Varnish is a data caching platform, which is sometimes referred to as an HTTP reverse proxy. It is a web accelerator tool that can improve the load speed of a site by up to 1000%, depending on its content. Every time a visitor opens any page on a site that uses Varnish, the platform caches the page and delivers it instead of the web server if the visitor accesses it again. Thus, the browser request from the visitor is not processed by the web server and the page will load much faster, as the Varnish caching platform can serve information many times faster than any web server software. The result is a considerably faster loading website, which means an improved browsing experience. If any of the cached pages is updated on the live website, the data that Varnish caches in its memory is ‘refreshed’ too, so the users will never see outdated content.

Varnish in Shared Web Hosting

In case you host your Internet sites in a shared web hosting account with us, you will be able to add Varnish with a couple of clicks of the mouse via your Control Panel. The platform comes as an optional upgrade with all our shared web hosting packages and you can choose how many websites will use it and the maximum amount of system memory that will be used 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 aren’t directly linked to each other, so you can decide whether you need plenty of memory for one single large-sized site or less memory for several smaller ones. You can unleash the full potential of the Varnish platform if the sites use a dedicated IP address. Using the hosting Control Panel, you can swiftly start/reboot/terminate an instance, delete the cached data independently for each website which employs Varnish or check an in-depth system log file.

Varnish in Semi-dedicated Hosting

The Linux semi-dedicated hosting that we offer will allow you to employ Varnish once your brand new semi-dedicated server account has been set up, as the content caching platform is available by default. 64 MB of system memory will be allocated to Varnish the second your account is activated, so you can take advantage of this load balancing software once your site has been launched. In case you are in need of more system memory, you can order 32 megabytes at a time from the Hepsia Control Panel’s Upgrades section and it will be allocated to your semi-dedicated machine in a flash. You can also increase the number of the Internet sites that use Varnish, or the so-called ‘instances’, which are not directly bound to the amount of system memory that you use, which suggests that you’ll have more freedom. The Varnish platform will seriously lower the load on the semi-dedicated server that your websites produce, so your site visitors can enjoy fast-opening pages. You’ll be able to manage Varnish without effort via the Hepsia Control Panel using quick-access buttons. You’ll be able to start/shut down any of the instances that you’ve got, to clear the cached data for any of your websites or to view system logs.

Varnish in VPS

We provide Varnish with all Hepsia-managed Linux VPS, so in case you order a server with this web hosting Control Panel, you’ll be able to make full use of the caching platform at no extra fee. Varnish can use different amounts of system memory for caching purposes based on the particular server configuration that you have selected on the order page, but at any rate, this amount won’t be less than several hundred MB. This is more than enough to boost the overall performance of several different regularly visited sites, so the better page browsing speeds and the decreased load on the server will be noticeable. The effect may not be visible right away, since the Varnish platform will require a certain amount of time to cache the site content that visitors access, but soon after you enable it, you’ll witness its full potential. This platform will allow you to use a less powerful Virtual Private Server and to pay less cash to get the exact same performance you’d get with a more powerful virtual machine without Varnish.

Varnish in Dedicated Hosting

In case you order a dedicated server with the Hepsia Control Panel, you will obtain the Varnish platform at no extra cost and you’ll exert full control over it via a really time and effort saving GUI – you’ll be able to start, to discontinue or to restart an instance, to view an in-depth system log, to clear the cache for any website and much, much more. Varnish will have several GB of virtual memory at its disposal, so even if you own traffic-hungry sites with plenty of visitors, you will notice the considerably better web page load speeds and the lowered load on the dedicated server. This will become a fact soon after you begin using the Varnish platform, as it will require a certain amount of time to cache the content that users browse. You can get the most out of the platform’s capabilities if the websites that are using it use also a dedicated IP, but due to the fact that your server comes with a few IP addresses by default, you will not have to pay anything on top of the monthly fee for the machine itself.
