Varnish is a web app accelerator platform, which caches data for the sake of faster response times. It is occasionally referred to as an HTTP reverse proxy too and it works between a web server and a browser. When a site visitor opens a certain web page, the content is requested by the browser, and then the server handles this browser request and sends back the necessary info. If Varnish is activated for a website, it will cache its pages on the very first visit and if the visitor accesses a cached page again, the data will be delivered by the accelerator platform instead of the server. The boosted speed is a result of the much faster response speed that the Varnish platform offers as compared to any server software. At the same time, this does not mean that the website visitors will keep being served the very same content again and again, as any change on any of the pages is reflected in the content that the Varnish platform stores in its memory.

Varnish in Hosting

Varnish comes as an optional upgrade with each Linux hosting and if you wish to use it, you can add it to your shared web hosting account through the Upgrades menu in your Hepsia Control Panel. There are two separate features that can be upgraded – the instances and the memory. The first one refers to the number of the sites that you would like to use Varnish for, whereas the second, which comes in increments of 32 megabytes, indicates the total amount of data that the data caching platform can store at any given time. Hepsia’s user-friendly interface will enable you to disable or to reboot any instance, to check elaborate logs or to delete the platform’s cache with just one click. For best results, you can use a dedicated IP for the websites that will use the platform. With Varnish, your website will load significantly faster, which means more satisfied visitors and potential customers.

Varnish in Semi-dedicated Servers

The Varnish caching platform is an essential part of the basic set of services that you’ll receive if you decide to host your websites under a semi-dedicated server account. You can activate it for any of your websites via our cutting-edge Hepsia hosting Control Panel. The default system memory that the Varnish caching platform can use to cache content is 64 MB, but if you decide that you need more, you can upgrade this memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, in other words – the number of the Internet sites that can use this platform at the same time. As these two things are not bound to each other, you can use a few websites with the default memory or you can get more memory in increments of 32 MB and use all of it for one single web site. The Varnish platform performs best if you get a dedicated IP address for the sites that utilize its power. The Hepsia Control Panel will offer you a simple means of restarting any instance. What’s more, you will be able to delete the cached contents with only one single click of the mouse.

Varnish in VPS Servers

You can use the load balancing capabilities of Varnish with each of our Linux VPS servers in case you pick Hepsia as your Control Panel. The platform is available by default and the amount of system memory that it’ll be able to use to cache the content of your sites depends upon the given VPS package that you have picked, but even with the less powerful plans, you will have at least several hundred MB of system memory at your disposal solely for data caching purposes. This amount is sufficient enough to boost the overall performance of multiple Internet sites. It will take a little time for you to distinguish the effects, since the Varnish platform caches the content that website visitors open, but soon thereafter you’ll notice the considerably lowered load on the server and the improved site browsing speed. The Varnish caching platform will permit you to use a lower-end VPS plan for websites which would typically require a more expensive web hosting service.

Varnish in Dedicated Servers

All Linux dedicated servers which are ordered with the custom-built Hepsia hosting Control Panel include Varnish, which is one of the pre-installed platforms that you will get with the dedicated machine. The Varnish content caching platform can be configured and managed without any effort from Hepsia’s easy-to-work-with interface and, with no more than one single mouse click, you can check a comprehensive log, add or restart an instance, delete the cached content associated with any site and much, much more. Soon after you configure Varnish for a given domain or subdomain, it will start caching the pages opened by your visitors and as soon as it has cached enough content, you will observe a tremendously faster site performance plus a reduced load on the machine. With Varnish-dedicated memory starting at three gigabytes, you’ll be able to use the software platform for workload distribution purposes even if you run a huge number of sites on your server.
