| Troubleshooting | L37-L53 | Diagnosing and fixing MySQL Flexible Server issues: connectivity, performance (CPU/memory/queries), capacity, corruption, replication latency, CLI errors, and using logs/self-heal tools. |
| Best Practices | L54-L71 | Best practices for monitoring, performance tuning, troubleshooting, safe operations, BCDR, and end-to-end migration/optimization for Azure Database for MySQL Flexible Server |
| Decision Making | L72-L90 | Planning MySQL on Azure: version lifecycle, capacity and tier selection, HA/BCDR, performance features, and migration/upgrade strategies and tools from on-prem or other MySQL. |
| Architecture & Design Patterns | L91-L98 | Patterns for connecting AKS to MySQL Flexible Server, designing backup/restore, data-in/out replication, high availability (zone-redundant), and read-replica-based scaling. |
| Limits & Quotas | L99-L107 | Limits, quotas, and performance caps for MySQL Flexible Server: max connections/cores/IOPS, storage IOPS behavior, quota increase requests, restart/stop limits, and delete/restore time limits. |
| Security | L108-L134 | Securing Azure Database for MySQL Flexible Server: network isolation (Private Link, firewalls), TLS and cert rotation, encryption, Entra auth, users, and audit logging before/after migration. |
| Configuration | L135-L165 | Configuring MySQL Flexible Server: HA, networking, replication, maintenance windows, monitoring/alerts, logging, server parameters, scaling, and point-in-time restore via portal and CLI. |
| Integrations & Coding Patterns | L166-L176 | Connecting to Azure Database for MySQL Flexible Server via CLI, Java/JDBC, Power BI, managing connection strings with Key Vault, and migrating data from RDS, on-prem, VMs, or Workbench |
| Deployment | L177-L186 | Automating MySQL Flexible Server deployments and changes (Azure Pipelines, GitHub Actions, Automation), handling backups, geo-restore, version upgrades, and scheduled maintenance. |
