Creation and management of a multitude of webpages can be a lot of effort, either in a technical or in an organizational way. The editorial supervision of over forty websites with up to five languages alone can not be done along the way. Solutions that ease those pains on any level are gladly taken. This is one area of application that TYPO3 was designed for.
One TYPO3 instance is enough to serve lots of individual websites. Functionality, content, assets, templates and accounts can easily be shared across pages. And having an underlying architecture including redis and Varnish along with a central backup enable the needed power and security.
In a rather short timeframe, such a webpage cluster was created for ESG Edelmetall-Service GmbH & Co. KG. And with the TYPO3 Long Term Support there is enough planning reliability for future extensions in all directions.
