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 Internet site, sometimes even by one hundred percent, depending on the content. This tool is occasionally referred to as an HTTP reverse proxy as well and is used to decrease the overall load on the server and to increase the access speed for the site visitors. Anytime a visitor opens a page on a specific site, the browser request is processed by the web server and the requested info is sent as a response. If Varnish is activated, it caches the pages that the site visitor opens and in case any of them is loaded for a second time, it’s delivered by Varnish and not by the server directly. The boost in the performance 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 site visitors. If any data is edited in the meantime, the cached webpages will also be ‘refreshed’ the next time somebody attempts to access them.

Varnish in Cloud Website Hosting

Varnish comes as an optional upgrade with each of our Linux cloud website hosting plans. You can add it to your web hosting account from the Hepsia hosting Control Panel, which is offered with all shared hosting plans and you will get a rather simple-to-work-with interface, which will give you complete control over the content caching platform. Using 1-click fast-access controls, you can reboot or stop any of the instances, i.e. Varnish will no longer be enabled for a given website. You can also see an elaborate log or clear the cache for any of the Internet sites. When you add Varnish to your web hosting package, you’ll be able to choose the maximum amount of system memory that will be at your disposal for content caching purposes and the number of the sites that will use Varnish. You can always add more memory in increments of 32 MB and, for optimal performance, you can allocate a dedicated IP address to the sites that will use Varnish. This will allow you to get the most out of your Internet sites and to have many pleased website visitors.

Varnish in Semi-dedicated Servers

The Varnish platform is included in the basic set of services that you will obtain if you decide to host your sites under a semi-dedicated server account. You can enable it for any of your websites through our next-gen Hepsia Control Panel. The default system memory that the Varnish platform can use to cache data is 64 megabytes, but if you decide that you want 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 Internet sites that can use this caching platform at the same time. As these two features aren’t linked to each other, you can use a few websites with the default amount of memory or you can add more memory in increments of 32 MB and use all of it for a single web site. Varnish performs best if you get a dedicated IP address for the sites that utilize its power. Hepsia will give you a simple way of restarting any instance. Furthermore, you’ll be able to clear the cached files with only one single click.

Varnish in VPS Servers

You can use the load balancing potential of Varnish with each of our Linux VPS servers when you pick Hepsia as your hosting Control Panel. The Varnish caching platform is available by default and the memory that it’ll be able to use to cache your site content is dependent upon the particular plan that you have selected, but even with the less powerful plans, you’ll have no less than several hundred megabytes of system memory at your disposal only for caching purposes. This amount is sufficient enough to enhance the work of multiple websites. It will take a little time for you to observe the results, as the Varnish platform caches the content that website visitors open, but shortly thereafter you will notice the substantially reduced load on your virtual machine and the accelerated Internet site browsing speed. The Varnish caching platform will permit you to use a less powerful plan for websites that would typically require a more high-priced web hosting service.

Varnish in Dedicated Servers

If you order a dedicated server with the Hepsia Control Panel, you will acquire the Varnish platform at no additional cost and you’ll exert total control over it via a very intuitive graphical interface – you will be able to start, to delete or to restart an instance, to check an exhaustive log, to clear the cache for any Internet site and much more. Varnish will have several GB of memory at its disposal, so even if you have large-scale sites with lots of visitors, you will notice the significantly better web page loading times and the lowered load on the dedicated server. This will happen shortly after you begin using Varnish, as it will need some time to cache the pages that visitors access. You can make the most of the platform’s capability if the websites that are using it use also a dedicated IP address, but considering the fact that your dedicated server includes a couple of IPs by default, you won’t need to pay anything on top of the monthly fee for the machine itself.
