2627 questions of the kind that actually get asked — in interviews, in architecture review boards, and by the person who has to run the thing at 3 AM. Every answer states the trade-off rather than the slogan, and says when the obvious choice is the wrong one.

A deployment platform's control plane goes down. What should happen to customer applications already serving traffic, and what does that requirement force into the architecture?

A real-time conferencing platform must serve unpredictable demand that once grew thirtyfold in ten weeks, where media relaying is bandwidth-intensive and latency-critical. Should it run on public cloud, its own data centres, or both - and what decides?

In the 2017 AWS S3 outage, the status page could not report the outage because it depended on S3. What does that tell you about designing status and control systems?

The December 2021 us-east-1 event began with internal network congestion that impaired the region's control plane, and customers found they could not even read the service health dashboard. What are the three durable architectural lessons, independent of the specific bug?

The business asks for "multi-region" after a regional outage. Before agreeing, what do you need to establish, and what are you actually signing up for?

You plan a regional failover. Name every dependency that must already exist in the second region for the plan to be executable, not just for traffic to be served.

Several 2023–2024 regional cloud outages were triggered by automated control-plane or configuration changes rather than by hardware failure or code deploys. How should change management, progressive rollout and control/data-plane independence be designed?

You inherit a cloud estate with one account, no tags, shared root credentials and no policy enforcement. What are your first three changes and in what order?

A lift-and-shift migration produced a cloud bill 2.5 times the data-centre cost it replaced. What do you examine first and what is the fastest meaningful reduction?

A travel platform must migrate a large legacy booking system to cloud services without a big-bang cutover. Design the migration using a strangler approach, and identify what makes data the hard part.

You are asked to lead a migration of 300 applications to cloud. What happens in the first ninety days?

A GPU platform has a few very large jobs competing with thousands of small ones. How should scheduling fairness, fragmentation, bin packing, preemption, queueing and starvation shape the architecture?
