Varnish is a website accelerator platform, which caches data for faster response times. It is occasionally referred to as a caching HTTP reverse proxy as well and it works between a web server and a browser. When a site visitor opens a certain webpage, the content is requested by the browser, and then the web server handles this request and sends back the required info. If Varnish is enabled for a particular website, it will cache the pages on the very first request and in case the visitor accesses a cached page for a second time, the content will be delivered by the caching platform and not by the server. The accelerated loading speed is a result of the significantly faster response speed that the Varnish platform offers compared with any web server software. At the same time, this doesn’t mean that the website visitors will continue being served the very same content over and over again, since any update on any of the pages is reflected in the content that Varnish keeps in its system memory.
Varnish in Hosting
Varnish is available as an optional upgrade with each and every hosting plan and if you would like to use it, you can add it to your shared web hosting account via the Upgrades section in your Hepsia Control Panel. There are two different things that can be upgraded – the instances and the memory. The first one refers to the number of the sites that you wish to employ Varnish for, whereas the second, which is offered in increments of 32 MB, pertains to the maximum amount of content that the content caching platform can store at any particular time. The Hepsia Control Panel’s simple-to-work-with graphical interface will allow you to switch off or to restart any instance, to check elaborate system logs or to erase the platform’s cache with just one click. For maximum results, you can employ a dedicated IP address for the sites that will use the caching platform. With Varnish, your website will load substantially faster, which means more satisfied visitors and potential customers.
Varnish in Semi-dedicated Servers
Varnish is part of the standard service set that you’ll receive when you choose to host your websites in a semi-dedicated server account. You can set it up for any of your websites through 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 in case you decide that you need more, you can upgrade this amount of memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, in other words – the number of the sites that can use this caching platform simultaneously. Since these two features aren’t tied to each other, you can use a few Internet sites 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 platform performs best if you use a dedicated IP for the websites that utilize its power. The Hepsia Control Panel will give you a simple means of rebooting any instance. Furthermore, you will be able to delete the cached contents with just one single mouse click.
Varnish in VPS Servers
We provide Varnish with all of the Hepsia-equipped VPS plans, so if you buy a VPS with this web hosting Control Panel, you’ll be able to take full advantage of the caching platform at no extra charge. Varnish can use different amounts of system memory for caching purposes based on the specific sever setup that you’ve chosen during the subscription process, but in any case, this amount won’t be less than several hundred MB. This is more than enough to improve the performance of a handful of resource-consuming sites, so the better site load speeds and the lowered load on your server will be perceivable. The effect may not be observable right away, since the Varnish platform will need a certain amount of time to cache the site content that visitors browse, but soon after you activate it, you will observe its full potential. This platform will permit you to use a less powerful VPS and to pay less cash to get the exact same performance you’d get with a higher-end machine without Varnish.
Varnish in Dedicated Servers
You can use Varnish in order to improve the loading speed of any site that is hosted on a dedicated server with us when the Hepsia Control Panel is pre-installed on the machine. Not only will you get the content caching platform ready to be used at no additional charge, but you will also have full control over it via the Hepsia Control Panel’s simple-to-work-with interface. It will take just one single click of the mouse to start or terminate an instance or to delete the cached data associated with any website that’s using the Varnish platform and in case you are more advanced, you can also browse the platform’s system logs. Varnish comes with no less than three gigabytes of system memory for site content caching purposes, so even in case you host an enormous number of websites on your server and they all use the platform, the difference in their performance will be perceivable. You’ll just have to wait for a little while until Varnish caches whatever webpages the site visitors browse on their end. The platform performs best when the Internet sites use a dedicated IP address, but considering the fact that our dedicated servers come with three cost-free IPs, you will have all that you need.
