AWS Fargate to Azure Container Apps Migration

Guidance for migrating AWS Fargate (ECS) containerized workloads to Azure Container Apps.

Overview

AWS Service	Azure Equivalent	Notes
ECS Fargate	Azure Container Apps	Serverless container platform
ECR	Azure Container Registry	Private container registry
Application Load Balancer	Container Apps Ingress	Built-in HTTPS
AWS Secrets Manager	Azure Key Vault	Managed identity integration
CloudWatch Logs	Azure Monitor/Log Analytics	Requires Log Analytics workspace on environment
CloudWatch Metrics	Azure Monitor Metrics	Available without Log Analytics workspace
IAM Roles (tasks)	Managed Identity	Microsoft Entra ID integration
VPC	Virtual Network	VNet integration
Security Groups	NSG + Container Apps rules	Network security
Auto Scaling	Container Apps scaling rules	HTTP, CPU, memory, custom
Parameter Store	App Configuration or Key Vault	Configuration management

Critical Differences

Feature	AWS Fargate	Container Apps	Impact
Max vCPU	16 vCPU	4 vCPU (Consumption Plan)	Split CPU-intensive tasks
Max Memory	120 GiB	8 GiB (Consumption Plan)	Redesign memory-heavy workloads
GPU	Available (ECS)	Supported (preview)	Validate GPU SKU availability
Sidecar Containers	Supported (ECS)	Supported (init + sidecar)	Compatible pattern
Task Placement	Placement strategies/constraints	No node-level control	Remove placement logic
Persistent Storage	EFS mounts	Azure Files only	Migrate to Azure Files or Blob
Max Replicas	Service-dependent	300 per revision	Validate scale requirements
Networking	VPC + Security Groups	VNet + NSG	Subnet-level isolation
Startup Timeout	No platform limit	240s default	Optimize startup time

Migration Workflow

Service Dependency Mappings

AWS Service	Azure Equivalent	Notes
S3	Azure Blob Storage	SDK change (boto3 → azure-storage-blob)
DynamoDB	Azure Cosmos DB	API compatibility or code changes
SQS	Azure Service Bus / Queue Storage	SDK change
SNS	Azure Event Grid / Service Bus Topics	SDK change
RDS	Azure Database for PostgreSQL/MySQL/SQL	Connection string + managed identity
ElastiCache (Redis)	Azure Cache for Redis	Connection string update
Parameter Store	Azure App Configuration / Key Vault	SDK change
EventBridge	Azure Event Grid	SDK change required
Step Functions	Azure Logic Apps / Durable Functions	Workflow redesign
Kinesis	Azure Event Hubs	SDK change required
X-Ray	Application Insights	Requires SDK + connection string setup
CloudWatch Logs	Azure Monitor Logs	Requires Log Analytics workspace on environment
