I was invited to speak at the R+V Talk4Nerds event in Frankfurt, to give 2 talks - one on Terraform and the other on Vault to an audience of around 100 people. Both talks were recorded and are available on Youtube.
My first talk of the day was on the use of Terraform to provision into multiple clouds, or more generally to deploy and config anything with an API.
I closed up the day with a talk on how Vault allows you to manage secrets and protect sensitive data.
For a moment of humour when disaster strikes, check out the Vault video around the 28 minute mark.
