Learn precisely what Varnish is. Get to know a lot more about web accelerators and their role.
Varnish is a web application accelerator platform, which caches data for the sake of faster response times. It is sometimes referred to as a caching HTTP reverse proxy too and it works between a web server and a web browser. When a visitor loads a specific web page, the content is requested by the Internet browser, and then the web server processes this browser request and returns the needed data. If Varnish is activated for a certain site, it will cache the pages on the first visit and in case the user opens a cached page for a second time, the information will be delivered by the caching platform and not by the web server. The accelerated speed is an end result of the considerably faster response speed that Varnish offers as compared to any web server software. At the same time, this doesn’t mean that the website visitors will continue being served the exact same content again and again, as any change on any of the web pages is reflected in the content that Varnish saves in its memory.
Varnish in Shared Hosting
If you host your Internet sites in a shared hosting
account with our company, you’ll be able to activate Varnish with a couple of mouse clicks through your hosting Control Panel. The platform is available as an optional upgrade with all our hosting packages and you can select 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 features that can be upgraded in the Control Panel’s Upgrades section are the number of instances and the amount of system memory and they are not directly linked to each other, so you can choose if you need lots of memory for a single large site or less memory for several smaller ones. You can make use of the full potential of the Varnish platform in case the sites use a dedicated IP address. With the hosting Control Panel, you can quickly start/restart/terminate an instance, clear the cached contents individually for each website which uses Varnish or view an elaborate log file.
Varnish in Semi-dedicated Servers
Varnish is a feature, which comes by default with all Linux semi-dedicated servers
that we’re offering and you can use it for load balancing purposes. It is available in your Hepsia hosting Control Panel. The data caching platform comes with 64 MB of system memory for cached data storing purposes and you can use it with any website that you host in your semi-dedicated account. In case you are in need of more than that, you can increase the memory quota. The memory itself is available in increments of 32 megabytes in the Upgrades section of the Control Panel. The same Upgrades section will permit you to enable more instances as well, if you’d like to use Varnish with more websites. The two things can be ordered independently – you can cache the content of a single large-size Internet site or run a number of Internet sites with the default memory allocation. You can get the most out of the Varnish caching platform in case you use a dedicated IP address and you can get one with your semi-dedicated server plan as well. Hepsia will give you full control over the caching platform and, with no more than one single click of the mouse, you’ll be able to clear the cached files, to check a system log file or to reboot an instance.
Varnish in VPS Servers
The Varnish content caching platform comes by default with each of the VPS servers
offered by our company given that the machine is ordered with the Hepsia Control Panel, so you can enhance the work of your sites with only a few mouse clicks. The more powerful the plan, the more memory will be available to Varnish, but even with a lower-end plan, the platform will be able to utilize several hundred MB, so even if you run a number of Internet sites, you will notice a serious decrease in the server load and a substantially faster page load speed. The platform will need to work for a little while while the visitors navigate the website and once the content has been cached, you will notice the result. One of the benefits of employing Varnish is that a less powerful and less expensive Virtual Private Server package will do the very same job as a more pricey one without the caching platform, so not only will your Internet sites perform much better, but you will also save some money.
Varnish in Dedicated Servers
In case you order a dedicated server
with the Hepsia hosting Control Panel, you’ll get the Varnish caching platform at no additional fee and you’ll have complete control over it through a truly simple-to-work-with graphical interface – you’ll be able to start, to stop or to reboot an instance, to check an exhaustive system log, to delete the cache for any website and much more. The Varnish caching platform will have several GB of memory at its disposal, so even if you run frequently visited Internet sites with an enormous number of visitors, you’ll notice the tremendously better website load speeds and the decreased load on the machine. This will become a fact soon after you begin using Varnish, since it will need a certain amount of time to cache the website content that users open. You can take full advantage of the platform’s capacity if the sites that are using it also use a dedicated IP address, but owing to the fact that your dedicated server includes a few IPs by default, you will not need to pay anything on top of your monthly fee for the machine itself.
