Varnish is a web accelerator platform, which caches info for faster access. It’s sometimes called a caching HTTP reverse proxy too and it works between a web server and a web browser. When a website visitor loads a particular webpage, the content is requested by the browser, and then the web server processes this request and sends back the needed data. If Varnish is enabled for a particular site, it will cache the pages at the first request and if the visitor accesses a cached page for a second time, the information will be delivered by the caching platform and not by the web server. The accelerated speed is an end result of the considerably faster response time that the Varnish platform offers as compared with any web server software. Of course, this does not mean that the visitors will continue being served the very same content over and over again, because any change on any of the pages is reflected in the content that the Varnish platform keeps in its memory.

Varnish in Website Hosting

In case you host your websites in a website hosting account with us, you’ll be able to activate Varnish with a few mouse clicks through your hosting Control Panel. The platform is available as an upgrade with all our hosting packages and you can select how many sites will use it and the maximum amount of system memory that will be used for the cached content. The two features that can be upgraded in the Upgrades section of the Control Panel are the number of instances and the amount of memory and they’re not directly tied to each other, so you can decide whether you want plenty of memory for one single large-scale site or less memory for multiple smaller ones. You can unleash the full potential of Varnish in case the websites use a dedicated IP address. Using the hosting Control Panel, you can easily start/reboot/shut down an instance, delete the cached contents independently for each website which employs the Varnish platform or view a detailed log file.

Varnish in Semi-dedicated Servers

Varnish is a feature, which is offered as standard with all semi-dedicated servers offered by us and you can use it for load balancing purposes. It’s available in your Hepsia Control Panel. The Varnish platform comes with 64 MB of system memory for cached content storing purposes and you can use it with any Internet site that you host in your semi-dedicated account. If you’re in need of more than that, you can increase the memory allocation. The memory itself is offered in increments of 32 megabytes in the Control Panel’s Upgrades section. The very same section will permit you to activate more instances too, in case you would like to use the Varnish caching platform with more websites. The two upgrades can be ordered separately – you can cache the content of a single traffic-consuming Internet site or run a number of sites with the default memory quota. You can take full advantage of the Varnish caching platform if you have a dedicated IP and you can order one with your semi-dedicated plan as well. Hepsia will give you complete control over the platform and, with no more than one mouse click, you will be able to delete the cached content, to see a log or to reboot an instance.

Varnish in VPS Servers

You can use Varnish with any of our VPS server plans at no extra cost, since the data caching platform is pre-installed and is included by default. The one and only prerequisite is that the virtual machine must come with the Hepsia Control Panel, through which you will be able to activate Varnish for any of your sites with just a couple of mouse clicks. Each VPS package includes a different amount of system memory for content caching purposes, but you will get at least several hundred MB, which is quite sufficient even for multiple traffic-heavy Internet sites. Soon after you set up Varnish, it will begin caching the content that your site visitors open, so you will notice the tremendously faster Internet site load times and the lowered load on the VPS in no time. The Varnish caching platform will allow you to use a less pricey VPS server, as you will not need that many resources to guarantee the correct operation of your Internet sites even if you run large-scale Internet sites with a lot of visitors. Best results are accomplished if the websites that use the Varnish caching platform use also a dedicated IP address.

Varnish in Dedicated Servers

All dedicated servers that are ordered with the custom Hepsia hosting Control Panel include Varnish, which is one of the pre-installed platforms that you will get with the server. The Varnish caching platform can be set up and managed without any effort via Hepsia’s simple-to-use interface and, with no more than one single mouse click, you can browse an elaborate log, add or reboot an instance, delete the cached content for any Internet site and much, much more. Soon after you set up the Varnish platform for a certain domain or sub-domain, it will begin caching the webpages opened by your visitors and as soon as it has cached enough content, you’ll witness a substantially better website performance and a reduced load on the machine. With Varnish-dedicated virtual memory starting at 3 gigabytes, you will be able to use the platform for workload balancing purposes even if you run a vast number of websites on your machine.
