Learn exactly what Varnish is. Get to know much more about web accelerators and their purpose.
Varnish is a web application accelerator platform, which caches information for quicker access. It’s sometimes called a caching HTTP reverse proxy as well and it interacts between a web server and an Internet browser. When a website visitor loads a given webpage, its content is requested by the browser, and then the web server processes this browser request and delivers the required content. If Varnish is enabled for a given site, it will cache its pages at the very first visit and if the user opens a cached page once more, the information will be delivered by the accelerator platform instead of the web server. The improved load speed is an end result of the considerably faster response speed that Varnish offers as compared to any web server software. Of course, this doesn’t mean that the site visitors will keep seeing the very same content over and over again, as any modification on any of the web pages is reflected in the content that Varnish keeps in its memory.
Varnish in Shared Hosting
Varnish is available as an optional upgrade with all our Linux shared hosting packages
. You can add it to your account via the Hepsia Control Panel, which is offered with all shared packages and you will get a pretty user-friendly GUI, which will give you complete control over the caching system. Using 1-click quick-access buttons, you can reboot or terminate any of the instances, in other words – Varnish will no longer work for a given website. You can also see a detailed log or clear the cache associated with any of the Internet sites. When you add Varnish to your shared web hosting plan, you’ll be able to choose the total amount of memory that will be available to you for content caching purposes and how many sites will use Varnish. You can always add more memory in increments of 32 MB and, for maximum performance, you can set a dedicated IP for the sites that will use Varnish. This will permit you to take full advantage of your sites and to have a lot of satisfied visitors.
Varnish in Semi-dedicated Hosting
Varnish is offered as standard with all Linux semi-dedicated hosting packages
that we offer and you can use it for load distribution purposes. It’s available in your Hepsia Control Panel. The Varnish platform comes with 64 MB of system memory for cached content storing purposes and you can use it with any Internet site that you host in your account. If you are in need of more than that, you can increase the memory allowance. The memory itself is offered in increments of 32 megabytes in the Upgrades section of the Control Panel. The exact same section will permit you to add more instances too, in case you’d like to use Varnish with multiple sites. The two things can be ordered separately – you can cache the content of one single traffic-heavy website or use a number of sites with the default memory allowance. You can take full advantage of the Varnish platform in case you’ve got a dedicated IP address and you can order one with your semi-dedicated server plan as well. The Hepsia Control Panel will grant you total control over the caching platform and, with no more than one click of the mouse, you will be able to clear the cached contents, to check a log file or to reboot an instance.
Varnish in Dedicated Servers Hosting
You can employ Varnish to improve the loading speed of any website that is hosted on a dedicated server
from our company when the Hepsia hosting Control Panel is installed on the machine. Not only will you get the platform ready for use at no extra fee, but you will also have full control over it via Hepsia’s easy-to-navigate interface. It will take only a click to start or remove an instance or to delete the cached content associated with any Internet site that’s using Varnish and in case you’re more competent, you can also browse the platform’s logs. Varnish comes with no less than 3 gigabytes of system memory for website content caching purposes, so even in case you run an enormous number of sites on your server and they all use the caching platform, the difference in their performance will be obvious. You will just need to wait for a while till Varnish caches whatever web pages the site visitors load on their end. The Varnish platform performs best when the Internet sites use a dedicated IP address, but considering the fact that our dedicated servers come with 3 cost-free IP addresses, you will have everything you need.
