Does Multi-Region Make Us Highly Available?
Leadership wants the system to be multi-region for high availability. What do you tell them?
Practical scenario
After a three-hour provider incident, leadership mandates multi-region within the quarter. The current architecture has a single-zone NAT gateway, a single-zone primary database and a deploy pipeline that pushes everywhere at once.
What it tests
Answer it out loud first. The guide below stays closed until you ask for it, on purpose.
- Whether the candidate separates geographic distribution from availability
- Whether they know what multi-region actually costs in consistency and complexity
- Whether they can propose the cheaper thing that meets the real requirement
Reading a strong answer is not the same as producing one. Commit to what you would say, then compare.
