The Cloud Cost Challenge#

Cloud ERP promised lower costs through pay-as-you-go pricing. The reality is more complex. Without active cost management, cloud ERP costs often exceed expectations. The flexibility that makes cloud attractive also makes it easy to overspend.

The cost management imperative: Every dollar spent on cloud infrastructure is a dollar not spent on business initiatives. Effective cost optimisation ensures your cloud investment delivers maximum value.

Cost Optimisation Strategies#

Right-Sizing#

Application servers: - Monitor utilisation - Match instance types to workload - Scale down during low-usage periods

Database: - Right-size database instances - Optimise storage allocation - Use appropriate storage tiers

Reserved Capacity#

Commitment discounts: - Reserved instances (1-3 years) - Savings plans - Committed use discounts

When to reserve: - Stable workloads - Predictable growth - Long-term commitment

Storage Optimisation#

Data tiering: - Hot data on premium storage - Warm data on standard storage - Cold data on archive storage

Data management: - Regular data archival - Backup retention policies - Log rotation

Network Optimisation#

Reduce data transfer: - Optimise integration traffic - Use caching strategically - Compress data transfers

Licensing Optimisation#

User licensing: - Audit user activity - Reassign inactive licences - Optimise user types

Module licensing: - Review module usage - Disable unused modules - Negotiate volume discounts

ANZ-Specific Cost Considerations#

Currency Risk#

Most cloud providers price in USD: - Exchange rate fluctuations - Currency hedging - Local pricing negotiation

Data Transfer Costs#

Cross-region: - Transfer between ANZ regions - Transfer to global regions - CDN configuration

Support Costs#

Premium support: - ANZ coverage requirements - Response time SLAs - Support tier optimisation

---

Cost Management Process#

Visibility#

Cost allocation: - Tag all resources - Allocate costs to departments - Track costs by project

Reporting: - Daily cost dashboards - Monthly cost reports - Quarterly cost reviews

Optimisation#

Regular reviews: - Monthly right-sizing reviews - Quarterly reserved capacity analysis - Annual licensing review

Automation: - Automated scaling policies - Scheduled start/stop - Automated cleanup

Governance#

Policies: - Resource tagging requirements - Approval workflows for large resources - Cost anomaly alerts

---

Monday Morning Action Plan#

  1. Tag Your Resources: Implement comprehensive tagging for cost allocation.
  1. Review Current Costs: Analyse your current cloud spend by category.
  1. Identify Quick Wins: Find immediate optimisation opportunities.
  1. Implement Monitoring: Set up cost dashboards and alerts.
  1. Plan Reserved Capacity: Evaluate reserved capacity for stable workloads.

Conclusion: Cost Optimisation Is Continuous#

Cloud cost optimisation is not a one-time exercise—it's an ongoing process. The most successful organisations build cost awareness into their culture and processes, ensuring cloud delivers sustained value.
