How Santander Cut Provisioning Time from 90 Days to Hours with the Catalyst Platform

Santander’s Catalyst platform abstracts cloud infrastructure, enforces architectural standards, and accelerates service delivery for billions of daily transactions.

Core Architecture

The platform centers on an Amazon Elastic Kubernetes Service (EKS) control‑plane cluster that coordinates all workflows. Crossplane acts as a universal provisioner, enabling declarative resource management across multiple clouds.

  • Control‑plane cluster built on Amazon EKS for high availability.
  • Crossplane extensions translate internal policies into cloud‑native resources.
  • Unified API surface presented through an intuitive developer portal.
  • Support for AWS, Azure, and GCP via a single declarative schema.
  • Observability stack integrated with OpenTelemetry for end‑to‑end tracing.

Provisioning Workflow

Developers submit requests through the portal the system validates them against predefined architecture rules before triggering automated pipelines. This eliminates manual hand‑offs and reduces error rates.

  • Declarative YAML manifests define desired infrastructure state.
  • Policy engine checks compliance with standardized governance rules.
  • Crossplane creates resources on target clouds in a single transaction.
  • Automatic rollback on failure ensures safe deployments.
  • Provisioning time dropped from 90 days to under an hour.

Governance & Security

All resources inherit security baselines defined in the platform, providing consistent protection across environments. Auditing is baked into the pipeline to satisfy regulatory requirements.

  • Role‑based access control (RBAC) enforced at the control‑plane level.
  • Encryption‑at‑rest and in‑transit enforced by default.
  • Continuous compliance checks integrated with AWS Config.
  • Audit logs stored in immutable S3 buckets for forensic analysis.
  • Policy‑as‑code framework linked to security best‑practice guides.

Operational Benefits

The consolidated control plane replaces over 100 separate CI/CD pipelines, simplifying operations and freeing teams to focus on value‑adding work.

  • Provisioning cycle reduced from 30 days to 2 days for standard workloads.
  • Proof‑of‑concept setup time shortened from 90 days to 1 hour.
  • AI‑agent deployment time cut from 105 days to 24 hours.
  • Infrastructure tickets per environment dropped dramatically.
  • Unified monitoring dashboard provides real‑time health insights.

Cultural Impact

Catalyst introduced a self‑service mindset, encouraging developers to own their infrastructure while maintaining compliance. This shift improved delivery speed and adaptability to market changes.

  • Teams provision resources without waiting on central ops.
  • Training modules embedded in the portal accelerate onboarding.
  • Feedback loops from deployments feed directly into platform improvements.
  • Metrics show a measurable increase in development velocity.
  • Platform serves as a foundation for future digital initiatives.
