Varnish is a web application accelerator platform, which caches information for the sake of faster access. It’s occasionally called an HTTP reverse proxy too and it interacts between a web server and a web browser. When a site visitor opens a particular page, the content is requested by the browser, and then the server handles this browser request and returns the requested info. If Varnish is activated for a specific site, it will cache the pages at the first request and in case the visitor visits a cached page once more, the information will be delivered by the accelerator platform instead of the server. The increased loading speed is an end result of the considerably faster response time that Varnish offers compared to any web server software. Of course, this does not mean that the website visitors will continue being served the same content again and again, since any update on any of the pages is reflected in the content that the Varnish platform caches in its memory.
Varnish in Shared Hosting
You can take advantage of Varnish’s potential and increase your websites’ loading speed irrespective of the shared hosting package that you have chosen and you can activate and configure the content caching platform with several clicks of the mouse via the simple-to-work-with interface offered by our leading-edge Hepsia Control Panel. During the process, you will be able to select two separate things – how many sites will employ the Varnish caching platform, 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 linked to the number of instances, so you can use more instances with less memory and the other way around. If you’ve got plenty of content on a given site and you get numerous visitors, more system memory will give you better results. You may also consider employing a dedicated IP for the Internet sites that will use the Varnish caching platform. Hepsia will provide you with easy one-click controls for removing or restarting any instance, for deleting the cache associated with any website and for viewing elaborate system logs.
Varnish in Semi-dedicated Servers
The Varnish caching platform is an essential part of the default set of services that you will get in case you choose to host your Internet sites under a semi-dedicated server account. You can enable it for any of your sites via our next-gen Hepsia Control Panel. The default system memory that the Varnish platform can use to cache data is 64 megabytes, but if you decide that you want more, you can upgrade this amount from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, i.e. the number of the sites that can use this caching platform simultaneously. As these two things 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 megabytes and use all of it for one single website. Varnish works best when you allocate a dedicated IP address to the sites that utilize its power. The Hepsia Control Panel will provide you with an easy means of restarting any instance. In addition, you’ll be able to clear the cached contents with only one click.
Varnish in VPS Servers
The Varnish data caching platform comes by default with each of the VPS plans offered by our company as long as the machine is ordered with the Hepsia Control Panel, so you can enhance the performance of your websites with only a couple of clicks. The more powerful the plan, the more memory Varnish will have at its disposal, but even with a lower-end package, the platform will be able to utilize several hundred megabytes, so even if you manage a handful of websites, you will notice a substantial decrease in the overall server load and a substantially better webpage loading speed. The Varnish caching platform will have to work for a while while the visitors browse the site and once the content has been cached, you’ll notice the results. One of the benefits of using Varnish is that a less powerful and less expensive VPS package will do the same job as a more costly one without the platform, so not only will your Internet sites work much better, but you’ll also save a certain amount of money.
Varnish in Dedicated Servers
All dedicated web hosting plans which are ordered with the tailor-made Hepsia hosting Control Panel feature Varnish, which is one of the pre-installed software platforms that you will get with the machine. The Varnish caching platform can be set up and administered without any effort from the Hepsia Control Panel’s simple-to-use GUI and, with no more than one single click, you can view a comprehensive system log, add or reboot an instance, clear the cached data associated with any website and much more. Shortly after you configure Varnish for a certain domain or sub-domain, it will start caching the web pages accessed by your site visitors and as soon as it has cached enough content, you will witness a tremendously faster website performance as well as a reduced load. With Varnish-dedicated virtual memory starting at 3 gigabytes, you will be able to use the platform for load balancing purposes even if you host a vast number of sites on the dedicated machine.
