Varnish is a web app accelerator tool, which has been gaining a lot of popularity lately, as it can increase the loading speed of any website, at times even by one hundred percent, based on the content itself. This tool is occasionally referred to as an HTTP reverse proxy as well and is used to reduce the overall load on the server and to boost the access speed for the site visitors. Anytime a visitor accesses a page on a given site, the browser request is handled by the web server and the requested info is served as a response. If Varnish is enabled, it caches the pages that the website visitor browses and if any of them is loaded once again, it is served by Varnish and not by the web server directly. The boost in the overall performance comes from the fact that the accelerator handles the browser requests considerably quicker than any web server, which results in much faster browsing speeds for the visitors. In case any content is modified in the meantime, the cached webpages will also be updated the next time someone attempts to open them.
Varnish in Hosting
You can unlock Varnish’s potential and boost your websites’ loading speed regardless of the hosting plan that you have selected and you can activate and configure the content caching platform with a couple of clicks of the mouse through the easy-to-work-with graphical interface offered by our avant-garde Hepsia Control Panel. During the process, 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 content will be cached, in other words – the amount of memory. The latter is offered in increments of 32 megabytes and is not linked to the number of instances, so you can order more instances with less memory and vice versa. In case you have lots of content on a specific website and you win many website visitors, more memory will guarantee you a better result. You may also consider using a dedicated IP for the websites that will use the Varnish platform. Hepsia will provide you with easy 1-click buttons for deactivating or rebooting any instance, for deleting the cache for each Internet site and for checking exhaustive system logs.
Varnish in Semi-dedicated Servers
The Varnish content caching platform is an essential part of the basic set of services that you will acquire if you choose to host your sites in a semi-dedicated server account. You can set it up for any of your sites via our cutting-edge Hepsia hosting Control Panel. The default memory that the Varnish caching platform can use to cache data is 64 MB, but if you decide that you need more, you can upgrade this memory from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, i.e. the number of the websites that can use this caching platform simultaneously. As these two features aren’t tied to each other, you can use several Internet sites with the default memory or you can get more memory in increments of 32 megabytes and use all of it for one single website. The Varnish caching platform performs best if you get a dedicated IP for the sites that utilize its power. Hepsia will give you a simple means of restarting any instance. In addition, you will be able to delete the cached contents with just one click.
Varnish in VPS Servers
The Varnish platform is included by default with all VPS servers that we are offering as long as the server is ordered with the Hepsia hosting Control Panel, so you can boost the overall performance of your websites with just a couple of clicks of the mouse. The more powerful the plan, the more memory will be available to Varnish, but even with a less powerful plan, the caching platform will be able to utilize several hundred megabytes, so even if you manage several different sites, you will notice a noticeable reduction in the overall server load and a significantly faster page loading speed. The platform will have to work for a while as the users navigate the site and as soon as the site content has been cached, you’ll perceive the effect. One of the pluses of employing Varnish is that a lower-end and less expensive VPS plan will accomplish the very same job as a more pricey one without the caching platform, so not only will your websites work much better, but you will also spare some cash.
Varnish in Dedicated Servers
If you want a powerful website hosting solution and you purchase one of the Linux dedicated servers that we offer, you can use the Varnish content caching platform to improve the work of your Internet sites at no additional charge as long as the dedicated machine is ordered with our next-gen Hepsia Control Panel. Its intuitive GUI will allow you to keep an eye on platform processes, to clear the cached data or to restart any instance with one mouse click. The smallest amount of system memory that Varnish can use to cache website content is 3 gigabytes, which is more than enough for a huge number of busy Internet sites, so your dedicated server will be able to handle an enormous system load while your visitors are enjoying a seamless browsing experience. As your server will come with several dedicated IPs, you will be able to make use of Varnish’s full potential.
