Varnish is a web application accelerator platform, which caches data for the sake of quicker response times. It’s sometimes called a caching HTTP reverse proxy as well and it works between a web server and a browser. When a website visitor accesses a given webpage, the content is requested by the Internet browser, and then the server processes this request and sends back the required information. If Varnish is activated for a certain website, it will cache its pages at the very first visit and if the user visits a cached page once more, the info will be delivered by the caching platform instead of the server. The increased speed is an end result of the significantly faster response time that the Varnish platform offers compared with any server software. Of course, this doesn’t mean that the site visitors will keep being served the exact same content again and again, because any modification on any of the pages is reflected in the content that Varnish keeps in its system memory.

Varnish in Website Hosting

If you host your Internet sites under a website hosting account with us, you’ll be able to activate Varnish with a few mouse clicks from your hosting Control Panel. The platform is available as an optional upgrade with all our hosting plans and you can choose how many websites will use it and the total amount of system memory that will be available for the cached content. The two upgradeable features in the Upgrades section of the Control Panel are the number of instances and the amount of memory and they are not tied directly to each other, so you can decide whether you need a lot of memory for a single large website or less memory for multiple smaller ones. You can unlock the full potential of the Varnish platform in case the sites use a dedicated IP. With the Control Panel, you can swiftly start/restart/terminate an instance, clear the cached contents independently for each website that uses the Varnish platform or check an exhaustive system log file.

Varnish in Semi-dedicated Servers

Varnish is a feature, which is included by default with all semi-dedicated servers offered by us and you can use it for load balancing purposes. It’s available in your Hepsia hosting Control Panel. The Varnish data caching platform comes with 64 megabytes of system memory for cached data storing purposes and you can employ it with any website that you host in the semi-dedicated account. In case you need more than that, you can increase the memory allocation. The memory itself is offered in increments of 32 megabytes through the Control Panel’s Upgrades section. The exact same Upgrades section will permit you to create more instances too, if you would like to use the Varnish platform with multiple sites. The two things can be added independently – you can cache the content of one resource-consuming Internet site or use several websites with the default memory quota. You can take full advantage of the Varnish caching platform if you use a dedicated IP and you can order one with your semi-dedicated server package as well. The Hepsia Control Panel will grant you total control over the caching platform and, with no more than one single mouse click, you’ll be able to clear the cached data, to view a log or to reboot an instance.

Varnish in VPS Servers

You can take advantage of Varnish with all our VPS server plans at no additional charge, since the data caching platform is pre-installed and is available by default. The sole condition is that the VPS server must be ordered with the Hepsia hosting Control Panel, through which you will be able to activate Varnish for any of your Internet sites with only a few clicks. Each VPS plan includes a different amount of system memory for content caching purposes, but you’ll get minimum several hundred MB, which is sufficient enough even for several resource-intensive sites. Soon after you activate the Varnish platform, it will start caching the content that your website visitors request, so you will notice the significantly better page load speeds and the decreased load on your VPS server in no time. Varnish will permit you to use a less expensive virtual machine, as you will not need that much power to sustain the correct operation of your websites even if you run popular Internet sites with multiple visitors. Optimum results are accomplished if the sites that use the Varnish platform use also a dedicated IP address.

Varnish in Dedicated Servers

All Linux dedicated servers that are ordered with the tailor-made Hepsia website hosting Control Panel include Varnish, which is among the pre-installed platforms that you’ll get with the dedicated server. The Varnish caching platform can be set up and managed without any effort via Hepsia’s user-friendly graphical interface and, with no more than one single mouse click, you can see a comprehensive log, add or restart an instance, delete the cached files for any website and much more. Soon after you configure the Varnish platform for a specific domain or sub-domain, it will begin caching the webpages requested by your website visitors and as soon as it has cached enough content, you’ll observe a tremendously better site performance and a reduced load on the dedicated machine. With Varnish-dedicated system memory starting at 3 GB, you’ll be able to use the software platform for workload distribution purposes even if you host a huge number of websites on your machine.
