Varnish is a web application accelerator platform, which caches content for faster response times. It is sometimes referred to as a caching HTTP reverse proxy too and it works between a web server and an Internet browser. When a website visitor loads a particular webpage, the content is requested by the web browser, and then the web server processes this browser request and sends back the required info. If Varnish is activated for a certain site, it will cache the pages on the first visit and if the user opens a cached page for a second time, the content will be delivered by the caching platform instead of the web server. The increased loading speed is an end result of the significantly faster response time that Varnish offers compared to any web server software. Of course, this does not mean that the visitors will continue seeing the 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 memory.

Varnish in Cloud Hosting

If you host your websites under a cloud hosting account with us, you’ll be able to add Varnish with a few clicks through your hosting Control Panel. The content caching platform comes as an upgrade with all our packages and you can select how many sites will use it and the total amount of system memory that will be used for the cached data. The two features that can be upgraded in the Control Panel’s Upgrades section are the number of instances and the amount of memory and they aren’t tied directly to each other, so you can choose if you want a lot of memory for one single large-sized website or less memory for several smaller ones. You can unleash the full potential of the Varnish platform if the sites use a dedicated IP address. Using the Control Panel, you can effortlessly start/reboot/deactivate an instance, clear the cached contents individually for each site which uses the Varnish platform or check an in-depth log file.

Varnish in Semi-dedicated Servers

The semi-dedicated servers offered by our company will allow you to use Varnish as soon as your brand new account has been activated, since the platform is available by default. 64 megabytes of system memory will be assigned to Varnish the second your account is activated, so you can use this load balancing software as soon as your site has been built. In case you are in need of more memory, you can get 32 megabytes at a time from the Hepsia hosting Control Panel’s Upgrades section and it will be assigned to your semi-dedicated machine momentarily. You can also increase the number of the sites that use Varnish, or the so-called ‘instances’, which are not directly linked to the amount of memory that you use, which means that you’ll have more versatility. The caching platform will significantly decrease the load on the semi-dedicated server caused by your sites, so your website visitors can enjoy fast-loading web pages. You will be able to manage the Varnish caching platform effortlessly from your Hepsia Control Panel using fast-access buttons. You will be able to start/shut down any of the instances that you have, to clear the cached data for any of your sites or to see system logs.

Varnish in VPS Servers

You can take full advantage of the workload balancing capabilities of Varnish with each of our VPS servers in case you pick Hepsia as your Control Panel. The content caching platform is offered by default and the memory that it will be able to utilize to cache your site content depends upon the specific package that you have chosen, but even with the lower-end plans, you will have at least several hundred megabytes of memory at your disposal solely for content caching purposes. This amount is sufficient enough to enhance the performance of numerous Internet sites. It will take some time for you to detect the effects, since the Varnish platform caches the content that website visitors request, but after that you’ll notice the considerably decreased load and the improved site browsing speed. The Varnish caching platform will allow you to use a lower-end plan for Internet sites that would normally need a more pricey web hosting solution.

Varnish in Dedicated Servers

In case you order a dedicated server with the Hepsia hosting Control Panel, you’ll get the Varnish platform at no additional charge and you will exert full control over it via a quite easy-to-work-with graphical interface – you’ll be able to start, to stop or to reboot an instance, to view a comprehensive log, to clear the cached files for any Internet site and much more. Varnish will have several GB of system memory at its disposal, so even if you own large-sized websites with many visitors, you will notice the considerably faster site loading speeds and the less load. This will happen shortly after you start using Varnish, since it will need a certain amount of time to cache the pages that users request. You can make the most of the platform’s capability in case the websites that are using it use also a dedicated IP address, but due to the fact that your server comes with several IP addresses by default, you won’t need to pay anything on top of the monthly fee for the server itself.
