Just returning from an internal Amazon Connect deep[1] dive. I haven’t touched this particular product since maybe 5 years?! Dirk Fröhner — I’m sure you remember our joint large-scale workshop with one of your customers.

What stuck with me from that time was how fast you can actually set up a contact center in the cloud — less than 30 minutes from zero to the first call received — and how much AI was already improving both the customer and agent experience back then. That hasn’t changed.

🚀 Caught up on AWS’s open-sourcing of API models in Smithy format (slipped my radar earlier this year, but timeless value!). There is a GitHub Repository [4] available with AWS API smithy models for 200+ services. Announcement Blog: [1]

A Smithy model is the core semantic representation in Smithy, an open-source interface definition language (IDL) developed by AWS for defining APIs, services, and data structures in a protocol-agnostic way.

It consists of shapes (like primitives, lists, maps, structures, and services), traits for metadata, and shape IDs for referencing components, enabling code generation for SDKs, documentation, and validation across languages. Models are serialized in formats like Smithy IDL or JSON and include a prelude with built-in types.

Always takes a customer - my first time in our brand new BER21 in Berlin. Amazing location and Berlin is welcoming us with crispy & bright sunshine.

Always great to (re-) connect with colleagues. Bumping into Sascha to hear the latest about Containers at AWS, strategizing with Kerstin & Alexander and turning the last knobs with John on our presentation for this afternoon.

Wouldn’t be Berlin without the Bear obviously ….

“Good Morning!" said Bilbo, and he meant it. The sun was shining, and the grass was very green. But Gandalf looked at him from under long bushy eyebrows that stuck out further than the brim of his shady hat.

“What do you mean?” he said. “Do you wish me a good morning, or mean that it is a good morning whether I want it or not; or that you feel good this morning; or that it is a morning to be good on?”

This could have been a good new year’s resolution: Don’t make funny prediction about the future if you’re not ready to deal with them becoming true 😃.

On my way to:
