Varnish is a web application accelerator tool, which has been gaining a lot in popularity lately, because it can increase the speed of any Internet site, sometimes even by 100%, depending on the content. This tool is sometimes called an HTTP reverse proxy too and is used to lower the overall load on the physical server and to accelerate the access speed for the site visitors. Every time a visitor loads a page on a specific Internet site, the browser request is handled by the web server and the requested content is served as a reply. If the Varnish accelerator is enabled, it caches the web pages that the website visitor browses and if any of them is opened once again, it’s fetched by Varnish and not by the server directly. The increase in the performance is due to the fact that the accelerator handles the browser requests considerably faster than any web server, which results in much faster browsing speeds for the users. In case any data is changed meanwhile, the cached webpages will also be updated the next time somebody tries to access them.
Varnish in Shared Hosting
If you host your websites under a shared hosting account with our company, you will be able to activate Varnish with several mouse clicks via your hosting Control Panel. The platform is offered as an upgrade with all our plans and you can choose how many websites will use it and the maximum storage space that will be used for the cached data. The two upgradeable features in the Upgrades section of the Control Panel are the amount of system memory and the number of instances and they aren’t tied directly to each other, so you can decide whether you need lots of memory for a single large-sized site or less memory for multiple smaller ones. You can make use of the full potential of the Varnish caching platform in case the sites use a dedicated IP. Using the Control Panel, you can swiftly start/reboot/terminate an instance, clear the cached files independently for each site that employs the Varnish platform or view a comprehensive log file.
Varnish in Semi-dedicated Servers
All our Linux semi-dedicated service include Varnish by default, so you can take advantage of the accelerator and accelerate the loading speed of any website that you host on our semi-dedicated servers. You’ll get 64 megabytes of memory dedicated to the Varnish accelerator at no extra cost and you can enable an instance with no more than a couple of mouse clicks via the Hepsia hosting Control Panel, which comes with the semi-dedicated packages. If you need more memory, the latter is offered in increments of 32 MB through the Control Panel’s Upgrades section and it will be available to you instantaneously. You can also add more instances as a separate upgrade, so you can choose whether lots of data will be cached for one site or whether the memory will be utilized by multiple sites. The Hepsia Control Panel will allow you to reboot or to remove any instance, to check the system log file associated with it or to clear the cached content using one-click controls. To take full advantage of the Varnish accelerator, you can get a dedicated IP for the Internet sites that will employ it.
Varnish in VPS Servers
We offer Varnish with all Hepsia-managed VPS servers, so if you get a VPS with this hosting Control Panel, you’ll be able to make use of the content caching platform at no additional cost. Varnish can utilize different amounts of memory for data caching purposes based on the particular sever setup that you have selected during the order process, but in any case, this amount won’t be less than several hundred MB. This is quite enough to improve the work of a handful of regularly visited sites, so the faster website browsing speeds and the lowered server load will be perceptible. The result may not be detectable straight away, as Varnish will require a certain amount of time to cache the content that visitors browse, but soon after you set it up, you will witness its full potential. This caching platform will permit you to use a less powerful Virtual Private Server and to give less money to get the same performance you’d get with a higher-end virtual machine without Varnish.
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 extra fee and you’ll have total control over it through an extremely simple-to-use interface – you’ll be able to start, to stop or to restart an instance, to check a detailed log, to clear the cached files for any website and much, much more. The Varnish platform will have several gigabytes of system memory at its disposal, so even if you’ve got resource-absorbing sites with lots of visitors, you will notice the tremendously faster website load speeds and the less load. This will happen shortly after you begin using the Varnish platform, as it will need a certain amount of time to cache the content that people request. You can take full advantage of the platform’s capability if the Internet sites that are using it also use a dedicated IP, but owing to the fact that your dedicated server comes with several IPs by default, you won’t need to pay anything on top of the monthly charge for the server itself.
