Cloud Storage

1. Storage Classes

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)
