Varnish is a website accelerator platform, which caches info for the sake of quicker access. It is occasionally referred to as a caching HTTP reverse proxy as well and it interacts between a web server and a browser. When a website visitor opens a certain web page, the content is requested by the browser, and then the web server handles this browser request and returns the needed data. If Varnish is enabled for a certain website, it will cache the pages on the first visit and if the user visits a cached page again, the information will be delivered by the accelerator platform instead of the server. The improved speed is an end result of the much faster response speed that Varnish offers as compared to any web server software. Of course, this doesn’t mean that the users will continue seeing the very same content again and again, as any change on any of the web pages is reflected in the content that Varnish stores in its memory.
Varnish in Website Hosting
If you host your sites in a website hosting account with us, you will be able to add Varnish with several clicks of the mouse via your Control Panel. The platform is offered as an optional upgrade with all our hosting plans and you can choose the number of the sites that will use it and the maximum amount of system memory that will be available for the cached data. The two upgradeable features in the Control Panel’s Upgrades section are the number of instances and the amount of system memory and they are not directly linked to each other, so you can choose if you want a lot of memory for one single large-size website or less memory for several smaller ones. You can unlock the full potential of Varnish in case the sites use a dedicated IP address. With the Control Panel, you can effortlessly start/reboot/disable an instance, clear the cached content independently for each website that uses the Varnish platform or see an exhaustive system log.
Varnish in Semi-dedicated Servers
The Varnish content caching platform is included in the basic service set that you will get when you choose to host your Internet sites under a semi-dedicated server account. You can set it up for any of your Internet sites through our next-generation Hepsia hosting Control Panel. The default amount of system memory that the Varnish platform can use to cache content is 64 megabytes, but if you decide that you want more, you can upgrade this amount from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, in other words – the number of the websites that can use this caching platform simultaneously. As these two features are not linked to each other, you can use a few Internet sites with the default memory or you can order more memory in increments of 32 MB and use all of it for a single website. Varnish works best when you set a dedicated IP address for the websites that utilize its power. The Hepsia Control Panel will give you an easy means of rebooting any instance. What’s more, you will be able to delete the cached data with just one single click.
Varnish in VPS Servers
We provide Varnish with all of the Hepsia-managed VPS servers, so if you acquire a VPS with this Control Panel, you’ll be able to use the content caching platform at no extra fee. Varnish can utilize different amounts of system memory for content caching purposes based on the specific VPS package that you have selected during the subscription process, but at any rate, this amount won’t be less than several hundred MB. This is more than enough to boost the overall performance of a number of resource-heavy websites, so the better page loading speeds and the lowered load on the VPS server will be perceivable. The result may not be detectable momentarily, as Varnish will need some time to cache the site content that people browse, but shortly after you activate it, you will witness its full potential. This platform will permit you to use a lower-end VPS server and to give less cash to get the very same performance you’d get with a higher-end virtual machine without Varnish.
Varnish in Dedicated Servers
You can employ Varnish in order to accelerate the load speed of any website that is hosted on a dedicated server with our company if the Hepsia hosting Control Panel is pre-installed on the machine. Not only will you get the data caching platform ready to be used at no additional fee, but you will also exert total control over it via the Hepsia Control Panel’s intuitive GUI. It will take only one single click of the mouse to start or terminate an instance or to delete the cached content associated with any Internet site that’s using Varnish and if you are more proficient, you can also view the platform’s logs. Varnish comes with at least 3 GB of system memory for site content caching purposes, so even if you host an enormous number of websites on your machine and they all use the platform, the difference in their performance will be distinguishable. You’ll simply need to wait for a while until Varnish caches whatever webpages the site visitors browse on their end. The Varnish platform performs best if the websites use a dedicated IP address, but owing to the fact that our servers include 3 cost-free IP addresses, you will have all that you need.
