Varnish is a web accelerator tool, which has been gaining a lot of popularity lately, as it can increase the loading speed of any Internet site, sometimes even by one hundred percent, depending on the content. This tool is occasionally referred to as a caching HTTP reverse proxy as well and is used to lower the overall load on the physical server and to improve the access speed for the site visitors. Every time a visitor accesses a page on a specific site, the browser request is processed by the web server and the requested information is returned as a reply. If the Varnish accelerator is activated, it caches the pages that the site visitor opens and if any of them is loaded again, it is served by Varnish and not by the web server directly. The boost in the performance comes from the fact that the accelerator handles the browser requests considerably quicker than any web server, which leads to much faster browsing speeds for the site visitors. In case any data is modified in the meantime, the cached webpages will also be updated the next time someone attempts to open them.

Varnish in Shared Web Hosting

If you host your websites under a shared web hosting account with us, you’ll be able to activate Varnish with several clicks via your Control Panel. The caching platform is available as an optional upgrade with all our shared hosting packages and you can select how many sites will use it and the maximum storage space that will be used 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’re not directly linked to each other, so you can decide if you need a lot of memory for one large-sized website or less memory for multiple smaller ones. You can take advantage of the full potential of the Varnish caching platform in case the websites use a dedicated IP. Using the Control Panel, you can easily start/reboot/stop an instance, delete the cached data independently for each site which employs the Varnish platform or see an elaborate system log.

Varnish in Semi-dedicated Servers

The Linux semi-dedicated hosting plans that we are offering will permit you to employ Varnish as soon as your brand new semi-dedicated account is active, as the platform is available by default. 64 MB of system memory will be allocated to Varnish the second your account is activated, so you can take advantage of this workload distribution software once your site has been published on the Internet. In case you are in need of more memory, you can get 32 megabytes at a time from the Upgrades section of the Hepsia hosting Control Panel and it will be assigned to your semi-dedicated server momentarily. You can also increase the number of the websites that use Varnish, or the so-called ‘instances’, which are not directly linked to the amount of system memory that you use, which goes to say that you will enjoy more flexibility. The caching platform will greatly reduce the load on the semi-dedicated server caused by your websites, so your visitors can enjoy fast-opening pages. You’ll be able to manage the Varnish caching platform without any effort via your Control Panel using quick-access buttons. You’ll be able to start/shut down any of the instances that you have, to clear the cached content for any of your Internet sites or to check system log files.

Varnish in VPS Servers

The Varnish caching platform comes by default with all Linux VPS hosting plans that we offer on the condition that the machine is ordered with the Hepsia Control Panel, so you can enhance the work of your sites with only a few clicks. The more powerful the package, the more memory Varnish will have at its disposal, but even with a lower-end package, the caching platform will be able to utilize several hundred MB, so even if you have a handful of websites, you will notice an enormous decrease in the overall server load and a much faster site loading speed. The Varnish caching platform will need to work for a little while as the users browse the web pages and as soon as the site content has been cached, you’ll observe the effect. One of the advantages of employing Varnish is that a less powerful and less expensive VPS plan will accomplish the exact same job as a more pricey one without the caching platform, so not only will your Internet sites perform significantly better, but you will also spare some cash.

Varnish in Dedicated Servers

When you need a powerful web hosting solution and you get one of the Linux dedicated servers that we are offering, you’ll be able to use the Varnish content caching platform to boost the work of your Internet sites at no extra fee as long as the dedicated machine is ordered with our advanced Hepsia Control Panel. Its easy-to-navigate interface will enable you to keep an eye on system processes, to delete the cache or to reboot any instance with one single click of the mouse. The smallest amount of memory that the Varnish caching platform can use to cache site content is 3 GB, which is quite enough for a huge selection of resource-hungry Internet sites, so your dedicated server will be able to cope with a tremendous system load while your Internet site visitors are having a smooth web browsing experience. As your dedicated machine will come with a number of dedicated IPs, you’ll be able to use Varnish’s full capacity.
