Varnish is a web application accelerator platform, which caches data for the sake of quicker response times. It is sometimes referred to as a caching HTTP reverse proxy as well and it works between a web server and a web browser. When a website visitor opens a particular web page, its content is requested by the web browser, and then the web server processes this request and returns the needed data. If Varnish is enabled for a particular website, it will cache its pages on the very first visit and in case the user accesses a cached page again, the content will be delivered by the caching platform instead of the web server. The accelerated speed is an end result of the significantly faster response time that the Varnish platform offers as compared with any web server software. At the same time, this does not mean that the users will continue being served the exact same content again and again, as any modification on any of the pages is reflected in the content that Varnish caches in its memory.
Varnish in Web Hosting
We offer Varnish as an optional upgrade with each and every Linux web hosting and if you’d like to use it, you can add it to your web hosting account through the Upgrades menu in your Hepsia Control Panel. There are two separate things that can be upgraded – the instances and the memory. The first one depends on the number of the Internet sites that you want to use Varnish for and the second one, which is available in increments of 32 MB, pertains to the total amount of data that the platform can store at any given time. Hepsia’s user-friendly graphical interface will enable you to terminate or to restart any instance, to see comprehensive logs or to delete the platform’s cache with just click of the mouse. For optimum results, you can use a dedicated IP for the websites that will use the caching platform. With Varnish, your site will open tremendously faster, meaning more satisfied website users and prospective clients.
Varnish in Semi-dedicated Servers
The Linux semi-dedicated hosting plans that we offer will allow you to use Varnish once your brand-new semi-dedicated server account has been activated, since the platform is offered by default. 64 MB of system memory will be allocated to Varnish the moment your account is activated, so you can make use of this load distribution software once your website has been built. In case you need more system memory, you can order 32 MB at a time from the Hepsia Control Panel’s Upgrades section and it will be assigned to your semi-dedicated server instantly. You can also increase the number of the sites that use Varnish, or the so-called ‘instances’, which are not directly tied to the amount of system memory that you use, which goes to say that you’ll have more freedom. The Varnish caching platform will immensely decrease the server load that your sites produce, so your site visitors can enjoy fast-opening web pages. You’ll be able to manage the Varnish caching platform with no effort via the Hepsia Control Panel using quick-access buttons. You’ll be able to start/disable any of the instances that you have, to clear the cache associated with any of your Internet sites or to check system logs.
Varnish in VPS Servers
We provide Varnish with all Hepsia-managed VPS hosting plans, so if you get a VPS with this hosting Control Panel, you’ll be able to take advantage of the caching platform at no additional fee. Varnish can use different amounts of system memory for content caching purposes based on the particular setup that you’ve selected on the order page, but at any rate, this amount won’t be less than several hundred MB. This is quite enough to enhance the work of several large-sized sites, so the better site loading speeds and the less load on your virtual server will be perceivable. The effect may not be detectable immediately, as Varnish will need some time to cache the website content that visitors open, but shortly after you activate it, you will witness its full potential. This caching platform will allow you to use a less powerful VPS and to pay less cash to get the very same performance you would get with a more powerful machine without Varnish.
Varnish in Dedicated Servers
All Linux dedicated servers that are ordered with the custom-built Hepsia website hosting Control Panel come with Varnish, which is one of the pre-installed software platforms that you’ll get with the server. The Varnish platform can be configured and administered without effort through the Hepsia Control Panel’s easy-to-work-with interface and, with no more than one click, you can check an exhaustive log, create or restart an instance, delete the cached files for any Internet site and much more. Shortly after you activate the Varnish platform for a specific domain or subdomain, it will begin caching the pages browsed by the site visitors and once it has cached enough web content, you will observe a substantially faster site performance plus a lowered load. With Varnish-dedicated system memory starting at 3 gigabytes, you will be able to use the software platform for load distribution purposes even if you run a large number of websites on your dedicated server.
