The Cloud Cost Paradox
Cloud computing was supposed to save money. And it can — when managed properly. But without governance, cloud bills can escalate quickly, often exceeding what on-premises infrastructure would have cost. The key is optimisation, not just migration.
Common Cost Traps
- Over-provisioning: Running larger VM sizes than your workloads require
- Zombie resources: Forgotten VMs, unattached disks, and unused IP addresses
- Lack of scheduling: Development environments running 24/7 when they're only used during business hours
- Egress charges: Unexpected data transfer costs between regions and services
Optimisation Strategies
Rightsizing
Analyse actual resource utilisation and downsize over-provisioned instances. Most workloads run at under 30% CPU utilisation — that's money on the table.
Reserved Instances & Savings Plans
For predictable workloads, committing to one or three-year reserved instances can save 30–60% compared to on-demand pricing.
Tagging & Cost Allocation
Implement a consistent tagging strategy to track costs by department, project, and environment. You can't optimise what you can't measure.
