Enables Architectural Patterns

Layered Architecture

Organize code into layers (presentation, business, persistence, database) with clear responsibilities and boundaries (often deployed across N‑tiers).

N‑Tier (Client‑Server) Architecture

Multi-tier runtime architecture (e.g., presentation, application, data) where clients request services from servers across tiers.

Service-Oriented Architecture (SOA)

Reusable, contract-driven services integrated via mediation (often ESBs) with centralized governance; a precursor to microservices.

What it is

Integration services enable interoperability across SaaS, legacy, and bespoke systems using a mix of synchronous and asynchronous patterns.

Responsibilities

  • Connectivity (REST, SOAP, JDBC, SFTP, EDI)
  • Mediation (mapping, transformation, enrichment)
  • Orchestration and routing
  • Operational visibility and error handling

Core capabilities

  • Connector catalog and lifecycle
  • Contract-first transformations and testing
  • Secrets management and policy enforcement
  • Self-service integration pipelines

Architecture patterns

  • Canonical data models
  • Event-driven integration
  • File-based and batch with idempotency
  • Edge adapters and strangler patterns

Tech examples

  • WSO2 Integrator: Ballerina Integrator
  • WSO2 IPaaS solution: Devant
  • MuleSoft
  • Boomi
  • Apache Camel
  • Spring Integration
  • Azure Integration Services

KPIs/SLIs

  • Success rate and MTTR for integrations
  • Throughput and latency per flow
  • Change lead time and failure rate
  • Partner SLA adherence
