Varnish is a web application accelerator, which has been gaining a lot of popularity in recent years, because it can increase the speed of any Internet site, sometimes even by 100 percent, based on the content. This tool is sometimes called an HTTP reverse proxy as well and is used to reduce the overall server load and to boost the access speed for the site visitors. Anytime a visitor opens a page on a particular website, the web browser request is handled by the web server and the requested content is served as a response. If the Varnish accelerator is enabled, it caches the pages that the site visitor opens and if any of them is accessed again, it is fetched by Varnish and not by the web server directly. The increase in the overall performance is due to the fact that the accelerator handles the browser requests tremendously faster than any web server, which leads to much faster browsing speeds for the website visitors. In case any content is updated meanwhile, the cached web pages will also be ‘refreshed’ the next time someone attempts to access them.

Varnish in Web Hosting

You can take advantage of Varnish’s full potential and boost your sites’ loading speed regardless of the web hosting package that you’ve picked and you can enable and set up the platform with a few mouse clicks from the intuitive interface offered by our next-generation Hepsia hosting Control Panel. During the process, you’ll be able to choose two separate things – how many sites will employ Varnish, i.e. the number of instances, and how much info will be cached, in other words – the amount of memory. The latter is offered in increments of 32 MB and is not tied to the number of instances, so you can order more instances with less memory and vice versa. In case you have lots of content on a specific Internet site and you receive lots of website visitors, more memory will give you a better result. You may also consider using a dedicated IP for the Internet sites that will use the Varnish platform. Hepsia will offer you easy one-click controls for switching off or restarting any instance, for deleting the cache for each website and for seeing in-depth logs.

Varnish in Semi-dedicated Hosting

The Varnish content caching platform is part of the standard set of services that you will get when you choose to host your sites under a semi-dedicated server account. You can enable it for any of your sites via our next-gen Hepsia hosting Control Panel. The default amount of system memory that the Varnish caching platform can use to cache data is 64 MB, but if you decide that you want 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 Internet sites that can use this caching platform at the same time. As these two things aren’t bound to each other, you can use a few websites with the default memory or you can add more memory in increments of 32 MB and use all of it for a single Internet site. The Varnish caching platform performs best if you set a dedicated IP for the websites that utilize its power. The Hepsia Control Panel will offer you an easy way of rebooting any instance. Also, you’ll be able to delete the cached data with just one single click.

Varnish in VPS Web Hosting

You can use the workload balancing potential of Varnish with any of our Linux VPS web hosting packages if you select Hepsia as your web hosting Control Panel. The Varnish caching platform is available by default and the amount of memory that it’ll be able to use to cache your website content depends on the given VPS plan that you’ve picked, but even with the lower-end plans, you’ll have no less than several hundred megabytes of system memory at your disposal exclusively for data caching purposes. This amount is enough to optimize the overall performance of numerous sites. It’ll take some time for you to detect the effects, since Varnish caches the content that site visitors access, but after that you’ll notice the substantially reduced load on the virtual machine and the accelerated website load speed. The Varnish platform will permit you to make use of a less powerful VPS package for Internet sites that would normally require a more costly hosting service.

Varnish in Dedicated Servers Hosting

If you order a dedicated server with the Hepsia Control Panel, you will obtain the Varnish content caching platform at no additional fee and you will have full control over it via a rather easy-to-use GUI – you will be able to start, to terminate or to restart an instance, to browse a detailed log, to clear the cached content for any website and much more. Varnish will have several gigabytes of virtual memory at its disposal, so even if you host popular sites with a huge number of visitors, you’ll notice the considerably better web page load times and the less load on your dedicated server. This will become a fact soon after you start using Varnish, since it will need some time to cache the website content that users access. You can make the most of the platform’s potential if the websites that are using it use also a dedicated IP, but considering the fact that your dedicated server comes with a couple of IP addresses by default, you won’t need to pay anything on top of your monthly fee for the machine itself.
