Varnish is a website accelerator platform, which caches info for quicker response times. It’s sometimes called a caching HTTP reverse proxy too and it works between a web server and a browser. When a site visitor opens a given web page, its content is requested by the web browser, and then the web server handles this browser request and delivers the needed content. If Varnish is activated for a particular website, it will cache the pages at the very first request and if the user visits a cached page once more, the information will be delivered by the caching platform and not by the server. The boosted load speed is a result of the considerably faster response speed that the Varnish platform offers compared with any web server software. At the same time, this doesn’t mean that the users will keep seeing the very same content over and over again, since any modification on any of the web pages is reflected in the content that Varnish stores in its system memory.
Varnish in Shared Hosting
In case you host your sites in a shared hosting
account with us, you will be able to activate Varnish with a few clicks via your Control Panel. The platform is offered as an optional upgrade with all our shared plans and you can choose how many websites will use it and the total storage space that will be used for the cached data. The two upgradeable features in the Control Panel’s Upgrades section are the number of instances and the amount of memory and they’re not tied directly to each other, so you can decide if you need lots of memory for one large-sized website or less memory for several smaller ones. You can unleash the full potential of Varnish in case the websites use a dedicated IP. With the hosting Control Panel, you can swiftly start/reboot/terminate an instance, delete the cached files independently for each website which employs the Varnish platform or check a comprehensive system log file.
Varnish in Semi-dedicated Servers
Varnish is included in the standard service set that you’ll receive if you decide to host your websites under a semi-dedicated server
account. You can enable it for any of your Internet sites via our next-gen Hepsia Control Panel. The default amount of memory that the Varnish platform can use to cache content is 64 MB, 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 caching platform at the same time. As these two features aren’t tied to each other, you can use several sites with the default memory or you can get more memory in increments of 32 megabytes and use all of it for one single website. The Varnish caching platform works best when you use a dedicated IP for the sites that utilize its power. The Hepsia Control Panel will give you a simple way of rebooting any instance. In addition, you’ll be able to delete the cached data with only one mouse click.
Varnish in Dedicated Servers
If you order a dedicated server
with the Hepsia hosting Control Panel, you’ll acquire the Varnish caching platform at no additional charge and you will have complete control over it through an amazingly easy-to-use interface – you will be able to start, to delete or to reboot an instance, to see an elaborate log, to clear the cached files for any site and much more. The Varnish platform will have several gigabytes of virtual memory at its disposal, so even if you manage traffic-intensive Internet sites with an immense number of visitors, you will notice the tremendously better web page loading speeds and the lowered load. This will become a fact shortly after you begin using the Varnish platform, as it will need some time to cache the site content that visitors request. You can get the most out of the platform’s capacity in case the Internet sites that are using it use also a dedicated IP, but owing to the fact that your server includes several IP addresses by default, you will not need to pay anything on top of the monthly charge for the machine itself.
