Varnish is a website accelerator platform, which caches content for the sake of faster access. It is occasionally referred to as an HTTP reverse proxy too and it works between a web server and an Internet browser. When a website visitor accesses a specific web page, the content is requested by the browser, and then the web server handles this browser request and delivers the necessary data. If Varnish is activated for a particular site, it will cache its pages at the first visit and if the visitor opens a cached page for a second time, the info will be delivered by the caching platform instead of the server. The increased loading speed is an end result of the much faster response time that Varnish offers compared to any server software. Of course, this does not mean that the site visitors will continue being served the very same content over and over again, as any update on any of the web pages is reflected in the content that Varnish saves in its memory.
Varnish in Shared Hosting
You can use Varnish’s full potential and improve the speed of your sites irrespective of the shared hosting package that you have selected and you can add and configure the content caching platform with several mouse clicks via the simple-to-use GUI offered by our cutting-edge Hepsia Control Panel. In the meantime, you’ll be able to select two different things – how many Internet sites will use the Varnish platform, 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 tied to the number of instances, so you can order more instances with less memory and the other way around. In case you’ve got plenty of content on a given website and you win plenty of website visitors, more memory will guarantee you better results. You may also consider using a dedicated IP address for the Internet sites that will use the Varnish caching platform. The Hepsia Control Panel will provide you with easy 1-click buttons for deleting or rebooting any instance, for erasing the cache associated with each site and for viewing detailed system logs.
Varnish in Semi-dedicated Hosting
The Varnish content caching platform is included in the default set of services that you’ll obtain when you decide to host your websites under a semi-dedicated server account. You can set it up for any of your Internet sites through our leading-edge Hepsia Control Panel. The default system memory that the Varnish caching platform can use to cache content is 64 MB, but in case you decide that you want more, you can upgrade this memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, in other words – the number of the Internet sites that can use this caching platform at the same time. Since these two things are not bound to each other, you can use a few websites with the default memory or you can get more memory in increments of 32 megabytes and use all of it for a single Internet site. The Varnish caching platform performs best if you get a dedicated IP address for the websites that utilize its power. Hepsia will provide you with a simple means of rebooting any instance. Furthermore, you will be able to clear the cached content with just one mouse click.
Varnish in Dedicated Servers Hosting
If you order a dedicated server with the Hepsia Control Panel, you will acquire Varnish at no additional fee and you’ll exert full control over it via an incredibly user-friendly interface – you will be able to start, to discontinue or to restart an instance, to view a comprehensive system log, to clear the cache for any website and much, much more. Varnish will have several gigabytes of virtual memory at its disposal, so even if you have resource-requiring websites with plenty of visitors, you’ll notice the considerably faster web page loading times and the less load on your dedicated server. This will become a fact shortly after you begin using the Varnish platform, since it will require a certain amount of time to cache the site content that users browse. You can get the most out of the platform’s capability in case the sites that are using it also use a dedicated IP address, but owing to the fact that your server includes a few IPs by default, you won’t need to pay anything on top of your monthly charge for the server itself.
