Scaling Developer Experience with AI, Security, and Lean Platforms

Overview

PlatformCon 2025 spotlighted the evolution of internal developer platforms (IDPs), the rising influence of AI on developer workflows, and strategies to scale platforms across diverse environments, from fast-moving fintechs to air-gapped military infrastructure. These eight sessions reflected a maturing platform engineering discipline that is increasingly focused on developer experience, security, scalability, and value delivery.

Key Themes and Takeaways

1. Beyond Shared Services

Talk: “Platforms Aren’t Yet-Another Common Services Layer”
This session challenged the misconception that platforms are merely collections of shared services. Instead, they were reframed as accelerators of software delivery, drawing analogies from industrial engineering and systems thinking. Speakers emphasized how platforms must prioritize economies of speed over cost savings, anchoring their design in developer outcomes, not abstractions for abstraction’s sake.

2. Platform Engineering’s Coming of Age

Talk: “Lessons from 2018 to 2025”
This historical deep dive traced the evolution of platform engineering from self-service APIs to an outcome-driven, AI-augmented discipline. Lessons learned include the shift toward Developer Success Teams, the death of “Field of Dreams” platforms, and the growing need to balance automation with empathy. Developer experience, not DevOps alone, is now the ultimate north star.

3. The Rise of Cloud Development Environments (CDEs)

Talk: “Optimizing Developer Workflows with CDEs”
Local dev setups are fading. In their place: policy-driven, scalable Cloud Development Environments (CDEs). Speakers detailed how infrastructure-as-code principles, compliance automation, and embedded AI agents are reshaping how developers interact with their environments, turning dev setup into a managed, secure service rather than a personal responsibility.

4. AI-First Platforms in Action

Talk: “How SIXT Transforms Their IDP ‘AI First’”
SIXT’s platform story exemplifies how to enable large engineering orgs to run AI workloads securely without deep infrastructure knowledge. Highlights included GPU-enabled golden paths, AI-powered interfaces, and managed storage pipelines. Their experience offers a blueprint for building platforms that abstract AI infrastructure without stifling innovation.

5. Lean Platforms: The Thinnest Viable Platform (TVP)

Talk: “Putting Your Platform on a Diet”
TVPs are gaining traction as teams learn that feature-rich platforms often grow into bloated liabilities. This session offered tactical advice for pruning unnecessary services, identifying platform bloat, and iteratively evolving platforms to remain developer-centric. Simplicity is now seen not as minimalism, but as strategic focus.

6. The Evolution of Developer Portals

Talk: “The Future of Portals”
Developer portals are evolving from cataloging tools to intelligent control planes. Powered by AI and deeper integrations, the modern portal is now a gateway to everything from CI/CD pipelines to observability. Talks stressed the importance of user experience, backend orchestration, and the growing role of portals in streamlining platform interaction.

7. Unlocking Business Value: The Route to Live Framework

Talk: “Lessons from £2Bn of Tech Spend”

ClearRoute’s RTL framework, based on analyzing £2B in engineering spend, identified critical bottlenecks and offered a structured path to improving software delivery. Featuring a case study with Commonwealth Bank of Australia, the session demonstrated how organizations can reduce defects by 75% and increase deployments 12x by optimizing their Route to Live. AI agents were positioned as the next major unlock in the delivery pipeline.

8. Platform Engineering in High-Security Environments

Talk: “When National Security Is at Stake”
Military and regulated environments present unique constraints: air-gapped systems, strict compliance, and limited visibility for developers. This talk explored how to design platforms with embedded security and observability, even when runtime environments are off-limits. Strategies like workload abstraction, multi-environment orchestration, and zero-trust design principles were showcased.

Why This Matters

As organizations scale their digital operations, platform engineering is becoming essential to delivering secure, scalable, and high-performing developer experiences. These talks reflected a clear trajectory: platforms must be lean, intelligent, and tailored to specific organizational needs. According to our research, developer productivity is increasingly defined by the quality of internal platforms, not just tools or cloud services. From AI integration to secure deployments, the platform is now the product behind the product.
