Integration-Patterns

Micro‑Frontend Architecture: Agile UI Composition Micro-frontends break a large UI into smaller, independent pieces. Each piece, or micro-frontend, is built, tested, and deployed by a team that owns a feature end to end. A lightweight shell stitches these pieces together, so users see a cohesive app even though the parts are separate. This approach helps teams move faster and lowers risk when the business needs change. Benefits include faster delivery, clearer ownership, and resilience to change in one area. Drawbacks include extra integration work, shared UX concerns, and potential performance costs if interfaces leak. ...

ERP and CRM Integration Patterns ERP and CRM systems touch core business data, but they serve different needs. Integration helps sales teams see order status, service teams view inventory, and finance keep books in sync. A clear pattern reduces data silos, prevents duplicates, and speeds decision making. Start with a small, well-defined flow and grow from there. Common integration patterns Point-to-point direct integration A simple link between two systems. It is quick to start, but becomes hard to maintain as more systems join and data formats diverge. ...

Middleware as the backbone of enterprise integration Middleware acts as the backbone of enterprise integration. It sits between applications, databases, and devices to move data, translate formats, and manage traffic. With it, teams connect systems without rebuilding every integration from scratch. It also helps enforce security policies and data governance across the landscape. Most enterprises rely on a mix of patterns: message queues, API mediation, event streams, and routine workflows. These patterns let services work at their own pace, while the business stays coordinated. When done well, middleware also improves compliance, observability, and control over data flow across departments and borders. ...

APIs and Middleware: Building Bridges Between Systems APIs and middleware act as bridges between different software systems. APIs expose services and data in a stable, machine-friendly way. Middleware sits between apps and the network, handling tasks like routing, security, and data shaping. Together, they let teams build flexible architectures without forcing every system to change at once. The goal is predictable communication, not chaos. Think of contracts first. An API contract defines what you promise to others and what you require in return. Keep it simple, versioned, and backward compatible when possible. Use clear naming and documented inputs and outputs. When middleware sits in between, it translates, validates, and guards these contracts, so one side can evolve without breaking the other. ...

Middleware Patterns for Enterprise Architectures Middleware acts as the glue between apps and services. In large organizations, a deliberate mix of patterns helps teams decouple systems, scale efficiently, and stay compliant with security and governance rules. The goal is to choose patterns that fit business needs, not just the newest tech trend. Common patterns API gateway: a single entry point that handles routing, authentication, and protocol translation for external clients. Service mesh: manages internal service-to-service communication with traffic shaping, retries, and observability. Message broker or event bus: enables asynchronous communication so components can work independently. CQRS and event sourcing: separate read and write models to optimize queries and enable audit trails. Saga patterns: coordinate long-running transactions with either choreography or orchestration and compensating actions. Backend for Frontends (BFF): tailor APIs for each client, improving performance and experience. Adapter and Facade: connect legacy systems and simplify complex interfaces for newer services. Example: a purchase flow uses an API gateway to expose services, writes a Order event to a broker, and uses a Saga to coordinate inventory and payment with compensations if something fails. ...
