Dan Lepow provides a detailed migration guide for teams moving from Amazon API Gateway to Azure API Management, offering technical mapping and step-by-step planning for architects and engineers.

Migrating from Amazon API Gateway to Azure API Management

Overview

This migration guide provides technical guidance for teams transitioning from Amazon API Gateway to Azure API Management. It covers feature mapping, architectural differences, migration planning, validation steps, and real-world examples to ensure a smooth and effective migration.

Key Topics Covered

Detailed Feature Mapping

Mapping infrastructure (VPC endpoints ↔ Azure virtual networks)
WAF integration, custom domains, observability (CloudWatch ↔ Azure Monitor)
API workloads: Lambda proxy integrations, REST APIs, HTTP APIs
Configuration: stage variables, caching, throttling, CORS, authentication methods
Guidance for non-equivalent features with suggested workarounds (e.g., Lambda authorizers)

Assessment and Preparation

Systematic assessment of AWS deployment against Azure features
Identification of retained/replacement services
Documentation of API configurations and data flows
Exporting OpenAPI specs and authentication flows
Establishing performance baselines for migration

Migration and Validation

Phased migration: service tier selection, network topology planning
Configuring parallel environments for risk mitigation
Validation: configuration checks, DNS cutover process
Post-migration optimization and continuous improvement tips

Architecture-Focused Example

Healthcare scenario: original AWS architecture (Cognito, WAF, Lambdas, EC2, EKS)
Azure equivalent: Microsoft Entra ID, Azure Application Gateway + WAF, Azure Functions, AKS, private endpoints
Maintaining network isolation, monitoring, and security
