Varnish is a web app accelerator platform, which caches data for the sake of faster access. It’s occasionally referred to as an HTTP reverse proxy as well and it works between a web server and an Internet browser. When a visitor loads a particular webpage, its content is requested by the browser, and then the web server handles this request and delivers the necessary info. If Varnish is enabled for a specific site, it will cache its pages at the first request and in case the visitor opens a cached page for a second time, the info will be delivered by the caching platform and not by the web server. The accelerated speed is a result of the substantially faster response time that Varnish offers as compared with any server software. At the same time, this does not mean that the users will keep seeing the very same content again and again, because any change on any of the web pages is reflected in the content that Varnish keeps in its memory.

Varnish in Cloud Hosting

If you host your sites under a cloud hosting account with our company, you’ll be able to add Varnish with a few clicks through your hosting Control Panel. The platform comes as an upgrade with all our shared hosting packages and you can select the number of the sites that will use it and the maximum amount of system memory that will be used for the cached content. The two features that can be upgraded in the Control Panel’s Upgrades section are the number of instances and the amount of memory and they’re not tied directly to each other, so you can choose if 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 platform in case the websites use a dedicated IP. With the hosting Control Panel, you can easily start/restart/remove an instance, delete the cached contents individually for each site that employs the Varnish platform or check a comprehensive system log file.

Varnish in Semi-dedicated Hosting

The Linux semi-dedicated hosting offered by our company will allow you to employ Varnish once your brand new account has been created, since the data caching platform comes by default. 64 MB of system memory will be assigned to Varnish the second your account is activated, so you can use this workload balancing software as soon as your site has been launched. If you need more system memory, you can add 32 MB at a time from the Upgrades section of the Hepsia Control Panel and it will be assigned to your semi-dedicated machine straight away. You can also increase the number of the Internet sites that use Varnish, or the so-called ‘instances’, which are not bound directly to the amount of system memory that you use, which suggests that you will have more flexibility. The platform will substantially lower the server load that your sites cause, so your website visitors can enjoy fast-loading web pages. You will be able to manage the Varnish platform with no effort via your Hepsia Control Panel using quick-access controls. You will be able to start/delete any of the instances that you’ve got, to clear the cached data associated with any of your Internet sites or to see system logs.

Varnish in Dedicated Web Hosting

If you order a dedicated server with the Hepsia Control Panel, you will acquire the Varnish platform at no additional fee and you’ll exert full control over it through an amazingly simple-to-work-with graphical interface – you will be able to start, to discontinue or to reboot an instance, to view a comprehensive system log, to delete the cache associated with any website and much, much more. The Varnish caching platform will have several gigabytes of memory at its disposal, so even if you host resource-intensive Internet sites with a vast number of visitors, you’ll notice the significantly better website load speeds and the lowered load on your server. This will become a fact soon after you begin using Varnish, since it will need some time to cache the site content that users request. You can get the most out of the platform’s capacity in case the Internet sites that are using it also use a dedicated IP, but due to the fact that your dedicated server comes with a few IP addresses by default, you won’t have to pay anything on top of your monthly charge for the machine itself.
