Varnish is a web app accelerator platform, which caches data for faster response times. It is sometimes called a caching HTTP reverse proxy too and it works between a web server and a browser. When a website visitor accesses a certain web page, the content is requested by the Internet browser, and then the server handles this request and returns the requested content. If Varnish is activated for a certain site, it will cache its pages at the very first request and if the user accesses a cached page once 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. Of course, this does not mean that the website visitors will keep seeing the very same content over and over again, because any modification on any of the pages is reflected in the content that the Varnish platform keeps in its system memory.
Varnish in Shared Hosting
You can unleash Varnish’s potential and improve the loading speed of your websites regardless of the shared hosting
plan that you have chosen and you can enable and set up the content caching platform with a few clicks using the simple-to-use GUI offered by our next-generation Hepsia Control Panel. In the meantime, you will be able to select two different things – how many sites will employ Varnish, i.e. the number of instances, and how much data will be cached, in other words – the amount of system memory. The latter is offered in increments of 32 MB and is not bound to the number of instances, so you can order more instances and less memory and vice versa. If you have a lot of content on a specific Internet site and you draw plenty of website visitors, more memory will guarantee you better results. You may also consider using a dedicated IP address for the Internet sites that will use Varnish. Hepsia will provide you with easy 1-click controls for stopping or restarting any instance, for deleting the cache associated with any Internet site and for checking in-depth system logs.
Varnish in Semi-dedicated Servers
Varnish is a feature, which comes by default with all semi-dedicated servers
that we’re offering and you can use it for load balancing purposes. It’s available in your Hepsia hosting Control Panel. The Varnish content caching platform comes with 64 megabytes of system memory for cached data storing purposes and you can use it with any Internet site that you host in your account. If you’re in need of more than that, you can increase the memory allocation. The memory itself is offered in increments of 32 megabytes through the Control Panel’s Upgrades section. The same section will enable you to activate more instances too, if you’d like to use the Varnish caching platform with multiple sites. The two things can be ordered separately – you can cache the content of one single large website or use a number of sites with the default memory. You can get the most out of the Varnish platform if you use a dedicated IP address and you can get one with your semi-dedicated server package as well. The Hepsia Control Panel will grant you full control over the platform and, with no more than one single mouse click, you’ll be able to clear the cached data, to view a system log or to restart an instance.
Varnish in VPS Servers
You can take advantage of Varnish with all our VPS server
plans at no extra cost, as the platform is pre-installed and is offered by default. The sole prerequisite is that the VPS must come with the Hepsia hosting Control Panel, through which you will be able to activate Varnish for any of your websites with just a couple of mouse clicks. Each Virtual Private Server package comes with a different amount of memory for data caching purposes, but you’ll get at least several hundred MB, which is sufficient even for several popular sites. Shortly after you enable Varnish, it’ll start caching the content that your website visitors browse, so you’ll notice the considerably faster webpage loading times and the lowered load on the Virtual Private Server in no time. The Varnish caching platform will permit you to use a less high-priced virtual server, since you won’t require that many resources to guarantee the correct operation of your Internet sites even if you’ve got traffic-hungry websites with many visitors. Optimum results are achieved if the sites that use the Varnish caching platform also use a dedicated IP.
Varnish in Dedicated Servers
All Linux dedicated service
which are ordered with the custom Hepsia web hosting Control Panel come with Varnish, which is one of the pre-installed platforms that you will get with the server. The Varnish content caching platform can be enabled and administered without any effort through the Hepsia Control Panel’s time and effort saving interface and, with no more than a click, you can see a detailed system log, create or reboot an instance, delete the cache associated with any site and much more. Soon after you configure the Varnish platform for a certain domain or subdomain, it will begin caching the pages requested by your site visitors and once it has cached enough web content, you’ll witness a tremendously faster website performance and a decreased load on your dedicated server. With Varnish-dedicated virtual memory starting at 3 gigabytes, you’ll be able to use the platform for workload balancing purposes even if you run numerous sites on the server.
