You can have the data safely on-prem, connected to computers that are connected to the internet, or safely in the cloud, connected to computers that are connected to the internet. The threats are not that different.

Managing product data on the cloud does not mean public internet access, unless someone messes something up big time.

> Airbus is putting all its design on internet? wow...

Not only Airbus. You see, cloud is secure, information is encrypted and only you have access to your data.

You'd be fooling yourself if you think any moderately complex company still hasn't moved to the cloud or isn't thinking about it (with rare exceptions)
