Application Deployment Guide v1.0.0

# Create Blue and Green instance groups
slyd instance-group create --name my-app-blue --template app-template
slyd instance-group create --name my-app-green --template app-template

# Deploy application to Green environment (inactive)
slyd app deploy --app-id my-application --version v2.0.0 --group my-app-green

# Test application in Green environment
slyd tunnel create --name green-test --group my-app-green --port 8080

# Switch traffic from Blue to Green
slyd load-balancer update --name my-app-lb --active-group my-app-green

# If issues occur, quick rollback to Blue
slyd load-balancer update --name my-app-lb --active-group my-app-blue

# Deploy canary version alongside current version
slyd instance-group create --name my-app-canary --size 2 --template app-template
slyd app deploy --app-id my-application --version v2.0.0 --group my-app-canary

# Configure load balancer for canary traffic splitting
slyd load-balancer update --name my-app-lb \
  --primary-group my-app-production --primary-weight 90 \
  --canary-group my-app-canary --canary-weight 10

# Monitor performance metrics
slyd metrics watch --groups my-app-production,my-app-canary \
  --metrics response_time,error_rate,throughput

# Gradually increase traffic to canary
slyd load-balancer update --name my-app-lb \
  --primary-group my-app-production --primary-weight 75 \
  --canary-group my-app-canary --canary-weight 25

# Complete the migration
slyd load-balancer update --name my-app-lb \
  --primary-group my-app-canary --primary-weight 100

# Clean up old deployment
slyd instance-group update --name my-app-production \
  --template app-template-v2
