.ebextensions/ Migration
Beanstalk .ebextensions/ YAML configs map to Bicep and App Settings:
.ebextensions/ Feature |
Azure Equivalent |
Implementation |
option_settings (env vars) |
App Settings |
Bicep siteConfig.appSettings |
packages (yum/apt) |
Startup script or Dockerfile |
Custom container or startup command |
files (config files) |
Deployment package or Blob Storage |
Include in app deployment |
commands / container_commands |
Startup command or deployment script |
az webapp config set --startup-file |
Resources (CloudFormation) |
Bicep modules |
Equivalent Azure resources |
services (sysvinit) |
WebJobs (continuous) or Azure Functions |
Background processing — App Service "Always On" only prevents idle unload; it is NOT a replacement for sysvinit-style background services |
Example: .ebextensions/ → Bicep
# .ebextensions/environment.config (AWS)
option_settings:
aws:elasticbeanstalk:application:environment:
NODE_ENV: production
DB_HOST: mydb.xxx.rds.amazonaws.com
// Bicep equivalent
resource webApp 'Microsoft.Web/sites@2023-12-01' = {
properties: {
siteConfig: {
appSettings: [
{ name: 'NODE_ENV', value: 'production' }
{ name: 'PGHOST', value: postgresServer.properties.fullyQualifiedDomainName }
]
}
}
}
RDS → Azure Database Migration
| RDS Feature |
Azure Equivalent |
| Multi-AZ deployment |
Zone-redundant HA |
| Read replicas |
Read replicas |
| Automated backups |
Automated backups (up to 35 days) |
| Parameter groups |
Server parameters |
| Subnet groups |
VNet integration + private endpoints |
| IAM authentication |
Microsoft Entra authentication |
| RDS Proxy |
Azure Database for PostgreSQL Flexible Server (built-in PgBouncer) |
💡 Tip: Use Azure Database Migration Service (DMS) for data migration from RDS.
Auto Scaling Migration
| Beanstalk Scaling |
App Service Autoscale |
MinSize / MaxSize |
Min/Max instance count |
Trigger metric (CPU, Network) |
Autoscale rules (CPU, Memory, HTTP queue) |
BreachDuration |
Time window + cool-down period |
ScalingAdjustment |
Scale-out/in increment |
| Time-based scaling |
Schedule-based autoscale rules |
resource autoscale 'Microsoft.Insights/autoscalesettings@2022-10-01' = {
properties: {
targetResourceUri: appServicePlan.id
profiles: [{
capacity: { minimum: '2', maximum: '10', default: '2' }
rules: [{
metricTrigger: {
metricName: 'CpuPercentage'
operator: 'GreaterThan'
threshold: 70
timeAggregation: 'Average'
timeWindow: 'PT5M'
}
scaleAction: {
direction: 'Increase'
type: 'ChangeCount'
value: '1'
cooldown: 'PT5M'
}
}]
}]
}
}
ALB → App Service Load Balancing
| ALB Feature |
Azure Equivalent |
| Path-based routing |
App Service path mappings or Front Door rules |
| Host-based routing |
Custom domains + Front Door |
| Health checks |
App Service Health Check feature |
| SSL termination |
Built-in TLS / Front Door |
| WAF |
Azure Front Door WAF or App Gateway WAF |
| Sticky sessions |
ARR Affinity (App Service) |
For global load balancing with WAF, use Azure Front Door instead of App Service built-in LB.
Environment Variables Migration
