Varnish is a web app accelerator, which has been gaining a lot in popularity lately, because it can increase the speed of any Internet site, at times even by one hundred percent, depending on the content itself. This tool is occasionally referred to as a caching HTTP reverse proxy too and is used to lower the overall server load and to boost the access speed for the site visitors. Each time a visitor loads a page on a particular website, the browser request is processed by the web server and the requested information is returned as a response. If the Varnish accelerator is enabled, it caches the web pages that the visitor browses and in case any of them is loaded once more, it’s delivered by Varnish and not by the web server directly. The performance boost comes from the fact that the accelerator handles the browser requests substantially quicker than any web server, which results in much faster browsing speeds for the users. In case any content is modified in the meantime, the cached web pages will also be ‘refreshed’ the next time someone tries to open them.
Varnish in Cloud Hosting
If you host your Internet sites under a cloud hosting account with our company, you will be able to activate Varnish with a couple of mouse clicks through your hosting Control Panel. The platform comes as an optional upgrade with all our web hosting plans and you can choose the number of the websites that will use it and the maximum storage space that will be available for the cached content. The two upgradeable features in the Control Panel’s Upgrades section are the number of instances and the amount of memory and they aren’t tied directly to each other, so you can choose if you want a lot of memory for one large-size website or less memory for multiple smaller ones. You can make use of the full potential of the Varnish platform in case the websites use a dedicated IP. With the Control Panel, you can swiftly start/reboot/discontinue an instance, delete the cached content independently for each website which uses Varnish or check an elaborate log file.
Varnish in Semi-dedicated Hosting
All our Linux semi-dedicated hosting come with Varnish by default, so you can make use of the website accelerator tool and increase the load speed of any site that you host on our semi-dedicated servers. You’ll get 64 megabytes of memory dedicated to Varnish at no additional fee and you’ll be able to add an instance with no more than a couple of clicks of the mouse via the Hepsia hosting Control Panel, which comes with the semi-dedicated server packages. In case you need more memory, the latter is offered in increments of 32 MB in the Control Panel’s Upgrades section and it will be at your disposal immediately. You can also order more instances as a separate upgrade, so you can choose whether a lot of data will be cached for one site or if the available memory will be utilized by several sites. The Hepsia Control Panel will enable you to reboot or to terminate any instance, to check the system log file for it or to delete the cached data using single-click controls. To get the most out of the Varnish accelerator, you can allocate a dedicated IP address to the websites that will use it.
Varnish in Dedicated Hosting
In case you order a dedicated server with the Hepsia Control Panel, you’ll acquire the Varnish caching platform at no additional cost and you will have complete control over it via a really easy-to-work-with interface – you will be able to start, to cancel or to restart an instance, to view an exhaustive system log, to clear the cache associated with any site and much more. Varnish will have several GB of virtual memory at its disposal, so even if you manage regularly visited Internet sites with a vast number of visitors, you will notice the tremendously faster site load times and the lowered load on your dedicated server. This will become a fact soon after you start using Varnish, as it will require a certain amount of time to cache the content that visitors access. You can make the most of the platform’s capacity if the sites that are using it use also a dedicated IP, but due to the fact that your server comes with a few IPs by default, you will not have to pay anything on top of the monthly fee for the server itself.
