Varnish is a website accelerator, which has been gaining a lot of popularity lately, because it can increase the loading speed of any Internet site, at times even by 100 percent, depending on the content. This tool is occasionally called an HTTP reverse proxy too and is used to decrease the overall server load and to enhance the access speed for the site visitors. Every time a visitor accesses a page on a specific website, the web browser request is taken care of by the web server and the requested info is delivered as a reply. If Varnish is enabled, it caches the web pages that the visitor opens and in case any of them is accessed once more, it is fetched by Varnish and not by the web server directly. The improvement in the performance comes from the fact that the accelerator processes the web requests tremendously quicker than any web server, which leads to much faster browsing speeds for the website visitors. If any content is changed in the meantime, the cached pages will also be ‘refreshed’ the next time someone tries to open them.
Varnish in Cloud Hosting
In case you host your websites in a cloud hosting account with us, you’ll be able to activate Varnish with several clicks of the mouse via your Control Panel. The platform comes as an upgrade with all our hosting packages and you can select how many sites will use it and the maximum storage space that will be used for the cached data. The two upgradeable features in the Control Panel’s Upgrades section are the amount of system 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-size website or less memory for multiple smaller ones. You can take advantage of the full potential of Varnish if the websites use a dedicated IP. Using the hosting Control Panel, you can quickly start/restart/delete an instance, clear the cached data independently for each site that uses Varnish or see a detailed system log.
Varnish in Semi-dedicated Hosting
Varnish is included by default with all Linux semi-dedicated hosting packages that we offer and you can use it for load balancing purposes. It is available in your Hepsia hosting Control Panel. The caching platform comes with 64 megabytes of system memory for cached data storing purposes and you can use it with any Internet site that you host in the semi-dedicated account. If you need more than that, you can increase the memory allocation. The memory itself is offered in increments of 32 megabytes in the Upgrades section of the Control Panel. The very same section will allow you to create more instances as well, if you want to use the Varnish platform with more Internet sites. The two upgrades can be ordered independently – you can cache the content of one single resource-hungry website or use several different websites with the default memory. You can take full advantage of the Varnish platform in case you have a dedicated IP address and you can order one with your semi-dedicated server plan as well. The Hepsia Control Panel will give you complete control over the platform and, with no more than one single mouse click, you will be able to delete the cached data, to see a system log or to restart an instance.
Varnish in Dedicated Web Hosting
If you order a dedicated server with the Hepsia Control Panel, you’ll get Varnish at no extra charge and you will exert total control over it via an exceptionally time and effort saving GUI – you’ll be able to start, to terminate or to reboot an instance, to check an elaborate log, to delete the cached data associated with any site and much more. The Varnish caching platform will have several GB of virtual memory at its disposal, so even if you host resource-absorbing sites with a huge number of visitors, you’ll notice the tremendously faster page load speeds and the decreased load. This will happen soon after you start using Varnish, as it will need a certain amount of time to cache the site content that visitors access. You can make the most of the platform’s capability in case the Internet sites that are using it use also a dedicated IP address, but since your dedicated server comes with several IPs by default, you won’t have to pay anything on top of your monthly fee for the server itself.
