1. Central Security Governance and Monitoring: We implemented an iPaaS (MuleSoft) solution with centralized security governance to ensure compliance and control over all data flows. 

2. Security Compliance: ITKnocks used advanced security patterns to ensure that data exchange was secure and compliant, including: 

• Zero Trust Architecture: Each interaction was verified at every stage. 
• OAuth 2.0 and JWT Authentication/Authorization: Ensured secure handling of authentication and authorization. 
• Mutual TLS: Secured communication between integrated systems. 
• Role-Based Access Control (RBAC): Managed access control with fine-grained permissions. 
• Data Encryption: Applied to secure sensitive information. 

3. Real-Time Processing, Data Synchronization, and Integration: Various design patterns were employed to meet different use cases: 

• Publish-Subscribe (Pub-Sub): For asynchronous communication between systems. 
• Event-Driven Architecture: To process real-time data changes across platforms. 
• Synchronous & Asynchronous Processing: Depending on business needs, both processing types were implemented. 
• Polling: For periodic updates. 
• Message Broker Pattern: To ensure loose coupling between services. 

4. Unified View and Real-Time Data Synchronization: One of the primary goals was to deliver a unified view of customer data in Dynamics 365 CRM, ensuring seamless integration and real-time data synchronization across legacy and cloud systems. We implemented Microsoft Dynamics 365 CRM for Sales, Marketing, and Customer Service, alongside custom APIs, automated workflows using Power Automate, and data modelling in Dataverse.
