BigQuery is optimized for analytical queries and may become costly if used purely for log storage without query requirements. Cloud Bigtable is suitable for semi-structured or time-series data requiring low-latency access, but is not as cost-effective for bulk archival storage. Cloud Storage allows enterprises to store logs in Standard, Nearline, Coldline, or Archive storage classes, depending on access frequency and retention policies, enabling cost optimization. Lifecycle management automates deletion or class transitions based on rules, reducing operational overhead and storage costs. IAM integration ensures secure access control for sensitive logs, while Cloud Logging and Monitoring provide visibility into storage usage and access patterns. Multi-regional or regional replication ensures high availability and durability. Enterprises can integrate Cloud Storage with Dataflow, Pub/Sub, or BigQuery for downstream processing, analytics, and reporting. Encryption at rest and in transit provides compliance with GDPR, HIPAA, and PCI DSS. Versioning allows historical logs to be retained or restored in case of accidental deletion. Monitoring dashboards help optimize storage cost and access patterns. Cloud Storage supports high-throughput uploads and streaming for real-time log ingestion from applications or IoT devices. By leveraging Cloud Storage, organizations achieve scalable, cost-efficient, durable log storage while retaining operational simplicity, security, and compliance. Automated management, lifecycle policies, and integration with analytics and monitoring tools provide enterprises with a comprehensive solution for log retention, analysis, and operational oversight. Cloud Storage abstracts infrastructure management, replication, scaling, and durability, enabling organizations to focus on analyzing logs rather than managing storage. The service provides predictable performance, cost optimization, operational simplicity, and enterprise-grade reliability for storing logs at scale, making it the preferred solution for log management in Google Cloud.
Question 225
A company wants to process batch and streaming IoT data with transformation and aggregation before loading it into analytics systems. Which service should be used?
A) Dataflow
B) Cloud Functions
C) Cloud Pub/Sub
D) Cloud Storage
Answer: A
Explanation:
Processing batch and streaming IoT data with transformation and aggregation before loading into analytics systems requires a service capable of real-time and batch processing at scale. Dataflow is a fully managed, serverless service designed for stream and batch data processing, enabling complex transformations, aggregations, and integration with analytics systems such as BigQuery. Cloud Functions provides serverless execution for event-driven tasks, but is limited in scalability and complex ETL pipelines. Cloud Pub/Sub provides messaging and event ingestion but does not perform transformations or aggregations natively. Cloud Storage stores raw data but lacks the processing capabilities required for transformation and aggregation. Dataflow allows enterprises to ingest IoT data from Pub/Sub, Cloud Storage, or external sources, apply real-time transformations, windowed aggregations, filtering, enrichment, and load processed data into BigQuery or other sinks for analytics. IAM integration ensures secure access to sources and sinks, while logging and monitoring provide operational visibility into pipeline performance, throughput, latency, and errors. Advanced features like event-time processing, session analysis, and watermarks enable the handling of late or out-of-order events reliably. Autoscaling ensures pipelines handle varying data volumes efficiently. Retry mechanisms and dead-letter topics improve pipeline reliability and data integrity. Dataflow pipelines can be versioned and tested for reproducibility, supporting MLOps or analytics workflows. Integration with monitoring dashboards allows teams to optimize throughput, latency, and operational efficiency. Enterprises benefit from reduced operational overhead, real-time insights, and scalable, serverless ETL for IoT and other streaming data. Dataflow abstracts infrastructure management, automatically provisioning resources, managing scaling, and ensuring high availability. It enables enterprises to focus on business logic, transformation rules, and analytics objectives without manual intervention. Dataflow provides a unified programming model for batch and streaming pipelines using Apache Beam SDKs. Integration with downstream analytics platforms enables near real-time insights, dashboards, and predictive modeling. By using Dataflow, organizations achieve reliable, scalable, serverless, and fault-tolerant processing of IoT data for analytics, improving operational efficiency, decision-making, and insight generation. It supports end-to-end ETL, stream processing, batch analytics, and integration with Google Cloud’s analytics ecosystem, making it the preferred choice for enterprises processing IoT and other streaming workloads.
