Learn just what Varnish is. Discover much more about web accelerators and their goal.
Varnish is a web application accelerator, which has been gaining a lot of popularity in recent years, as it can increase the loading speed of any site, sometimes even by one hundred percent, based on the content. This tool is sometimes referred to as a caching HTTP reverse proxy as well and is used to decrease the overall load on the physical server and to increase the access speed for the site visitors. Every time a visitor opens a page on a specific Internet site, the browser request is taken care of by the web server and the requested info is delivered as a response. If Varnish is activated, it caches the web pages that the site visitor opens and in case any of them is loaded again, it is fetched by Varnish and not by the web server directly. The increase in the overall performance is due to the fact that the accelerator processes the browser requests tremendously quicker than any web server, which results in much faster browsing speeds for the users. In case any data is edited meanwhile, the cached pages will also be ‘refreshed’ the next time somebody tries to access them.
Varnish in Website Hosting
Varnish is available as an optional upgrade with each and every Linux website hosting package
and if you’d like to use it, you can add it to your shared hosting account using the Upgrades section in your Hepsia Control Panel. There’re two different things that can be upgraded – the instances and the memory. The first one pertains to the number of the sites that you’d like to employ Varnish for and the second one, which comes in increments of 32 megabytes, pertains to the maximum amount of content that the platform can cache at any particular moment. Hepsia’s simple-to-use GUI will permit you to switch off or to reboot any instance, to see comprehensive logs or to delete the platform’s cache with just a click. For optimum results, you can employ a dedicated IP for the Internet sites that will use the platform. With Varnish, your site will open much faster, meaning more pleased visitors and prospective clients.
Varnish in Semi-dedicated Hosting
The Linux semi-dedicated packages
that we’re offering will allow you to employ Varnish as soon as your new semi-dedicated account has been opened, since the caching platform is offered by default. 64 MB of system memory will be allocated to Varnish the moment your account is enabled, so you can use this load balancing software as soon as your site has been published to the web. In case you’re in need of more memory, you can order 32 MB at a time from the Hepsia hosting Control Panel’s Upgrades section and it will be allocated to your semi-dedicated machine right away. You can also increase the number of the sites that use Varnish, or the so-called ‘instances’, which are not directly bound to the amount of memory that you use, which means that you will enjoy more flexibility. The caching platform will significantly decrease the load that your websites cause, so your website visitors can enjoy fast-opening web pages. You will be able to manage Varnish without effort via the Control Panel using quick-access controls. You will be able to start/delete any of the instances that you’ve got, to delete the cache for any of your Internet sites or to view system log files.
Varnish in Dedicated Servers Hosting
All Linux dedicated servers hosting packages
which are ordered with the custom-developed Hepsia web hosting Control Panel come with Varnish, which is among the pre-installed platforms that you will get with the server. The Varnish data caching platform can be set up and managed without any effort through the Hepsia Control Panel’s simple-to-navigate GUI and, with no more than one click, you can view a detailed log, add or restart an instance, clear the cached files associated with any Internet site and much more. Shortly after you set up the Varnish platform for a certain domain or subdomain, it will start caching the web pages requested by your visitors and once it has cached enough web content, you’ll observe a considerably faster website performance plus a reduced load on the dedicated machine. With Varnish-dedicated virtual memory starting at 3 GB, you will be able to use the platform for load distribution purposes even if you run plenty of Internet sites on your server.
