Varnish is a web app accelerator platform, which caches content for the sake of faster access. It’s sometimes referred to as a caching HTTP reverse proxy too and it works between a web server and its users. When a site visitor opens a particular web page, its content is requested by the Internet browser, and then the server handles this browser request and returns the requested content. If Varnish is activated for a given site, it will cache the pages on the very first visit and in case the user opens a cached page again, the info will be delivered by the accelerator platform instead of the server. The accelerated speed is an end result of the significantly faster response speed that Varnish offers as compared to any server software. Of course, this does not mean that the users will continue seeing the very same content over and over again, since any update on any of the pages is reflected in the content that the Varnish platform caches in its memory.
Varnish in Website Hosting
Varnish comes as an optional upgrade with each and every Linux website hosting package and if you wish to use it, you can add it to your website hosting account via the Upgrades section in your Hepsia hosting Control Panel. There’re two different things that can be upgraded – the instances and the memory. The first one refers to the number of the Internet sites that you wish to use Varnish for, whereas the second, which is offered in increments of 32 MB, indicates the maximum amount of data that the data caching platform can cache at any given moment. The Hepsia Control Panel’s easy-to-work-with graphical interface will allow you to cancel or to reboot any instance, to see detailed system logs or to clear the platform’s cache with just one click. For best results, you can use a dedicated IP for the sites that will use the caching platform. With Varnish, your website will load much faster, which means more happy visitors and potential customers.
Varnish in Semi-dedicated Hosting
The Varnish caching platform is included in the default service set that you’ll acquire in case you choose to host your Internet sites under a semi-dedicated server account. You can configure it for any of your sites via our leading-edge Hepsia Control Panel. The default amount of memory that the Varnish platform can use to cache data is 64 megabytes, but in case you decide that you need more, you can upgrade this memory from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, i.e. the number of the sites that can use this caching platform simultaneously. As these two features are not tied to each other, you can use several instances with the default amount of memory or you can get more memory in increments of 32 megabytes and use all of it for one single web site. The Varnish caching platform works best when you get a dedicated IP address for the Internet sites that utilize its power. Hepsia will provide you with a simple way of restarting any instance. Also, you’ll be able to delete the cached content with just one click of the mouse.
Varnish in VPS Hosting
You can take full advantage of the workload balancing potential of Varnish with each of our Linux VPS hosting packages in case you choose Hepsia as your web hosting Control Panel. The content caching platform comes by default and the memory that it’ll be able to use to cache your website content is dependent upon the specific package that you have chosen, but even with the lower-end plans, you’ll have no less than several hundred MB of memory at your disposal only for caching purposes. This amount is sufficient enough to enhance the performance of numerous websites. It will take a little time for you to notice the results, since the Varnish platform caches the content that site visitors open, but shortly thereafter you’ll notice the substantially decreased load on your virtual machine and the accelerated website load speed. The Varnish caching platform will allow you to use a less powerful VPS package for websites that would typically need a more costly hosting solution.
Varnish in Dedicated Web Hosting
In case you order a dedicated server with the Hepsia hosting Control Panel, you’ll acquire the Varnish content caching platform at no additional fee and you’ll exert full control over it via an incredibly user-friendly GUI – you’ll be able to start, to disable or to restart an instance, to see an exhaustive log, to clear the cache for any site and much more. The Varnish platform will have several gigabytes of system memory at its disposal, so even if you have large websites with a huge number of visitors, you will notice the much better website load speeds and the decreased load on your dedicated machine. This will become a fact shortly after you begin using Varnish, as it will require some time to cache the pages that visitors open. You can take full advantage of the platform’s capabilities if the sites that are using it also use a dedicated IP address, but since your server comes with several IPs by default, you will not have to pay anything on top of your monthly charge for the machine itself.
