SAP BTP Basics — Complete Beginner to Intermediate Guide

SAP BTP (Business Technology Platform) Overview

SAP BTP is SAP’s cloud platform that provides services for:

• Application Development
• Integration
• API Management
• Database & Data Management
• Analytics
• Artificial Intelligence
• Automation

Think of SAP BTP as the AWS/Azure platform for SAP workloads, where you can build, run, extend, and integrate applications.

Understanding the BTP Hierarchy

Global Account
    |
    +-- Subaccount
            |
            +-- Entitlements
            |
            +-- Environment
                    |
                    +-- Spaces
                            |
                            +-- Applications
                            +-- Service Instances

1. Global Account

What is it?

A Global Account is the top-level container in SAP BTP.

When a company purchases SAP BTP, SAP provides a Global Account.

Responsibilities

• Manage overall BTP landscape
• Allocate services to subaccounts
• Manage quotas
• User administration
• Monitoring usage

Example

Imagine Any XYZ Company purchases SAP BTP.

Global Account
= XYZ-Tech-BTP

Under this, different teams or projects can create subaccounts.

Real-Life Analogy

Think of a Global Account as an entire apartment building.

2. Subaccount

What is it?

A Subaccount is a logical partition inside the Global Account.

Subaccounts help separate:

• Development
• Testing
• Production
• Different Business Units

Example

Global Account
|
+-- Dev Subaccount
|
+-- Test Subaccount
|
+-- Prod Subaccount

Each subaccount has:

• Region
• Cloud Provider
• Services
• Applications
• Security configuration

Example Configuration

Subaccount Name: ERP-DEV
Region: India (Mumbai)
Cloud Provider: AWS

Real-Life Analogy

A Subaccount is an apartment within the building.

3. Spaces

What is a Space?

A Space exists inside the Cloud Foundry Environment.

It is used to organize applications and services.

Structure

Subaccount
    |
    +-- Cloud Foundry Org
            |
            +-- Space A
            +-- Space B

Example

ERP-DEV
|
+-- Backend-Space
|
+-- Frontend-Space
|
+-- Integration-Space

Why Spaces?

They help separate:

• Developers
• Teams
• Applications
• Resources

Real-Life Analogy

In an apartment:

Apartment = Subaccount

Living Room = Space 1
Kitchen = Space 2
Bedroom = Space 3

4. Entitlements

What are Entitlements?

Entitlements determine:

Which services can be used and how much of each service can be consumed.

Without entitlement, a subaccount cannot create services.

Example

Global Account buys:

API Management = 5 Units

Integration Suite = 10 Units

HANA Cloud = 2 Instances

The administrator distributes these to subaccounts.

Example Allocation

Dev Subaccount

API Management = 1
Integration Suite = 2

Prod Subaccount

API Management = 4
Integration Suite = 8

Real-Life Analogy

Think of entitlements as the budget allocated to each apartment.

5. Service Instances

What is a Service Instance?

A Service Instance is an actual running instance of a BTP service.

Once entitlement is available:

1. Choose service
2. Create service instance
3. Consume the service

Example

Entitled Service:

SAP HANA Cloud

Create Instance:

hana-db-dev

Now applications can use:

hana-db-dev

database.

Example

Service Available:

API Management

Create Instance:

api-management-dev

Now APIs can be published through it.

        |
        +-- Service Instances
                |
                +-- hana-dev
                |
                +-- api-mgmt-dev

How SAP API Management (APIM) Fits Into BTP

This is one of the most common interview questions.

What is APIM?

SAP API Management is part of:

SAP Integration Suite

It helps:

• Expose APIs
• Secure APIs
• Monitor APIs
• Throttle traffic
• Apply policies
• Manage API lifecycle

APIM Position in BTP

        |
        +-- Integration Suite
                |
                +-- API Management

Typical APIM Flow

Client App

     v
Backend System

Example:

Mobile App
      |
      v
SAP API Management
      |
      v
S/4HANA System

APIM acts as a gateway.

Why Use APIM?

Without APIM:

Mobile App
      |
      +----> S/4HANA

Problems:

• No Security
• No Rate Limiting
• No Monitoring
• No Analytics

With APIM:

Mobile App
        |
        v
SAP API Management
        |
        v
S/4HANA

Benefits:

✅ Authentication

✅ Authorization

✅ Rate Limiting

✅ API Analytics

✅ API Security

✅ API Monitoring

✅ Centralized Management

APIM Deployment in BTP

Step 1

Global Admin assigns entitlement.

Global Account
