Varnish is a web app accelerator tool, which has been gaining a lot in popularity in recent years, as it can increase the loading speed of any site, at times even by one hundred percent, depending on the content itself. This tool is sometimes called a caching HTTP reverse proxy too and is used to decrease the overall load on the server and to enhance the access speed for the website visitors. Whenever a visitor loads a page on a particular website, the web browser request is processed by the web server and the requested information is delivered as a response. If the Varnish accelerator is activated, it caches the pages that the website visitor browses and in case any of them is opened for a second time, it is delivered by Varnish and not by the server directly. The performance boost is due to the fact that the accelerator processes the browser requests tremendously faster than any web server, which results in much faster browsing speeds for the website visitors. If any content is modified in the meantime, the cached pages will also be ‘refreshed’ the next time someone tries to access them.
Varnish in Shared Hosting
Varnish comes as an optional upgrade with all our Linux shared hosting. You can add it to your account through the Hepsia hosting Control Panel, which comes with all shared plans and you’ll get an amazingly user-friendly GUI, which will give you full control over the content caching platform. Using 1-click fast-access buttons, you can restart or terminate any of the instances, i.e. Varnish will no longer work for a certain Internet site. You can also view a detailed system log or delete the cache for any of the Internet sites. When you add Varnish to your hosting package, you’ll be able to choose the total amount of memory that will be at your disposal for content caching purposes and how many sites will use Varnish. You can always get more memory in increments of 32 MB and, for best performance, you can assign a dedicated IP to the websites that will use Varnish. This will allow you to take full advantage of your Internet sites and to have many happy site visitors.
Varnish in Semi-dedicated Servers
The Varnish caching platform is included in the default set of services that you will obtain when you decide to host your Internet sites under a semi-dedicated server account. You can configure it for any of your sites through our cutting-edge Hepsia hosting Control Panel. The default amount of memory that the Varnish platform can use to cache data is 64 MB, but in case you decide that you want more, you can upgrade this memory from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, i.e. the number of the sites that can use this platform simultaneously. As these two features aren’t tied to each other, you can use a few sites with the default amount of memory or you can get more memory in increments of 32 megabytes and use all of it for a single Internet site. The Varnish caching platform works best if you use a dedicated IP for the websites that utilize its power. Hepsia will give you an easy way of restarting any instance. In addition, you’ll be able to delete the cached files with just one single click of the mouse.
Varnish in VPS Servers
You can use Varnish with each of our VPS server plans at no additional fee, since the content caching platform is pre-installed and is available by default. The only prerequisite is that the VPS server must come with the Hepsia Control Panel, through which you’ll be able to set up Varnish for any of your sites with just a few clicks of the mouse. Each VPS package comes with a different amount of memory for data caching purposes, but you will get at least several hundred MB, which is enough even for several popular websites. Soon after you enable the Varnish platform, it’ll begin caching the content that your site visitors open, so you will notice the considerably better web page loading times and the less load on the machine very soon. Varnish will allow you to use a less pricey VPS server, since you won’t require that much power to sustain the correct operation of your Internet sites even if you own resource-requiring Internet sites with plenty of visitors. Optimum results are achieved if the websites which use Varnish also use a dedicated IP address.
Varnish in Dedicated Servers
If you want the most powerful web hosting solution and you get any of the Linux dedicated servers offered by us, you’ll be able to use Varnish to optimize the overall performance of your sites at no extra cost on the condition that the server is ordered with our cutting-edge Hepsia hosting Control Panel. Its simple-to-work-with GUI will allow you to keep an eye on system processes, to delete the cached contents or to reboot any instance with one click of the mouse. The minimal amount of memory that the platform can employ to cache content is 3 gigabytes, which is quite enough for a vast selection of traffic-heavy websites, so your dedicated server will be able to cope with a massive load while your site visitors are having a smooth browsing experience. Since your machine will include several different dedicated IPs, you’ll be able to make use of Varnish’s full potential.
