compared with any web server software. At the same time, this doesn’t mean that the site visitors will continue seeing the same content again and again, because any change on any of the pages is reflected in the content that Varnish caches in its system memory.
Varnish in Shared Website Hosting
If you host your sites under a shared website hosting account with us, you’ll be able to activate Varnish with a couple of clicks of the mouse through your hosting Control Panel. The platform is offered as an upgrade with all our web hosting packages and you can select how many sites will use it and the total amount of system memory that will be used for the cached data. The two features that can be upgraded in the Control Panel’s Upgrades section are the number of instances and the amount of memory and they aren’t directly linked to each other, so you can decide if you want plenty of memory for a single large-scale website or less memory for several smaller ones. You can take advantage of the full potential of the Varnish caching platform if the sites use a dedicated IP address. Using the Control Panel, you can swiftly start/restart/delete an instance, clear the cached contents independently for each site that employs Varnish or see an exhaustive system log file.
Varnish in Semi-dedicated Servers
Varnish is included by default with all Linux semi-dedicated servers that we’re offering and you can use it for load distribution purposes. It’s available in your Hepsia Control Panel. The Varnish caching platform comes with 64 MB of system memory for cached data storing purposes and you can employ it with any Internet site that you host in the semi-dedicated server account. In case you need more, you can increase the memory allocation. The memory itself is available in increments of 32 MB through the Upgrades section of the Control Panel. The exact same Upgrades section will enable you to enable more instances too, if you want to use Varnish with more Internet sites. The two things can be added independently – you can cache the content of a single traffic-heavy Internet site or run several sites with the default memory quota. You can get the most out of Varnish in case you’ve got a dedicated IP address and you can get one with your semi-dedicated server package as well. The Hepsia Control Panel will give you complete control over the caching platform and, with no more than one single mouse click, you’ll be able to delete the cached contents, to check a system log file or to reboot an instance.
Varnish in VPS Servers
The Varnish content caching platform is included by default with each of the Linux VPS hosting service offered by us on the condition that the virtual server is ordered with the Hepsia hosting Control Panel, so you can boost the work of your sites with just a few mouse clicks. The more powerful the package, the more memory Varnish will have at its disposal, but even with a low-end package, the platform will be able to utilize several hundred MB, so even if you’ve got a handful of Internet sites, you’ll notice a considerable reduction in the server load and a considerably faster web page loading speed. The Varnish platform will need to work for a while as the visitors navigate the site and as soon as the site content has been cached, you will distinguish the effect. One of the upsides of employing Varnish is that a lower-end and less pricey Virtual Private Server package will accomplish the exact same job as a more high-priced one without the platform, so not only will your Internet sites perform better, but you’ll also save a certain amount of money.
Varnish in Dedicated Servers
When you want a powerful website hosting solution and you obtain any of the Linux dedicated service offered by us, you can use Varnish to optimize the performance of your Internet sites at no extra cost as long as the dedicated machine is ordered with our next-generation Hepsia hosting Control Panel. Its intuitive graphical interface will permit you to keep track of platform processes, to delete the cache or to restart any instance with one single click of the mouse. The minimal amount of system memory that the caching platform can use to cache site content is 3 GB, which is quite enough for a huge number of heavy Internet sites, so your server will be able to cope with an enormous load while your website visitors are having a seamless browsing experience. Since your server will come with several different dedicated IP addresses, you will be able to make use of Varnish’s full capacity.
