Integration
Architecture

API integration patterns: REST, GraphQL, gRPC, and BFF.

AWS Glue is a fully managed extract, transform, and load (ETL) service that prepares data for analytics, machine learning, and application integration. It eliminates infrastructure management for data pipelines — no servers to provision, no clusters to maintain. Glue runs Apache Spark jobs, provides a Data Catalogue for metadata management, and offers a visual ETL builder for teams who prefer a no-code approach. For data integration requirements on AWS, Glue is the natural starting point before evaluating more specialised tools.

Event-driven integration patterns: pub/sub, event sourcing, and CDC.

Messaging integration patterns: queues, topics, and message broker architecture.

API-led connectivity is MuleSoft's reference architecture for structuring integration projects. It organises APIs into three tiers — System, Process, and Experience — each with a distinct responsibility and consumer. A System API wraps a data source or legacy system. A Process API orchestrates System APIs to execute a business capability. An Experience API shapes the data for a specific consumer — a mobile app, a web portal, or a partner. Together they create a reusable, composable integration layer that reduces point-to-point connections to zero.

MuleSoft Anypoint Platform is an integration platform that connects applications, data sources, and devices across on-premise and cloud environments through APIs. Its runtime engine — the Mule runtime — executes integration flows. Its management plane — Anypoint Platform — provides API design, deployment, monitoring, and a catalogue of reusable assets. For Ascendion engagements, MuleSoft is the preferred integration platform for heterogeneous enterprise environments where the client ecosystem spans Oracle, Salesforce, SAP, custom APIs, and legacy systems.

Oracle Integration Cloud (OIC) is Oracle's fully managed integration platform on Oracle Cloud Infrastructure. It provides pre-built adapters for Oracle and third-party applications, a visual flow builder for orchestrating integrations, a process automation engine for human workflow, and a monitoring console for operational visibility. For Ascendion engagements where the client runs Oracle EBS, Oracle ERP Cloud, Oracle HCM, or a significant Oracle application estate, OIC is the natural integration platform — its adapters for Oracle applications are deeper than any third-party tool.

Oracle Integration Cloud and MuleSoft Anypoint Platform are both enterprise integration platforms with strong market positions. For Ascendion engagements, the choice between them is one of the most consequential early architectural decisions on any integration project. The wrong choice creates years of friction — using a platform against its strengths adds cost, slows delivery, and builds technical debt. The right choice leverages what each platform does exceptionally well.

External partner integration patterns: B2B, API gateways, and data exchange.

Workflow and orchestration integration: BPM, saga, and stateful workflows.
