Varnish is a web app accelerator tool, which has been gaining a lot in popularity in recent years, as it can increase the load speed of any Internet site, at times even by one hundred percent, based on the content itself. This tool is occasionally referred to as a caching HTTP reverse proxy as well and is used to lower the overall load on the physical machine and to improve the access speed for the website visitors. Whenever a visitor accesses a page on a certain Internet site, the web browser request is taken care of by the web server and the requested content is sent as a response. If the Varnish accelerator is enabled, it caches the pages that the website visitor opens and if any of them is accessed once again, it is served by Varnish and not by the web server directly. The boost in the performance is due to the fact that the accelerator processes the web requests significantly quicker than any web server, which results in much faster browsing speeds for the website visitors. If any data is changed meanwhile, the cached web pages will also be updated the next time someone accesses them.

Varnish in Cloud Hosting

You can use Varnish’s full potential and optimize your websites’ load speed regardless of the cloud hosting package that you’ve picked and you can enable and configure the content caching platform with a few clicks of the mouse using the user-friendly GUI offered by our advanced Hepsia Control Panel. In the meantime, you’ll be able to select two different things – how many websites will use the Varnish caching platform, i.e. the number of instances, and how much info will be cached, i.e. the amount of system memory. The latter is available in increments of 32 MB and is not tied to the number of instances, so you can order more instances and less memory and the other way around. If you’ve got lots of content on a specific website and you attract plenty of site visitors, more system memory will give you better results. You may also consider employing a dedicated IP address for the Internet sites that will use Varnish. The Hepsia Control Panel will provide you with easy 1-click controls for terminating or restarting any instance, for erasing the cache associated with any site and for seeing comprehensive logs.

Varnish in Semi-dedicated Servers

The Linux semi-dedicated hosting service offered by us will allow you to use Varnish once your new account has been activated, since the caching platform comes by default. 64 megabytes of system memory will be assigned to Varnish the second your account is enabled, so you can use this workload distribution software once your website has been published to the web. In case you’re in need of more system memory, you can get 32 MB at a time from the Upgrades section of the Hepsia Control Panel and it will be allocated to your semi-dedicated server in a flash. You can also increase the number of the sites that use Varnish, or the so-called ‘instances’, which are not bound directly to the amount of system memory that you use, which goes to say that you’ll have more versatility. The platform will greatly lower the load on the semi-dedicated server that your websites cause, so your site visitors can enjoy fast-opening pages. You’ll be able to manage the Varnish caching platform effortlessly via the Control Panel using quick-access buttons. You’ll be able to start/delete any of the instances that you’ve got, to clear the cached data associated with any of your websites or to view system log files.

Varnish in VPS Servers

Varnish comes by default with all Linux VPS service that we are offering given that the machine is ordered with the Hepsia hosting Control Panel, so you can boost the performance of your sites with only a few clicks. The more powerful the package, the more memory will be available to Varnish, but even with a lower-end package, the platform will be able to utilize several hundred MB, so even if you manage several Internet sites, you’ll notice an enormous decrease in the overall server load and a significantly better webpage load speed. The Varnish platform will need to work for a while as the visitors navigate the site and as soon as the website content has been cached, you will observe the effects. One of the pros of employing Varnish is that a less powerful and less costly package will do the very same job as a more expensive one without the platform, so not only will your sites perform significantly better, but you will also spare some cash.

Varnish in Dedicated Servers

In case you order a dedicated server with the Hepsia hosting Control Panel, you will acquire Varnish at no additional charge and you will have complete control over it via an incredibly simple-to-work-with GUI – you’ll be able to start, to deactivate or to restart an instance, to see an exhaustive log, to clear the cached files associated with any website and much more. The Varnish platform will have several GB of system memory at its disposal, so even if you run resource-absorbing sites with a huge number of visitors, you will notice the tremendously faster page loading times and the less load on the dedicated server. This will happen shortly after you begin using Varnish, as it will need some time to cache the site 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 due to the fact that your server includes a couple of IPs by default, you won’t have to pay anything on top of the monthly fee for the machine itself.
