Varnish is a web application accelerator platform, which caches info for quicker access. It’s occasionally called a caching HTTP reverse proxy as well and it works between a web server and its users. When a website visitor accesses a particular webpage, its content is requested by the browser, and then the server handles this request and delivers the needed content. If Varnish is activated for a certain website, it will cache its pages at the very first request and if the visitor visits a cached page once more, the data will be delivered by the accelerator platform and not by the server. The improved load speed is an end result of the much faster response speed that Varnish offers compared with any server software. Of course, this doesn’t mean that the users will keep being served the exact same content again and again, as any change on any of the web pages is reflected in the content that the Varnish platform stores in its system memory.
Varnish in Web Hosting
If you host your Internet sites under a web hosting account with our company, you’ll be able to activate Varnish with a couple of mouse clicks through your Control Panel. The caching platform is available as an optional upgrade with all our shared hosting plans and you can select the number of the sites that will use it and the maximum amount of system memory that will be available for the cached data. 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 are not directly linked to each other, so you can choose whether you need plenty of memory for a single large-size website or less memory for several smaller ones. You can unlock the full potential of Varnish if the sites use a dedicated IP. With the hosting Control Panel, you can swiftly start/reboot/disable an instance, delete the cached contents independently for each website which uses Varnish or view an in-depth system log file.
Varnish in Semi-dedicated Servers
The Linux semi-dedicated servers that we are offering will permit you to employ Varnish once your brand new semi-dedicated server account is active, as the platform comes by default. 64 MB of system memory will be assigned to Varnish the moment your account is enabled, so you can take advantage of this load distribution software once you launch your website. If you’re in need of more memory, you can add 32 megabytes at a time from the Hepsia hosting Control Panel’s Upgrades section and it will be assigned to your semi-dedicated machine in a flash. You can also increase the number of the sites that use Varnish, or the so-called ‘instances’, which are not linked directly to the amount of memory that you use, which goes to say that you’ll have more freedom. The caching platform will enormously lower the server load generated by your sites, so your website visitors can enjoy fast-loading web pages. You’ll be able to manage Varnish without effort via your Control Panel using quick-access controls. You will be able to start/stop any of the instances that you have, to clear the cached data for any of your Internet sites or to view system log files.
Varnish in VPS Servers
We offer Varnish with all Hepsia-managed Linux VPS servers, so if you purchase a VPS with this Control Panel, you’ll be able to use the content caching platform at no additional fee. The Varnish platform can use different amounts of system memory for data caching purposes depending on the specific plan that you’ve selected during the signup process, but in any case, this amount will not be less than several hundred megabytes. This is more than enough to optimize the overall performance of a handful of large-sized websites, so the better web page loading speeds and the lowered load will be perceptible. The result may not be detectable instantly, since the Varnish platform will need some time to cache the site content that people request, but soon after you set it up, you will feel its full capacity. This platform will allow you to use a lower-end VPS server and to pay less cash to get the same performance you’d get with a higher-end virtual machine without Varnish.
Varnish in Dedicated Servers
All dedicated service that are ordered with the in-house developed Hepsia web hosting Control Panel come with Varnish, which is one of the pre-installed software platforms that you will get with the dedicated server. The Varnish content caching platform can be enabled and administered with ease from Hepsia’s time and effort saving interface and, with no more than one mouse click, you can see an exhaustive log, add or restart an instance, clear the cached data associated with any Internet site and much, much more. Soon after you configure Varnish for a certain domain or sub-domain, it will start caching the web pages opened by the site visitors and as soon as it has cached enough web content, you’ll witness a significantly better website performance plus a lowered load on your dedicated machine. With Varnish-dedicated virtual memory starting at 3 gigabytes, you’ll be able to use the software platform for load distribution purposes even if you host plenty of websites on your dedicated machine.
