Varnish is a web application accelerator platform, which caches data for the sake of faster response times. It’s occasionally called an HTTP reverse proxy too and it interacts between a web server and a web browser. When a visitor opens a specific web page, its content is requested by the browser, and then the server processes 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 request and in case the visitor accesses a cached page once more, the data will be delivered by the accelerator platform and not by the web server. The accelerated load speed is a result of the significantly faster response speed that Varnish offers compared with any web server software. At the same time, this does not mean that the website visitors will keep seeing the very same content over and over again, because any update on any of the pages is reflected in the content that the Varnish platform stores in its memory.

Varnish in Cloud Hosting

If you host your websites under a cloud hosting account with us, you will be able to add Varnish with a few mouse clicks via your Control Panel. The caching platform comes as an optional upgrade with all our hosting plans and you can choose the number of the websites that will use it and the maximum storage space that will be used 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 system memory and they aren’t linked directly to each other, so you can decide whether you need a lot of memory for one large-size site or less memory for multiple smaller ones. You can use the full potential of the Varnish caching platform in case the sites use a dedicated IP address. Using the Control Panel, you can effortlessly start/reboot/stop an instance, clear the cached contents individually for each site which employs the Varnish platform or see an elaborate log file.

Varnish in Semi-dedicated Hosting

The Varnish caching platform is part of the default set of services that you’ll get if you decide to host your websites in a semi-dedicated server account. You can activate it for any of your websites via our next-generation Hepsia hosting Control Panel. The default memory that the Varnish caching platform can use to cache content is 64 MB, but in case you decide that you want more, you can upgrade this 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 platform simultaneously. As these two features are not tied to each other, you can use a couple of instances with the default memory or you can add more memory in increments of 32 MB and use all of it for one single site. The Varnish caching platform works best when you set a dedicated IP address for the sites that utilize its power. Hepsia will offer you a simple means of restarting any instance. What’s more, you’ll be able to clear the cached contents with only a click.

Varnish in VPS Hosting

We provide Varnish with all Hepsia-managed Linux VPS hosting packages, so if you get a VPS with this hosting Control Panel, you will be able to make use of the content caching platform at no extra charge. The Varnish platform can use different amounts of memory for caching purposes depending on the very setup that you’ve selected during the server order process, but at any rate, this amount won’t be less than several hundred megabytes. This is quite enough to boost the work of several busy Internet sites, so the faster page browsing speeds and the less load on the VPS will be discernible. The result may not be visible straight away, since Varnish will need some time to cache the website content that visitors access, but soon after you enable it, you’ll perceive its full capacity. This platform will allow you to use a less powerful server and to give less cash to get the same performance you would get with a more powerful virtual machine without Varnish.

Varnish in Dedicated Web Hosting

If you order a dedicated server with the Hepsia hosting Control Panel, you’ll acquire the Varnish caching platform at no extra fee and you will exert total control over it via an extremely easy-to-navigate interface – you’ll be able to start, to deactivate or to restart an instance, to check an elaborate log, to delete the cached data associated with any website and much more. The Varnish platform will have several gigabytes of virtual memory at its disposal, so even if you manage traffic-heavy sites with lots of visitors, you’ll notice the tremendously better web page load times and the lowered load. This will become a fact shortly after you start using the Varnish platform, since it will require a certain amount of time to cache the pages that visitors request. You can take full advantage of the platform’s capacity if the Internet sites that are using it also use a dedicated IP address, but since your dedicated server includes a few IPs by default, you will not have to pay anything on top of the monthly fee for the machine itself.
