Varnish is a web application accelerator, which has been gaining a lot of popularity in recent years, because it can increase the speed of any site, at times even by 100 percent, based on the content itself. This tool is sometimes called an HTTP reverse proxy too and is used to decrease the overall load on the physical server and to increase the access speed for the site visitors. Each time a visitor accesses a page on a specific website, the web browser request is handled by the web server and the requested data is sent as a reply. If Varnish is activated, it caches the web pages that the website visitor browses and in case any of them is loaded once more, it is fetched by Varnish and not by the web server directly. The boost in the overall performance is due to the fact that the accelerator processes the web requests considerably quicker than any web server, which results in much faster browsing speeds for the visitors. In case any content is changed meanwhile, the cached web pages will also be ‘refreshed’ the next time someone tries to access them.
Varnish in Shared Web Hosting
You can use Varnish’s full potential and improve your sites’ loading speed irrespective of the shared web hosting package that you’ve chosen and you can activate and set up the data caching platform with a couple of mouse clicks using the user-friendly interface offered by our cutting-edge Hepsia hosting Control Panel. In the meantime, you’ll be able to choose two different things – how many sites will use Varnish, in other words – the number of instances, and how much information will be cached, i.e. the amount of system memory. The latter is offered in increments of 32 megabytes and is not bound to the number of instances, so you can use more instances and less memory and vice versa. If you’ve got plenty of content on a certain site and you get plenty of site visitors, more system memory will give you a better result. You may also consider employing a dedicated IP for the sites that will use the Varnish caching platform. Hepsia will offer you easy 1-click controls for deleting or restarting any instance, for deleting the cache associated with each Internet site and for checking detailed system logs.
Varnish in Semi-dedicated Hosting
The Varnish platform is included in the standard service set that you’ll obtain when you choose to host your sites under a semi-dedicated server account. You can set it up for any of your websites via our innovative Hepsia Control Panel. The default system memory that Varnish can use to cache data is 64 MB, but in case you decide that you want more, you can upgrade this amount from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, in other words – the number of the websites that can use this caching platform at the same time. Since these two things are not linked to each other, you can use several Internet sites with the default amount of memory or you can add more memory in increments of 32 megabytes and use all of it for one single website. Varnish performs best when you get a dedicated IP for the Internet sites that utilize its power. Hepsia will provide you with a simple way of rebooting any instance. In addition, you will be able to delete the cached contents with only one click of the mouse.
Varnish in VPS Web Hosting
You can use the load balancing potential of Varnish with each of our Linux VPS web hosting if you choose Hepsia as your Control Panel. The Varnish data caching platform is available by default and the memory that it will be able to utilize to cache your website content is dependent on the particular Virtual Private Server plan that you have selected, but even with the less powerful packages, you will have no less than several hundred MB of memory at your disposal exclusively for data caching purposes. This amount is sufficient to enhance the performance of multiple websites. It’ll take a little time for you to distinguish the effects, since the Varnish platform caches the content that website visitors access, but soon after that you’ll notice the significantly less load on your VPS server and the enhanced site load speed. The Varnish platform will allow you to make use of a lower-end package for Internet sites that would typically require a more high-priced hosting solution.
Varnish in Dedicated Servers Hosting
You can use Varnish in order to accelerate the speed of any website that is hosted on a dedicated server from our company if the Hepsia Control Panel is installed on it. Not only will you get the caching platform ready to be used at no extra charge, but you’ll also exert full control over it through the Hepsia Control Panel’s easy-to-work-with interface. It’ll take just one single click to start or discontinue an instance or to clear the cached files for any site that is using the Varnish platform and if you are more proficient, you can also see the platform’s logs. Varnish comes with at least 3 gigabytes of virtual memory for data caching purposes, so even in case you host a huge number of websites on your machine and they all use the caching platform, the difference in their overall performance will be noticeable. You will just need to wait for a little while until Varnish caches whatever content the website visitors open on their end. The platform works best when the websites use a dedicated IP, but since our dedicated servers come with 3 cost-free IP addresses, you’ll have all that you need.
