Learn just what Varnish is. Discover much more about web accelerators and their purpose.
Varnish is a web application accelerator platform, which caches data for the sake of quicker access. It is sometimes referred to as an HTTP reverse proxy too and it interacts between a web server and an Internet browser. When a website visitor loads a given page, the content is requested by the browser, and then the web server handles this request and sends back the needed info. If Varnish is activated for a given website, it will cache the pages at the very first request and if the visitor opens a cached page again, the info will be delivered by the accelerator platform instead of the server. The increased speed is a result of the substantially faster response speed that the Varnish platform offers compared to any server software. Of course, this doesn’t mean that the users will keep being served the same content again and again, because any change on any of the pages is reflected in the content that the Varnish platform keeps in its system memory.
Varnish in Hosting
If you host your Internet sites under a hosting
account with us, you will be able to add Varnish with a few mouse clicks from your hosting Control Panel. The caching platform comes as an upgrade with all our shared hosting packages and you can select how many sites will use it and the total 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 system memory and they are not directly tied to each other, so you can choose whether you need plenty of memory for one large-sized site or less memory for several smaller ones. You can unlock the full potential of the Varnish caching platform in case the sites use a dedicated IP address. With the hosting Control Panel, you can effortlessly start/reboot/remove an instance, clear the cached files individually for each site which uses the Varnish platform or check an exhaustive system log file.
Varnish in Semi-dedicated Hosting
The semi-dedicated services
that we offer will allow you to use Varnish once your 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 second your account is enabled, so you can take advantage of this workload distribution software as soon as your website has been published on the Internet. In case you’re in need of more system memory, you can order 32 megabytes at a time from the Hepsia hosting Control Panel’s Upgrades section and it will be allocated to your semi-dedicated server straight away. You can also increase the number of the Internet sites that use Varnish, or the so-called ‘instances’, which are not linked directly to the amount of memory that you use, which suggests that you’ll have more flexibility. The Varnish platform will significantly decrease the load that your sites produce, so your site visitors can enjoy fast-loading pages. You’ll be able to manage the Varnish caching platform with no effort through your Hepsia Control Panel using fast-access controls. You’ll be able to start/terminate any of the instances that you’ve got, to clear the cached data associated with any of your sites or to check system logs.
Varnish in VPS Hosting
We offer Varnish with all Hepsia-equipped Linux VPS hosting services
, so if you buy a server with this web hosting Control Panel, you will be able to take full advantage of the caching platform at no extra charge. The Varnish platform can use different amounts of system memory for data caching purposes depending on the specific configuration that you have chosen during the registration process, but in any case, this amount will not be less than several hundred MB. This is quite enough to improve the overall performance of a handful of traffic-heavy Internet sites, so the faster web page load speeds and the less load on your server will be perceptible. The effect may not be observable momentarily, as Varnish will need some time to cache the website content that users request, but shortly after you enable it, you will feel its full capacity. This platform will permit you to use a lower-end VPS and to give less money to get the same performance you’d get with a more powerful machine without Varnish.
Varnish in Dedicated Web Hosting
In case you order a dedicated server
with the Hepsia Control Panel, you will get Varnish at no extra fee and you will exert complete control over it via an exceptionally easy-to-use graphical interface – you will be able to start, to cancel or to reboot an instance, to check an in-depth log, to delete the cached data associated with any website and much more. Varnish will have several gigabytes of virtual memory at its disposal, so even if you run traffic-consuming websites with many visitors, you’ll notice the significantly faster site loading speeds and the lowered load. This will happen soon after you start using the Varnish platform, as it will need some time to cache the website content that users request. You can take full advantage of the platform’s potential if the sites that are using it use also a dedicated IP address, but owing to the fact that your server comes with several IPs by default, you won’t have to pay anything on top of your monthly charge for the server itself.
