Study Notes
System Integration
- System integration is the process of combining multiple subsystems into a single unified system.
Approaches
- Point-to-Point: Direct connections between systems. Simple setup but hard to manage as the system grows.
- Hub-and-Spoke: A central hub controls communication between systems. Easier to manage than point-to-point but the hub is a single point of failure making it vulnerable.
- Enterprise Service Bus (ESB): Middleware that facilitates communication. Scalable and easier to manage large, complex systems, but requires more initial setup.
Architectural Patterns
- Layered Architecture: Organizes software into layers (e.g., presentation, business logic, data). Changes in one layer don't impact others. Good for modular applications.
- Microservices Architecture: Breaks down a large application into small, independent services. Suitable for complex, distributed systems needing scalability.
- Services-Oriented Architecture (SOA): Systems expose services to each other through networks. Ideal for large organizations with many departments needing shared devices.
- Event-Driven Architecture: Systems communicate through events, useful for real-time systems such as trading platforms or social media notifications.
- Publish-Subscribe Architecture: Publishers send messages without knowing who subscribes. Useful for asynchronous communication where sender and receiver don't need real-time interaction.
Amazon and Microservices Architecture
- Decoupling of Services: Amazon's system is divided into small, independent services, each responsible for a specific function.
- Scalability: If one service experiences heavy traffic, only that service scales, not the entire system.
- Faster Development and Deployment: Different teams can work on different services independently, accelerating development.
- Failure Isolation: If one service fails, it doesn't affect other services.
Banking Systems and SOA
- Credit Checks: Services communicate with external agencies to assess customer creditworthiness.
- Account Management: Manages customer accounts and personal information.
- Payment Processing: Handles transactions like bill payments, online purchases.
Middleware in System Integration
- Middleware is specialized software to connect systems, applications, or services efficiently.
- It acts as an intermediary for systems built on different platforms, languages or databases.
- Crucial for seamless communication between systems.
- Enables interoperability between different systems.
- Important for scalability, security and error handling.
- Components: Message-Oriented Middleware (MOM), Database Middleware, Transaction Middleware, Application Servers.
- Examples: Apache Kafka, IBM MQ, TIBCO.
Data Management in System Integration
- Data management is the process, practices, and tools used to ensure smooth, accurate and consistent data flow.
- Critical for integrating multiple systems.
- Strategies: ETL (Extract, Transform, Load), Data Replication, Data Federation.
- Challenges: Data Silos, Data Inconsistency, Data Security and Privacy
Tools and Technologies for Data Management
- Middleware Solutions: Connect different systems for data exchange (e.g., Apache Camel, MuleSoft).
- Database Management Systems (DBMS): Manage data storage and retrieval (e.g., MySQL, Oracle, PostgreSQL).
- Data Governance Tools: Ensure data quality, security, and compliance (e.g., Talend, Informatica).
