🪣Google Cloud Storage

NEW

Also known as: GCS

A scalable, durable, secure object storage service on Google Cloud for storing and serving unstructured data.

DESCRIPTION

Google Cloud Storage (GCS) stores data as objects within globally accessible buckets. It offers multiple storage classes, lifecycle policies, versioning, and IAM-based security. GCS integrates with BigQuery, Dataproc, and Dataflow, powering data lakes and analytics pipelines. Data can be managed via gsutil, client SDKs, and console. Typical use cases include backups, media hosting, datasets, and pipeline staging. Competing services include Amazon S3 and Azure Blob Storage. Performance features include parallel uploads, composite objects, and regional selection.

TOP QUESTIONS

Why use Google Cloud Storage for data lakes?

It provides durable, scalable object storage with tight integration to BigQuery and Spark ecosystems.

Category: Benefits

How does GCS compare to Amazon S3?

Both offer similar object storage; GCS integrates natively with Google Cloud services, while S3 integrates across AWS.

Category: Comparison

How should you secure data in GCS?

Use IAM roles, bucket policies, encryption keys (CMEK), and audit logging; restrict public access.

Category: Best practices

What are common mistakes with GCS lifecycle policies?

Aggressive deletions without versioning can remove needed data; misaligned storage classes increase costs.

Category: Mistakes

How does GCS support performance at scale?

Parallel uploads, resumable transfers, and regional buckets help deliver throughput and low latency.

Category: Capabilities

What hot topics surround GCS?

Optimizing parquet-based lakehouse queries and cross-region replication strategies are active areas.

Category: Topic

What risks exist when using GCS?

Misconfigured access controls can expose data; lack of retention policies may cause accidental deletions.

Category: Risks

How do you manage GCS programmatically?

Use gsutil, client libraries, or REST APIs to create buckets, upload objects, and configure IAM.

Category: Management

Where should beginners start with GCS?

Create a bucket, upload sample data, set IAM roles, and try querying via BigQuery external tables.
