1. Introduction to GCP Vertex AI

Vertex AI is Google Cloud Platform’s (GCP) unified machine learning (ML) platform that simplifies the process of building, deploying, and scaling ML models. It integrates various ML tools into a cohesive environment, enabling data scientists, ML engineers, and developers to manage the entire ML lifecycle efficiently.

Before Vertex AI, GCP had multiple services like AI Platform, AutoML, and TensorFlow on GCP. Vertex AI consolidates these services, providing a unified interface for model training, deployment, monitoring, and more.

Key benefits include:

• End-to-end ML lifecycle management
• Integration with other GCP services (BigQuery, Dataflow, Pub/Sub)
• Support for custom models and AutoML
• Scalable infrastructure with GPU/TPU support
