Varnish is a web application accelerator platform, which caches info for the sake of faster response times. It is sometimes called a caching HTTP reverse proxy too and it interacts between a web server and a browser. When a visitor loads a given webpage, the content is requested by the web browser, and then the server processes this request and sends back the needed content. If Varnish is enabled for a specific website, it will cache the pages on the first visit and in case the visitor opens a cached page once again, the information will be delivered by the accelerator platform and not by the server. The accelerated load speed is an end result of the considerably faster response time that Varnish offers compared with any server software. At the same time, this does not mean that the website visitors will continue being served the very same content again and again, since any change on any of the pages is reflected in the content that the Varnish platform caches in its memory.
Varnish in Shared Website Hosting
Varnish comes as an optional upgrade with each Linux shared website hosting
and if you would like to use it, you can add it to your web hosting account using the Upgrades section in your Hepsia hosting Control Panel. There’re two separate things that can be upgraded – the number of instances and the memory. The first one depends on the number of the Internet sites that you would like to use Varnish for, whereas the second, which comes in increments of 32 MB, displays the total amount of data that the platform can cache at any given time. Hepsia’s intuitive GUI will enable you to discontinue or to restart any instance, to see comprehensive system logs or to delete the platform’s cache with just one mouse click. For best results, you can use a dedicated IP for the Internet sites that will use the caching platform. With Varnish, your site will open substantially faster, which means more happy website users and prospective customers.
Varnish in Semi-dedicated Servers
The Varnish platform is included in the basic set of services that you will receive in case you decide to host your Internet sites under a semi-dedicated server
account. You can set it up for any of your Internet sites through our next-generation Hepsia hosting Control Panel. The default memory that the Varnish platform can use to cache content is 64 MB, but if you decide that you need more, you can upgrade this amount of memory from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, in other words – the number of the Internet sites that can use this caching platform at the same time. Since these two features are not bound to each other, you can use several Internet sites with the default amount of memory or you can order more memory in increments of 32 megabytes and use all of it for one single site. Varnish works best if you allocate a dedicated IP to the websites that utilize its power. The Hepsia Control Panel will give you an easy means of rebooting any instance. Also, you will be able to delete the cached files with just one single mouse click.
Varnish in VPS Servers
You can take full advantage of the workload balancing potential of Varnish with any of our Linux VPS servers
if you select Hepsia as your Control Panel. The Varnish platform is available by default and the amount of system memory that it will be able to utilize to cache the content of your websites is dependent upon the specific Virtual Private Server plan that you have chosen, but even with the lower-end packages, you’ll have at least several hundred megabytes of system memory at your disposal solely for caching purposes. This amount is sufficient to enhance the overall performance of numerous sites. It’ll take a little time for you to notice the results, since the Varnish platform caches the content that website visitors open, but soon thereafter you will notice the considerably decreased load on the Virtual Private Server and the accelerated site browsing speed. The Varnish platform will permit you to make use of a lower-end Virtual Private Server package for sites that would normally require a more expensive web hosting service.
Varnish in Dedicated Servers
All dedicated servers
which are ordered with the custom Hepsia web hosting Control Panel include Varnish, which is among the pre-installed software platforms that you will get with the machine. The Varnish caching platform can be enabled and managed without efforts via the Hepsia Control Panel’s time and effort saving interface and, with no more than a click, you can see an exhaustive system log, add or reboot an instance, clear the cache associated with any Internet site and much, much more. Shortly after you set up Varnish for a certain domain or subdomain, it will begin caching the webpages requested by your site visitors and once it has cached enough content, you will observe a significantly faster website performance in addition to a decreased load. With Varnish-dedicated memory starting at 3 GB, you’ll be able to use the platform for load balancing purposes even if you run a large number of Internet sites on your dedicated machine.
