1. Stream Analytics for AI Insights with Pub/Sub

    Python

    In order to create a streaming analytics pipeline that can provide AI insights, you'll need to utilize several cloud services working in harmony. The typical flow involves ingesting real-time data into a messaging service such as Google Cloud Pub/Sub, processing it with a stream processing service like Google Dataflow, and possibly integrating it with AI services for insight generation.

    Below is a Pulumi program that sets up a simple streaming pipeline using Google Cloud Pub/Sub and Dataflow. The Pub/Sub service is used to create a topic for data ingestion and a subscription to pull messages for processing. The Dataflow service is used to create a job that could be linked to your custom streaming analytics and AI processing logic.

    Google Pub/Sub lets you create a scalable and flexible messaging pipeline, where you can publish and subscribe to data streams. On the other hand, Google Dataflow enables you to process that data stream with any arbitrary complexity of computation, possibly invoking AI models or analytics tools.

    Here is what the code does:

    1. Pub/Sub Topic: A topic is created to receive and distribute messages. In real-world use, producers will send messages to this topic.
    2. Pub/Sub Subscription: A subscription to the topic is created. It pulls messages for processing; in our case, it is the source that feeds into the Dataflow job.
    3. Dataflow Job: This is the processing engine that we set up. It will contain the logic to process messages from Pub/Sub and apply some analytics or AI insights generation. This code assumes you have a template_gcs_path which is a path to a Google Cloud Storage bucket where your Dataflow job template is stored and temp_location which is another GCS location used for storing temporary runtime files.

    Before starting, make sure you have the Google Cloud SDK properly set up and authenticated on your local machine along with Pulumi.

    Please refer to Pub/Sub Topic documentation, Pub/Sub Subscription documentation, and Dataflow Job documentation for more details.

    Below is the Pulumi Python program for setting up this streaming pipeline:

    import pulumi import pulumi_gcp as gcp # Create a Google Cloud Pub/Sub Topic pubsub_topic = gcp.pubsub.Topic('my-topic', # Optionally, you can add labels or other topic settings # labels={"environment": "production", ...} ) # Create a Google Cloud Pub/Sub Subscription to the Topic pubsub_subscription = gcp.pubsub.Subscription('my-subscription', topic=pubsub_topic.name, ) # Set up a Google Cloud Dataflow Job that consumes the Pub/Sub messages dataflow_job = gcp.dataflow.Job('streaming-analytics-job', template_gcs_path='gs://path-to-dataflow-template', # Replace with the path to your Dataflow template. temp_gcs_location='gs://path-to-temp-bucket', # Replace with the path to a GCS bucket for temporary files. parameters={ 'inputSubscription': pubsub_subscription.id.apply(lambda id: f'projects/my-gcp-project/subscriptions/{id}'), 'outputTable': 'my-bigquery-project:dataset.tableName', # Replace with your output destination }, max_workers=5, # Maximum number of workers to run the job. # Optionally, you can add additional Dataflow job settings such as labels, machine type, etc. ) # Export the URLs of the Pub/Sub and Dataflow resources pulumi.export('pubsub_topic_url', pubsub_topic.id) pulumi.export('pubsub_subscription_url', pubsub_subscription.id) pulumi.export('dataflow_job_url', dataflow_job.id)

    Each pulumi.export line at the end of the program provides links to the corresponding resources in the GCP console, making it easy for you to navigate and observe their configurations and statuses.

    After running this Pulumi program, you should have a scalable Pub/Sub topic to ingest data, a subscription that can be used by a consumer (such as Dataflow), and a Dataflow job template that will process the data according to your defined logic (such as applying machine learning models for AI insights).

    Beyond this, to truly build AI insights, you would need to implement the logic in the Dataflow job that applies your desired AI analytics, typically in the form of user-defined functions or transforms that interface with AI platforms or run machine learning models. This part depends heavily on your specific AI tools (like TensorFlow or Google AI Platform) and your business logic.
