Learn just what Varnish is. Discover a lot more about web accelerators and their goal.
Varnish is a web application accelerator platform, which caches information for the sake of faster response times. It is occasionally referred to as an HTTP reverse proxy as well and it interacts between a web server and a web browser. When a site visitor opens a specific webpage, its content is requested by the Internet browser, and then the server processes this request and sends back the necessary information. If Varnish is activated for a site, it will cache the pages at the very first request and in case the user opens a cached page once again, the content will be delivered by the caching platform instead of the server. The accelerated load speed is an end result of the much faster response speed that Varnish offers compared with any server software. At the same time, this doesn’t mean that the users will keep seeing the exact same content over and over again, as any update on any of the pages is reflected in the content that Varnish keeps in its system memory.
Varnish in Web Hosting
In case you host your sites under a web hosting
account with our company, you’ll be able to activate Varnish with several mouse clicks via your Control Panel. The data caching platform is available as an optional upgrade with all our web hosting plans and you can choose how many websites will use it and the maximum amount of system memory that will be used for the cached data. The two features that can be upgraded in the Control Panel’s Upgrades section are the number of instances and the amount of system memory and they are not tied directly to each other, so you can choose if you want lots of memory for one single large website or less memory for multiple smaller ones. You can use the full potential of Varnish if the sites use a dedicated IP. With the Control Panel, you can effortlessly start/restart/shut down an instance, delete the cached content independently for each site which uses Varnish or check a detailed log file.
Varnish in Semi-dedicated Servers
The semi-dedicated servers
that we’re offering will permit you to employ Varnish once your new account has been set up, since the platform is available by default. 64 megabytes of system memory will be allocated to Varnish the moment your account is enabled, so you can make use of this load balancing software once your site has been published on the Internet. In case you’re in need of more memory, you can order 32 megabytes at a time from the Upgrades section of the Hepsia Control Panel and it will be assigned to your semi-dedicated server momentarily. You can also increase the number of the websites that employ Varnish, or the so-called ‘instances’, which are not linked directly to the amount of system memory that you use, which means that you will have more freedom. The Varnish caching platform will significantly decrease the server load produced by your websites, so your visitors can enjoy fast-opening pages. You’ll be able to manage the Varnish platform without efforts via your Control Panel using fast-access controls. You will be able to start/shut down any of the instances that you’ve got, to clear the cache associated with any of your websites or to see system logs.
Varnish in VPS Servers
We offer Varnish with all Hepsia-equipped VPS servers
, so if you purchase a server with this Control Panel, you’ll be able to make full use of the caching platform at no additional cost. Varnish can utilize different amounts of memory for caching purposes depending on the particular Virtual Private Server package that you have chosen during the VPS order process, but nevertheless, this amount won’t be less than several hundred MB. This is quite enough to improve the work of a number of popular Internet sites, so the better page loading speeds and the decreased load on the virtual server will be discernible. The effect may not be visible instantly, as the Varnish platform will require some time to cache the content that users browse, but soon after you set it up, you’ll witness its full potential. This platform will permit you to use a lower-end Virtual Private Server and to give less money to get the very same performance you’d get with a higher-end virtual machine without Varnish.
Varnish in Dedicated Servers
You can use Varnish in order to improve the speed of any website that’s hosted on a dedicated server
from our company if the Hepsia hosting Control Panel is pre-installed on the machine. Not only will you get the data caching platform ready for use at no extra cost, but you will also exert complete control over it via the Hepsia Control Panel’s easy-to-navigate interface. It will take just one mouse click to start or deactivate an instance or to delete the cached files associated with any website that’s using the Varnish platform and if you are more knowledgeable, you can also view the platform’s logs. Varnish comes with no less than 3 GB of system memory for caching purposes, so even if you host a vast number of sites on your machine and they all use the Varnish platform, the improvement in their overall performance will be evident. You’ll simply need to wait for a little while until Varnish caches whatever webpages the site visitors access on their end. The platform works best when the websites use a dedicated IP address, but due to the fact that our dedicated servers come with three charge-free IPs, you will have all that you need.
