Varnish is a data caching platform, which is occasionally called a caching HTTP reverse proxy. It is a web application accelerator tool that can accelerate the load speed of a website by up to 1000%, based on its content. Each time a visitor opens any page on a website that uses Varnish, the platform caches the page and delivers it instead of the web server if the visitor accesses it again. Thus, the web browser request from the visitor is not processed by the server and the web page will open much faster, as Varnish can serve data many times faster than any web server software. The end result will be a substantially faster loading website, which means an enormously improved visitor experience. When any of the cached pages is updated on the live website, the information that Varnish caches in its memory is ‘refreshed’ too, so the site visitors will never see outdated info.

Varnish in Cloud Hosting

If you host your sites in a cloud hosting account with us, you will be able to activate Varnish with several mouse clicks from your Control Panel. The caching platform comes as an upgrade with all our packages and you can select the number of the websites that will use it and the maximum storage space that will be available for the cached content. The two features that can be upgraded in the Control Panel’s Upgrades section 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 plenty of memory for one large-size website or less memory for multiple smaller ones. You can unlock the full potential of the Varnish caching platform if the sites use a dedicated IP address. With the Control Panel, you can effortlessly start/reboot/terminate an instance, clear the cached data independently for each website that employs the Varnish platform or check a detailed system log file.

Varnish in Semi-dedicated Servers

The Varnish caching platform is included in the basic set of services that you’ll obtain in case you decide to host your Internet sites in a semi-dedicated server account. You can enable it for any of your Internet sites through our avant-garde Hepsia hosting Control Panel. The default amount of memory that Varnish can use to cache data is 64 MB, but if you decide that you need more, you can upgrade this memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, i.e. the number of the sites that can use this platform at the same time. Since these two things aren’t tied to each other, you can use a couple of websites with the default memory or you can order 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 get a dedicated IP address for the websites that utilize its power. The Hepsia Control Panel will provide you with an easy means of rebooting any instance. On top of that, you will be able to delete the cached contents with just a click.

Varnish in VPS Servers

The Varnish data caching platform comes by default with all VPS service offered by our company on the condition that the VPS server is ordered with the Hepsia hosting Control Panel, so you can optimize the overall performance of your sites with just a few mouse clicks. The more powerful the plan, the more system memory Varnish will have at its disposal, but even with a less powerful package, the platform will be able to utilize several hundred megabytes, so even if you have several different sites, you’ll notice a great reduction in the overall server load and a substantially faster webpage load speed. The Varnish platform will need to work for a while as the visitors navigate the pages and as soon as the site content has been cached, you will notice the effect. One of the pros of using Varnish is that a lower-end and less expensive VPS plan will accomplish the same job as a more pricey one without the caching platform, so not only will your websites work much better, but you will also save a certain amount of money.

The Varnish caching platform can be enabled and administered without efforts through Hepsia’s simple-to-navigate GUI and, with no more than one single click of the mouse, you can browse an in-depth system log, create or reboot an instance, clear the cache for any site and much, much more. Soon after you set up Varnish for a specific domain or sub-domain, it will begin caching the pages loaded by your visitors and as soon as it has cached enough content, you will observe a significantly better site performance plus a reduced load on the machine. With Varnish-dedicated memory starting at three gigabytes, you will be able to use the platform for load distribution purposes even if you run a vast number of sites on the server.
