Learn about Varnish, understand more details on website accelerators and learn exactly what it is they do.
Varnish is a web app accelerator tool, which has been gaining a lot of popularity in recent years, because it can increase the speed of any Internet site, sometimes even by one hundred percent, based on the content. This tool is sometimes referred to as an HTTP reverse proxy too and is used to reduce the overall load on the physical machine and to accelerate the access speed for the website visitors. Anytime a visitor loads a page on a given site, the browser request is handled by the web server and the requested data is served as a response. If the Varnish accelerator is activated, it caches the web pages that the visitor opens and in case any of them is opened for a second time, it’s served by Varnish and not by the server directly. The improvement in the performance is due to the fact that the accelerator handles the browser requests tremendously quicker than any web server, which leads to much faster browsing speeds for the site visitors. In case any content is edited in the meantime, the cached pages will also be ‘refreshed’ the next time someone attempts to access them.
Varnish in Cloud Hosting
You can unlock Varnish’s potential and improve your sites’ speed regardless of the cloud hosting
package that you have chosen and you can enable and set up the content caching platform with a couple of clicks via the simple-to-use GUI offered by our avant-garde Hepsia hosting Control Panel. In the meantime, you’ll be able to choose two separate things – how many Internet sites will use Varnish, i.e. the number of instances, and how much data will be cached, i.e. 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 the other way around. In case you have a lot of content on a specific website and you draw numerous visitors, more memory will give you better results. You may also consider employing a dedicated IP address for the websites that will use the Varnish caching platform. Hepsia will offer you simple 1-click buttons for terminating or restarting any instance, for erasing the cache for each website and for seeing in-depth system logs.
Varnish in Semi-dedicated Servers
The semi-dedicated hosting plans
offered by our company will permit you to employ Varnish once your brand-new semi-dedicated server account has been opened, since the platform is available by default. 64 megabytes of system memory will be allocated to Varnish the second your account is enabled, so you can make use of this load balancing software as soon as your website has been published on the Internet. In case you need more memory, you can get 32 megabytes at a time from the Hepsia Control Panel’s Upgrades section and it will be allocated to your semi-dedicated machine in an instant. You can also increase the number of the Internet sites that use Varnish, or the so-called ‘instances’, which are not directly linked to the amount of system memory that you use, which means that you’ll enjoy more freedom. The Varnish caching platform will noticeably reduce the load on the semi-dedicated server produced by your websites, so your site visitors can enjoy fast-loading web pages. You will be able to manage the Varnish platform with ease through your Control Panel using fast-access buttons. You will be able to start/stop any of the instances that you’ve got, to clear the cached files for any of your Internet sites or to view system logs.
Varnish in VPS Servers
The Varnish content caching platform comes by default with all VPS hosting plans
that we offer as long as the VPS server is ordered with the Hepsia Control Panel, so you can optimize the performance of your sites with just a couple of clicks of the mouse. The more powerful the package, the more memory will be available to Varnish, but even with a less powerful plan, the platform will be able to utilize several hundred megabytes, so even if you own several different Internet sites, you’ll notice an enormous reduction in the server load and a significantly better page load speed. The Varnish caching platform will have to work for a little while as the visitors navigate the site and once the content has been cached, you’ll perceive the effect. One of the upsides of using Varnish is that a less powerful and less pricey plan will do the very same job as a more pricey one without the platform, so not only will your websites work substantially better, but you will also spare some cash.
Varnish in Dedicated Servers
You can use Varnish in order to improve the loading speed of any website that is hosted on a dedicated server
from our company if the Hepsia Control Panel is installed on it. Not only will you get the content caching platform ready for use at no additional fee, but you will also have full control over it via the Hepsia Control Panel’s intuitive graphical interface. It will take just one single mouse click to start or disable an instance or to clear the cached files for any website that’s using Varnish and if you are more advanced, you can also view the platform’s logs. Varnish comes with no less than 3 GB of system memory for data caching purposes, so even if you host lots of sites on your dedicated machine and they all use the Varnish platform, the difference in their performance will be obvious. You will only need to wait for a little while till Varnish caches whatever webpages the site visitors open on their end. The platform works best when the Internet sites use a dedicated IP address, but due to the fact that our dedicated servers include 3 free IPs, you will have all that you need.
