Why should you care?

Legacy-friendly build using containers, CI/CD, secrets vault, and cost-aware sizing.

# CloudVerse ERP nightly batch
# Jenkins on-prem triggers → push artifact to ACR
# AKS Job: erp-batch (toleration: workload=batch)
# VM scale set fallback for 16-core GL posting
# Secrets: Key Vault via managed identity
# Monitoring: batch duration alert if > 6h

What happened?

• Hybrid CI meets cloud runtime.
• Long jobs need retry, checkpoint, and alert if SLA missed.

Practice next

1. Containerize one batch job.
2. Schedule CronJob in AKS.
3. Pull DB creds from vault.
4. Split GL posting into queue workers.
5. Add dead-letter queue for failed rows.

Remember

Hybrid CI to cloud run. CronJobs + checkpoints. Vault for ERP creds.

CloudVerse month-end close

Finance needs books by 6 AM.

Outcome: Batch finishes 4:30 AM; alerts fired on one retried chunk.
