NO.19 As part of the mapping of a Business Architecture to the Solution Architecture, an Environment & Location Diagram must be developed in the Technology Architecture phase. In this context, numerous architecture decisions have to be made. Among other things, you must check which SAP BTP services and which SAP SaaS solutions are available as part of the Solution Architecture in which data center of the desired hyperscaler. How do you go about this validation?
According to the SAP Discovery Center 1 and the SAP Trust Center 2, the steps involved in this validation are:
Use the SAP Discovery Center to check which of the selected SAP BTP services are offered by which hyperscaler. The SAP Discovery Center is a platform that provides access to SAP BTP services, events, and related resources, and helps you to implement your use cases on SAP BTP with step-by-step guidance and support from topic experts and SAP Community. In the Service Catalog section of the SAP Discovery Center, you can browse and filter the available SAP BTP services by category, region, or hyperscaler. You can also compare the features and pricing of different services, and learn how to use them in your projects.
Use the SAP Trust Center to check in which data center the involved SAP SaaS solutions are available. The SAP Trust Center is a platform that provides information on cloud performance, security, privacy, and compliance. In the Certification and Compliance section of the SAP Trust Center, you can find certificates, reports, and attestations that show how SAP meets various industry standards and regulatory requirements. You can also filter the documents by solution, region, or hyperscaler, and download them for your reference.
The other options (A and C) are not correct for how to validate the availability of SAP BTP services and SAP SaaS solutions in the desired hyperscaler’s data center, because they either do not exist or do not provide the required information. For example:
Option A is not correct because there is no such platform as SAP Business Accelerator Hub (api.sap.com) that provides all the required information regarding SAP BTP service and SAP SaaS solution availability for each hyperscaler. The correct name of the platform is SAP API Business Hub (api.sap.com), which is a platform that provides access to SAP APIs, events, and related resources, but it does not provide any information on the availability of SAP BTP services or SAP SaaS solutions for each hyperscaler or data center.
Option C is not correct because the SAP Discovery Center does not provide any information on the availability of SAP SaaS solutions for each hyperscaler or data center. The SAP Discovery Center only provides information on the availability of SAP BTP services for each hyperscaler or region, but not for specific data centers. To check the availability of SAP SaaS solutions for each data center, you need to use the SAP Trust Center instead.
Topic 1, Case Study – Wanderlust
Introduction
Wanderlust GmbH, headquartered in Germany but with manufacturing facilities and sales globally, is a leading global manufacturer of conventional fuel driven cars. They are renowned for their best-in-class engineering, but not so much for aftermarket customer service. In recent years, Wanderlust has had limited success expanding into the market of electric vehicles. Following is Wanderlust’s geographical manufacturing and supply spread:

Wanderlust offers one compact electric Sedan (model ELAN) and one compact electric SUV (model ELUV), each with three variants – basic (LX), mid-range (VX) and high-end (ZX). Customers can also choose from a range of five metallic colors, two drive trains and two battery ranges.Overall, 50 different combinations are offered for all segments and variants put together.
Extracts from CEO Interviews – Business Environment
Constraints/Issues
o Stiff water consumption regulations and enormous penalties for violation – Lithium extraction is a heavy water intensive process and mine locations are in very arid areas like the Australian outback and Atacama Desert o Significant dependence on external suppliers of Lithium batteries due to limited number of manufacturing units, long lead times and high carbon footprint in all car manufacturing facilities except Brazil.
o Long delays in spare battery availability, leading to an avalanche of unresolved battery related customer complaints for vehicles under warranty o Limited charging infrastructure, long charging cycles (as compared to refilling fuel) and slow resolution of battery related complaints.
o Dwindling in store footfall due to pandemic (for feature-based vehicle selection prior to test drive) Wanderlust offers one compact electric Sedan (model ELAN) and one compact electric SUV (model ELUV), each with three variants – basic (LX), mid-range (VX) and high-end (ZX).

Wanderlust has a separate organization and setup for their Automobile and Aftermarket businesses o Wanderlust is reluctant to consider cloud for Core applications due to data privacy concerns, but are open for Collaboration applications o Automobile business started off in Europe and grew through acquisitions in Asia and Americas o Automobile business runs on three continental SAP ECC instances with inherited, disparate processes, which need to move to S/4HANA o Automobile business is also looking to harmonize their processes across the continents, adopt a seamless, transparent global supply chain for batteries and consolidate the continental instances into a global single instance, data regulations permitting o Automotive business uses a highly complex custom developed dealer management solution on ECC, which needs to be replaced o Automotive business uses SAP APO, which is nearing end of lifecycle and needs to be replaced by IBP (DP & SNP) & S/4HANA (PP-DS) o Automotive business uses several bespoke non-SAP applications, which are considered irreplaceable, except for the Marketing and Sourcing applications, whichare expensive to maintain, seldom used and henceneed to be replaced o Aftermarket business processes are largely uniform and handled through a single ECC instance which also should move to S/4HANA o Aftermarket business uses SAP SCM which is nearing end of lifecycle and needs to be replaced by S/4HANA AATP (gATP) and eSPP (SPP) Extracts from Interview with Enterprise Architect Enterprise Architecture Dimensions & Maturity o Wanderlust’s Key EA Dimensions, their overall purpose and current maturity level

Top three priorities given the current maturity level, are as follows
o Stakeholder Involvement is the topmost priority, to create a Stakeholder Map that’ll identify all key EA stakeholders within Wanderlust o Business-IT Alignment is also a top priority, to anchor every IT initiative to a Business Strategy Map, consisting of clearly defined strategic business objectives, tangible goals and measurable value drivers o Architecture Development is the next priority, beginning with development of business architectures, followed by application architectures and finally opportunities & solutions planning Enterprise Architecture Practice Structure (Current)

Enterprise Architecture Principles
o Wanderlust’s Enterprise Architecture Principles are a collection of crisp and precise one liners pertaining to business, application, information, integration, technology and security aspects of transformation o Some of the EA Principles in the repository are

These EA Principles serve as high level directional statements and long term guard rails to the above six aspects of transformation programs & projects o They should ideally correlate (many to many) with the Strategic Objectives, defined in the Business-IT alignment EA Dimension – this is yet to be done though
