Multi-Region Scheduling for Global Teams

Regional Independence Model for teams across US, EU, and Asia timezones. Demonstrates per-region schedules, tiered approach, and multi-cloud implementation.

Input

What you provide to the skill

Our team spans US, EU, and Asia timezones with dev environments in all 3 regions. We need resources available during each region’s work hours but want to cut costs. What scheduling strategy works?

Your Savings Analysis

THE CHALLENGE:
Traditional scheduling picks ONE timezone, disrupting other regions. Solution: Regional Independence with per-region schedules.

Regional Usage Pattern Analysis:

US Region (EST/PST):
- Active: 6am-9pm PST (15 hours)
- Idle: 9pm-6am PST (9 hours nightly)
- Idle hours/month: ~300 hours (41%)

EU Region (CET):
- Active: 7am-8pm CET (13 hours)
- Idle: 8pm-7am CET (11 hours nightly)
- Idle hours/month: ~350 hours (48%)

Asia Region (SGT):
- Active: 8am-8pm (12 hours)
- Idle: 8pm-8am (12 hours nightly)
- Idle hours/month: ~360 hours (49%)

WEIGHTED AVERAGE SAVINGS: 46%

Savings Projection ($1,000/month per region):

US Region:     $1,000 x 41% = $410/month
EU Region:     $1,000 x 48% = $480/month
Asia Region:   $1,000 x 49% = $490/month

Total Monthly Savings:  $1,380
Total Annual Savings:   $16,560

Recommended Strategy: Regional Independence Model

Tier 1: Personal Dev Environments

Schedule based on owner’s timezone
50-60% savings potential

Tier 2: Regional Staging

Nightly shutdown during local off-hours
45-48% savings

Tier 3: Global Integration

Keep ONE region 24/7 (cheapest - Asia)
30-35% savings on global resources

Implementation Scripts

AWS Multi-Region Schedules

US Region (9pm-6am PST off):

aws dynamodb put-item \
  --table-name InstanceScheduler-ConfigTable \
  --item '{
    "type": {"S": "schedule"},
    "name": {"S": "us-work-hours"},
    "periods": {"SS": ["us-weekday-hours"]},
    "timezone": {"S": "America/Los_Angeles"}
  }'

aws dynamodb put-item \
  --table-name InstanceScheduler-ConfigTable \
  --item '{
    "type": {"S": "period"},
    "name": {"S": "us-weekday-hours"},
    "begintime": {"S": "06:00"},
    "endtime": {"S": "21:00"},
    "weekdays": {"SS": ["mon", "tue", "wed", "thu", "fri"]}
  }'

EU Region (8pm-7am CET off):

aws dynamodb put-item \
  --table-name InstanceScheduler-ConfigTable \
  --item '{
    "type": {"S": "schedule"},
    "name": {"S": "eu-work-hours"},
    "periods": {"SS": ["eu-weekday-hours"]},
    "timezone": {"S": "Europe/Berlin"}
  }'

Tag Resources by Region:

# US resources
aws ec2 create-tags --region us-east-1 \
  --resources i-us-dev-001 \
  --tags Key=Schedule,Value=us-work-hours Key=Region,Value=us

# EU resources
aws ec2 create-tags --region eu-central-1 \
  --resources i-eu-dev-001 \
  --tags Key=Schedule,Value=eu-work-hours Key=Region,Value=eu

# Global (24/7 in cheapest region)
aws ec2 create-tags --region ap-southeast-1 \
  --resources i-global-integration \
  --tags Key=Schedule,Value=24x7 Key=EnvironmentTier,Value=global

GCP Implementation

# US Region stop at 9pm PST = 5am UTC
gcloud scheduler jobs create http stop-us-dev \
  --location=us-central1 \
  --schedule="0 5 * * 2-6" \
  --uri="https://REGION-PROJECT.cloudfunctions.net/scale?action=stop"

# EU Region stop at 8pm CET = 7pm UTC
gcloud scheduler jobs create http stop-eu-dev \
  --location=europe-west3 \
  --schedule="0 19 * * 1-5" \
  --uri="https://REGION-PROJECT.cloudfunctions.net/scale?action=stop"

4-Week Rollout

Week 1: Primary region pilot (US) - 2-3 resources
Week 2: Full US region rollout
Week 3: EU region rollout
Week 4: Asia region + global resource decision

Cross-Region Considerations

Asia team needs US resources? Keep global integration 24/7 in Asia
Cross-region dependencies? Document and keep those resources on 24x7 schedule
Overnight data sync? Keep sync infrastructure running

Per-Region Rollback

# Disable US region only
aws events disable-rule --region us-east-1 --name stop-us-dev
aws events disable-rule --region us-east-1 --name start-us-dev

# Start all US resources
aws ec2 start-instances --region us-east-1 \
  --instance-ids $(aws ec2 describe-instances --region us-east-1 \
    --filters "Name=tag:Region,Values=us" \
    --query 'Reservations[*].Instances[*].InstanceId' --output text)

Summary

Your Multi-Region Strategy:

Model: Regional Independence with tiered scheduling
Expected Savings: $16,560/year (46% reduction)
Implementation: 6-8 hours (1-2 per region)
Rollout: 4 weeks (staggered by region)
Safety: Per-region rollback, 24/7 global fallback

Next Action: Audit resources by region, implement Week 1 pilot in primary region.
