Varnish is a web app accelerator platform, which caches information for quicker response times. It is sometimes called a caching HTTP reverse proxy as well and it interacts 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 request and returns the requested data. If Varnish is enabled for a specific website, it will cache the pages on the first request and if the visitor visits a cached page again, the info will be delivered by the accelerator platform instead of the web server. The increased speed is an end result of the much faster response time that the Varnish platform offers as compared with any server software. At the same time, this doesn’t mean that the users will continue being served the very same content over and over again, since any change on any of the web pages is reflected in the content that Varnish caches in its system memory.
Varnish in Shared Hosting
You can make use of Varnish’s potential and boost the load speed of your sites irrespective of the shared hostingpackage that you’ve selected and you can activate and configure the platform with several mouse clicks via the simple-to-work-with GUI offered by our next-generation Hepsia Control Panel. In the meantime, you will be able to choose two different things – how many sites will use the Varnish platform, in other words – the number of instances, and how much data will be cached, in other words – the amount of memory. The latter is offered in increments of 32 MB and is not tied to the number of instances, so you can use more instances and less memory and vice versa. If you have plenty of content on a certain site and you receive lots of visitors, more memory will guarantee you better results. You may also consider employing a dedicated IP address for the sites that will use Varnish. The Hepsia Control Panel will provide you with simple one-click buttons for stopping or restarting any instance, for deleting the cache associated with each Internet site and for seeing in-depth system logs.
Varnish in Semi-dedicated Hosting
The semi-dedicated hosting that we offer will permit you to use Varnish as soon as your new account is active, as the data caching platform is offered by default. 64 megabytes of system memory will be allocated to Varnish the second your account is enabled, so you can take advantage of this workload distribution software once your website has been published on the Internet. In case you’re in need of more system memory, you can order 32 megabytes at a time from the Hepsia Control Panel’s Upgrades section and it will be allocated to your semi-dedicated machine momentarily. You can also increase the number of the sites that use Varnish, or the so-called ‘instances’, which are not linked directly to the amount of system memory that you use, which suggests that you’ll have more flexibility. The caching platform will immensely decrease the load on the semi-dedicated machine that your websites produce, so your site visitors can enjoy fast-opening pages. You’ll be able to manage Varnish without any effort through your Hepsia Control Panel using fast-access controls. You will be able to start/stop any of the instances that you’ve got, to clear the cached content for any of your sites or to see system logs.
Varnish in VPS Hosting
The Varnish caching platform is included by default with each of theVPS hosting that we are offering on the condition that the Virtual Private Server is ordered with the Hepsia Control Panel, so you can enhance the performance of your websites with just a few clicks. The more powerful the package, the more memory will be available to Varnish, but even with a lower-end plan, the caching platform will be able to utilize several hundred MB, so even if you’ve got several sites, you’ll notice an immense reduction in the server load and a tremendously faster page load speed. The Varnish caching platform will have to work for a little while as the users browse the pages and once the site content has been cached, you will notice the result. One of the pluses of employing Varnish is that a less powerful and less expensive Virtual Private Server package will accomplish the same job as a more pricey one without the platform, so not only will your sites work significantly better, but you’ll also spare some cash.
