Varnish is a web accelerator platform, which caches data for faster 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 visitor accesses a certain page, its content is requested by the web browser, and then the server handles this browser request and delivers the required info. If Varnish is enabled for a given website, it will cache the pages on the very first request and if the user accesses a cached page once again, the content will be delivered by the accelerator platform instead of the server. The increased load speed is a result of the significantly faster response time that the Varnish platform offers as compared with any web server software. Of course, this does not mean that the website visitors will keep being served the very same content again and again, because any modification on any of the web pages is reflected in the content that Varnish stores in its memory.

Varnish in Shared Web Hosting

In case you host your sites under a shared web hosting account with us, you will be able to add Varnish with several clicks via your Control Panel. The caching platform comes as an upgrade with all our shared hosting packages and you can select how many websites will use it and the total amount of system memory that will be available for the cached content. The two features that can be upgraded in the Upgrades section of the Control Panel are the amount of system memory and the number of instances and they are not directly linked to each other, so you can decide whether you need plenty of memory for one large-scale site or less memory for multiple smaller ones. You can unlock the full potential of the Varnish platform if the sites use a dedicated IP. With the hosting Control Panel, you can swiftly start/reboot/remove an instance, delete the cached files individually for each site that uses Varnish or see a detailed log.

Varnish in Semi-dedicated Hosting

Varnish is a feature, which is offered by default with all Linux semi-dedicated hosting that we’re offering and you can use it for load balancing purposes. It is available in your Hepsia hosting Control Panel. The Varnish content caching platform comes with 64 megabytes of system memory for cached data storing purposes and you can use it with any website that you host in your semi-dedicated account. In case you are in need of more, you can increase the system memory quota. The memory itself is available in increments of 32 MB in the Upgrades section of the Control Panel. The same section will allow you to create more instances as well, if you would like to use the Varnish caching platform with multiple sites. The two upgrades can be added independently – you can cache the content of one resource-absorbing Internet site or run several different sites with the default memory. You can take full advantage of the Varnish platform in case you have a dedicated IP and you can order one with your semi-dedicated server package as well. The Hepsia Control Panel will grant you complete control over the caching platform and, with no more than one click of the mouse, you’ll be able to delete the cached contents, to check a log or to reboot an instance.

Varnish in VPS Web Hosting

You can take full advantage of the workload balancing potential of Varnish with all our Linux VPS web hosting in case you choose Hepsia as your web hosting Control Panel. The platform is offered by default and the memory that it’ll be able to use to cache the content of your sites depends on the given VPS plan that you have picked, but even with the less powerful packages, you will have at least several hundred MB of memory at your disposal exclusively for caching purposes. This amount is sufficient to enhance the work of numerous Internet sites. It will take a little time for you to see the results, as Varnish caches the content that website visitors request, but shortly thereafter you’ll notice the significantly less server load and the increased site browsing speed. Varnish will allow you to make use of a lower-end Virtual Private Server plan for Internet sites that would usually need a more expensive web hosting service.

Varnish in Dedicated Servers Hosting

All dedicated servers hosting that are ordered with the tailor-made Hepsia web hosting Control Panel feature Varnish, which is one of the pre-installed platforms that you will get with the machine. The Varnish caching platform can be set up and administered without effort through the Hepsia Control Panel’s time and effort saving graphical interface and, with no more than a click, you can view a detailed log, add or reboot an instance, clear the cached data associated with any site and much more. Soon after you activate Varnish for a specific domain or subdomain, it will begin caching the web pages requested by the website visitors and once it has cached enough content, you’ll perceive a tremendously better site performance and a decreased load on your server. With Varnish-dedicated virtual memory starting at 3 gigabytes, you will be able to use the software platform for workload distribution purposes even if you host an enormous number of sites on the dedicated server.
