Serverless Scale-to-Zero Database

Problem Being Solved

Root Cause: Traditional databases require always-running processes to handle connections:

• Connection State: TCP connections timeout if server goes away
• Storage Coupling: Compute and storage tightly coupled, cannot scale independently

Key Capabilities

2. True Scale-to-Zero

-- Database automatically suspends after inactivity
ALTER DATABASE my_dev_db SET suspend_timeout = '5 minutes';

-- Cost during idle:

psql postgres://my-dev-db.db.example.com/db

4. Predictive Scaling

-- Enable predictive autoscaling
SELECT heliosdb_configure_autoscaling(
    database => 'production',
    min_cu => 2,
    max_cu => 32,
    scaling_mode => 'predictive',  -- Uses ARIMA/LSTM
    scale_up_threshold => 70,      -- CPU %
    scale_down_threshold => 30,
    cooldown_seconds => 60
);

Concrete Examples

Example 1: Development Team Database Optimization

Company Profile: SaaS startup with 40 developers, each with their own database

Example 2: Multi-Environment Cost Optimization

Company Profile: E-commerce platform with production, staging, and 10 feature environments

Example 3: SaaS Multi-Tenant Optimization

Company Profile: B2B SaaS with 500 tenant databases, varied usage

Example 4: Event-Driven Application

Company Profile: Concert ticketing platform with extreme traffic spikes

HeliosDB Solution:

-- Configure for burst workload
SELECT heliosdb_configure_autoscaling(
    database => 'ticketing',
    min_cu => 0,           -- Scale to zero when idle
    max_cu => 128,         -- Massive burst capacity
    scaling_mode => 'aggressive',
    scale_up_sensitivity => 'high',
    burst_multiplier => 10
);

-- Schedule-based pre-warming
SELECT heliosdb_schedule_warmup(
    database => 'ticketing',
    schedule => 'cron(55 9 * * ? *)',  -- 9:55 AM daily
    target_cu => 64,
    warmup_queries => ARRAY[
        'SELECT * FROM events WHERE on_sale_date = CURRENT_DATE',
        'SELECT * FROM seating_charts WHERE event_id IN (...)'
    ]
);

Example 5: Global Startup Expansion

Company Profile: Fintech startup expanding from US to Europe and Asia

Challenge: Need database presence in 3 regions but traffic varies

Implementation Roadmap

Quick Start

# Install CLI
$ brew install heliosdb-cli

# Create serverless database
$ heliosdb create myapp-dev --serverless
Database 'myapp-dev' created
Endpoint: postgres://myapp-dev.db.example.com:5432/db

# Connect and use
$ psql postgres://myapp-dev.db.example.com/db

Migration from RDS

# 1. Create HeliosDB database
$ heliosdb create myapp-prod --serverless --region us-east-1

# 2. Configure autoscaling
$ heliosdb configure myapp-prod \
    --min-cu 0 \
    --max-cu 16 \
    --suspend-timeout 300

# 3. Import data
$ heliosdb import myapp-prod \
    --source postgres://rds-instance.aws.com/db \
    --method cdc  # Zero-downtime migration

# 4. Switch traffic
$ heliosdb dns myapp-prod --from rds-instance.aws.com
Traffic switched. RDS can be terminated.

Conclusion

HeliosDB's serverless scale-to-zero capability fundamentally changes database economics.

• Scale Fearlessly: Handle any traffic pattern without pre-provisioning
• Simplify Operations: No capacity planning or instance sizing
