Introduction

Purpose

The purpose of this document is to outline the application architecture of SAP Cloud Integration as deployed by SyWay

Scope & Objectives

This document will describe the high-level architecture of the SAP Cloud Integration application.

Out of Scope:

Since SAP Cloud Integration is a SaaS application, network and infrastructure architecture will NOT be covered.
Product documentation and information that can be found online will not be documented here, but referenced using hyperlinks.
Implementation details such as Integration Design or API Management Design may have different architectures.

Application Architecture

Overview

Application Architecture Design
Insert the Architecture design below. Architecture can be designed in either Visio or word or another format.

Application Architecture Components

Component	Acronym	Description
Business Accelerator Hub		Business Accelerator is a centralized resource for developers and partners to build integrations and extensions for SAP solutions, access pre-built integration content, and accelerate digital transformation efforts. The key features of the hub is enabling the discovery of API, ability to use existing integration content provided by SAP and partners.
Cloud Integration	CI	Formally known as Hana Cloud Integration (HCI), CI is the core capability enabling the integration design and execution with SAP and non-SAP, cloud, and on-premise applications. CI enables Integration design via web based User Interface, providing orchestration of integration processes, connectivity to SAP, non-SAP, Cloud and On-Premise systems and Data Transformation.
API Management	APIM	APIM provides governance, security and monitoring of API, enabling exposure, management and monetization of APIs. APIM brings together all components necessary to expose and consume APIs providing capabilities for complete lifecycle of APIs, including, discovery, security, mediation, traffic management, analytics and documentation.
Event Mesh ( & Advanced Event Mesh )	EM ( & AEM )	EM provides the core infrastructure for enterprise-grade broker for event-driven architecture. It allow asynchronous communication between SAP and non-SAP.
Open Connectors		A Central Hub to access configurable connectors for over 170 non-SAP applications through harmonised APIs, enabling simplification and acceleration of integrations.
Integration Advisor & Trading Partner Management	IAE & TPM	IAE & TPM accelerate the development of business-oriented interfaces and mappings, generate runtime artefacts quickly, and significantly reduce efforts. Combined with AI-assisted tool for mapping and defining message interfaces, it provides industry-specific content based on standards like EDI, cXML, and assists in accelerated B2B/EDI mapping activity. A Central cockpit provides the ability centrally manage trading partner relationships.
Integration Assessment		Integration Assessment capability is a methodology and toolset for deciding when to use different integration techniques and patterns and provides guidance on integration strategy and helps standardize integration patterns across projects.
Migration Assessment		Migration Assessment assists the transition from legacy SAP Process Orchestration (SAP PO) environments to Integration Suite.
Graph		Graph provides the ability centralise and manage APIs to provide a unified Enterprise API exposing data from multiple SAP sources

Application Security

User Access

User Access to Integration Suite is via Web, and limited to technical user (developers, system administrators, support teams etc).

Authentication

User Authentication to Cloud Integration is via Single Sign-on (SSO) using Syensqo Entra ID federated to IdP. Username and Password logon are not permitted.
System Authentication options include
- OAuth 2.0 - access tokens issued via XSUAA
- Basic Authentication
Cloud Connector - for outbound traffic from Cloud Integration to On-Premise system - provides a TLS connection and authenticates via Principal Propagation

Authentication Flow

User accesses Cloud Integration tenant URL
The request gets redirected to SAP IdP configured in SAP BTP subaccount for Cloud Integration
User is re-directed to Corporate Identity Provider (IdP) logon page - Microsoft
User authenticates to Microsoft using Entra ID, if not already authenticated.
IdP validates and issues SAML 2.0 assertion back to BTP
SAP BTP maps the Role Collections assigned to the User
User accesses Cloud Integration

Authorisation

Standard Roles and Role Collections are assigned for User Access to Cloud Integration Components. Roles are assigned via SAP BTP Cockpit

System	Administrator	Developer	General Access
Cloud Integration	PI_Administrator	PI_Integration_Developer	PI_Read_Only, PI_Business_Expert
API Management	APIPortal.Administrator, APIManagement.SelfService.Administrator, AuthGroup.SelfService.Admin, AuthGroup.API.Admin	APIPortal.Configurator, APIPortal.Developer, APIPortal.Tester, APIPortal.Service.CatalogIntegration	APIPortal.Guest

Communication Security

For System-to-system communication, all data transfers are encrypted via a suitable mechanism - for example:

HTTP Adapter which uses TLS 1.2 as the standard ( HTTPS )
IDoc Adapter, which also uses TLS 1.2 as the standard ( HTTPS )
SFTP Adapter which uses SSH-2

Data Security

SAP data centers are certified to comply with global security standards, such as ISO/IEC 27001 and SOC 2. SAP implements stringent security measures including encryption, 24/7 monitoring, and regular audits.

Other Controls

System Availability SLA is 99.7% (documented in SAP Trust Center - Service Level Agreement for Cloud Services ).

Operation Architecture

Change and Configuration Management

This section will include the details related to change and configuration management of SAP and non-SAP systems.

Transport Management

here is some text

Release Management

SAP Release Management

Provides information on patch releases for hotfixes, bugfixes, and code enhancements. Patches for SAP Cloud Integration and Integration Advisor . Patch Release information covers the most recent changes made to the latest version of the software.

Monitoring

Monitoring available in SAP Cloud Integration (CI)

Message Monitoring - This core feature of SAP Cloud Platform Integration (SCPI), used to track, analyse, and troubleshoot the flow of integration messages between systems. It provides visibility into message processing, status, and potential errors, ensuring smooth operation of integration scenarios. Note - payloads are not captured by default, these may only be captured through explicit tracing with sufficient privilege in the system.
Integration Content - Deployed object status with associated error on failure.
Security Content - List displays of existing credentials (obscured passwords), certificates with expiry and custom user roles. Additional tooling is available for connectivity testing etc.
Datastore Monitoring - List display of local storage (global variables) for use by integration developers (correlations/aggregators).

Additional capability offered by FIGAF tooling - TBA

Monitoring available in API Management

Monitoring in SAP API Management provides transparency into how APIs are being consumed, their performance, and any potential errors. It allows administrators, developers, and business users to analyse API traffic, detect issues, and ensure APIs are meeting business and technical expectations.

API Analytics and Monitoring
Trace and Debug

Monitoring in Advanced Event Mesh

TBA

Application Monitoring

Provide the details of application monitoring configuration

System Monitoring

SAP System Monitoring - CALM and other common components

Sizing

SAP monitors system load and utilization, and proactively scales up capacity during release deployment.

High Availability

Disaster Recovery

SAP data centers are designed with redundancy and disaster recovery plans to help ensure business continuity. In the event of an outage, data and services are automatically rerouted to other operational centers.

Backup/Restore

SAP performs full backups with the following schedule to meet SAP's recovery point objective.

Tier	Frequency	Rentention
T1	Hourly	8 Days
T2	Daily	35 Days
T3	Every Sunday	120 Days
