Learn about Varnish, understand more about website accelerators and see precisely what it is that they can do.
Varnish is a web application accelerator, which has been gaining a lot of popularity in recent years, as it can increase the loading speed of any website, at times even by 100%, depending on the content. This tool is sometimes called an HTTP reverse proxy as well and is used to reduce the overall load on the server and to increase the browsing speed for the website visitors. Anytime a visitor accesses a page on a certain Internet site, the browser request is processed by the web server and the requested content is sent as a response. If the Varnish accelerator is enabled, it caches the pages that the site visitor browses and if any of them is accessed once more, it is served by Varnish and not by the web server directly. The improvement in the overall performance comes from the fact that the accelerator handles the web requests considerably quicker than any web server, which results in much faster browsing speeds for the users. If any data is modified meanwhile, the cached web pages will also be ‘refreshed’ the next time someone tries to open them.
Varnish in Hosting
You can unlock Varnish’s full potential and optimize your sites’ speed regardless of the hosting
package that you’ve chosen and you can activate and configure the content caching platform with a few clicks from the simple-to-work-with graphical interface offered by our leading-edge Hepsia Control Panel. During the process, you will be able to choose two separate things – how many sites will use the Varnish caching platform, in other words – the number of instances, and how much info will be cached, in other words – the amount of memory. The latter is available in increments of 32 megabytes and is not linked to the number of instances, so you can use more instances with less memory and the other way around. In case you’ve got plenty of content on a certain website and you gain many website visitors, more system memory will guarantee you better results. You may also consider employing a dedicated IP address for the sites that will use Varnish. Hepsia will offer you simple 1-click buttons for deleting or restarting any instance, for deleting the cache for each website and for checking exhaustive logs.
Varnish in Semi-dedicated Servers
Varnish is included by default with all semi-dedicated hosting plans
that we’re offering and you can use it for workload distribution purposes. It is available in your Hepsia hosting Control Panel. The Varnish caching platform comes with 64 MB of system memory for cached content storing purposes and you can employ it with any site that you host in the semi-dedicated server account. If you need more, you can increase the system memory quota. The memory itself is offered in increments of 32 MB in the Upgrades section of the Control Panel. The very same Upgrades section will enable you to activate more instances as well, if you wish to use the Varnish platform with multiple sites. The two upgrades can be ordered independently – you can cache the content of one resource-demanding website or run several different websites with the default memory allowance. You can get the most out of Varnish 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 give you complete control over the platform and, with no more than one single click of the mouse, you’ll be able to clear the cached content, to check a system log or to restart an instance.
Varnish in VPS Servers
We offer Varnish with all of the Hepsia-equipped VPS hosting plans
, so in case you purchase a VPS with this web hosting Control Panel, you’ll be able to make use of the content caching platform at no additional fee. Varnish can utilize different amounts of system memory for caching purposes based on the specific plan that you’ve picked during the registration process, but at any rate, this amount won’t be less than several hundred MB. This is quite enough to improve the performance of several resource-demanding Internet sites, so the faster site load speeds and the less load on your Virtual Private Server will be perceptible. The result may not be observable momentarily, as Varnish will need some time to cache the content that visitors open, but shortly after you set it up, you’ll observe its full potential. This caching platform will allow you to use a less powerful VPS and to pay less cash to get the same performance you’d get with a more powerful machine without Varnish.
Varnish in Dedicated Servers
You can use Varnish to speed up any website that is hosted on a dedicated server
from our company when the Hepsia 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 total control over it through the Hepsia Control Panel’s intuitive graphical interface. It’ll take only one click of the mouse to start or terminate an instance or to delete the cached data for any Internet site that’s using the Varnish platform and if you’re more practiced, you can also check the platform’s logs. Varnish comes with at least 3 gigabytes of virtual memory for website content caching purposes, so even if you host numerous Internet sites on your machine and they all use the caching platform, the improvement in their performance will be noticeable. You’ll just have to wait for a little while until Varnish caches whatever webpages the site visitors open on their end. The Varnish platform performs best when the Internet sites use a dedicated IP, but considering the fact that our dedicated servers include three cost-free IP addresses, you’ll have all that you need.
