Varnish is a web app accelerator platform, which caches info for quicker access. It is sometimes referred to as a caching HTTP reverse proxy as well and it interacts between a web server and its users. When a site visitor accesses a specific webpage, its content is requested by the Internet browser, and then the server processes this browser request and sends back the necessary content. If Varnish is enabled for a particular site, it will cache its pages at the first request and if the visitor visits a cached page once again, the info will be delivered by the accelerator platform and not by the web server. The accelerated load speed is a result of the substantially faster response time that Varnish offers compared to any server software. Of course, this doesn’t mean that the visitors will keep being served the exact same content again and again, as any modification on any of the web pages is reflected in the content that Varnish keeps in its system memory.
Varnish in Cloud Web Hosting
Varnish comes as an optional upgrade with all our cloud web hosting
. You can add it to your website hosting account from the Hepsia hosting Control Panel, which is available with all shared hosting packages and you will get an amazingly easy-to-use GUI, which will grant you full control over the data caching platform. Using 1-click fast-access controls, you can restart or deactivate any of the instances, i.e. Varnish will no longer be activated for a certain Internet site. You can also see a comprehensive system log file or delete the cache for any of the sites. When you add Varnish to your shared hosting package, you will be able to select the maximum amount of system memory that will be available to you for content caching purposes and the number of the websites that will use Varnish. You can always order more memory in increments of 32 megabytes and, for optimal performance, you can assign a dedicated IP address to the websites that will use Varnish. This will allow you to take full advantage of your sites and to have plenty of happy visitors.
Varnish in Semi-dedicated Servers
Varnish is included in the basic service set that you’ll acquire when you choose to host your websites in 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 if you decide that you need more, you can upgrade this memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, i.e. the number of the Internet sites that can use this platform simultaneously. As these two things aren’t linked to each other, you can use a couple of websites with the default memory or you can add more memory in increments of 32 MB and use all of it for a single website. Varnish works best when you assign a dedicated IP address to the Internet sites that utilize its power. The Hepsia Control Panel will offer you an easy way of rebooting any instance. In addition, you will be able to clear the cached contents with just one single click of the mouse.
Varnish in VPS Servers
You can use the workload balancing potential of Varnish with each of our VPS service
if you choose Hepsia as your Control Panel. The Varnish content caching platform comes by default and the amount of system memory that it will be able to utilize to cache the content of your websites is dependent on the given plan that you have picked, but even with the lower-end plans, you will have no less than several hundred megabytes of system memory at your disposal only for caching purposes. This amount is enough to boost the performance of numerous websites. It will take some time for you to see the results, as Varnish caches the content that visitors access, but shortly after that you’ll notice the considerably less load on your server and the accelerated site load speed. The Varnish caching platform will allow you to make use of a lower-end Virtual Private Server plan for sites that would normally require a more expensive hosting service.
Varnish in Dedicated Servers
If you order a dedicated server
with the Hepsia hosting Control Panel, you’ll acquire Varnish at no extra cost and you’ll exert complete control over it through a very easy-to-work-with interface – you will be able to start, to discontinue or to reboot an instance, to see an elaborate log, to delete the cached data for any site and much, much more. Varnish will have several GB of virtual memory at its disposal, so even if you have high-demand websites with a huge number of visitors, you will notice the significantly faster web page loading times and the less load on the dedicated machine. This will become a fact shortly after you begin using Varnish, as it will need a certain amount of time to cache the website content that visitors access. You can make the most of the platform’s capability in case the websites that are using it also use a dedicated IP address, but since your server includes a couple of IPs by default, you will not need to pay anything on top of the monthly fee for the machine itself.
