Varnish is a web accelerator platform, which caches information for the sake of quicker response times. It’s sometimes referred to as a caching HTTP reverse proxy too and it works between a web server and a web browser. When a site visitor loads a specific page, its content is requested by the Internet browser, and then the web server processes this request and delivers the requested data. If Varnish is activated for a site, it will cache its pages on the first visit and in case the user visits a cached page again, the content will be delivered by the caching platform and not by the web server. The accelerated speed is a result of the substantially faster response speed that the Varnish platform offers as compared to any web server software. At the same time, this does not mean that the site visitors will keep being served the exact same content over and over again, as any modification on any of the pages is reflected in the content that Varnish stores in its memory.

Varnish in Cloud Web Hosting

In case you host your websites in a cloud web hosting account with our company, you will be able to add Varnish with several clicks through your Control Panel. The content caching platform comes as an optional upgrade with all our plans 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 upgradeable features in the Control Panel’s Upgrades section are the number of instances and the amount of memory and they’re not directly linked to each other, so you can choose whether you want a lot of memory for one large website or less memory for several smaller ones. You can use the full potential of the Varnish platform in case the websites use a dedicated IP. Using the Control Panel, you can quickly start/reboot/discontinue an instance, clear the cached content independently for each website which uses the Varnish platform or check an exhaustive system log.

Varnish in Semi-dedicated Servers

The Linux semi-dedicated plans that we’re offering will permit you to use Varnish once your brand-new semi-dedicated server account has been activated, since the platform is offered by default. 64 MB of system memory will be assigned to Varnish the moment your account is activated, so you can make use of this load distribution software as soon as your site has been built. In case you’re in need of more memory, you can order 32 megabytes at a time from the Upgrades section of the Hepsia Control Panel and it will be allocated to your semi-dedicated server instantly. You can also increase the number of the websites that employ Varnish, or the so-called ‘instances’, which are not directly bound to the amount of memory that you use, which suggests that you will enjoy more flexibility. The Varnish platform will significantly decrease the load produced by your sites, so your site visitors can enjoy fast-loading web pages. You’ll be able to manage the Varnish caching platform without any effort through the Control Panel using fast-access controls. You’ll be able to start/stop any of the instances that you have, to clear the cached content associated with any of your Internet sites or to see system logs.

Varnish in VPS Servers

You can take full advantage of the workload balancing potential of Varnish with each of our Linux VPS servers in case you pick Hepsia as your Control Panel. The Varnish data caching platform is available by default and the amount of system memory that it will be able to utilize to cache the content of your sites depends upon the particular Virtual Private Server plan that you’ve picked, but even with the lower-end packages, you’ll have no less than several hundred MB of memory at your disposal solely for content caching purposes. This amount is sufficient to boost the work of numerous websites. It’ll take some time for you to see the effects, as Varnish caches the content that website visitors open, but shortly after that you will notice the significantly less load on the server and the enhanced website browsing speed. The Varnish caching platform will allow you to make use of a lower-end package for Internet sites that would usually require a more costly hosting service.

Varnish in Dedicated Servers

If you order a dedicated server with the Hepsia hosting Control Panel, you’ll obtain Varnish at no additional charge and you will have total control over it through a very simple-to-navigate GUI – you’ll be able to start, to remove or to reboot an instance, to check a detailed system log, to clear the cached content for any site and much more. The Varnish platform will have several GB of memory at its disposal, so even if you have resource-heavy sites with many visitors, you’ll notice the tremendously better website load times and the decreased load on the dedicated server. This will become a fact soon after you start using the Varnish platform, as it will need some time to cache the content that people request. You can take full advantage of the platform’s potential if the Internet sites that are using it also use a dedicated IP, but owing to the fact that your dedicated server includes several IPs by default, you won’t need to pay anything on top of your monthly charge for the machine itself.
