Varnish is a web app accelerator platform, which caches data for the sake of quicker response times. It is sometimes called a caching HTTP reverse proxy as well and it interacts between a web server and a browser. When a website visitor opens a given page, its content is requested by the Internet browser, and then the server processes this browser request and sends back the requested content. If Varnish is enabled for a website, it will cache its pages at the first visit and if the visitor accesses a cached page again, the content will be delivered by the caching platform instead of the server. The increased loading speed is a result of the substantially faster response time that the Varnish platform offers compared to any web server software. At the same time, this doesn’t mean that the users will keep being served the same content over and over again, because any update on any of the pages is reflected in the content that Varnish saves in its system memory.
Varnish in Cloud Hosting
Varnish comes as an optional upgrade with each cloud hosting and if you wish to use it, you can add it to your shared account using the Upgrades section in your Hepsia hosting Control Panel. There’re two separate things that can be upgraded – the instances and the system memory. The first one depends on the number of the sites that you want to employ Varnish for, whereas the second, which comes in increments of 32 megabytes, refers to the total amount of content that the content caching platform can store at any given time. Hepsia’s simple-to-use GUI will enable you to turn off or to reboot any instance, to see in-depth system logs or to erase the platform’s cache with just one mouse click. For maximum results, you can employ a dedicated IP for the Internet sites that will use the platform. With Varnish, your website will load substantially faster, meaning more happy visitors and potential customers.
Varnish in Semi-dedicated Servers
All our semi-dedicated servers come with Varnish by default, so you can make use of the web accelerator and improve the loading speed of any website that you host on our semi-dedicated servers. You will get 64 megabytes of system memory dedicated to the Varnish accelerator at no extra cost and you can activate an instance with no more than a couple of mouse clicks from the Hepsia Control Panel, which comes with the semi-dedicated server packages. In case you want more memory, the latter is available in increments of 32 megabytes through the Control Panel’s Upgrades section and it will be at your disposal instantaneously. You can also add more instances as a separate upgrade, so you can choose if a lot of data will be cached for a single website or if the memory will be used by different sites. The Hepsia Control Panel will enable you to restart or to cancel any instance, to check the system log file for it or to delete the cached data using one-click controls. To take full advantage of Varnish, you can allocate a dedicated IP address to the websites that will employ it.
Varnish in VPS Servers
You can use Varnish with all our VPS server plans at no additional charge, as the platform is pre-installed and is offered by default. The only precondition is that the VPS must come with the Hepsia hosting Control Panel, through which you will be able to set up Varnish for any of your Internet sites with just a few clicks. Each package includes a different amount of memory for content caching purposes, but you’ll have at least several hundred MB, which is enough even for several large-scale sites. Shortly after you activate Varnish, it will start caching the content that your website visitors open, so you’ll notice the considerably better site loading speeds and the less server load very soon. The Varnish platform will permit you to use a less pricey VPS server, as you won’t require that much power to guarantee the uninterrupted operation of your sites even if you manage resource-heavy websites with lots of visitors. Best results are achieved if the websites that use the Varnish platform also use a dedicated IP.
Varnish in Dedicated Servers
In case you order a dedicated server with the Hepsia hosting Control Panel, you will obtain the Varnish platform at no extra fee and you’ll have complete control over it through a rather time and effort saving graphical interface – you’ll be able to start, to terminate or to restart an instance, to check an elaborate system log, to delete the cache for any site and much more. Varnish will have several GB of system memory at its disposal, so even if you have traffic-consuming websites with numerous visitors, you’ll notice the significantly better page load speeds and the less load on your dedicated server. This will happen shortly after you begin using the Varnish platform, as it will require a certain amount of time to cache the website content that people request. You can take full advantage of the platform’s capacity if the sites that are using it use also a dedicated IP, but considering the fact that your dedicated server includes a couple of IP addresses by default, you will not need to pay anything on top of the monthly charge for the machine itself.
