This article provides best practices for implementing event-driven architectures (EDA) in organizations, focusing on component responsibilities and team ownership models.

• Event-driven architectures consist of producers, message brokers, and consumers with distinct responsibilities
• Producers own event schemas and manage breaking/non-breaking changes
• Message brokers ensure event durability and regulate access permissions
• Consumers handle event effects and manage failure/duplicate message scenarios
• Decentralized ownership promotes team independence but requires strong DevOps culture
• Centralized ownership standardizes non-functional requirements but risks becoming a bottleneck
• Implement cloud center of excellence (CCoE) for standardized non-functional implementation
• Decentralize message broker ownership to producing teams for maximum agility
• Centralize logging standards and observability strategies across engineering teams

The recommended approach balances team independence with standardization through decentralized ownership, CCoE guidelines, and centralized observability practices.
