Operational excellence
Isnta decision: Infrastructure as code, repeatable no-AI deployments, observable jobs, explicit queue operations, and recovery paths reduce routine operational work.
Customer responsibility: Operators still own alarms, response procedures, tested rollback, and controlled access to the deployment identity.
Security
Isnta decision: Readers receive static files through CloudFront while the private bucket, administrator, structured content, and model boundaries remain isolated.
Customer responsibility: Owners must manage administrator identities, AWS permissions, template code, secrets, dependencies, and vulnerability response.
Reliability
Isnta decision: Published files remain readable when administration, generation, or queue processing fails. Versioned source records support rebuild and recovery.
Customer responsibility: Owners must test restoration, monitor failures, and validate regional and service assumptions for their workload.
Performance efficiency
Isnta decision: Pages are generated before requests, cached at the edge, and delivered with limited reader-side JavaScript.
Customer responsibility: Owners must measure real-user performance, optimise publication assets, and choose an appropriate CloudFront price class.
Cost optimization
Isnta decision: Static delivery and event-driven private operations avoid a conventional always-running content application. Optional AI cost is separated from delivery.
Customer responsibility: Owners must set budgets, measure their actual request and generation volumes, and review service pricing.
Sustainability
Isnta decision: Precomputed output, caching, limited JavaScript, and event-driven work reduce unnecessary computation and transfer.
Customer responsibility: Owners must measure rather than claim environmental outcomes and continue reducing avoidable processing and page weight.
