AI Cloud Architecture

Separate interactive and background workloads where their requirements differ. A user waiting for an answer needs bounded response time, while batch processing can use queues and longer-running jobs. Make queue status and retry behavior observable. Define data boundaries and access roles. Documents, embeddings, model artifacts, and logs may have different retention and permission requirements. Keep credentials in appropriate secret management and avoid assuming that network location alone establishes authorization. Plan for capacity changes and dependency failures. Autoscaling can take time, model loading can be expensive, and a provider can impose rate limits. Use admission controls, backpressure, bounded retries, and clear unavailable states to prevent one overloaded dependency from overwhelming the whole service. Version the deployment and test recovery. Check compatible model and preprocessing versions, data migrations, and rollback procedures. Measure cost per useful completed task, including storage, transfer, failed attempts, and idle resources. A low price for one API call may hide a more expensive overall workflow.
