Varnish is a web accelerator tool, which has been gaining a lot in popularity in recent years, as it can increase the speed of any Internet site, at times even by 100%, depending on the content itself. This tool is sometimes called a caching HTTP reverse proxy as well and is used to lower the overall load on the physical server and to increase the browsing speed for the site visitors. Every time a visitor opens a page on a specific website, the web browser request is handled by the web server and the requested content is returned as a response. If the Varnish accelerator is enabled, it caches the pages that the website visitor browses and in case any of them is accessed for a second time, it’s delivered by Varnish and not by the server directly. The performance boost is due to the fact that the accelerator processes the browser requests significantly quicker than any web server, which results in much faster browsing speeds for the visitors. If any data is modified meanwhile, the cached pages will also be ‘refreshed’ the next time someone accesses them.
Varnish in Cloud Hosting
Varnish is available as an optional upgrade with all our Linux cloud plans. You can add it to your website hosting account via the Hepsia hosting Control Panel, which is available with all shared packages and you will get an exceptionally user-friendly interface, which will grant you full control over the data caching system. Using one-click quick-access controls, you can restart or deactivate any of the instances, in other words – Varnish will no longer be enabled for a given site. You can also see a comprehensive log file or erase the cache associated with any of the websites. When you add Varnish to your hosting package, you’ll be able to choose the maximum amount of system memory that will be available to you for data caching purposes and the number of the websites that will use Varnish. You can always order more memory in increments of 32 megabytes and, for best performance, you can get a dedicated IP address for the websites that will use Varnish. This will enable you to get the most out of your websites and to have plenty of pleased website visitors.
Varnish in Semi-dedicated Servers
The Varnish data caching platform is an essential part of the basic service set that you’ll get when you decide to host your sites in a semi-dedicated server account. You can enable it for any of your Internet sites through our next-gen Hepsia hosting Control Panel. The default amount of system memory that the Varnish platform can use to cache data is 64 MB, but if you decide that you need more, you can upgrade this amount of memory from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, i.e. the number of the sites that can use this platform at the same time. Since these two things are not linked to each other, you can use several sites with the default amount of memory or you can get more memory in increments of 32 megabytes and use all of it for a single site. The Varnish caching platform works best if you use a dedicated IP address for the websites that utilize its power. Hepsia will give you an easy way of rebooting any instance. Furthermore, you will be able to delete the cached data with just one single click of the mouse.
Varnish in VPS Servers
The Varnish data caching platform is included by default with all VPS servers offered by us on the condition that the virtual machine is ordered with the Hepsia hosting Control Panel, so you can optimize the performance of your sites with only a few mouse clicks. The more powerful the package, the more system memory Varnish will have at its disposal, but even with a lower-end plan, the caching platform will be able to utilize several hundred megabytes, so even if you manage a number of Internet sites, you will notice a serious decrease in the overall server load and a much faster webpage loading speed. The Varnish platform will have to work for a while as the users navigate the site and once the content has been cached, you will distinguish the effect. One of the pros of employing Varnish is that a lower-end and less pricey Virtual Private Server plan will accomplish the very same job as a more costly one without the platform, so not only will your Internet sites work considerably better, but you’ll also save some cash.
Varnish in Dedicated Servers
You can use Varnish to accelerate any site that’s hosted on a dedicated server from us when the Hepsia hosting Control Panel is pre-installed on the machine. Not only will you get the caching platform ready to be used at no additional cost, but you will also exert full control over it through the Hepsia Control Panel’s easy-to-navigate graphical interface. It will take just a click to start or delete an instance or to clear the cached data for any site that is using Varnish and if you’re more experienced, you can also check the platform’s logs. Varnish comes with no less than 3 GB of system memory for web content caching purposes, so even in case you host lots of sites on your machine and they all use the Varnish caching platform, the improvement in their performance will be distinguishable. You’ll simply need to wait for a little while until Varnish caches whatever content the site visitors browse on their end. The Varnish platform works best when the websites use a dedicated IP, but due to the fact that our servers come with 3 charge-free IPs, you’ll have all that you need.
