The depth shows up in the details: SLA tuning, IAM and KMS boundaries, regional data residency, model selection by workload class, and the procurement paths that get production systems through enterprise review without a six-month gate. Each of these platforms has a sweet spot, a cost cliff, and a set of failure modes the docs don’t advertise — that’s the knowledge we bring to the table on day one.
The architecture decision is the first engineering decision — and the one most teams under-spec. We choose the stack for the workload in front of you: which inference latency you can defend at scale, which data has to stay on-prem, which orchestration belongs in Kubernetes versus serverless, and which compounding compute costs need to be designed out before they ever reach the operating budget. Picking the platform correctly is what makes the project possible.
