Cloud Storage

1. Storage Classes

graph LR STANDARD["Standard Storage"] NEARLINE["Nearline Storage"] COLDLINE["Coldline Storage"] ARCHIVE["Archive Storage"] STANDARD -->|30+ days| NEARLINE NEARLINE -->|90+ days| COLDLINE COLDLINE -->|365+ days| ARCHIVE classDef hot fill:#4285f4,stroke:#666,stroke-width:2px,color:#fff classDef warm fill:#34a853,stroke:#666,stroke-width:2px,color:#fff classDef cold fill:#fbbc05,stroke:#666,stroke-width:2px,color:#fff classDef archive fill:#ea4335,stroke:#666,stroke-width:2px,color:#fff class STANDARD hot class NEARLINE warm class COLDLINE cold class ARCHIVE archive

2. Bucket Configuration

# Create a bucket gsutil mb -l us-central1 gs://my-bucket # Set storage class gsutil defstorageclass set NEARLINE gs://my-bucket # Enable versioning gsutil versioning set on gs://my-bucket # Set lifecycle policy cat > lifecycle.json << EOF { "rule": [ { "action": {"type": "SetStorageClass", "storageClass": "NEARLINE"}, "condition": {"age": 30} } ] } EOF gsutil lifecycle set lifecycle.json gs://my-bucket

Cloud SQL

1. Instance Setup

# Create Cloud SQL instance gcloud sql instances create my-instance \ --database-version=MYSQL_8_0 \ --tier=db-f1-micro \ --region=us-central1 \ --root-password=my-password # Create database gcloud sql databases create my-database \ --instance=my-instance # Configure backup gcloud sql instances patch my-instance \ --backup-start-time=23:00 \ --enable-bin-log

2. High Availability Configuration

# high-availability.yaml settings: tier: db-n1-standard-2 availabilityType: REGIONAL backupConfiguration: enabled: true startTime: "23:00" location: us-central1 ipConfiguration: requireSsl: true databaseFlags: - name: "max_connections" value: "1000"

Cloud Spanner

1. Instance Configuration

# Create Spanner instance gcloud spanner instances create my-instance \ --config=regional-us-central1 \ --description="My Spanner Instance" \ --nodes=1 # Create database gcloud spanner databases create my-database \ --instance=my-instance

2. Schema Definition

-- Create table with interleaved structure CREATE TABLE Singers ( SingerId INT64 NOT NULL, FirstName STRING(1024), LastName STRING(1024), BirthDate DATE, ) PRIMARY KEY (SingerId); CREATE TABLE Albums ( SingerId INT64 NOT NULL, AlbumId INT64 NOT NULL, AlbumTitle STRING(1024), ReleaseDate DATE, ) PRIMARY KEY (SingerId, AlbumId), INTERLEAVE IN PARENT Singers ON DELETE CASCADE;

Firestore

1. Data Model

// Collection structure const userRef = db.collection('users').doc('user123'); const orderRef = userRef.collection('orders').doc('order456'); // Document structure const userData = { name: 'John Doe', email: 'john@example.com', metadata: { createdAt: Timestamp.now(), lastLogin: Timestamp.now() }, orders: ['order456', 'order789'] };

2. Security Rules

// firestore.rules rules_version = '2'; service cloud.firestore { match /databases/{database}/documents { match /users/{userId} { allow read: if request.auth != null; allow write: if request.auth.uid == userId; match /orders/{orderId} { allow read: if request.auth.uid == userId; allow write: if request.auth.uid == userId; } } } }

BigQuery

1. Dataset and Table Creation

-- Create dataset CREATE DATASET IF NOT EXISTS my_dataset OPTIONS( location="US", default_partition_expiration_days=30, description="My analytics dataset" ); -- Create partitioned table CREATE OR REPLACE TABLE my_dataset.events ( event_id STRING, user_id STRING, event_type STRING, event_timestamp TIMESTAMP, properties JSON ) PARTITION BY DATE(event_timestamp) CLUSTER BY user_id OPTIONS( require_partition_filter=true, partition_expiration_days=60 );

2. Query Optimization

-- Efficient query with partition filter SELECT user_id, COUNT(*) as event_count, ARRAY_AGG(DISTINCT event_type) as event_types FROM my_dataset.events WHERE DATE(event_timestamp) BETWEEN DATE_SUB(CURRENT_DATE(), INTERVAL 7 DAY) AND CURRENT_DATE() GROUP BY user_id HAVING event_count > 10 ORDER BY event_count DESC LIMIT 100;

Security Best Practices

1. IAM Configuration

# Set bucket IAM policy gsutil iam ch user:jane@example.com:objectViewer gs://my-bucket # Set Cloud SQL IAM policy gcloud sql instances patch my-instance \ --authorized-networks=192.168.1.0/24 # Set Spanner IAM policy gcloud spanner instances add-iam-policy-binding my-instance \ --member="user:jane@example.com" \ --role="roles/spanner.databaseUser"

2. Encryption Configuration

# Enable CMEK for Cloud Storage gsutil kms encryption \ -k projects/my-project/locations/global/keyRings/my-keyring/cryptoKeys/my-key \ gs://my-bucket # Enable CMEK for Cloud SQL gcloud sql instances patch my-instance \ --kms-key-name=projects/my-project/locations/us-central1/keyRings/my-keyring/cryptoKeys/my-key

Performance Optimization

1. Cloud Storage

# Enable Object Lifecycle Management gsutil lifecycle set lifecycle.json gs://my-bucket # Configure Cross-Region Settings gsutil rewrite -s NEARLINE gs://my-bucket/**

2. Database Optimization

-- Cloud SQL Index Optimization CREATE INDEX idx_user_email ON users(email); CREATE INDEX idx_order_date ON orders(created_at); -- Cloud Spanner Index CREATE INDEX AlbumsByTitle ON Albums(AlbumTitle) STORING (ReleaseDate); -- Firestore Index { "indexes": [{ "collectionGroup": "posts", "queryScope": "COLLECTION", "fields": [ { "fieldPath": "author", "order": "ASCENDING" }, { "fieldPath": "publishDate", "order": "DESCENDING" } ] }] }

Monitoring and Maintenance

1. Monitoring Setup

# Set up monitoring gcloud monitoring channels create \ --display-name="Storage Alerts" \ --type=email \ --email-address=alerts@example.com # Create alert policies gcloud alpha monitoring policies create \ --display-name="Storage Usage Alert" \ --condition-filter="metric.type=\"storage.googleapis.com/storage/total_bytes\" resource.type=\"gcs_bucket\""

2. Backup Configuration

# Cloud SQL backup gcloud sql backups create --instance=my-instance # Cloud Spanner backup gcloud spanner backups create backup-1 \ --instance=my-instance \ --database=my-database \ --expiration-time=$(date -d "+7 days" +%Y-%m-%dT%H:%M:%S%z)

Cost Optimization

  1. Storage Optimization

    • Use appropriate storage classes
    • Implement lifecycle policies
    • Clean up unused resources
    • Use compression where applicable
  2. Database Optimization

    • Right-size instances
    • Use appropriate machine types
    • Implement caching
    • Optimize queries

Best Practices

  1. Data Management

    • Implement proper backup strategies
    • Use versioning where needed
    • Follow naming conventions
    • Document data structures
  2. Security

    • Use appropriate IAM roles
    • Implement encryption
    • Regular security audits
    • Monitor access patterns
  3. Performance

    • Optimize access patterns
    • Use appropriate indexes
    • Monitor performance metrics
