What clouds are made of – EA data integration for cloud migration

What clouds are made of – EA data integration for cloud migration

Hermes recently switched to Google as their new strategic cloud provider. Following their Cloud Strategy, they wanted to use this opportunity to evolve their applications to the next level, instead of “just” doing a lift&shift – in a timeframe of six months. Everybody knew this would be ambitious – but did anyone know how complex it would be?

In this talk we will show you, how the Hermes EA team supported the cloud migration and illustrate how LeanIX data integration can be used to form a cloud that fits the strategy.
