Worked Example: A Written Strategy

Here is an exercise. Try it before reading further.

Write a one-page technical strategy for messaging at the marketplace. You have 90 minutes.

Of the marketplace's 180 services, 120 use messaging: 52 on RabbitMQ, 38 on Kafka, and 30 on Amazon SQS. Each technology has its own on-call rotation and its own client libraries. Last half-year, 3 incidents came from teams that applied one technology's assumptions to another. The VP of Engineering wants a strategy that the 45 teams can follow without asking for a meeting each time.
