Varnish is a website accelerator platform, which caches info for the sake of faster access. It’s sometimes referred to as an HTTP reverse proxy too and it works between a web server and its users. When a visitor loads a specific web page, its content is requested by the Internet browser, and then the web server handles this request and returns the necessary data. If Varnish is enabled for a website, it will cache its pages on the very first visit and in case the visitor visits a cached page for a second time, the information will be delivered by the accelerator platform and not by the web server. The boosted loading speed is a result of the much faster response speed that the Varnish platform offers as compared to any web server software. Of course, this does not mean that the website visitors will keep being served the exact same content again and again, because any update on any of the web pages is reflected in the content that the Varnish platform stores in its system memory.
Varnish in Cloud Web Hosting
If you host your websites under a cloud web hosting
account with our company, you’ll be able to add Varnish with a couple of clicks of the mouse from your hosting Control Panel. The caching platform is available as an upgrade with all our shared hosting packages and you can select 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 Control Panel’s Upgrades section are the amount of memory and the number of instances and they aren’t tied directly to each other, so you can choose whether you want lots of memory for one large-size website or less memory for multiple smaller ones. You can take advantage of the full potential of the Varnish caching platform in case the sites use a dedicated IP. Using the hosting Control Panel, you can swiftly start/restart/terminate an instance, clear the cached data independently for each website that uses the Varnish platform or view a comprehensive log.
Varnish in Semi-dedicated Servers
The Varnish data caching platform is part of the default set of services that you will get when you decide to host your websites in a semi-dedicated server
account. You can configure it for any of your Internet sites via our leading-edge Hepsia Control Panel. The default memory that Varnish can use to cache data is 64 megabytes, but in case you decide that you want more, you can upgrade this amount 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 caching platform simultaneously. Since these two features aren’t bound to each other, you can use several instances with the default memory or you can add more memory in increments of 32 megabytes and use all of it for a single website. The Varnish caching platform works best when you use a dedicated IP address for the websites that utilize its power. Hepsia will offer you an easy way of rebooting any instance. What’s more, you’ll be able to delete the cached data with just one single click.
Varnish in VPS Servers
We provide Varnish with all Hepsia-equipped VPS servers
, so in case you purchase a server with this hosting Control Panel, you’ll be able to make full use of the content caching platform at no extra charge. Varnish can use different amounts of memory for caching purposes depending on the particular configuration that you have picked during the subscription process, but in any case, this amount won’t be less than several hundred megabytes. This is more than enough to improve the work of several different large websites, so the better web page browsing speeds and the decreased load on your virtual machine will be noticeable. The effect may not be evident momentarily, as Varnish will need a certain amount of time to cache the content that visitors open, but shortly after you set it up, you will feel its full capacity. This platform will permit you to use a less powerful VPS server and to give less cash to get the same performance you’d get with a higher-end virtual machine without Varnish.
Varnish in Dedicated Servers
You can use Varnish in order to increase the loading speed of any website that is hosted on a dedicated server
from us when the Hepsia hosting Control Panel is installed on it. Not only will you get the platform ready to be used at no additional fee, but you will also exert complete control over it through Hepsia’s simple-to-navigate GUI. It’ll take only one click to start or terminate an instance or to clear the cached files for any Internet site that’s using Varnish and if you’re more experienced, you can also check the platform’s logs. Varnish comes with no less than 3 gigabytes of virtual memory for content caching purposes, so even in case you run lots of websites on your server and they all use the Varnish caching platform, the difference in their performance will be evident. You will simply have to wait for a little while till Varnish caches whatever content the site visitors access on their end. The Varnish platform works best if the websites use a dedicated IP, but due to the fact that our dedicated servers include three free IP addresses, you will have all that you need.
