Operations, Reliability, and Cost Optimization
Operations, Reliability, and Cost Optimization tests whether you can run IBM Cloud workloads to agreed service levels while keeping spend visible and controlled.
Operate with signals
Instrument applications with IBM Cloud Monitoring and Log Analysis, and route platform audit events to Activity Tracker. Define SLOs and alert on symptoms such as error rate and latency, not only CPU. Use health checks on load balancers and configure autoscaling with sensible minimums.
Design for recovery
Set RTO and RPO per workload, then choose backup and replication. Use VPC backup for volumes, Object Storage versioning and lifecycle policies, and cross-region buckets for critical assets. Test restores; an untested backup is a hypothesis.
Control cost
Tag resources by application, owner, and environment, then use tagging for chargeback. Review billing and usage, set spending notifications, right-size overprovisioned instances, and use autoscaling schedules for predictable peaks.
Worked example
A monthly bill jumps after a new service launches. Reasoning: filter billing by tags, identify the resource group and service, check Object Storage growth and lifecycle rules, confirm autoscaling maximums, then set a spending notification. Do not delete audit logs or backups to cut cost.
Traps
Optimizing cost before reliability; ignoring data transfer and cross-zone charges; autoscaling without load balancer health checks; leaving stale resources; deleting logs needed for compliance.
