Case Study 11: Cloud Democratisation through Infrastructure as Code

Cross-Cloud Deployment with Pulumi IaC

• Implemented cross-cloud deployment using Pulumi Infrastructure as Code (IaC)

• Designed strongly-typed Pulumi Python packages and code-first configuration templates, enhancing misconfiguration detection

• Extended the existing PaaS product with "bring-your-own-cloud" capabilities, enabling users to deploy on their preferred cloud providers

• Accelerated deployment from weeks to just hours, significantly improving efficiency and time-to-delivery

Challenges

• Pulumi API Limitations: Generic cloud provider APIs lacked specific features, requiring custom abstractions

• Code and Configuration Trade-Off: Balancing concise, readable configurations with clean, maintainable deployment code

Implementation Specifics

• Pulumi: Core tool for Infrastructure as Code

• Python: For creating strongly typed Pulumi packages and templates

• Cloud Platforms: AWS, ScaleWay, Azure for multi-cloud deployment

• Docker Swarm: Orchestrating containerized environments for the PaaS extension
