Cloud native solutions

Let me scale your cloud native environments, preferred on AWS

Guiding principles

• Enablement of the developer community with guardrails, best practices and batteries included
• Maximum transparency and observability - costs, execution, bottlenecks
• Scalability in mind - from small teams to global execution of services
• Elasticity and cost control - scale up with cost optimisation in mind
• Measure everything
• ShiftLeft on Security

DevOps and Internal developer platform

• Infrastructure as Code and Terraform in CICD
• Automate everything!
• Internal OpenSource projects as a participation layer for eg. Terraform modules
• DevOps principles for product teams (you build it, you run it)
• GitOps for the win

FinOps

• Full cost observability
• Unlocking optimisation and savings
• Combining AWS and kubernetes workload costs

Observability and Alarming

• Collect Metrics and SLI
• Aggregate them into SLO and SLA
• Monitor and alarm on your SLO budgets
• Display the status of your system (technical and business perspective)

Developer Experience

• backstage.io as a central developer hub
  • Everything in code
  • Aggregating information across the landscape
  • OpenAPI integration, relationship documentation
  • Documentation hub
• Centralised artifact storage for re-use, scanning, access management
• Central CICD with common steps
• Meta-guild (see: Spotify Model) for top-down and bottom-up streamlining
• Common libraries and project templating - don’t solve the same problem twice

Building and scaling teams

• I structured, hired and lead 3 teams, mentored Engineering Leads, gave vision (tactical and strategic input)
• Focus on 4 Key Metrics (DORA metrics)
• Product driven development style even for infrastructure
