Back to all work
Designed cost-efficient delivery and cloud strategies
Sky operates premium streaming services with strict quality expectations and very high concurrent viewership during live events, making delivery cost a major operational concern.
CDN DeliveryVideo PackagingCost Optimization
The challenge
Delivery costs were growing faster than viewership, with inefficient cache behaviour, oversized renditions and suboptimal packaging contributing to wasted egress.
Our approach
- Reviewed the full packaging and ABR ladder against real viewership patterns.
- Tuned origin shielding and CDN cache keys to maximise hit ratios.
- Right-sized renditions and segment durations for efficient delivery without quality loss.
- Modelled cost impact of changes before rollout to de-risk migrations.
Outcomes
- Material reduction in CDN egress cost per viewer hour.
- Maintained or improved perceived video quality at scale.
- Cost model and playbook reusable across future titles and events.
