Building Nodejs Apps with SAP BTP on Microsoft Azure What Developers Discovered

Introduction

Enterprises building intelligent, modern, cloud-native applications have found that the environment provided by SAP Business Technology Platform (SAP BTP) with Microsoft Azure is an industry leader for deploying scalable business solutions.
For SAP developers, particularly Node. js, this landscape provides a Web based headline Ecosystem which is fast, secure and integration eloquent.

But what will actually get developed in this environment?
In this post, we’ll investigate what engineers learned while creating Node. js applications on SAP BTP Health module: Content presented in this article is about using Node.

Key Highlights Developers Noticed

In SAP on Azure, Services Are Interoperable

Developers were surprised at how easy it is to wire SAP BTP services (such as XSUAA, CAP, Destination service) with common Azure services like Key Vault, Storage, API Management and Azure AD.

Scalable Node. js Runtime for Enterprise Apps

Node. js on SAP BTP (Cloud Foundry or Kyma) scales very well and things like automatic-scaling, monitoring and global networks are also available when using Azure.

Enterprise-Grade Security by Default

By utilizing Azure AD, SAP Identity services, OAuth 2.0 + managed secrets a secure & compliant platform for enterprise Node is established. js deployments.

Hybrid Integration Patterns Work Seamlessly

For companies that operate SAP S/4HANA, SAP ECC or other SAP cloud applications, BTP and Azure can offer more adaptable system integration options at scale.

Knowledge of the SAP BTP and Azure Landscape

SAP BTP

SAP BTP provides:

• Cloud Application Programming Model from SAP (CAP)
  
• Node.js runtime environments
  
• Extension Suite for custom-developed apps
  
• Integration Suite
  
• Security services
  
• Database services, such as SAP HANA Cloud
  

Microsoft Azure

Azure provides:

• Compute services (VMs, Kubernetes, Functions)
  
• Networking and security
  
• Global data centers
  
• Monitoring and observability
  
• Azure AD identity services
  
• Azure API Management
  
• Azure Storage and databases
  

Why do enterprises pair them?

This is because SAP BTP is designed for “SAP-centric development” but with Azure, you have access to global-scale compute, network, analytics and identity.

Together, they offer:

• A unified development environment
  
• Hybrid integration capabilities
  
• Scalable Node.js runtime
  
• Enterprise security
  
• Consistent CI/CD workflows
  

Why Node. js Became the Preferred Choice

Developers highlighted Node. js as the runtime of choice for SAP BTP applications running on Azure.

• Event-Driven Architecture
  Great for APIs, workflows, and integrations.
  
• High I/O Performance
  Great for services that talk to SAP systems and the Azure APIs.
  
• Smooth Integration with CAP
  CAP for Node. js while keeping the sanity of a structure.
  
• Strong Open-Source Community
  Assists devs with rapid problem resolution and speedier builds.
  

What We Learned About Building Node. js Apps on SAP BTP and Azure

Discovery 1: Integration Delivers Impact but Needs Initial Investment

Every interviewee who had integrated dashboards with logs and traces explained that it was beneficial, but it required expertise built up front.
Developers say SAP BTP is seamless once you set it up with Azure.

Complexity appears during:

• Trust Relationship between Azure AD and XSUAA
  
• Setting up SAP Destination service for Azure APIs
  
• Secure secret management with Key Vault
  
• Network routing and setting up the private endpoint
  

Once enabled, the integration is smooth and secure.

Finding 2: Secure Enterprise Ready, Azure AD and XSUAA to the Rescue!

Developers realized its trust model is very secure.

Benefits include:

• Single sign-on
  
• OAuth and JWT-based authorization
  
• Clear role-based access
  
• Zero-trust identity
  

Many organizations have begun to standardize on Azure AD for all of their SAP BTP extensions.

Discovery 3: CAP with Node. js Reduces Development Time Significantly

“Developers said that creating something with CAP takes 40–60% less time than otherwise.”

They benefited from:

• Built-in CRUD operations
  
• Automatic OData handling
  
• Integrated authentication
  
• Easy SAP HANA Cloud integration
  
• Azure PostgreSQL and MS SQL support
  

Discovery 4: Azure Monitoring Significantly Increases Application Visibility

Developers appreciated:

• Distributed tracing
  
• Runtime performance analytics
  
• API failure tracking
  
• Centralized logs
  
• Connection-level insights
  

This is a much needed benefit in multi-cloud SAP scenario.

Finding 5: Cost Optimization Demands Preparation and Planning

Developers cautioned that costs may add up quickly if they aren’t monitored closely.

Best practices:

• Use free-tier BTP for development
  
• Clean unused instances regularly
  
• Servicing to actual size is what’s needed
  
• Track spending with Azure Cost Management
  
• Use autoscaling only where justified
  

Discovery 6: Kyma Runtime & AKS FTW

Discover this and other stories of growth from #KubeCon on Dec. […]

Developers discovered that for microservices and event driven architectures:

• SAP BTP Kyma
  
• Azure Kubernetes Service (AKS)
  

work extremely well together.

Benefits:

• Kubernetes-native development
  
• High scalability
  
• Strong integration with Azure services
  
• Managed secrets and events
  

Discovery 7: Performance with Private Link and Connectivity Is Enhanced

Increases in performance were reported by developers running on private networking versus public endpoints.

Private links reduce:

• Latency
  
• Security risks
  
• API failures
  

Real-World Use Cases Developers Built

Use Case 1: Extensions of SAP S/4HANA

Extensions such as:

• Workflow approvals
  
• Sales order automation
  
• Custom Fiori apps
  
• Supplier portals
  

All built with Node. 3 video.js CAP and Azure AD & Storage Integration The BRN contains the last playback information.

Scenario 2: Smart Dashboards Using Azure AI

For this scenario, smart dashboards would be reliant on the power of the Azure platform.

Developers combined SAP data with:

• Azure AI
  
• Azure Synapse
  
• Azure Cognitive Services
  

To build:

• Demand forecasting apps
  
• Predictive maintenance dashboards
  
• Ticket classification systems
  

Example 3: IoT + SAP Business Processes

For example, by leveraging Azure IoT Hub with SAP BTP Integration Suite, the following were developed:

• Predictive maintenance flows
  
• Automated spare parts ordering
  
• Real-time equipment dashboards
  

Best Practices Developers Recommend

• Use CAP for efficient Node. js development
  
• Use Azure AD to manage enterprise identity
  
• Consolidate secrets in BTP Credential Store or Azure Key Vault
  
• Consider Azure API Management for external APIs routing
  
• Use CI/CD with GitHub Actions or Azure DevOps
  
• Use autoscaling wisely
