Varnish is a web application accelerator, which has been gaining a lot of popularity in recent years, as it can increase the load speed of any site, sometimes even by 100 percent, depending on the content. This tool is occasionally called an HTTP reverse proxy as well and is used to decrease the overall load on the physical server and to accelerate the access speed for the website visitors. Whenever a visitor loads a page on a certain Internet site, the browser request is handled by the web server and the requested information is returned as a response. If the Varnish accelerator is enabled, it caches the web pages that the site visitor browses and in case any of them is accessed again, it’s delivered by Varnish and not by the web server directly. The boost in the performance comes from the fact that the accelerator handles the web requests significantly quicker than any web server, which leads to much faster browsing speeds for the users. In case any content is changed meanwhile, the cached web pages will also be ‘refreshed’ the next time somebody attempts to access them.
Varnish in Shared Web Hosting
In case you host your Internet sites under a shared web hosting account with our company, you will be able to activate Varnish with a few clicks through your hosting Control Panel. The caching platform is offered as an optional upgrade with all our hosting plans and you can choose how many sites will use it and the total amount of system memory that will be available for the cached data. The two features that can be upgraded in the Control Panel’s Upgrades section are the amount of system memory and the number of instances and they are not linked directly to each other, so you can decide if you need plenty of memory for one single large-scale website or less memory for several smaller ones. You can use the full potential of the Varnish platform in case the sites use a dedicated IP address. Using the Control Panel, you can quickly start/restart/delete an instance, clear the cached data individually for each site that uses Varnish or check a detailed log file.
Varnish in Semi-dedicated Servers
The Varnish caching platform is part of the basic set of services that you will acquire in case you choose to host your Internet sites in a semi-dedicated server account. You can activate it for any of your websites through our cutting-edge Hepsia Control Panel. The default memory that the Varnish platform can use to cache data is 64 megabytes, but if you decide that you need 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 sites that can use this platform at the same time. As these two things aren’t tied to each other, you can use a couple of 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 caching platform works best when you set a dedicated IP address for the Internet sites that utilize its power. Hepsia will give you an easy means of rebooting any instance. Furthermore, you will be able to clear the cached files with only one click.
Varnish in VPS Servers
Varnish is included by default with all Linux VPS plans that we’re offering on the condition that the machine is ordered with the Hepsia hosting Control Panel, so you can boost the overall performance of your websites with only a couple of clicks of the mouse. The more powerful the package, the more system memory will be available to Varnish, but even with a less powerful package, the caching platform will be able to utilize several hundred MB, so even if you’ve got several Internet sites, you will notice an enormous decrease in the server load and a much better webpage load speed. The platform will have to work for a little while as the users browse the site and as soon as the content has been cached, you’ll distinguish the effect. One of the benefits of employing Varnish is that a less powerful and less high-priced plan will accomplish the very same job as a more costly one without the caching platform, so not only will your Internet sites perform better, but you’ll also spare a certain amount of money.
Varnish in Dedicated Servers
In case you order a dedicated server with the Hepsia hosting Control Panel, you will acquire the Varnish content caching platform at no extra cost and you will exert full control over it through a very simple-to-use graphical interface – you’ll be able to start, to delete or to restart an instance, to view a detailed system log, to clear the cached files for any site and much more. The Varnish caching platform will have several GB of memory at its disposal, so even if you manage large-scale Internet sites with an enormous number of visitors, you will notice the tremendously faster web page load times and the reduced load on the machine. This will become a fact soon after you begin using Varnish, as it will need some time to cache the pages that visitors request. You can take full advantage of the platform’s capacity if the websites that are using it use also a dedicated IP address, but owing to the fact that your server includes several IP addresses by default, you won’t need to pay anything on top of your monthly charge for the machine itself.
