Varnish is a web accelerator platform, which caches content for the sake of faster response times. It is sometimes referred to as an HTTP reverse proxy as well and it interacts between a web server and an Internet browser. When a site visitor accesses a given webpage, the content is requested by the web browser, and then the web server handles this browser request and delivers the necessary information. If Varnish is activated for a website, it will cache the pages on the very first visit and in case the visitor visits a cached page once more, the content will be delivered by the accelerator platform instead of the web server. The boosted speed is an end result of the substantially faster response time that the Varnish platform offers compared with any web server software. At the same time, this does not mean that the site visitors will continue being served the exact same content again and again, since any update on any of the web pages is reflected in the content that the Varnish platform caches in its system memory.
Varnish in Website Hosting
If you host your Internet sites under a website hosting account with our company, you’ll be able to activate Varnish with several mouse clicks via your hosting Control Panel. The content caching platform is offered as an optional upgrade with all our hosting packages and you can select the number of the sites that will use it and the total amount of system memory that will be available for the cached data. The two upgradeable features in the Upgrades section of the Control Panel are the amount of system memory and the number of instances and they aren’t directly linked to each other, so you can choose whether you need plenty of memory for one single large-scale site or less memory for multiple smaller ones. You can make use of the full potential of the Varnish caching platform if the websites use a dedicated IP. Using the Control Panel, you can quickly start/reboot/deactivate an instance, clear the cached content independently for each site that employs Varnish or check an in-depth log.
Varnish in Semi-dedicated Hosting
All our semi-dedicated hosting include Varnish by default, so you can use the web accelerator tool and accelerate the loading speed of any site that you host on our platform. You will get 64 megabytes of system memory exclusively for the Varnish accelerator at no additional fee and you will be able to enable an instance with no more than a few clicks of the mouse from the Hepsia Control Panel, which comes with the semi-dedicated server plans. If you want more memory, the latter is offered in increments of 32 megabytes in the Upgrades section of the Control Panel and it will be available to you instantly. You can also add more instances as a separate upgrade, so you can choose whether plenty of content will be cached for a single site or whether the memory will be used by multiple sites. Hepsia will enable you to reboot or to stop any instance, to view the system log file for it or to clear the cached files using one-click controls. To take full advantage of Varnish, you can assign a dedicated IP address to the sites that will employ it.
Varnish in VPS
The Varnish caching platform comes by default with each of the Linux VPS services offered by our company on the condition that the virtual server is ordered with the Hepsia hosting Control Panel, so you can improve the overall performance of your sites with just a couple of clicks of the mouse. The more powerful the package, the more system memory Varnish will have at its disposal, but even with a lower-end plan, the caching platform will be able to utilize several hundred MB, so even if you run a number of websites, you’ll notice a significant decrease in the server load and a tremendously faster site loading speed. The platform will need to work for a while while the visitors navigate the pages and once the site content has been cached, you will perceive the result. One of the advantages of employing Varnish is that a lower-end and less expensive Virtual Private Server package will do the very same job as a more pricey one without the platform, so not only will your sites perform considerably better, but you will also spare some cash.
Varnish in Dedicated Hosting
All dedicated hosting which are ordered with the custom-developed Hepsia hosting Control Panel come with Varnish, which is among the pre-installed software platforms that you will get with the machine. The Varnish content caching platform can be set up and managed without efforts through the Hepsia Control Panel’s simple-to-work-with interface and, with no more than one single mouse click, you can browse a detailed system log, create or reboot an instance, clear the cached files associated with any website and much more. Shortly after you activate the Varnish platform for a certain domain or subdomain, it will begin caching the webpages requested by your website visitors and as soon as it has cached enough web content, you will perceive a tremendously faster site performance as well as a reduced load on the machine. With Varnish-dedicated system memory starting at 3 gigabytes, you will be able to use the software platform for workload distribution purposes even if you host a vast number of Internet sites on your server.
