Varnish is a website accelerator platform, which caches content for the sake of quicker response times. It’s occasionally called a caching HTTP reverse proxy too and it works between a web server and a web browser. When a site visitor accesses a particular web page, the content is requested by the Internet browser, and then the web server processes this browser request and sends back the needed data. If Varnish is enabled for a certain site, it will cache its pages on the very first request and if the user accesses a cached page for a second time, the content will be delivered by the accelerator platform and not by the server. The improved load speed is a result of the much faster response speed that the Varnish platform offers compared with any web server software. Of course, this does not mean that the users will keep being served the very same content again and again, since any change on any of the web pages is reflected in the content that Varnish caches in its memory.

Varnish in Cloud Web Hosting

If you host your Internet sites under a cloud web hosting account with us, you’ll be able to add Varnish with a few mouse clicks via your Control Panel. The caching platform is offered as an optional upgrade with all our shared hosting packages 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 upgradeable features in the Upgrades section of the Control Panel are the number of instances and the amount of memory and they’re not directly tied to each other, so you can choose if you need plenty of memory for one single large site or less memory for several smaller ones. You can use the full potential of the Varnish platform if the websites use a dedicated IP address. Using the Control Panel, you can quickly start/reboot/stop an instance, clear the cached contents individually for each website that uses the Varnish platform or check an in-depth log.

Varnish in Semi-dedicated Hosting

The Varnish content caching platform is part of the standard set of services that you will get if you decide to host your websites in a semi-dedicated server account. You can activate it for any of your sites through our next-generation Hepsia hosting Control Panel. The default amount of memory that the Varnish platform can use to cache content is 64 megabytes, but if you decide that you need more, you can upgrade this memory 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 platform simultaneously. Since these two things are not linked to each other, you can use a couple of instances with the default memory or you can get more memory in increments of 32 megabytes and use all of it for a single Internet site. The Varnish platform works best when you use a dedicated IP address for the sites that utilize its power. The Hepsia Control Panel will offer you an easy means of restarting any instance. Furthermore, you will be able to clear the cached files with only one single mouse click.

Varnish in VPS

You can use the load balancing potential of Varnish with each of our Linux VPS services when you select Hepsia as your hosting Control Panel. The content caching platform is available by default and the amount of system memory that it will be able to utilize to cache your website content is dependent upon the given Virtual Private Server package that you’ve selected, but even with the less powerful plans, you’ll have no less than several hundred MB of system memory at your disposal only for caching purposes. This amount is enough to optimize the overall performance of multiple websites. It will take some time for you to see the results, as Varnish caches the content that visitors access, but shortly thereafter you will notice the significantly lowered load on the machine and the accelerated Internet site loading speed. The Varnish platform will permit you to make use of a less powerful VPS plan for websites that would typically need a more costly hosting solution.

Varnish in Dedicated Hosting

You can employ Varnish to optimize the load speed of any site that is hosted on a dedicated server with us if the Hepsia hosting Control Panel is pre-installed on it. Not only will you get the data caching platform ready to be used at no extra cost, but you will also exert full control over it through the Hepsia Control Panel’s easy-to-navigate GUI. It will take just one click to start or delete an instance or to clear the cached content associated with any website that is using the Varnish platform and if you’re more experienced, you can also see the platform’s logs. Varnish comes with no less than 3 GB of virtual memory for website content caching purposes, so even if you host a large number of sites on your server and they all use the Varnish platform, the difference in their performance will be obvious. You will just have to wait for a little while till Varnish caches whatever webpages the visitors browse on their end. The platform works best when the sites use a dedicated IP, but due to the fact that our servers come with 3 free IP addresses, you’ll have everything you need.
