Varnish is a web application accelerator tool, which has been gaining a lot of popularity lately, as it can increase the load speed of any Internet site, at times even by one hundred percent, depending on the content itself. This tool is sometimes called a caching HTTP reverse proxy too and is used to lower the overall load on the physical machine and to accelerate the access speed for the website visitors. Every time a visitor opens a page on a specific Internet site, the web browser request is handled by the web server and the requested information is returned as a reply. If Varnish is activated, it caches the web pages that the visitor opens and if any of them is accessed once more, it is fetched by Varnish and not by the server directly. The increase in the performance is due to the fact that the accelerator processes the browser requests significantly faster than any web server, which results in much faster browsing speeds for the website visitors. If any content is modified meanwhile, the cached web pages will also be ‘refreshed’ the next time someone accesses them.
Varnish in Shared Hosting
You can unleash Varnish’s potential and enhance the loading speed of your websites regardless of the shared hosting plan that you’ve selected and you can add and set up the content caching platform with several clicks via the easy-to-use graphical interface offered by our cutting-edge Hepsia Control Panel. During the process, you’ll be able to select two different things – how many websites will employ the Varnish platform, i.e. 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 MB and is not bound to the number of instances, so you can order more instances and less memory and the other way around. If you’ve got lots of content on a particular site and you attract many site visitors, more memory will guarantee you better results. You may also consider using a dedicated IP for the websites that will use Varnish. Hepsia will provide you with simple 1-click controls for switching off or rebooting any instance, for deleting the cache associated with each site and for viewing elaborate system logs.
Varnish in Semi-dedicated Hosting
All our Linux semi-dedicated hosting packages come with Varnish by default, so you can take advantage of the web app accelerator tool and enhance the loading speed of any site that you host on our semi-dedicated servers. You’ll get 64 megabytes of system memory exclusively for Varnish at no extra fee and you will be able to create an instance with no more than a few clicks of the mouse through the Hepsia Control Panel, which comes with the semi-dedicated server packages. If you need more memory, the latter is available in increments of 32 MB in the Control Panel’s Upgrades section and it will be available to you right away. You can also order more instances as a separate upgrade, so you can decide whether a lot of data will be cached for a single site or if the available memory will be utilized by different Internet sites. The Hepsia Control Panel will enable you to restart or to stop any instance, to check the system log file for it or to clear the cached content using single-click controls. To take full advantage of Varnish, you can set a dedicated IP address for the websites that will employ it.
Varnish in VPS
We provide Varnish with all of the Hepsia-managed Linux VPS packages, so in case you obtain a VPS with this hosting Control Panel, you will be able to use the content caching platform at no additional charge. The Varnish platform can utilize different amounts of system memory for content caching purposes depending on the specific server configuration that you’ve selected during the server order process, but nevertheless, this amount won’t be less than several hundred MB. This is quite enough to boost the work of a number of resource-requiring Internet sites, so the better page loading speeds and the lowered load on your virtual server will be perceptible. The result may not be obvious straight away, as the Varnish platform will need some time to cache the website content that people access, but shortly after you activate it, you’ll perceive its full capacity. This platform will permit you to use a less powerful server and to pay less cash to get the same performance you would get with a more powerful virtual machine without Varnish.
Varnish in Dedicated Hosting
You can use Varnish in order to increase the speed of any site 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 content caching platform ready for use at no additional fee, but you’ll also exert complete control over it through Hepsia’s intuitive GUI. It’ll take only one single click of the mouse to start or terminate an instance or to clear the cached content associated with any website that’s using Varnish and if you are more proficient, you can also view the platform’s system logs. Varnish comes with no less than 3 gigabytes of system memory for content caching purposes, so even in case you host a vast number of Internet sites on your machine and they all use the Varnish platform, the difference in their overall performance will be distinguishable. You will only need to wait for a while till Varnish caches whatever content the website visitors load on their end. The platform works best if the Internet sites use a dedicated IP, but owing to the fact that our dedicated servers come with three free-of-charge IP addresses, you will have all that you need.
