Lesson 1 Architecting ML Solutions with Vertex AI
The Google Cloud Professional Machine Learning Engineer exam validates the ability to design, build, and operate production ML systems on Google Cloud. Vertex AI is the central platform: it provides training jobs, AutoML, the Model Registry, endpoints, pipelines, experiments, Feature Store, and Vector Search. Architects choose the right mix of managed services, define reproducible pipelines, and separate concerns such as experiment tracking, model versioning, and prediction serving. Feature Store provides online and offline feature serving, Model Garden offers curated models, and TensorBoard helps teams compare training runs. A well-designed architecture balances performance, cost, security, and operational ownership.
Example
Example: A team uses Vertex AI Pipelines, Experiments, Feature Store, and an endpoint to move a recommendation model from experiment to production reproducibly.Lesson 2 Building High-Performance Data Pipelines
High-performance ML depends on data pipelines that transform raw data reliably at scale. BigQuery provides SQL analytics and BigQuery ML, Dataflow unifies stream and batch processing, Pub/Sub ingests real-time events, and Cloud Storage stores training artifacts. Dataproc runs Spark workloads such as feature engineering, while Cloud Composer orchestrates scheduled workflows. BigQuery reservations and slot autoscaling control query capacity and cost. Vertex AI Datasets version labeled training data, and Dataflow templates make pipelines repeatable. Select storage and processing based on latency, volume, cost, and freshness requirements.
Example
Example: A streaming fraud feature pipeline reads events from Pub/Sub, transforms them with Dataflow, stores features in Feature Store, and serves them to an online endpoint.Lesson 3 Training and Serving Models on Vertex AI
Vertex AI supports both custom and automated model training. Custom training jobs run your own containers, AutoML trains models with minimal code, and hyperparameter tuning searches for the best settings. Vizier powers black-box optimization, Explainable AI produces feature attributions, and specialized services such as Forecast handle time-series problems. Custom prediction containers give you full control over serving. Models are stored in the Model Registry and deployed to endpoints with traffic splits for staged rollout. Choose training approaches by data type, model complexity, and team skills.
Example
Example: A team trains a custom container with hyperparameter tuning, registers the best version, and rolls it out with a 10 percent traffic split.Lesson 4 Scalability, Security and Compliance
Production ML must scale predictably and protect data. Vertex AI endpoints use min and max replica counts plus autoscaling to absorb traffic, while batch prediction handles large offline workloads. GPU and TPU quotas control accelerator availability, and BigQuery slot autoscaling adjusts analytics capacity. Security combines VPC Service Controls perimeters, Cloud KMS customer-managed keys, private endpoints, and least-privilege service accounts. Cloud DLP de-identifies sensitive data before training, and Confidential VMs protect data in use. Design for cost, latency, and compliance together.
Example
Example: An endpoint uses minReplicaCount 2 and maxReplicaCount 10, while VPC Service Controls and a private endpoint keep prediction traffic inside the organization.Lesson 5 MLOps, Monitoring and Governance
MLOps keeps models reliable and governed after release. Vertex AI Model Monitoring detects training-serving skew and data drift, and the Model Registry manages versions and aliases for staged rollout. Pipelines caching skips unchanged steps while Experiments and Metadata record artifacts and lineage. Cloud Logging collects audit and operational logs, and continuous training retrains models as new data arrives. Define alerting, rollback, retention, and reproducibility policies so every model is observable and auditable.
