Varnish is a web application accelerator platform, which caches data for quicker access. It is occasionally referred to as an HTTP reverse proxy as well and it works between a web server and a web browser. When a site visitor loads a given page, its content is requested by the web browser, and then the web server handles this request and sends back the required information. If Varnish is enabled for a certain website, it will cache the pages on the very first request and if the user accesses a cached page once again, the content will be delivered by the accelerator platform and not by the web server. The accelerated speed is an end result of the significantly faster response speed that the Varnish platform offers compared with any web server software. At the same time, this doesn’t mean that the website visitors will keep being served the exact same content again and again, since any change on any of the web pages is reflected in the content that Varnish caches in its memory.
Varnish in Website Hosting
If you host your websites in a website hosting account with us, you’ll be able to add Varnish with several mouse clicks via your Control Panel. The caching platform is offered as an upgrade with all our shared hosting plans and you can select the number of the sites that will use it and the maximum 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 number of instances and the amount of system memory and they are not linked directly to each other, so you can choose if you want lots of memory for one single large-sized site or less memory for several smaller ones. You can unlock the full potential of the Varnish platform in case the websites use a dedicated IP. With the Control Panel, you can quickly start/restart/disable an instance, delete the cached data individually for each site that uses Varnish or check an elaborate log file.
Varnish in Semi-dedicated Hosting
Varnish comes by default with all Linux semi-dedicated hosting services offered by our company and you can use it for load distribution purposes. It’s available in your Hepsia hosting Control Panel. The Varnish content caching platform comes with 64 megabytes of system memory for cached content storing purposes and you can employ it with any site that you host in your semi-dedicated account. If you need 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 add more instances as well, in case you would like to use the Varnish caching platform with multiple sites. The two things can be added separately – you can cache the content of a single large-scale site or use several websites with the default memory allowance. You can take full advantage of the Varnish caching platform in case you’ve got a dedicated IP address and you can order one with your semi-dedicated plan as well. The Hepsia Control Panel will give you full control over the platform and, with no more than one single mouse click, you’ll be able to delete the cached files, to see a log or to reboot an instance.
Varnish in VPS Hosting
Varnish is included by default with all Linux VPS hosting offered by our company as long as the server is ordered with the Hepsia Control Panel, so you can boost the performance of your websites with only a couple of mouse clicks. The more powerful the package, the more system memory will be available to Varnish, but even with a lower-end plan, the caching platform will be able to utilize several hundred megabytes, so even if you have several different sites, you’ll notice a substantial reduction in the server load and a substantially faster web page load speed. The Varnish platform will have to work for a little while while the users browse the website and as soon as the content has been cached, you’ll see the effect. One of the upsides of using Varnish is that a less powerful and less expensive VPS package will accomplish the same job as a more high-priced one without the platform, so not only will your Internet sites perform significantly better, but you will also spare a certain amount of money.
Varnish in Dedicated Web Hosting
All dedicated web hosting which are ordered with the in-house built Hepsia website hosting Control Panel feature Varnish, which is one of the pre-installed software platforms that you’ll get with the dedicated machine. The Varnish content caching platform can be enabled and managed without any effort through Hepsia’s easy-to-use graphical interface and, with no more than one click, you can browse an elaborate log, add or reboot an instance, clear the cached data for any website and much, much more. Soon after you activate Varnish for a particular domain or sub-domain, it will start caching the webpages opened by your visitors and as soon as it has cached enough web content, you’ll observe a tremendously better site performance plus a reduced load. With Varnish-dedicated virtual memory starting at three gigabytes, you’ll be able to use the software platform for workload distribution purposes even if you run a huge number of websites on your machine.
