Varnish is a web app accelerator tool, which has been gaining a lot of popularity in recent years, as it can increase the speed of any website, at times even by 100 percent, based on the content. This tool is occasionally referred to as an HTTP reverse proxy as well and is used to lower the overall server load and to improve the access speed for the website visitors. Anytime a visitor accesses a page on a particular website, the browser request is handled by the web server and the requested data is sent as a response. If the Varnish accelerator is enabled, it caches the web pages that the site visitor opens and if any of them is loaded again, it’s delivered by Varnish and not by the server directly. The performance improvement comes from the fact that the accelerator processes the web requests substantially faster than any web server, which results in much faster browsing speeds for the website visitors. If any data is changed in the meantime, the cached webpages will also be ‘refreshed’ the next time somebody attempts to access them.

Varnish in Web Hosting

In case you host your websites under a web hosting account with us, you’ll be able to activate Varnish with a couple of mouse clicks via your Control Panel. The caching platform comes as an upgrade with all our plans and you can choose the number of the websites that will use it and the maximum storage space that will be used for the cached data. The two features that can be upgraded in the Control Panel’s Upgrades section are the number of instances and the amount of system memory and they’re not directly tied to each other, so you can choose if you want lots of memory for one single large-sized site or less memory for several smaller ones. You can make use of the full potential of the Varnish caching platform in case the websites use a dedicated IP. With the hosting Control Panel, you can effortlessly start/reboot/terminate an instance, delete the cached contents individually for each website that uses Varnish or view an elaborate system log.

Varnish in Semi-dedicated Hosting

Varnish is a feature, which comes as standard with all Linux semi-dedicated hosting offered by us and you can use it for load distribution purposes. It is available in your Hepsia hosting Control Panel. The content caching platform comes with 64 MB of system memory for cached data storing purposes and you can use it with any Internet site that you host in your account. If you’re in need of more than that, you can increase the system memory quota. The memory itself is available in increments of 32 megabytes in the Upgrades section of the Control Panel. The same Upgrades section will permit you to activate more instances too, in case you want to use the Varnish platform with more sites. The two upgrades can be added independently – you can cache the content of one regularly visited website or use several different websites with the default memory allocation. You can take full advantage of Varnish in case you use a dedicated IP and you can get one with your semi-dedicated package as well. Hepsia will grant you full control over the platform and, with no more than one click of the mouse, you’ll be able to clear the cached contents, to view a system log or to reboot an instance.

Varnish in VPS Hosting

Varnish comes by default with each of the Linux VPS hosting that we offer as long as the server is ordered with the Hepsia Control Panel, so you can enhance the performance of your sites with only a few clicks of the mouse. The more powerful the package, the more system memory will be available to Varnish, but even with a low-end package, the caching platform will be able to utilize several hundred MB, so even if you have a number of websites, you will notice a serious reduction in the server load and a significantly faster web page loading speed. The Varnish platform will need to work for a little while as the users navigate the web pages and once the site content has been cached, you will notice the effects. One of the benefits of employing Varnish is that a less powerful and less pricey Virtual Private Server plan will accomplish the very same job as a more costly one without the platform, so not only will your sites work better, but you’ll also spare some cash.

Varnish in Dedicated Web Hosting

All Linux dedicated web hosting that are ordered with the tailor-made Hepsia web hosting Control Panel include Varnish, which is one of the pre-installed platforms that you will get with the dedicated machine. The Varnish data caching platform can be activated and administered with ease from Hepsia’s user-friendly interface and, with no more than a click, you can see a comprehensive log, add or reboot an instance, delete the cache associated with any Internet site and much more. Shortly after you enable the Varnish platform for a specific domain or sub-domain, it will begin caching the pages loaded by your website visitors and once it has cached enough content, you will perceive a significantly faster site performance as well as a lowered load on your dedicated machine. With Varnish-dedicated system memory starting at three gigabytes, you’ll be able to use the software platform for load balancing purposes even if you host plenty of sites on the dedicated server.
