Learn precisely what Varnish is. Get to know more about web accelerators and their role.
Varnish is a web application accelerator tool, which has been gaining a lot in popularity in recent years, because it can increase the load speed of any website, at times even by 100 percent, based on the content itself. This tool is sometimes called a caching HTTP reverse proxy too and is used to decrease the overall server load and to boost the browsing speed for the website visitors. Anytime a visitor accesses a page on a particular Internet site, the web browser request is taken care of by the web server and the requested information is served as a response. If Varnish is activated, it caches the pages that the site visitor browses and if any of them is loaded once more, it’s fetched by Varnish and not by the web server directly. The performance improvement comes from the fact that the accelerator handles the web requests substantially quicker than any web server, which results in much faster browsing speeds for the users. If any data is updated meanwhile, the cached webpages will also be ‘refreshed’ the next time someone tries to open them.
Varnish in Shared Website Hosting
Our company offers Varnish as an optional upgrade with each and every shared website hosting plan
and if you would like to use it, you can add it to your web hosting account using the Upgrades menu in your Hepsia hosting Control Panel. There are two different features that can be upgraded – the instances and the system memory. The first one refers to the number of the websites that you want to employ Varnish for and the second one, which is available in increments of 32 MB, indicates the maximum amount of data that the data caching platform can store at any given moment. Hepsia’s user-friendly graphical interface will allow you to shut down or to restart any instance, to check in-depth logs or to erase the platform’s cache with just one click. For optimal results, you can use a dedicated IP for the websites that will use the caching platform. With Varnish, your Internet site will open considerably faster, meaning more satisfied website users and prospective customers.
Varnish in Semi-dedicated Servers
The Varnish content caching platform is part of the standard service set that you’ll get in case you choose to host your sites in a semi-dedicated server
account. You can activate it for any of your sites through our advanced Hepsia Control Panel. The default amount of 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 amount from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, i.e. the number of the websites that can use this platform simultaneously. Since these two features aren’t linked to each other, you can use a couple of Internet sites with the default amount of memory or you can order more memory in increments of 32 megabytes and use all of it for a single Internet site. The Varnish platform works best when you allocate a dedicated IP address to the sites that utilize its power. Hepsia will offer you an easy means of rebooting any instance. Also, you will be able to clear the cached content with just one single click.
Varnish in VPS Servers
You can take full advantage of the workload balancing capabilities of Varnish with any of our Linux VPS plans
in case you choose Hepsia as your hosting Control Panel. The data caching platform is available by default and the amount of memory that it will be able to use to cache the content of your websites depends on the particular Virtual Private Server plan that you have selected, but even with the lower-end plans, you will have no less than several hundred MB of system memory at your disposal only for caching purposes. This amount is sufficient to boost the work of numerous Internet sites. It will take some time for you to see the results, since the Varnish platform caches the content that site visitors open, but after that you’ll notice the substantially reduced load on the virtual machine and the increased site browsing speed. The Varnish platform will allow you to make use of a less powerful plan for sites which would normally need a more costly web hosting solution.
Varnish in Dedicated Servers
In case you order a dedicated server
with the Hepsia Control Panel, you will obtain the Varnish caching platform at no extra cost and you will have full control over it through a pretty time and effort saving graphical interface – you’ll be able to start, to delete or to reboot an instance, to check a comprehensive log, to delete the cached files associated with any Internet site and much more. The Varnish platform will have several GB of system memory at its disposal, so even if you manage traffic-heavy websites with a lot of visitors, you will notice the significantly faster web page loading speeds and the reduced load on the machine. This will happen shortly after you begin using the Varnish platform, as it will need a certain amount of time to cache the web pages that users browse. You can make the most of the platform’s capability if the websites that are using it also use a dedicated IP, but owing to the fact that your dedicated server comes with several IPs by default, you will not have to pay anything on top of your monthly fee for the server itself.
