Varnish is a website accelerator platform, which caches information for the sake of faster response times. It is sometimes referred to as an HTTP reverse proxy too and it works between a web server and an Internet browser. When a website visitor loads a certain page, its content is requested by the web browser, and then the web server handles this browser request and returns the requested information. If Varnish is enabled for a certain website, it will cache its pages at the first visit and if the user visits a cached page once more, the info will be delivered by the accelerator platform instead of the web server. The increased load speed is an end result of the much faster response speed that Varnish offers as compared to any web server software. Of course, this does not mean that the users will keep being served the same content over and over again, since any modification on any of the pages is reflected in the content that the Varnish platform caches in its memory.

Varnish in Web Hosting

You can unleash Varnish’s full potential and boost your websites’ load speed irrespective of the web hosting package that you’ve picked and you can activate and set up the content caching platform with several mouse clicks through the user-friendly GUI offered by our advanced Hepsia Control Panel. During the procedure, you’ll be able to choose two separate things – how many websites will use the Varnish platform, in other words – the number of instances, and how much information will be cached, i.e. the amount of memory. The latter is offered in increments of 32 megabytes and is not tied to the number of instances, so you can add more instances with less memory and vice versa. If you have a lot of content on a given Internet site and you attract a lot of website visitors, more memory will give you better results. You may also consider employing a dedicated IP address for the websites that will use the Varnish platform. Hepsia will provide you with easy 1-click controls for stopping or rebooting any instance, for erasing the cache for each Internet site and for viewing comprehensive system logs.

Varnish in Semi-dedicated Servers

Varnish comes as standard with all semi-dedicated hosting service that we offer and you can use it for load balancing purposes. It’s available in your Hepsia hosting Control Panel. The content caching platform comes with 64 megabytes of system memory for cached content storing purposes and you can use it with any website that you host in the semi-dedicated account. In case you are in need of more than that, you can increase the system memory allowance. The memory itself is offered in increments of 32 MB in the Upgrades section of the Control Panel. The very same Upgrades section will enable you to create more instances too, if you’d like to use the Varnish caching platform with more websites. The two things can be added separately – you can cache the content of one resource-consuming site or run a number of websites with the default memory allowance. You can get the most out of the Varnish platform if you have a dedicated IP and you can order one with your semi-dedicated package as well. The Hepsia Control Panel will give you total control over the caching platform and, with no more than one single click of the mouse, you will be able to clear the cache, to see a system log file or to restart an instance.

Varnish in VPS Servers

We offer Varnish with all Hepsia-managed Linux VPS web hosting service, so if you obtain a VPS with this web hosting Control Panel, you’ll be able to make use of the content caching platform at no additional fee. The Varnish platform can use different amounts of system memory for content caching purposes depending on the very sever setup that you’ve selected during the registration process, but nevertheless, this amount will not be less than several hundred MB. This is quite enough to improve the overall performance of several different heavy websites, so the better website load speeds and the reduced load on your server will be perceivable. The effect may not be observable right away, as Varnish will need some time to cache the website content that visitors request, but shortly after you activate it, you will feel its full capacity. This platform will allow you to use a lower-end server and to pay less cash to get the exact same performance you would get with a higher-end virtual machine without Varnish.

Varnish in Dedicated Servers

If you order a dedicated server with the Hepsia hosting Control Panel, you will obtain the Varnish caching platform at no additional cost and you’ll have complete control over it via a very intuitive graphical interface – you will be able to start, to remove or to restart an instance, to browse an elaborate system log, to delete the cache associated with any website and much, much more. The Varnish platform will have several GB of memory at its disposal, so even if you host resource-requiring sites with a large number of visitors, you’ll notice the tremendously better page load speeds and the decreased load on your server. This will become a fact shortly after you start using the Varnish platform, since it will require a certain amount of time to cache the pages that users request. You can take full advantage of the platform’s capabilities if the websites that are using it also use a dedicated IP address, but due to the fact that your server comes with a few IP addresses by default, you won’t have to pay anything on top of the monthly fee for the machine itself.
