Varnish is a web accelerator tool, which has been gaining a lot of popularity lately, as it can increase the load speed of any website, sometimes even by 100 percent, based on the content. This tool is sometimes called an HTTP reverse proxy too and is used to decrease the overall server load and to increase the access speed for the site visitors. Whenever a visitor loads a page on a particular Internet site, the browser request is taken care of by the web server and the requested data is delivered as a response. If the Varnish accelerator is enabled, it caches the pages that the visitor opens and in case any of them is opened once again, it is delivered by Varnish and not by the server directly. The improvement in the performance comes from the fact that the accelerator processes the web requests substantially quicker than any web server, which leads to much faster browsing speeds for the site visitors. If any data is changed in the meantime, the cached pages will also be ‘refreshed’ the next time somebody opens them.
Varnish in Cloud Website Hosting
You can take advantage of Varnish’s potential and accelerate the load speed of your websites regardless of the cloud website hosting plan that you have chosen and you can enable and configure the data caching platform with a few clicks via the easy-to-work-with graphical interface offered by our avant-garde Hepsia hosting Control Panel. During the process, you’ll be able to select two different things – how many websites will use the Varnish caching platform, in other words – the number of instances, and how much data will be cached, i.e. the amount of system memory. The latter comes in increments of 32 megabytes and is not bound to the number of instances, so you can use more instances and less memory and the other way around. If you have a lot of content on a certain Internet site and you get lots of website visitors, more system memory will give you a better result. You may also consider using a dedicated IP address for the websites that will use the Varnish caching platform. Hepsia will provide you with simple 1-click controls for switching off or restarting any instance, for clearing the cache associated with any Internet site and for seeing detailed logs.
Varnish in Semi-dedicated Hosting
The Varnish caching platform is included in the standard service set that you’ll receive in case you decide to host your sites under a semi-dedicated server account. You can enable it for any of your sites via our cutting-edge Hepsia Control Panel. The default amount of system memory that Varnish can use to cache data is 64 MB, but in case you decide that you need more, you can upgrade this memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, in other words – the number of the Internet sites that can use this caching platform simultaneously. Since these two features aren’t linked to each other, you can use several Internet sites with the default amount of memory or you can get more memory in increments of 32 MB and use all of it for a single site. The Varnish caching platform works best when you use a dedicated IP address for the websites that utilize its power. The Hepsia Control Panel will offer you an easy means of rebooting any instance. Also, you will be able to delete the cached data with just a click.
Varnish in VPS
We offer Varnish with all of the Hepsia-managed Linux VPS packages, so in case you purchase a server with this hosting Control Panel, you will be able to make the most of the data caching platform at no extra fee. Varnish can utilize different amounts of system memory for data caching purposes based on the very VPS plan that you’ve chosen during the signup process, but at any rate, this amount will not be less than several hundred MB. This is quite enough to optimize the performance of several heavy Internet sites, so the better website browsing speeds and the less load on the virtual machine will be noticeable. The effect may not be observable instantly, since the Varnish platform will require a certain amount of time to cache the content that users request, but soon after you activate it, you will feel its full potential. This caching platform will permit you to use a lower-end Virtual Private Server and to give less money to get the exact same performance you would get with a more powerful virtual machine without Varnish.
Varnish in Dedicated Hosting
If you need the most powerful website hosting solution and you get any of the Linux dedicated servers hosting packages that we offer, you’ll be able to use the Varnish content caching platform to enhance the work of your Internet sites at no additional charge as long as the server is ordered with our leading-edge Hepsia Control Panel. Its user-friendly graphical interface will allow you to keep an eye on platform processes, to delete the cache or to restart any instance with one click. The minimal amount of memory that the Varnish caching platform can use to cache Internet site content is three gigabytes, which is more than enough for a huge number of large-sized sites, so your server will be able to cope with a huge load while your website visitors are having a smooth web browsing experience. Since your dedicated server will include several dedicated IP addresses, you will be able to make use of Varnish’s maximum potential.
