Varnish is a web accelerator platform, which caches information for the sake of quicker access. It is occasionally called an HTTP reverse proxy too and it works between a web server and its users. When a visitor accesses a particular webpage, its content is requested by the browser, and then the server processes this request and delivers the needed information. If Varnish is activated for a particular site, it will cache the pages on the very first visit and if the visitor visits a cached page once more, the information will be delivered by the accelerator platform instead of the server. The increased loading speed is an end result of the much faster response time that Varnish offers compared with any web server software. Of course, this doesn’t mean that the visitors will continue being served the exact same content over and over again, as any modification on any of the pages is reflected in the content that Varnish saves in its memory.
Varnish in Cloud Web Hosting
In case you host your sites under a cloud web hosting account with us, you’ll be able to add Varnish with several mouse clicks via your Control Panel. The data caching platform is offered as an optional upgrade with all our shared 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 data. The two features that can be upgraded in the Control Panel’s Upgrades section are the amount of system memory and the number of instances and they’re not directly linked to each other, so you can choose whether you need a lot of memory for one large-scale site or less memory for several smaller ones. You can use the full potential of the Varnish caching platform if the websites use a dedicated IP address. Using the hosting Control Panel, you can effortlessly start/reboot/stop an instance, delete the cached content individually for each website that uses Varnish or check an exhaustive log.
Varnish in Semi-dedicated Hosting
All our Linux semi-dedicated services include Varnish by default, so you can make full use of the website accelerator and optimize the load speed of any site that you host on our platform. You’ll get 64 megabytes of memory exclusively for the Varnish accelerator at no extra fee and you’ll be able to create an instance with no more than a few clicks of the mouse through the Hepsia Control Panel, which is included with the semi-dedicated server packages. In case you need more memory, the latter is available in increments of 32 megabytes in the Control Panel’s Upgrades section and it will be at your disposal immediately. You can also order more instances as an upgrade, so you can decide if a lot of content will be cached for one site or if the available memory will be used by several websites. Hepsia will enable you to reboot or to remove any instance, to check the system log associated with it or to clear the cached files using 1-click buttons. To take full advantage of the Varnish accelerator, you can assign a dedicated IP to the Internet sites which will use it.
Varnish in VPS Hosting
You can take advantage of Varnish with all our virtual private server packages at no additional charge, as the data caching platform is pre-installed and is available by default. The sole prerequisite is that the virtual server must come with the Hepsia hosting Control Panel, via which you’ll be able to activate Varnish for any of your Internet sites with just a few clicks. Each package comes with a different amount of system memory for data caching purposes, but you will get minimum several hundred MB, which is quite enough even for several resource-requiring sites. Soon after you set up Varnish, it’ll start caching the content that your website visitors request, so you will notice the considerably better website loading times and the lowered load on the server very soon. The Varnish platform will allow you to use a less costly virtual server, since you will not need that much power to warrant the uninterrupted operation of your Internet sites even if you own large-sized Internet sites with a lot of visitors. Best results are accomplished if the Internet sites that use the Varnish platform also use a dedicated IP.
Varnish in Dedicated Web Hosting
In case you order a dedicated server with the Hepsia hosting Control Panel, you will get the Varnish content caching platform at no additional charge and you’ll have full control over it via a pretty simple-to-navigate GUI – you will be able to start, to remove or to reboot an instance, to view an exhaustive system log, to delete the cached files associated with any site and much more. The Varnish platform will have several gigabytes of memory at its disposal, so even if you have large-sized websites with an immense number of visitors, you’ll notice the significantly better website loading speeds and the less load on your server. This will become a fact shortly after you begin using Varnish, as it will require some time to cache the pages that people request. You can get the most out of the platform’s capabilities if the websites that are using it also use a dedicated IP, but owing to the fact that your server comes with a couple of IP addresses by default, you won’t have to pay anything on top of your monthly charge for the machine itself.
