Varnish is a website accelerator platform, which caches information for quicker access. It’s occasionally called an HTTP reverse proxy as well and it interacts between a web server and a web browser. When a visitor accesses a specific webpage, its content is requested by the browser, and then the web server handles this browser request and sends back the requested info. If Varnish is activated for a given website, it will cache the pages on the first visit and in case the visitor opens a cached page once more, the information will be delivered by the caching platform and not by the server. The increased loading speed is a result of the significantly faster response speed that the Varnish platform offers as compared to any server software. Of course, this doesn’t mean that the users will continue seeing the exact same content over and over again, since any update on any of the web pages is reflected in the content that the Varnish platform stores in its system memory.
Varnish in Hosting
You can use Varnish’s potential and accelerate the load speed of your websites regardless of the hosting plan that you’ve picked and you can add and set up the content caching platform with a few clicks through the user-friendly graphical interface offered by our avant-garde Hepsia Control Panel. During the procedure, you will be able to choose two separate things – how many websites will employ Varnish, i.e. the number of instances, and how much information will be cached, i.e. the amount of memory. The latter is available in increments of 32 megabytes and is not bound to the number of instances, so you can add more instances and less memory and vice versa. If you’ve got plenty of content on a particular Internet site and you win lots of visitors, more memory will guarantee you a better result. You may also consider using a dedicated IP for the websites that will use Varnish. Hepsia will provide you with easy 1-click buttons for switching off or restarting any instance, for deleting the cache associated with each website and for seeing detailed logs.
Varnish in Semi-dedicated Hosting
The Varnish caching platform is included in the default service set that you’ll obtain in case you decide to host your websites in a semi-dedicated server account. You can configure it for any of your sites via our leading-edge Hepsia Control Panel. The default memory that Varnish can use to cache content is 64 megabytes, 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 websites that can use this platform simultaneously. Since these two features aren’t tied to each other, you can use a few sites with the default memory or you can add 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 allocate a dedicated IP address to the sites that utilize its power. The Hepsia Control Panel will offer you a simple way of rebooting any instance. Furthermore, you will be able to clear the cached files with just one single click.
Varnish in VPS Web Hosting
You can take full advantage of the load balancing potential of Varnish with any of our VPS web hosting services when you select Hepsia as your hosting Control Panel. The content caching platform comes by default and the system memory that it will be able to utilize to cache the content of your websites is dependent on the specific VPS package that you’ve picked, but even with the less powerful packages, you will have no less than several hundred MB of memory at your disposal exclusively for content caching purposes. This amount is sufficient enough to optimize the work of multiple websites. It will take some time for you to distinguish the effects, as the Varnish platform caches the content that site visitors request, but shortly after that you’ll notice the significantly reduced load on your VPS server and the enhanced website loading speed. The Varnish caching platform will allow you to use a lower-end VPS plan for websites which would typically require a more high-priced hosting solution.
Varnish in Dedicated Servers Hosting
All dedicated hosting services that are ordered with the custom-built Hepsia hosting Control Panel feature Varnish, which is among the pre-installed software platforms that you will get with the server. The Varnish platform can be set up and administered without any effort via Hepsia’s intuitive GUI and, with no more than one click of the mouse, you can browse an in-depth log, add or reboot an instance, delete the cache associated with any Internet site and much, much more. Shortly after you set up Varnish for a particular domain or sub-domain, it will start caching the pages opened by the site visitors and as soon as it has cached enough content, you’ll observe a tremendously faster site performance and a lowered load. With Varnish-dedicated virtual memory starting at three gigabytes, you’ll be able to use the software platform for workload distribution purposes even if you host an immense number of websites on your dedicated server.
