Coordination Patterns
Explore coordination patterns in distributed systems focusing on orchestration and choreography methods. Understand how systems cooperate to perform business functions, the difference between functions with and without side effects, and how atomicity is ensured through protocols like two-phase commit and saga transactions. This lesson aids in grasping the design and trade-offs of coordinating distributed components effectively.

For example, displaying a product page might require combining functionality from different systems, such as an advertising system, a recommendation system, a pricing system, etc.
