NatWest Group (Royal Bank of Scotland)

Needs

NatWest required a standardised and accelerated method for deploying multi-cloud (AWS, Azure, GCP) landing zones. This included creating reusable Infrastructure as Code (IaC) templates to ensure consistency, security, and compliance for diverse data services and Kubernetes environments.

Solution

We delivered a Terraform Accelerator programme, providing IaaS and PaaS landing zone scripts and documentation.

• Data Solution:
  Standardised deployment patterns for AWS data services (Aurora, RDS, DynamoDB, Redshift) and Google Cloud data services (Cloud SQL, Bigtable, BigQuery, GCS, Cloud Spanner).

• Integration Solution:
  Defined standards for integrating AWS microservices and Google Apigee. Terraform scripts managed via Jenkins, GitHub, and Visual Studio, with IAM policies governed via G-Suite/Google Workspace.

• Data Science Solution (Operational Analytics):
  The defined standards for deploying and managing complex data services and Kubernetes (GKE, AKS, EKS) clusters laid the foundation for operational analytics and efficient resource management across clouds.

Achievements

• Multi-Cloud Terraform Landing Zones:
  Delivered standardised IaC for AWS, Azure, and GCP.

• Data & Kubernetes Standardisation:
  Defined deployment patterns for key database services (AWS & GCP) and Kubernetes (GKE, AKS, EKS).

• Governance & Automation:
  Established architecture rules and policy management for Terraform scripting and IAM.

Benefits

• Accelerated Cloud Adoption:
  Faster provisioning of secure and compliant multi-cloud environments.

• Increased Consistency:
  Ensured uniform configurations across AWS, Azure, and GCP.

• Reduced Manual Effort:
  Automated infrastructure deployment through Terraform.

• Scalable Foundation:
  Provided a robust base for future cloud-native applications and data analytics initiatives.
