Varnish is a web accelerator platform, which caches content for faster response times. It is occasionally called a caching HTTP reverse proxy too and it interacts between a web server and a browser. When a website visitor loads a specific page, its content is requested by the web browser, and then the server processes this browser request and returns the requested content. If Varnish is activated for a website, it will cache the pages at the very first request and in case the user opens a cached page again, the information will be delivered by the caching platform instead of the server. The boosted speed is a result of the substantially faster response speed that Varnish offers as compared to any web server software. At the same time, this does not mean that the website visitors will continue seeing the very same content again and again, since any update on any of the pages is reflected in the content that the Varnish platform saves in its memory.

Varnish in Shared Hosting

You can unlock Varnish’s potential and enhance your websites’ load speed irrespective of the shared hosting package that you have selected and you can enable and set up the data caching platform with a couple of mouse clicks via the simple-to-work-with GUI offered by our next-generation Hepsia hosting Control Panel. During the procedure, you will be able to choose two different things – how many websites will use the Varnish platform, in other words – the number of instances, and how much info will be cached, in other words – the amount of system memory. The latter comes in increments of 32 megabytes and is not tied to the number of instances, so you can use more instances and less memory and the other way around. In case you have lots of content on a certain Internet site and you receive numerous website visitors, more system memory will guarantee you better results. You may also consider using a dedicated IP address for the Internet sites that will use Varnish. Hepsia will provide you with easy 1-click controls for terminating or rebooting any instance, for clearing the cache associated with any site and for seeing comprehensive system logs.

Varnish in Semi-dedicated Servers

The Varnish content caching platform is included in the basic set of services that you will get in case you choose to host your websites under a semi-dedicated server account. You can set it up for any of your websites through our next-gen Hepsia hosting Control Panel. The default amount of system memory that the Varnish platform can use to cache data is 64 megabytes, but in case you decide that you want more, you can upgrade this amount of memory from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, in other words – the number of the sites that can use this caching platform simultaneously. As these two features aren’t tied to each other, you can use several Internet sites with the default amount of memory or you can add more memory in increments of 32 megabytes and use all of it for a single site. The Varnish platform performs best when you get a dedicated IP address for the Internet sites that utilize its power. Hepsia will provide you with a simple means of restarting any instance. Furthermore, you’ll be able to clear the cached content with only one click of the mouse.

Varnish in VPS Servers

The Varnish platform is included by default with all VPS servers that we’re offering given that the VPS is ordered with the Hepsia hosting Control Panel, so you can optimize the work of your websites with just a couple of clicks of the mouse. The more powerful the package, the more memory will be available to Varnish, but even with a less powerful package, the platform will be able to utilize several hundred megabytes, so even if you run several sites, you will notice a noticeable reduction in the overall server load and a significantly faster website load speed. The Varnish caching platform will have to work for a while as the users navigate the website and once the site content has been cached, you’ll observe the effects. One of the advantages of using Varnish is that a lower-end and less pricey VPS plan will do the same job as a more pricey one without the platform, so not only will your websites work much better, but you will also spare some money.

Varnish in Dedicated Servers

If you order a dedicated server with the Hepsia hosting Control Panel, you will get the Varnish caching platform at no additional fee and you will exert complete control over it through a quite time and effort saving interface – you will be able to start, to disable or to restart an instance, to view an exhaustive system log, to delete the cached content associated with any Internet site and much, much more. Varnish will have several gigabytes of system memory at its disposal, so even if you manage large Internet sites with an immense number of visitors, you’ll notice the significantly faster site loading speeds and the lowered load on the server. This will become a fact shortly after you start using the Varnish platform, as it will need a certain amount of time to cache the web pages that visitors access. You can take full advantage of the platform’s capability in case the websites that are using it also use a dedicated IP address, but owing to the fact that your dedicated server includes several IPs by default, you won’t need to pay anything on top of your monthly charge for the machine itself.
