Varnish is a web app accelerator platform, which caches content for faster response times. It’s occasionally called a caching HTTP reverse proxy as well and it works between a web server and an Internet browser. When a site visitor loads a given webpage, its content is requested by the Internet browser, and then the web server handles this request and returns the needed information. If Varnish is enabled for a specific website, it will cache its pages on the first visit and in case the visitor opens a cached page again, the information will be delivered by the caching platform instead of the web server. The improved load speed is an end result of the substantially faster response time that the Varnish platform offers as compared to any web server software. At the same time, this doesn’t mean that the users will keep being served the very same content again and again, because any modification on any of the pages is reflected in the content that the Varnish platform stores in its system memory.
Varnish in Shared Web Hosting
In case you host your websites under a shared web hosting
account with us, you’ll be able to add Varnish with several mouse clicks from your Control Panel. The caching platform is offered as an upgrade with all our shared hosting packages and you can choose the number of the websites that will use it and the total amount of system memory that will be available for the cached content. The two upgradeable features in the Upgrades section of the Control Panel are the amount of memory and the number of instances and they are not directly tied to each other, so you can choose if you need a lot of memory for a single large-size website or less memory for multiple smaller ones. You can unleash the full potential of the Varnish platform in case the sites use a dedicated IP address. Using the hosting Control Panel, you can swiftly start/reboot/discontinue an instance, delete the cached contents individually for each site that uses the Varnish platform or see an elaborate log file.
Varnish in Semi-dedicated Servers
The Linux semi-dedicated servers
that we are offering will permit you to employ Varnish once your new semi-dedicated server account has been created, since the caching platform comes by default. 64 megabytes of system memory will be allocated to Varnish the moment your account is activated, so you can take advantage of this workload distribution software as soon as your website has been launched. If you need more system memory, you can order 32 MB at a time from the Upgrades section of the Hepsia hosting Control Panel and it will be allocated to your semi-dedicated server in a flash. You can also increase the number of the Internet sites that employ Varnish, or the so-called ‘instances’, which are not directly bound to the amount of system memory that you use, which means that you’ll enjoy more versatility. The Varnish caching platform will greatly decrease the load on the server caused by your websites, so your visitors can enjoy fast-loading web pages. You’ll be able to manage the Varnish caching platform with ease through your Control Panel using fast-access controls. You’ll be able to start/deactivate any of the instances that you have, to delete the cache associated with any of your sites or to view system log files.
Varnish in VPS Servers
We provide Varnish with all Hepsia-managed VPS servers
, so in case you order a server with this web hosting Control Panel, you will be able to make the most of the content caching platform at no additional charge. The Varnish platform can utilize different amounts of memory for caching purposes depending on the particular VPS package that you’ve selected during the signup process, but in any case, this amount won’t be less than several hundred MB. This is quite enough to enhance the work of several traffic-hungry websites, so the better page loading speeds and the less load on the machine will be perceptible. The effect may not be visible immediately, as Varnish will require a certain amount of time to cache the content that users open, but shortly after you enable it, you will feel its full capacity. This caching platform will permit you to use a less powerful Virtual Private Server and to pay less cash to get the exact same performance you’d get with a more powerful virtual machine without Varnish.
Varnish in Dedicated Servers
All dedicated web hosting plans
that are ordered with the in-house built Hepsia web hosting Control Panel come with Varnish, which is one of the pre-installed software platforms that you’ll get with the server. The Varnish platform can be set up and administered effortlessly via Hepsia’s user-friendly GUI and, with no more than one click of the mouse, you can browse an elaborate log, create or restart an instance, delete the cache associated with any website and much, much more. Shortly after you enable Varnish for a particular domain or sub-domain, it will start caching the pages browsed by the site visitors and once it has cached enough content, you’ll observe a significantly better website performance plus a reduced load on the server. With Varnish-dedicated system memory starting at 3 GB, you’ll be able to use the software platform for load distribution purposes even if you run lots of sites on your dedicated machine.
