Varnish is a web application accelerator platform, which caches content for the sake of quicker access. It is sometimes called a caching HTTP reverse proxy as well and it interacts between a web server and a browser. When a website visitor opens a given webpage, the content is requested by the Internet browser, and then the server handles this request and sends back the requested data. If Varnish is enabled for a specific site, it will cache the pages at the first request and in case the visitor accesses a cached page once again, the information will be delivered by the caching platform instead of the server. The improved speed is a result of the much faster response time that the Varnish platform offers as compared with any web server software. At the same time, this doesn’t mean that the website visitors will continue being served the exact same content again and again, because any modification on any of the web pages is reflected in the content that Varnish caches in its memory.
Varnish in Shared Hosting
Varnish is available as an optional upgrade with all our shared plans. You can add it to your hosting account via the Hepsia hosting Control Panel, which is offered with all shared web hosting packages and you will get an exceptionally user-friendly interface, which will give you full control over the caching system. Using one-click fast-access buttons, you can reboot or disable any of the instances, i.e. Varnish will no longer be activated for a specific Internet site. You can also view a comprehensive system log file or delete the cache associated with any of the Internet sites. When you add Varnish to your shared web hosting package, you’ll be able to choose the total amount of memory that will be available to you for content caching purposes and the number of the websites that will use Varnish. You can always get more memory in increments of 32 megabytes and, for maximum performance, you can allocate a dedicated IP address to the websites that will use Varnish. This will allow you to get the most out of your websites and to have a lot of pleased visitors.
Varnish in Semi-dedicated Servers
Varnish is an essential part of the standard set of services that you will get in case you decide to host your sites in a semi-dedicated server account. You can activate it for any of your websites through our next-gen Hepsia Control Panel. The default system memory that the Varnish caching platform can use to cache content is 64 MB, but if you decide that you want more, you can upgrade this amount 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. Since these two things aren’t linked to each other, you can use a couple of instances with the default memory or you can add more memory in increments of 32 megabytes and use all of it for a single site. The Varnish platform performs best if you use a dedicated IP address for the sites that utilize its power. Hepsia will give you a simple way of restarting any instance. In addition, you will be able to clear the cached data with only one mouse click.
Varnish in Dedicated Servers
All dedicated web hosting plans that are ordered with the custom-built Hepsia website hosting Control Panel include Varnish, which is one of the pre-installed software platforms that you will get with the server. The Varnish caching platform can be set up and managed with no effort through the Hepsia Control Panel’s simple-to-work-with graphical interface and, with no more than one click of the mouse, you can view a detailed log, create or restart an instance, clear the cache associated with any website and much, much more. Shortly after you configure the Varnish platform for a certain domain or sub-domain, it will begin caching the webpages opened by the site visitors and once it has cached enough content, you’ll observe a considerably faster site performance in addition to a decreased load on the dedicated server. With Varnish-dedicated virtual memory starting at 3 gigabytes, you’ll be able to use the software platform for workload distribution purposes even if you host a huge number of sites on the dedicated server.
