Study Notes

SAP Technology Architecture

This unit outlines the development of a target technology architecture.
This architecture enables the target business architecture, application architecture and data architecture.
After completing this unit, learners will be able to: create an environments and location diagram, define an instance strategy, define a system landscape model and understand the SAP BTP account model.

SAP Enterprise Architecture Methodology

This methodology aligns with the TOGAF standard.
It is tailored to the SAP Reference Architecture.
It evolved from the IndRA framework.
It is used by SAP and its customers to systematically map IT solutions to business needs.
It is used internally by SAP to build enterprise architecture content.
Customers use this framework to define their desired future business scope and target architecture.

SAP EA Methodology – Metro Map

The MetroMap outlines the full set of recommended and optional architecture artifacts .
Input is drawn from the SAP Reference Architecture to define the target architecture in both business and IT domains.
It references existing architecture work products (principles, standards, guidelines, and baseline business and solution architectures).
The selection of artifacts depends on the architecture project and stakeholders.
The visualization is not intended to imply a waterfall approach.

Technology Architecture – Purpose & Artifacts

Documents the deployment of IT systems (hardware, software, and communications).
Develops Target Technology Architecture to enable the Target Business, Data, and Application Architecture
Key architectural work products: Environments and Locations Diagram, Network and Communications Diagram, container/virtualization environments and hardware specifications.

Technology Architecture – Steps

The objective of this phase is to develop the Target Technology Architecture while enabling the Architecture Vision, and target business, data, and application building blocks.
Identifying candidate Architecture Roadmap components based on gaps between the Baseline and Target Technology Architectures.
The development of the Baseline and Target Technology Architectures is to be delivered via technology components.

Technology Architecture – Information Sources

Environments and Locations Diagram is used to define solution data flow diagrams and solution process flow diagrams.
The recommended sources are:
- SAP Trust Center
- SAP Discovery Center
- Cloud Peering
- SAP product hardware requirements (SAP Online Help

Technology Architecture (Deployment/Landscape)

The Software Distribution Diagram outlines the distribution of Solution Building Blocks across the infrastructure.
The Environments & Location Diagram shows the physical installation of these building blocks in various locations (e.g., data centers).
The Network and Communications Diagram is used for documentation of network communication lines/VPNs.

Technology Architecture – Environments & Location Diagram

Diagram visualization, showing the geographical location of solution building blocks and runtime environment details.
Depicted are connections between Solution Building Blocks, and data center location.
Physical locations of the users and external systems are important considerations.
The data or content is exchanged over public lines/VPNs where necessary.
Security capabilities should be added as required.

Instance Strategy overview

Instance strategy describes typical scenarios including productive, development, and template considerations.
Different Instance Strategy approaches: Independent, Partial Template (Global/Local), Full Template-Multiple Production Instances, and Full Template-Single Production Instance.

SAP Instance - Terminology overview

SAP Landscape (Logical instance): A collection of environments used for common purpose release (e.g., production support or projects).
SAP Environment: A collection of instances for a specific purpose (e.g., development, testing, production).
SAP Instance: A single instance of given component with a specific role (e.g., DEV, PRD).
SAP Client: A logical and independent organization unit with separate master data.

SAP Client Concept - Terminology overview

Master Data: This data remains constant for a long period.
Transactional Data: Data for daily transactions.
Client-Specific Configuration: Customizations related to a specific client.
Client-Independent Configuration: Customizations that are valid for multiple clients.

Technology Architecture - System Landscape Model

The System Landscape Model defines the number of environments needed for the applications, with associated usage guidelines of each environment.
It includes the sequence of environments for transport flow, which is a critical aspect of managing changes throughout the system.

Technology Architecture - Three-System Landscape Model

This model presents QA (Quality Assurance) as a critical interim step before deployment in the PRD (Production).
Integrity of Transport sequence is maintained, and QA is periodically refreshed from PRD.
The primary limitation is supporting new projects/rollouts in parallel with production support.

Technology Architecture - Five-System Landscape Model

This model, compared to the three-system model, adds an extra development environment (DPS) to the existing DEV and QA.
The extra environment (DPS) allows more flexibility for projects that are separate from production support.
This model describes N and N+1 as different versions/configurations that are maintained as independent environments for development, and are linked for consistency when changes are replicated to N+1.
The benefit is that N+1 operations can be kept independent of previous versions.
The drawback is increased complexity in the systems and administration.

SAP S/4HANA Cloud 2-System Landscape

This landscape consists of a quality (or test) system and a production system.
The quality system handles development, configuration, and testing activities for custom developments and configurations before deployment in the production system, ensuring quality delivery.

SAP S/4HANA Cloud - Three System Landscape

The 3-System landscape consists of a development system, a test system, and a production system.
It's specifically designed for advanced development projects and enables greater developer capabilities.

SAP S/4HANA Cloud - Three System Landscape with Starter System

In the Explore phase of the SAP Activate roadmap, fit-to-standard workshops take place.
The starter system includes configuration and master data for the selected cloud solution.

SAP Business Technology Platform Account Model Overview

Each subaccount holds resources that can be used by apps.
Users and apps within the subaccount write related data.
Each subaccount belongs to a global account and a region.

SAP Account Model: Create Staged Development Environment

A subaccount for each specific development project is created for better governance and isolation.
Testing and production are combined into a single subaccount to further consolidate processes and compliance.
