Plan a Monolith-to-Cloud Migration is a medium cloud architecture interview question covering cloud migration, cloud architecture, lift and shift, managed services, hybrid cloud — the kind asked at FAANG (Facebook/Meta, Apple, Amazon, Netflix, Google) and AI-first companies like Anthropic, OpenAI, and Nvidia.
An established application runs in a data centre whose lease ends in about a year and will not be renewed. It uses one large relational database of about four terabytes, a shared file store, a message broker, and several internal systems - some of which are not moving. It writes to local disk and has a licensed component tied to a hardware identifier. Plan the move. A planned hour of downtime on a weekend night is acceptable.
