3. Prioritise Initiatives
Evaluate opportunities based on:
- Impact: Potential savings amount
- Effort: Time and resources required
- Risk: Potential service or capability impact
- Speed: Time to realise benefits
Quick Wins Strategy: Start with high-impact, low-effort opportunities to build momentum and demonstrate value whilst planning larger optimisation initiatives.
Infrastructure Optimisation
1. Eliminate Waste
Unused Resources
- Orphaned storage volumes and snapshots
- Unattached IP addresses and load balancers
- Decommissioned but still-running instances
- Non-production environments running 24/7
- Duplicate or forgotten test environments
Expected Savings: 10-25%
Typical organisations have 15-30% unused resources
Action Plan
- Tag all resources with owner, purpose, and lifecycle
- Identify resources without tags or unrecognised owners
- Implement automated cleanup policies
- Schedule non-production environments to shut down outside business hours
- Review and decommission quarterly
2. Rightsizing Strategy
CPU and Memory Optimisation
- Analyse actual utilisation vs provisioned capacity
- Identify consistently underutilised resources (<40% average)
- Downsize instances to match actual workload
- Use auto-scaling instead of over-provisioning
Storage Optimisation
- Move infrequently accessed data to cheaper storage tiers
- Implement lifecycle policies for automatic tiering
- Enable compression and deduplication
- Delete old snapshots and backups per retention policy
Expected Savings: 15-30%
Most workloads are over-provisioned by 40-60%
3. Commitment-Based Discounts
Reserved Instances / Savings Plans
- Analyse usage patterns for stable workloads
- Purchase reserved capacity for predictable baseline
- Use spot/preemptible instances for non-critical workloads
- Review and adjust commitments quarterly

Operational Efficiency
1. Reduce Incident Costs
Why This Matters
Incidents are expensive beyond immediate downtime costs:
- Engineering time for troubleshooting and resolution
- Opportunity cost of delayed feature development
- Technical debt from quick fixes
- Customer support and communication overhead
£150K+ Annual Savings
Reducing incident frequency by 40% and MTTR by 60%
Strategies
- Implement Observability: Detect issues before customer impact
- Automate Detection: Replace manual monitoring with intelligent alerts
- Enable Self-Service: Developers troubleshoot without specialist help
- Post-Incident Reviews: Prevent recurrence through root cause fixes
2. Process Automation

Implementation Approach
- Identify repetitive, time-consuming processes
- Document current manual workflows
- Start with highest-frequency, highest-time activities
- Build automation incrementally with proper testing
- Measure time saved and error reduction
3. Productivity Improvements
Developer Efficiency
- Reduce Context Switching: Minimise interrupt-driven work
- Self-Service Tools: Enable independence from platform teams
- Better Tooling: Invest in productivity-enhancing tools
- Technical Debt Reduction: Eliminate ongoing friction
Productivity Example: A 30% productivity improvement for a 50-person engineering team at £100K fully-loaded cost = £1.5M annual value.
Architecture Optimisation
1. Service Consolidation
Opportunity Assessment
- Identify redundant or overlapping services
- Analyse inter-service communication patterns
- Find underutilised microservices (could be combined)
- Review legacy services with minimal business value
Benefits
- Reduced infrastructure and operational costs
- Simplified architecture and lower cognitive load
- Fewer points of failure and easier troubleshooting
- Reduced network overhead and latency
2. Database Optimisation
Cost Reduction Strategies
- Right-size database instances based on actual load
- Implement read replicas to reduce primary instance load
- Use appropriate storage types (SSD vs HDD)
- Archive historical data to cheaper storage
- Optimise queries to reduce compute requirements
- Implement caching to reduce database calls
Expected Savings: 20-35%
Database costs through rightsizing and caching
3. CDN and Caching Strategy
Cost Reduction Through Caching
- Reduce origin server load and costs
- Lower bandwidth costs through edge caching
- Decrease compute requirements for static content
- Improve performance whilst reducing spend
Implementation Priorities
- Identify high-traffic, cacheable content
- Implement application-level caching (Redis/Memcached)
- Enable CDN for static assets
- Cache API responses where appropriate
- Set optimal cache TTLs based on content update frequency
4. Multi-Region Strategy Review
Cost-Benefit Analysis
Multi-region deployments significantly increase costs. Evaluate necessity:
| Reason |
Justified? |
Alternative |
| Disaster Recovery |
Often Yes |
Active-passive instead of active-active |
| Low Latency |
Depends |
CDN + strategic placement |
| Data Residency |
If required |
Hybrid approach |
| "Best Practice" |
Rarely |
Single region with proper HA |
Cost Reality: Multi-region deployments typically cost 2-3x single-region with added complexity. Only implement when business requirements genuinely demand it.
Vendor Management
1. Software Licence Optimisation
Audit Current Licences
- Catalogue all software subscriptions and licences
- Track actual usage vs purchased seats/capacity
- Identify unused or underutilised licences
- Review tier/plan appropriateness
- Consolidate overlapping tools
Common Waste Areas
- Shadow IT: Unauthorised subscriptions (often duplicative)
- Legacy Tools: Replaced but not cancelled subscriptions
- Seat Bloat: Licences for departed employees
- Over-Provisioning: Enterprise tier when standard would suffice
- Multiple Tools: 3-4 monitoring tools when 1-2 would do
Expected Savings: 15-25%
Software spend through licence optimisation
2. Contract Renegotiation
Timing Strategy
- Begin renewal discussions 6 months before contract expiry
- Leverage competitive alternatives in negotiations
- Bundle renewals for better volume discounts
- Request customer success programmes in lieu of discounts

Questions to Ask Vendors
- What discounts are available for multi-year commitments?
- Can we receive credits for referring other customers?
- What's your renewal pricing policy? (Lock in rates)
- Are there cost optimisation features we're not using?
- Can we adjust our plan mid-contract if needs change?
3. Vendor Consolidation
Benefits of Consolidation
- Volume discounts across product portfolio
- Reduced integration and maintenance complexity
- Single support relationship and escalation path
- Unified security and compliance posture
Consolidation Candidates
- Monitoring and observability tools
- Security and compliance platforms
- Development and collaboration tools
- Customer communication platforms
Caution: Balance consolidation benefits against vendor lock-in risks. Maintain strategic optionality for critical systems.
Avoiding Cost-Cutting Pitfalls
1. Don't Cut Strategic Investments
Dangerous Cost Cuts
- Security Tools: Vulnerability creates much higher costs
- Observability: Blindness increases incident costs and duration
- Backup and DR: Data loss events are catastrophic
- Training: Knowledge gaps reduce productivity and increase errors
- Technical Debt Work: Debt compounds, increasing future costs
2. Maintain Service Quality
Red Flags
- Increased incident frequency or duration
- Customer complaints about performance or reliability
- Engineers spending more time firefighting
- Delayed feature delivery or innovation slowdown
- Key personnel departures due to technical frustration
Protective Measures
- Establish and monitor key quality metrics
- Maintain SLA buffers (don't optimise to the edge)
- Test cost changes in non-production first
- Have rollback plans for optimisation initiatives
- Listen to engineering team concerns
3. Account for Hidden Costs

4. Sustainable vs Short-Term Cuts
Sustainable Optimisation
- Removes waste without impacting capability
- Improves efficiency and reduces costs simultaneously
- Creates repeatable, ongoing optimisation processes
- Builds organisational capability
Harmful Short-Term Cuts
- Reduces capability or capacity needed for strategy
- Creates technical debt requiring future investment
- Increases operational risk or incident likelihood
- Damages team morale and productivity
Principle: Optimise for total cost of ownership over 3 years, not just immediate budget impact. Consider second-order effects.
