Varnish is a website accelerator, which has been gaining a lot of popularity lately, as it can increase the loading speed of any Internet site, at times even by 100 percent, based on the content. This tool is occasionally referred to as a caching HTTP reverse proxy too and is used to decrease the overall load on the physical machine and to accelerate the access speed for the website visitors. Every time a visitor accesses a page on a particular Internet site, the browser request is taken care of by the web server and the requested content is delivered as a reply. If the Varnish accelerator is activated, it caches the web pages that the visitor opens and if any of them is loaded again, it’s served by Varnish and not by the server directly. The boost in the performance is due to the fact that the accelerator handles the web requests considerably faster than any web server, which leads to much faster browsing speeds for the users. In case any data is updated meanwhile, the cached webpages will also be ‘refreshed’ the next time somebody tries to access them.

Varnish in Hosting

If you host your Internet sites in a hosting account with us, you will be able to activate Varnish with several clicks via your hosting Control Panel. The caching platform is available as an upgrade with all our plans and you can choose how many websites will use it and the total storage space that will be available for the cached content. 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 directly tied to each other, so you can decide if you need a lot of memory for one single large-size site or less memory for several smaller ones. You can unlock the full potential of the Varnish platform if the websites use a dedicated IP address. With the Control Panel, you can easily start/reboot/terminate an instance, delete the cached content independently for each site which employs Varnish or view an elaborate system log file.

Varnish in Semi-dedicated Hosting

The Linux semi-dedicated hosting packages that we’re offering will permit you to employ Varnish once your brand new semi-dedicated server account has been created, since the content caching platform is available by default. 64 megabytes of system memory will be assigned to Varnish the moment your account is activated, so you can take advantage of this workload distribution software once your website has been published on the Internet. In case you need more memory, you can order 32 MB at a time from the Hepsia Control Panel’s Upgrades section and it will be allocated to your semi-dedicated machine instantly. You can also increase the number of the sites that employ Varnish, or the so-called ‘instances’, which are not directly tied to the amount of memory that you use, which goes to say that you will enjoy more flexibility. The caching platform will considerably lower the load on the server generated by your sites, so your visitors can enjoy fast-loading pages. You’ll be able to manage Varnish without any effort from the Control Panel using fast-access controls. You will be able to start/stop any of the instances that you have, to clear the cached files for any of your Internet sites or to check system log files.

Varnish in VPS Hosting

You can use the load balancing capabilities of Varnish with all our Linux VPS hosting packages when you select Hepsia as your hosting Control Panel. The caching platform is available by default and the memory that it’ll be able to utilize to cache your site content is dependent on the specific Virtual Private Server package that you have picked, but even with the less powerful packages, you’ll have no less than several hundred MB of system memory at your disposal only for data caching purposes. This amount is sufficient enough to improve the overall performance of numerous sites. It will take some time for you to detect the effects, as the Varnish platform caches the content that visitors browse, but after that you’ll notice the substantially less load on your virtual machine and the improved Internet site loading speed. Varnish will allow you to make use of a less powerful Virtual Private Server plan for Internet sites that would typically need a more high-priced hosting service.

Varnish in Dedicated Web Hosting

In case you order a dedicated server with the Hepsia hosting Control Panel, you’ll get the Varnish caching platform at no additional fee and you’ll exert total control over it through a really easy-to-work-with graphical interface – you’ll be able to start, to delete or to restart an instance, to browse an elaborate log, to delete the cached files associated with any website and much more. The Varnish platform will have several gigabytes of memory at its disposal, so even if you have resource-heavy Internet sites with multiple visitors, you will notice the significantly better website load times and the reduced load on the dedicated machine. This will happen shortly after you begin using Varnish, as it will need some time to cache the site content that visitors request. You can make the most of the platform’s capabilities if the sites that are using it also use a dedicated IP, but due to the fact that your dedicated server includes several IPs by default, you won’t have to pay anything on top of the monthly charge for the machine itself.
