Are you getting the most from your AWS spend?

Most public sector organisations have already crossed the cloud adoption threshold. AWS is no longer experimental - it’s embedded in day-to-day operations. The challenge we’re seeing now isn’t whether organisations are using cloud. It’s whether they’re extracting the full value from it.

In a recent webinar with AWS and the University of Exeter, we explored what optimised cloud investment really looks like in practice. The discussion wasn’t about new features or technical roadmaps. It centred on governance, financial visibility and treating cloud as a managed institutional capability rather than an unpredictable line item.

That shift in mindset is what separates adoption from maturity.

From adoption to maturity

Early cloud journeys prioritise speed. Teams want flexibility, autonomy and rapid innovation - and cloud adoption enables that. But as environments grow, complexity grows with them. Without structure, organisations can end up with fragmented accounts, inconsistent security controls and unclear ownership of spend.

The institutions moving into cloud maturity are reframing AWS as shared infrastructure.

Mike Westwood from the University of Exeter described how centralising accounts and introducing organisational guardrails didn’t slow progress - it accelerated it. Security improved. Billing simplified. Onboarding new projects became faster. Teams moved from reactive firefighting to confident delivery.

As Mike explained, central governance allowed them to:

“Move from fragmented accounts to a governed structure with consistent security, central visibility and simplified billing.”

Innovation becomes easier when the foundations are stable. Mature cloud strategy isn’t about restriction; it’s about creating freedom within governance.

Visibility changes behaviour

You can’t optimise what you can’t see.

One of the strongest themes from the conversation was financial transparency. Exeter’s move toward near real-time visibility of AWS spend has reshaped internal accountability. Engineering, research and finance teams now work from the same data. Forecasting is more predictable. Costs can be attributed accurately. Optimisation becomes continuous rather than reactive.

As Mike put it during the session, FinOps turns AWS from an unknown expense into a managed institutional service.

That’s more than a technical improvement- it’s a cultural one. When cloud spend becomes visible and measurable, decision-making becomes strategic. Conversations shift from cost anxiety to informed planning.

Structured tagging of cloud resources plays a critical role in enabling that visibility. Good tagging discipline allows meaningful allocation across departments and projects while supporting compliance and security. Without it, visibility remains surface-level. With it, organisations gain operational intelligence.

Value beyond savings

Financial pressure is a reality across the sector, which is why collective agreements like the One Government Value Agreement (OGVA) are so significant. By treating the UK public sector as a single customer, organisations gain access to discounts, credits and training that would be impossible to negotiate individually.

For Exeter, sector-wide pricing was an important factor. But the value extended beyond cost reduction. Enhanced AWS support, access to sector expertise, architectural guidance and training created operational confidence.

Training is often underestimated in financial conversations. Upskilling internal teams strengthens retention, builds long-term capability and reduces dependency on external providers. In many cases, the training benefits alone approach the cost of participation.

Mike summed it up bluntly:

“The real question isn’t why sign up - it’s why wouldn’t you?”

Cloud as an institutional capability

The organisations seeing the greatest return are those treating cloud not as a collection of projects, but as a core institutional service. When cloud becomes governed infrastructure aligned with organisational strategy, it stops being an unpredictable expense and becomes a managed capability.

Optimisation isn’t a one-time exercise. It’s a continuous discipline built on visibility, accountability and governance. Partnerships play a crucial role in that journey- providing expertise, tooling and shared learning that remove friction and accelerate progress.

That’s not just good cloud management. It’s good organisational strategy.
