Varnish is a web app accelerator tool, which has been gaining a lot in popularity in recent years, as it can increase the speed of any site, at times even by one hundred percent, based on the content itself. This tool is occasionally called an HTTP reverse proxy as well and is used to decrease the overall load on the physical server and to improve the browsing speed for the website visitors. Each time a visitor accesses a page on a given Internet site, the browser request is processed by the web server and the requested content is served as a reply. If the Varnish accelerator is activated, it caches the pages that the visitor opens and if any of them is opened once again, it is served by Varnish and not by the web server directly. The improvement in the performance comes from the fact that the accelerator handles the browser requests tremendously faster than any web server, which results in much faster browsing speeds for the users. If any content is edited meanwhile, the cached pages will also be updated the next time someone tries to access them.

Varnish in Shared Hosting

Varnish comes as an optional upgrade with all our shared hosting. You can add it to your website hosting account from the Hepsia hosting Control Panel, which is offered with all shared hosting packages and you will get a rather simple-to-work-with graphical interface, which will give you complete control over the data caching system. Using 1-click fast-access controls, you can restart or discontinue any of the instances, in other words – Varnish will no longer be enabled for a particular site. You can also see a detailed log file or clear the cache for any of the sites. When you add Varnish to your hosting package, you’ll be able to choose the total amount of system memory that will be at your disposal for data caching purposes and the number of the websites that will use Varnish. You can always order more memory in increments of 32 MB and, for optimum performance, you can allocate a dedicated IP to the websites that will use Varnish. This will allow you to take full advantage of your sites and to have plenty of satisfied website visitors.

Varnish in Semi-dedicated Hosting

Varnish is an essential part of the default service set that you’ll obtain if you choose to host your sites under a semi-dedicated server account. You can set it up for any of your sites through our avant-garde Hepsia Control Panel. The default memory that the Varnish caching platform can use to cache content is 64 megabytes, but in case you decide that you want 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 caching platform at the same time. As these two features aren’t tied to each other, you can use several websites with the default memory or you can order more memory in increments of 32 MB and use all of it for a single website. The Varnish platform works best if you allocate a dedicated IP address to the sites that utilize its power. The Hepsia Control Panel will provide you with an easy way of restarting any instance. Also, you will be able to delete the cached content with just a click.

Varnish in VPS

We provide Varnish with all Hepsia-managed Linux VPS services, so if you purchase a server with this Control Panel, you will be able to take advantage of the caching platform at no additional fee. Varnish can utilize different amounts of system memory for content caching purposes depending on the specific Virtual Private Server plan that you have chosen during the order process, but in any case, this amount will not be less than several hundred MB. This is quite enough to optimize the overall performance of a handful of frequently visited sites, so the faster website loading speeds and the less load on the VPS will be noticeable. The effect may not be detectable momentarily, since Varnish will need a certain amount of time to cache the website content that visitors access, but shortly after you enable it, you’ll perceive its full capacity. This platform will allow you to use a less powerful VPS server and to pay less money to get the very same performance you would get with a more powerful virtual machine without Varnish.

Varnish in Dedicated Hosting

If you order a dedicated server with the Hepsia Control Panel, you will obtain Varnish at no extra charge and you will have total control over it through a rather time and effort saving GUI – you will be able to start, to cancel or to restart an instance, to browse an in-depth log, to clear the cached content associated with any website and much, much more. The Varnish platform will have several GB of system memory at its disposal, so even if you have traffic-intensive websites with a lot of visitors, you’ll notice the substantially better website load times and the lowered load on the server. This will happen soon after you begin using the Varnish platform, as it will need some time to cache the web pages that visitors access. You can make the most of the platform’s potential if the sites that are using it use also a dedicated IP, but due to the fact that your dedicated server comes with a couple of IPs by default, you will not have to pay anything on top of your monthly charge for the server itself.
