The document discusses strategies for succeeding in an AI journey using Keras deep learning on cloud. It recommends starting with TensorFlow 2.0 and Keras in Google Colab for easy prototyping without setup. The strategy includes iterating on models, performing deep distributed training using cloud GPUs/TPUs, and serving models online/offline. Keras supports multiple backends like TensorFlow, CNTK, and MXNet to avoid lock-in to a single ecosystem.
