Learn precisely what Varnish is. Discover more about web accelerators and their role.
Varnish is a website accelerator tool, which has been gaining a lot of popularity in recent years, because it can increase the speed of any site, at times even by one hundred percent, depending on the content itself. This tool is occasionally called a caching HTTP reverse proxy too and is used to lower the overall server load and to enhance the browsing speed for the site visitors. Every time a visitor opens a page on a given Internet site, the web browser request is handled by the web server and the requested info is sent as a response. If Varnish is enabled, it caches the web pages that the visitor opens and if any of them is opened for a second time, it’s served by Varnish and not by the web server directly. The performance improvement is due to the fact that the accelerator handles the browser requests substantially quicker than any web server, which leads to much faster browsing speeds for the users. In case any content is updated in the meantime, the cached web pages will also be updated the next time somebody opens them.
Varnish in Cloud Hosting
Varnish is offered as an optional upgrade with each Linux cloud hosting service
and if you wish to use it, you can add it to your web hosting account using the Upgrades section in your Hepsia Control Panel. There are two separate features that can be upgraded – the instances and the system memory. The first one pertains to the number of the websites that you would like to employ Varnish for, whereas the second, which is offered in increments of 32 MB, shows the total amount of data that the platform can store at any particular time. The Hepsia Control Panel’s simple-to-use GUI will permit you to remove or to reboot any instance, to view in-depth system logs or to erase the platform’s cache with just click of the mouse. For optimal results, you can employ a dedicated IP for the sites that will use the platform. With Varnish, your Internet site will open considerably faster, which means more satisfied visitors and prospective customers.
Varnish in Semi-dedicated Servers
All our semi-dedicated service
come with Varnish by default, so you can make use of the web app accelerator and accelerate the load speed of any site that you host on our semi-dedicated servers. You’ll get 64 megabytes of system memory dedicated to the Varnish accelerator at no additional charge and you can activate an instance with no more than a couple of clicks of the mouse through the Hepsia Control Panel, which is included with the semi-dedicated plans. If you need more memory, the latter is available in increments of 32 megabytes through the Control Panel’s Upgrades section and it will be available to you straight away. You can also order more instances as a separate upgrade, so you can choose if plenty of data will be cached for a single website or if the memory will be used by multiple websites. Hepsia will enable you to restart or to discontinue any instance, to check the system log associated with it or to clear the cached data using one-click buttons. To take full advantage of the Varnish accelerator, you can allocate a dedicated IP to the sites that will use it.
Varnish in VPS Servers
The Varnish data caching 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 improve the performance of your sites with just a few clicks of the mouse. The more powerful the plan, the more system memory Varnish will have at its disposal, but even with a low-end package, the caching platform will be able to utilize several hundred MB, so even if you’ve got a number of sites, you’ll notice a substantial reduction in the server load and a considerably faster web page load speed. The Varnish platform will need to work for a little while while the users browse the website and once the content has been cached, you will notice the result. One of the pros of employing Varnish is that a lower-end and less expensive package will accomplish the exact same job as a more high-priced one without the caching platform, so not only will your sites work much better, but you’ll also save some cash.
Varnish in Dedicated Servers
If you order a dedicated server
with the Hepsia Control Panel, you will acquire the Varnish content caching platform at no additional fee and you will have full control over it via an extremely simple-to-use interface – you’ll be able to start, to remove or to reboot an instance, to view an exhaustive log, to clear the cached files for any site and much, much more. The Varnish platform will have several GB of system memory at its disposal, so even if you manage resource-swallowing websites with plenty of visitors, you will notice the considerably faster web page loading times and the decreased load on the dedicated machine. This will become a fact soon after you start using the Varnish platform, since it will require some time to cache the website content that users browse. You can take full advantage of the platform’s potential if the sites that are using it use also a dedicated IP address, but since your dedicated server includes a couple of IPs by default, you won’t have to pay anything on top of the monthly fee for the server itself.
