Learn precisely what Varnish is. Discover a lot more about web accelerators and their function.
Varnish is a web application accelerator, which has been gaining a lot in popularity lately, because it can increase the loading speed of any site, sometimes even by 100 percent, based on the content. This tool is occasionally referred to as a caching HTTP reverse proxy as well and is used to reduce the overall server load and to accelerate the browsing speed for the website visitors. Each time a visitor accesses a page on a particular Internet site, the browser request is handled by the web server and the requested info is delivered as a reply. If the Varnish accelerator is enabled, it caches the web pages that the site visitor browses and in case any of them is opened again, it’s delivered by Varnish and not by the server directly. The performance increase comes from the fact that the accelerator handles the web requests tremendously quicker than any web server, which results in much faster browsing speeds for the website visitors. If any data is updated in the meantime, the cached web pages will also be ‘refreshed’ the next time someone attempts to access them.
Varnish in Cloud Web Hosting
You can take advantage of Varnish’s full potential and enhance your sites’ loading speed irrespective of the cloud web hosting
package that you’ve selected and you can activate and set up the data caching platform with a few clicks of the mouse via the simple-to-work-with graphical interface offered by our next-generation Hepsia Control Panel. During the process, you’ll be able to choose two separate things – how many sites will use the Varnish platform, in other words – the number of instances, and how much content will be cached, i.e. the amount of memory. The latter is offered in increments of 32 MB and is not linked to the number of instances, so you can use more instances and less memory and the other way around. In case you’ve got lots of content on a given Internet site and you get many site visitors, more memory will give you better results. You may also consider using a dedicated IP address for the Internet sites that will use Varnish. Hepsia will offer you simple one-click controls for disabling or rebooting any instance, for erasing the cache for any Internet site and for checking detailed system logs.
Varnish in Semi-dedicated Servers
The Varnish content caching platform is an essential part of the standard service set that you’ll obtain if you choose to host your Internet sites under a semi-dedicated server
account. You can activate it for any of your websites via our cutting-edge Hepsia Control Panel. The default amount of system memory that the Varnish platform can use to cache data is 64 megabytes, but in case you decide that you need more, you can upgrade this amount from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, in other words – the number of the websites that can use this caching platform at the same time. As these two things aren’t linked to each other, you can use several Internet sites with the default memory or you can order more memory in increments of 32 MB and use all of it for a single web site. The Varnish platform performs best when you use a dedicated IP address for the sites that utilize its power. Hepsia will give you an easy means of restarting any instance. What’s more, you’ll be able to clear the cached files with only a click.
Varnish in VPS Servers
You can take advantage of Varnish with each of our VPS server
plans at no extra cost, as the caching platform is pre-installed and is available by default. The one and only condition is that the Virtual Private Server must be ordered with the Hepsia Control Panel, through which you’ll be able to set up Varnish for any of your sites with only a couple of mouse clicks. Each package comes with a different amount of system memory for data caching purposes, but you’ll get at least several hundred MB, which is quite sufficient even for multiple large-scale sites. Soon after you set up Varnish, it will start caching the content that your site visitors request, so you’ll notice the significantly faster page load times and the reduced load on your VPS server very soon. Varnish will allow you to use a less expensive VPS, since you will not need that much power to warrant the proper operation of your Internet sites even if you have traffic-consuming sites with numerous visitors. Optimal results are accomplished if the websites which use the Varnish platform use also a dedicated IP.
Varnish in Dedicated Servers
When you need the most powerful hosting solution and you order one of the dedicated web hosting plans
that we are offering, you’ll be able to use the Varnish platform to improve the performance of your sites at no extra charge as long as the dedicated server is ordered with our cutting-edge Hepsia Control Panel. Its easy-to-navigate graphical interface will enable you to keep an eye on system processes, to clear the cached data or to restart any instance with a click. The smallest amount of system memory that Varnish can use to cache content is 3 GB, which is quite enough for a large number of resource-demanding sites, so your dedicated server will be able to cope with an enormous load while your website visitors are enjoying a seamless web browsing experience. Since your server will include a number of dedicated IP addresses, you will be able to use Varnish’s full capacity.
