Varnish is a website accelerator tool, which has been gaining a lot of popularity in recent years, as it can increase the load speed of any site, at times even by 100 percent, depending on the content itself. This tool is occasionally called an HTTP reverse proxy too and is used to lower the overall load on the server and to boost the browsing speed for the site visitors. Every time a visitor loads a page on a particular Internet site, the browser request is processed by the web server and the requested information is delivered as a reply. If Varnish is enabled, it caches the web pages that the visitor opens and in case any of them is opened for a second time, it’s delivered by Varnish and not by the web server directly. The performance boost is due to the fact that the accelerator handles the browser requests substantially faster than any web server, which results in much faster browsing speeds for the site visitors. If any content is changed in the meantime, the cached pages will also be updated the next time someone opens them.
Varnish in Shared Website Hosting
Varnish comes as an optional upgrade with each of our shared website hosting plans. You can add it to your website hosting account through the Hepsia hosting Control Panel, which comes with all shared web hosting plans and you will get a very simple-to-use interface, which will grant you full control over the caching system. Using 1-click fast-access controls, you can restart or cancel any of the instances, i.e. Varnish will no longer work for a certain site. You can also view a detailed system log or erase the cache for any of the websites. When you add Varnish to your shared web hosting plan, you’ll be able to select the total amount of system memory that will be available to you for data caching purposes and how many websites will use Varnish. You can always add more memory in increments of 32 megabytes and, for top performance, you can assign a dedicated IP address to the sites that will use Varnish. This will permit you to take full advantage of your websites and to have a lot of pleased visitors.
Varnish in Semi-dedicated Servers
The Varnish platform is included in the default set of services that you’ll receive if you decide to host your Internet sites in a semi-dedicated server account. You can set it up for any of your sites via our next-generation Hepsia Control Panel. The default system memory that Varnish can use to cache content is 64 megabytes, but in case you decide that you want more, you can upgrade this memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, in other words – the number of the Internet sites that can use this caching platform simultaneously. As these two things aren’t bound to each other, you can use a few websites with the default memory or you can get more memory in increments of 32 MB and use all of it for a single site. The Varnish platform works best if you assign a dedicated IP address to the sites that utilize its power. The Hepsia Control Panel will provide you with an easy way of rebooting any instance. Furthermore, you’ll be able to clear the cached contents with only one single mouse click.
Varnish in VPS Servers
You can use Varnish with all our VPS server packages at no additional fee, since the content caching platform is pre-installed and is included by default. The sole prerequisite is that the server must come with the Hepsia Control Panel, via which you will be able to activate Varnish for any of your sites with just a few clicks of the mouse. Each Virtual Private Server plan features a different amount of memory for caching purposes, but you will have minimum several hundred MB, which is sufficient even for several traffic-hungry websites. Shortly after you enable Varnish, it’ll begin caching the content that your visitors request, so you’ll notice the much faster webpage loading times and the decreased load on your virtual server very soon. The caching platform will permit you to use a less pricey virtual machine, since you will not need that much power to ensure the correct operation of your Internet sites even if you have popular websites with plenty of visitors. Optimum results are accomplished if the websites which use the Varnish caching platform also use a dedicated IP.
Varnish in Dedicated Servers
You can employ Varnish in order to enhance the loading speed of any website that’s hosted on a dedicated server with us when the Hepsia hosting Control Panel is pre-installed on the machine. Not only will you get the platform ready to be used at no additional fee, but you will also have full control over it via the Hepsia Control Panel’s intuitive GUI. It’ll take just one mouse click to start or stop an instance or to delete the cached data associated with any Internet site that is using the Varnish platform and in case you’re more knowledgeable, you can also view the platform’s system logs. Varnish comes with no less than 3 GB of system memory for website content caching purposes, so even in case you run an immense number of Internet sites on your dedicated server and they all use the Varnish caching platform, the improvement in their overall performance will be visible. You’ll simply have to wait for a little while till Varnish caches whatever content the visitors load on their end. The Varnish platform works best if the Internet sites use a dedicated IP, but owing to the fact that our dedicated servers include 3 free IP addresses, you will have everything you need.
