Varnish is a website accelerator platform, which caches content for the sake of faster access. It is occasionally called an HTTP reverse proxy too and it interacts between a web server and a browser. When a website visitor accesses a particular page, the content is requested by the browser, and then the web server processes this request and returns the requested data. If Varnish is enabled for a site, it will cache the pages on the first request and in case the visitor opens a cached page again, the data will be delivered by the caching platform instead of the web server. The improved load speed is an end result of the substantially faster response speed that the Varnish platform offers compared to any server software. At the same time, this doesn’t mean that the site visitors will continue seeing the exact same content over and over again, since any change on any of the pages is reflected in the content that the Varnish platform keeps in its system memory.

Varnish in Cloud Website Hosting

In case you host your sites in a cloud website hosting account with us, you’ll be able to activate Varnish with several clicks through your Control Panel. The caching platform is offered as an optional upgrade with all our packages and you can choose the number of the websites that will use it and the total amount of system memory that will be available for the cached data. The two upgradeable features in the Control Panel’s Upgrades section are the number of instances and the amount of system memory and they are not directly linked to each other, so you can decide if you need plenty of memory for one large-size site or less memory for multiple smaller ones. You can use the full potential of the Varnish platform if the sites use a dedicated IP address. Using the Control Panel, you can effortlessly start/reboot/delete an instance, delete the cached content independently for each website which uses the Varnish platform or see an in-depth system log file.

Varnish in Semi-dedicated Servers

The semi-dedicated hosting plans offered by us will permit you to use Varnish as soon as your new account has been opened, since the content caching platform is offered by default. 64 megabytes of system memory will be assigned to Varnish the moment your account is enabled, so you can make use of this workload balancing software as soon as your website has been built. In case you need more system memory, you can add 32 MB at a time from the Upgrades section of the Hepsia hosting Control Panel and it will be allocated to your semi-dedicated machine in an instant. 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 memory that you use, which goes to say that you’ll enjoy more versatility. The platform will noticeably reduce the load on the semi-dedicated server generated by your websites, so your site visitors can enjoy fast-loading pages. You will be able to manage the Varnish platform effortlessly via your Control Panel using quick-access buttons. You will be able to start/shut down any of the instances that you have, to clear the cache for any of your websites or to view system log files.

Varnish in VPS Servers

You can use Varnish with all our VPS server plans at no extra cost, as the caching platform is pre-installed and is available by default. The sole condition is that the server must be ordered with the Hepsia hosting Control Panel, through which you’ll be able to set up Varnish for any of your sites with only a few clicks. Each package comes with a different amount of memory for caching purposes, but you will have no less than several hundred MB, which is enough even for several regularly visited sites. Shortly after you enable Varnish, it will begin caching the content that your website visitors open, so you’ll notice the tremendously faster webpage load speeds and the less load on your virtual machine very soon. Varnish will allow you to use a less pricey virtual machine, as you won’t require that many resources to warrant the uninterrupted operation of your Internet sites even if you run large-sized Internet sites with many visitors. Best results are achieved if the Internet sites which use the Varnish caching platform use also a dedicated IP.

Varnish in Dedicated Servers

If you order a dedicated server with the Hepsia Control Panel, you will get Varnish at no extra cost and you will exert total control over it via an amazingly intuitive graphical interface – you’ll be able to start, to remove or to reboot an instance, to see an in-depth log, to clear the cached data associated with any Internet site and much more. The Varnish platform will have several GB of virtual memory at its disposal, so even if you’ve got resource-hungry websites with an immense number of visitors, you will notice the much faster website load times and the less load on your dedicated machine. This will happen shortly after you begin using the Varnish platform, since it will require some time to cache the website content that visitors browse. You can make the most of the platform’s potential if the websites that are using it also use a dedicated IP, but due to the fact that your server includes several IPs by default, you will not have to pay anything on top of the monthly fee for the server itself.
