Varnish is a web app accelerator tool, which has been gaining a lot in popularity in recent years, because it can increase the speed of any Internet site, at times even by one hundred percent, based on the content itself. This tool is sometimes called a caching HTTP reverse proxy as well and is used to lower the overall load on the physical machine and to accelerate the browsing speed for the website visitors. Each time a visitor accesses a page on a given Internet site, the web browser request is processed by the web server and the requested information is served as a reply. If Varnish is activated, it caches the pages that the site visitor opens and if any of them is accessed again, it is delivered by Varnish and not by the web server directly. The boost in the overall performance comes from the fact that the accelerator processes the web requests considerably faster than any web server, which leads to much faster browsing speeds for the users. In case any content is changed in the meantime, the cached web pages will also be ‘refreshed’ the next time someone accesses them.
Varnish in Hosting
Varnish is available as an optional upgrade with each hosting and if you wish to use it, you can add it to your shared account via the Upgrades section in your Hepsia Control Panel. There’re two separate things that can be upgraded – the instances and the system memory. The first one depends on the number of the websites that you want to employ Varnish for and the second one, which is offered in increments of 32 MB, refers to the total amount of content that the content caching platform can store at any particular moment. Hepsia’s simple-to-work-with interface will allow you to delete or to reboot any instance, to check comprehensive logs or to get rid of the platform’s cache with just one mouse click. For best results, you can employ a dedicated IP for the sites that will use the platform. With Varnish, your site will load significantly faster, which means more satisfied website visitors and potential customers.
Varnish in Semi-dedicated Hosting
All our semi-dedicated hosting services come with Varnish by default, so you can use the web application accelerator tool and increase the loading speed of any website that you host on our platform. You will get 64 megabytes of memory particularly for the Varnish accelerator at no extra charge and you’ll be able to create an instance with no more than a few clicks of the mouse through the Hepsia Control Panel, which is included with the semi-dedicated packages. In case you need more memory, the latter is offered in increments of 32 megabytes through the Upgrades section of the Control Panel and it will be available to you instantaneously. You can also add more instances as an upgrade, so you can decide if plenty of content will be cached for a single site or if the available memory will be utilized by different sites. The Hepsia Control Panel will allow you to restart or to delete any instance, to check the system log for it or to delete the cached content using 1-click controls. To take full advantage of the Varnish accelerator, you can assign a dedicated IP to the sites which will use it.
Varnish in VPS Web Hosting
You can use the load balancing capabilities of Varnish with all our Linux VPS web hosting services in case you select Hepsia as your web hosting Control Panel. The caching platform is offered by default and the amount of system memory that it’ll be able to use to cache your site content depends on the particular Virtual Private Server plan that you’ve picked, but even with the lower-end packages, you’ll have at least several hundred megabytes of memory at your disposal solely for caching purposes. This amount is sufficient to enhance the work of numerous sites. It will take some time for you to observe the results, as Varnish caches the content that visitors browse, but shortly after that you’ll notice the considerably less load on the virtual server and the accelerated website browsing speed. Varnish will allow you to use a less powerful VPS plan for websites which would typically require a more expensive hosting solution.
Varnish in Dedicated Servers Hosting
If you order a dedicated server with the Hepsia hosting Control Panel, you’ll get the Varnish content caching platform at no extra fee and you will have full control over it through an amazingly time and effort saving graphical interface – you’ll be able to start, to cancel or to reboot an instance, to browse an elaborate system log, to delete the cache associated with any website and much more. Varnish will have several GB of virtual memory at its disposal, so even if you host traffic-heavy sites with multiple visitors, you’ll notice the substantially faster page load speeds and the reduced load on your server. This will happen soon after you begin using Varnish, since it will require a certain amount of time to cache the content that visitors browse. You can take full advantage of the platform’s capability if the Internet sites that are using it use also a dedicated IP, but since your server comes with a few IPs by default, you won’t need to pay anything on top of the monthly fee for the machine itself.
