Microservices communication can become confusing due to the ambiguous use of terms like "upstream" and "downstream," leading to misunderstandings in technical discussions. The article highlights how these terms, often used to describe data flow between services, lack precision because they can be interpreted differently depending on the context. This ambiguity arises because data flows bi-directionally in HTTP interactions, similar to ocean tides rather than a single stream. To address this, the author suggests using terms based on the relative roles of services, such as "supporting service" and "client service," which provide clearer communication by focusing on service relationships rather than data direction. This approach has improved the author's ability to hold precise and efficient conversations about microservices interactions. Additionally, the text briefly introduces the Split Feature Data Platform™ as a tool for feature management, enabling safe and controlled feature deployments, A/B testing, and efficient team collaboration to enhance software development processes.
