Varnish is a web app accelerator platform, which caches info for the sake of faster response times. It is occasionally called a caching HTTP reverse proxy too and it interacts between a web server and its users. When a website visitor loads a given webpage, the content is requested by the web browser, and then the server processes this browser request and returns the necessary data. If Varnish is activated for a specific website, it will cache the pages on the very first visit and in case the user visits a cached page once more, the data will be delivered by the accelerator platform and not by the server. The increased loading speed is a result of the substantially faster response time that the Varnish platform offers compared to any web server software. At the same time, this doesn’t mean that the visitors will keep seeing the same content over and over again, because any change on any of the web pages is reflected in the content that the Varnish platform saves in its memory.

Varnish in Shared Hosting

If you host your Internet sites in a shared hosting account with our company, you’ll be able to add Varnish with a couple of clicks via your Control Panel. The platform is available as an optional upgrade with all our web hosting plans and you can choose the number of the websites that will use it and the maximum amount of system memory that will be available for the cached data. The two features that can be upgraded in the Upgrades section of the Control Panel are the amount of memory and the number of instances and they aren’t linked directly to each other, so you can decide whether you need lots of memory for a single large-sized site or less memory for multiple smaller ones. You can make use of the full potential of the Varnish caching platform in case the websites use a dedicated IP address. With the Control Panel, you can easily start/restart/disable an instance, clear the cached content individually for each site which employs the Varnish platform or view an elaborate log file.

Varnish in Semi-dedicated Servers

The Varnish platform is part of the default service set that you’ll acquire in case you decide to host your websites under a semi-dedicated server account. You can set it up for any of your sites via our avant-garde Hepsia Control Panel. The default amount of system memory that Varnish can use to cache content is 64 megabytes, but if you decide that you need more, you can upgrade this amount from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, in other words – the number of the sites that can use this caching platform at the same time. Since these two things aren’t linked to each other, you can use several websites with the default memory or you can get more memory in increments of 32 MB and use all of it for one single web site. The Varnish caching platform performs best if you allocate a dedicated IP address to the sites that utilize its power. Hepsia will offer you an easy means of rebooting any instance. In addition, you’ll be able to delete the cached data with only one click.

Varnish in VPS Servers

The Varnish content caching platform is included by default with all VPS web hosting service that we’re offering as long as the virtual machine is ordered with the Hepsia Control Panel, so you can enhance the performance of your sites with just 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 lower-end plan, the platform will be able to utilize several hundred megabytes, so even if you have several Internet sites, you will notice a significant reduction in the overall server load and a much faster page load speed. The platform will need to work for a while while the visitors navigate the pages and once the content has been cached, you’ll see the result. One of the pros of employing Varnish is that a less powerful and less costly package will do the exact same job as a more pricey one without the platform, so not only will your Internet sites work significantly better, but you will also save a certain amount of cash.

Varnish in Dedicated Servers

All dedicated servers 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’ll get with the dedicated server. The Varnish content caching platform can be configured and administered with ease via Hepsia’s time and effort saving graphical interface and, with no more than one single click of the mouse, you can see a detailed log, create or restart an instance, clear the cached files associated with any Internet site and much more. Shortly after you activate the Varnish platform for a certain domain or subdomain, it will begin caching the pages opened by your visitors and once it has cached enough web content, you’ll perceive a significantly faster site performance and a lowered server load. With Varnish-dedicated memory starting at 3 GB, you’ll be able to use the platform for load distribution purposes even if you run lots of sites on the dedicated machine.
