Varnish is a web application accelerator platform, which caches info for quicker response times. It is occasionally called a caching HTTP reverse proxy too and it interacts between a web server and an Internet browser. When a visitor loads a given webpage, its content is requested by the Internet browser, and then the web server handles this browser request and sends back the needed info. If Varnish is activated for a website, it will cache the pages on the first request and in case the visitor opens a cached page for a second time, the content will be delivered by the accelerator platform and not by the web server. The improved speed is an end result of the considerably faster response time that the Varnish platform offers compared with any server software. Of course, this does not mean that the visitors will continue seeing the same content again and again, because any modification on any of the pages is reflected in the content that Varnish caches in its system memory.
Varnish in Cloud Website Hosting
If you host your websites in a cloud website hosting
account with our company, you’ll be able to add Varnish with several clicks of the mouse via your Control Panel. The data caching platform is available as an optional upgrade with all our web hosting packages and you can choose how many websites will use it and the total storage space that will be available for the cached data. The two upgradeable features in the Upgrades section of the Control Panel are the amount of system memory and the number of instances and they aren’t directly linked to each other, so you can decide whether you need lots of memory for a single large site or less memory for several smaller ones. You can make use of the full potential of the Varnish caching platform if the sites use a dedicated IP address. With the hosting Control Panel, you can swiftly start/reboot/stop an instance, delete the cached contents independently for each site that uses Varnish or view an elaborate system log file.
Varnish in Semi-dedicated Servers
The Varnish caching platform is included in the standard service set that you’ll acquire when you choose to host your sites in a semi-dedicated server
account. You can set it up for any of your sites through our innovative Hepsia Control Panel. The default amount of memory that the Varnish platform can use to cache content is 64 MB, but in case you decide that you need more, you can upgrade this amount 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 platform at the same time. Since these two features are not tied to each other, you can use a few websites with the default memory or you can order more memory in increments of 32 MB and use all of it for a single site. The Varnish platform works best when you set a dedicated IP for the Internet sites that utilize its power. Hepsia will offer you a simple way of rebooting any instance. Furthermore, you’ll be able to clear the cached contents with only a click.
Varnish in VPS Servers
You can use the workload balancing capabilities of Varnish with each of our VPS servers
if you choose Hepsia as your hosting Control Panel. The Varnish content caching platform comes by default and the amount of memory that it will be able to use to cache your website content is dependent on the particular VPS plan that you’ve picked, but even with the less powerful plans, you’ll have no less than several hundred MB of system memory at your disposal exclusively for content caching purposes. This amount is enough to boost the performance of multiple sites. It’ll take a little time for you to observe the results, since the Varnish platform caches the content that website visitors open, but shortly thereafter you will notice the significantly lowered load on the VPS and the accelerated site loading speed. The Varnish caching platform will allow you to make use of a lower-end Virtual Private Server package for websites that would normally need a more expensive web hosting solution.
Varnish in Dedicated Servers
In case you order a dedicated server
with the Hepsia Control Panel, you’ll acquire the Varnish data caching platform at no additional charge and you will exert total control over it via an exceptionally easy-to-use interface – you will be able to start, to cancel or to restart an instance, to browse an exhaustive system log, to delete the cache for any Internet site and much more. The Varnish caching platform will have several GB of virtual memory at its disposal, so even if you own busy sites with an enormous number of visitors, you will notice the tremendously faster website loading times and the reduced load on your dedicated server. This will happen shortly after you begin using Varnish, since it will require some time to cache the content that people request. You can make the most of the platform’s capability in case the sites that are using it also use a dedicated IP address, but due to the fact that your server comes with a couple of IP addresses by default, you won’t need to pay anything on top of your monthly charge for the server itself.
