The Old Core is Crumbling: Why Banks Are Desperate for Cloud-Native Infrastructure
As customer expectations soar and competitive pressure mounts, banks are waking up to a hard truth — their legacy core systems are holding them back. The traditional monolithic infrastructure that once supported decades of growth is now a bottleneck to innovation, agility, and resilience.
In 2025, banks aren’t just modernising — they’re rebuilding. The shift to cloud-native, composable infrastructure is no longer a plan; it’s a reality. It’s an urgent priority.
At the NexGen Banking Summit – UK Edition (October 15–16, London), leaders from top institutions, including Barclays, HSBC, JPMorgan, and Lloyds, will discuss how they’re replacing outdated cores with cloud-first platforms designed for speed, flexibility, and scalability.
If your company builds cloud banking platforms, DevOps tooling, or core modernisation frameworks, this is your moment.
Why Legacy Core Banking No Longer Works
Legacy systems are:
- Expensive to maintain
- Inflexible in adapting to new customer journeys
- Poorly integrated with real-time APIs, open banking, and GenAI
- Vulnerable to outages and costly downtime
Banks are losing time and margin with every patch, workaround, and integration layer. As digital-first competitors and fintechs scale with modular infrastructure, traditional banks are left stuck in waterfall processes and siloed data.
Modern banking demands core systems that are:
- API-first
- Cloud-native
- Modular and composable
- Designed for real-time data
The Shift to Cloud-Native Platforms
Increasingly, banks are issuing RFPs that require cloud-ready architecture — not just lift-and-shift hosting, but reimagined ecosystems. Platforms like Mambu, Thought Machine, 10x, and Finxact are gaining traction for their ability to spin up products in weeks, not months.
We’re seeing large-scale moves like:
- Tier-1 banks migrating key workloads to public and hybrid cloud environments
- Digital-only subsidiaries (e.g., Chase UK, Marcus by Goldman Sachs) are being built entirely on cloud cores
- Composable banking models enabling plug-and-play onboarding, lending, and payments modules
This opens the door for a new class of vendors: core infrastructure innovators, DevSecOps enablers, container orchestration platforms, observability tools, and cloud compliance frameworks.
Real-World Impact
By adopting cloud-native core solutions, banks are achieving:
- 80% reduction in time-to-market for launching new digital products
- 50% lower infrastructure costs with elastic scaling
- Near-zero downtime and superior disaster recovery with multi-cloud resiliency
- Streamlined integrations with GenAI tools, RegTech APIs, and open banking layers
These gains are no longer theoretical — they’re being presented live by banking CTOs, CIOs, and Heads of Transformation at NexGen Banking Summit 2025.
