Varnish is a web application accelerator, which has been gaining a lot of popularity in recent years, because it can increase the speed of any website, at times even by one hundred percent, depending on the content. This tool is occasionally called a caching HTTP reverse proxy as well and is used to decrease the overall load on the server and to enhance the browsing speed for the site visitors. Every time a visitor loads a page on a given website, the web browser request is taken care of by the web server and the requested data is delivered as a response. If Varnish is activated, it caches the pages that the website visitor opens and if any of them is accessed once again, it is fetched by Varnish and not by the server directly. The increase in the overall performance is due to the fact that the accelerator handles the web requests considerably quicker than any web server, which results in much faster browsing speeds for the users. In case any data is changed in the meantime, the cached web pages will also be updated the next time someone accesses them.

Varnish in Web Hosting

Varnish comes as an optional upgrade with each of our Linux web hosting. You can add it to your website hosting account through the Hepsia Control Panel, which is offered with all shared web hosting packages and you will get a quite user-friendly GUI, which will grant you complete control over the content caching system. Using 1-click fast-access controls, you can reboot or disable any of the instances, i.e. Varnish will no longer be enabled for a particular site. You can also check an in-depth log or clear the cache associated with any of the sites. When you add Varnish to your shared web hosting package, you’ll be able to select the maximum amount of memory that will be available to you for content 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 top performance, you can assign a dedicated IP to the websites that will use Varnish. This will allow you to take full advantage of your Internet sites and to have numerous pleased website visitors.

Varnish in Semi-dedicated Hosting

Varnish is part of the basic set of services that you’ll receive when you choose to host your Internet sites in a semi-dedicated server account. You can activate it for any of your sites via our next-generation 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 memory from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, in other words – the number of the websites that can use this caching platform simultaneously. Since these two features are not bound to each other, you can use several instances with the default amount of memory or you can get more memory in increments of 32 MB and use all of it for a single web site. The Varnish caching platform works best if you allocate a dedicated IP address to the websites that utilize its power. Hepsia will provide you with a simple way of rebooting any instance. In addition, you’ll be able to clear the cached contents with only a click.

Varnish in VPS Web Hosting

The Varnish data caching platform is included by default with all Linux VPS web hosting offered by our company on the condition that the virtual server is ordered with the Hepsia hosting Control Panel, so you can enhance the work of your websites with only a few mouse clicks. The more powerful the plan, the more 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 run several different Internet sites, you will notice a great decrease in the overall server load and a tremendously better site load speed. The Varnish caching platform will need to work for a while as the visitors browse the site and as soon as the website content has been cached, you will distinguish the effects. One of the benefits of using Varnish is that a lower-end and less expensive package will accomplish the same job as a more expensive one without the platform, so not only will your websites perform considerably better, but you’ll also save some money.

Varnish in Dedicated Servers Hosting

In case you order a dedicated server with the Hepsia Control Panel, you’ll acquire the Varnish data caching platform at no extra fee and you will exert full control over it via an incredibly time and effort saving graphical interface – you will be able to start, to terminate or to reboot an instance, to view an exhaustive system log, to clear the cache associated with any website and much, much more. The Varnish caching platform will have several GB of memory at its disposal, so even if you have busy Internet sites with a huge number of visitors, you’ll notice the substantially faster web page loading times and the lowered load on the dedicated server. This will happen shortly after you begin using the Varnish platform, since it will require a certain amount of time to cache the site content that users open. You can make the most of the platform’s capacity in case the sites that are using it also use a dedicated IP address, but since your server includes a few IPs by default, you won’t have to pay anything on top of the monthly charge for the server itself.
