Varnish is a web accelerator, which has been gaining a lot of popularity lately, because it can increase the load speed of any website, at times even by 100 percent, based on the content itself. This tool is sometimes called a caching HTTP reverse proxy too and is used to reduce the overall load on the server and to increase the browsing speed for the website visitors. Each time a visitor accesses a page on a certain site, the browser request is processed by the web server and the requested info is returned as a response. If Varnish is enabled, it caches the web pages that the site visitor opens and in case any of them is opened once more, it is fetched by Varnish and not by the server directly. The increase in the performance comes from the fact that the accelerator handles the web requests tremendously quicker than any web server, which leads to much faster browsing speeds for the visitors. In case any content is modified meanwhile, the cached web pages will also be ‘refreshed’ the next time someone attempts to access them.
Varnish in Hosting
If you host your sites under a hosting account with us, you will be able to activate Varnish with a few clicks of the mouse from your hosting Control Panel. The content caching platform is offered as an upgrade with all our hosting plans and you can select how many websites will use it and the total 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 linked directly to each other, so you can choose whether you want plenty of memory for one single large-sized site or less memory for multiple smaller ones. You can use the full potential of the Varnish platform if the websites use a dedicated IP. Using the Control Panel, you can swiftly start/reboot/shut down an instance, clear the cached contents independently for each website that employs the Varnish platform or check an exhaustive log.
Varnish in Semi-dedicated Servers
Varnish comes by default with all Linux semi-dedicated hosting plans that we offer and you can use it for load distribution purposes. It is available in your Hepsia Control Panel. The platform comes with 64 MB of system memory for cached content storing purposes and you can employ it with any website that you host in the semi-dedicated account. In case you’re in need of more, you can increase the system memory allowance. The memory itself is available in increments of 32 MB in the Upgrades section of the Control Panel. The very same section will allow you to create more instances too, if you’d like to use Varnish with more websites. The two things can be ordered separately – you can cache the content of a single large site or use a number of websites with the default memory allocation. You can take full advantage of Varnish in case you’ve got a dedicated IP address and you can get one with your semi-dedicated server plan as well. Hepsia will grant you full control over the caching platform and, with no more than one single click, you will be able to clear the cached files, to view a system log file or to restart an instance.
Varnish in VPS Servers
We provide Varnish with all of the Hepsia-equipped Linux VPS servers, so in case you purchase a server with this web hosting Control Panel, you’ll be able to take full advantage of the content caching platform at no extra cost. Varnish can use different amounts of system memory for data caching purposes depending on the very VPS plan that you’ve chosen during the VPS order process, but at any rate, this amount won’t be less than several hundred MB. This is quite enough to enhance the work of a handful of traffic-heavy websites, so the faster web page browsing speeds and the reduced load on the machine will be perceptible. The effect may not be evident momentarily, since the Varnish platform will require some time to cache the site content that users browse, but soon after you enable it, you’ll observe its full capacity. This platform will allow you to use a lower-end VPS and to give less cash to get the very same performance you’d get with a more powerful machine without Varnish.
Varnish in Dedicated Servers
You can employ Varnish in order to improve the loading speed of any website that’s hosted on a dedicated server with us if the Hepsia Control Panel is pre-installed on the machine. Not only will you get the caching platform ready for use at no extra charge, but you’ll also have complete control over it via the Hepsia Control Panel’s easy-to-navigate GUI. It’ll take only one click of the mouse to start or terminate an instance or to clear the cached data associated with any site that is using the Varnish platform and in case you’re more tech-savvy, you can also view the platform’s logs. Varnish comes with no less than three gigabytes of virtual memory for site content caching purposes, so even if you run an immense number of sites on your machine and they all use the caching platform, the difference in their performance will be distinguishable. You will just need to wait for a while till Varnish caches whatever web pages the site visitors access on their end. The Varnish platform performs best when the Internet sites use a dedicated IP address, but due to the fact that our dedicated servers come with 3 free IP addresses, you will have all that you need.
