Azure Integration Services

API Management

Logic Apps

Service Bus

Event Grid

Why Integration?

The Challenge

Disparate systems, apps & data sources
Cloud, on-premises, SaaS & partner systems
Different protocols, formats & APIs
Need for real-time & reliable communication

The Goal

Seamless connectivity across boundaries
Loosely coupled, composable architectures
Automate business processes end-to-end
Expose & manage APIs securely

Common Integration Patterns

🔄

API-Led Connectivity
Expose services via managed APIs

📋

Workflow Orchestration
Coordinate multi-step processes

💬

Messaging & Queuing
Decouple senders and receivers

⚡

Event-Driven
React to state changes in real time

Azure Integration Services

API Management

The front door for your APIs

API Management

What Is It?

Full lifecycle API management platform
API Gateway, Developer Portal & Management Plane
Unified entry point for internal & external consumers

Key Capabilities

Security — OAuth, JWT, certificates, IP filtering
Transformation — request/response rewriting
Rate limiting & throttling policies
Analytics & developer onboarding portal

Logic Apps

Visual workflow automation

Logic Apps

What Is It?

Cloud-based workflow automation platform
Visual designer — low-code / no-code
1400+ pre-built connectors
Connects SaaS, on-prem & custom systems

Common Scenarios

B2B integration (EDI, AS2, X12)
SaaS orchestration (O365, Dynamics, SAP)
Data transformation & routing
Automated approval workflows

Logic Apps

Logic Apps Hosting

Consumption (Multi-tenant)

Pay per action execution
Visual designer in Azure portal
Stateful workflows only
Easiest to get started

Standard (Single-tenant)

Runs on Azure App Service / ASE
Stateful and stateless workflows
VNet integration & private endpoints
Local development with VS Code

Logic Apps Connectors

1400+ connectors for Azure services, SaaS, enterprise systems, and more

☁️

Azure Services
Blob, SQL, Service Bus, Event Grid

🏢

Enterprise
SAP, Oracle, IBM MQ, DB2

📱

SaaS
Salesforce, O365, Dynamics, ServiceNow

🔌

On-Premises
Via data gateway — files, SQL, SAP

🌐

HTTP & Custom
REST, SOAP, webhooks, custom connectors

📊

B2B / EDI
AS2, X12, EDIFACT via integration accounts

Service Bus

Enterprise-grade messaging

Service Bus

Queues

Point-to-point messaging
Competing consumers pattern
FIFO with sessions
Dead-letter queue for failures

Topics & Subscriptions

Publish/subscribe pattern
Multiple independent subscribers
SQL & correlation filters
Fan-out to different consumers

Service Bus Key Features

🔒

Peek-Lock
At-least-once delivery guarantee

📦

Sessions
Ordered, grouped message delivery

💀

Dead-Lettering
Isolate unprocessable messages

🔁

Duplicate Detection
Idempotent message handling

⏱️

Scheduled Delivery
Future-dated message processing

🔄

Auto-Forwarding
Chain queues and topics together

Event Grid

Reactive, event-driven architectures

Event Grid

What Is It?

Fully managed event routing service
Push-based delivery to handlers
First-class Azure service integration
Pay per event — no idle cost

Key Concepts

Events — what happened
Sources — where it happened (Blob, custom, etc.)
Topics — endpoint for ingesting events
Subscriptions — route events to handlers

Event Grid Ecosystem

Event Sources

Azure Blob Storage
Resource Groups & Subscriptions
IoT Hub, Service Bus, Event Hubs
Custom topics (your applications)

Event Handlers

Azure Functions
Logic Apps
Webhooks (any HTTP endpoint)
Queues, Service Bus, Event Hubs

Better Together

          APIM exposes backend APIs and routes requests to Logic Apps, Functions, or direct
              services
Logic Apps orchestrates multi-step workflows, using Service Bus for reliable messaging
            
Service Bus decouples producers and consumers with guaranteed delivery
Event Grid reacts to Azure and custom events, triggering Functions and Logic Apps

        

Example: Order Processing

Security & Governance

🔐

Managed Identity
Passwordless Azure AD auth

🌐

VNet Integration
Private endpoints & network isolation

🔑

Key Vault
Secrets & certificate management

📜

Azure Policy
Enforce compliance at scale

📊

Azure Monitor
Logging, metrics & alerts

🛡️

RBAC
Fine-grained access control

Key Takeaways

          API Management — the front door: publish, secure & monitor APIs
Logic Apps — visual workflow orchestration with 1000+ connectors
Service Bus — reliable enterprise messaging (queues & topics)
Event Grid — reactive event routing at cloud scale
Better together — compose services to build end-to-end integrations
