Technical Vision and Infrastructure Roadmap Questions

This topic assesses a candidate's ability to define a multi year technical vision for infrastructure, platform, and systems and to translate that vision into a practical execution roadmap. Core skills include evaluating technology choices and architecture evolution, planning migration and modernization paths, anticipating scalability and capacity needs, and balancing cost performance with resilience and operational reliability. Candidates should demonstrate approaches to managing technical debt, sequencing investments across quarters and releases, estimating resources and timelines, establishing measurable infrastructure goals and key performance indicators, and implementing governance and standards. Discussion may also cover reliability and observability, security and compliance considerations, trade offs between short term stability and long term rearchitecture, prioritization to enable business outcomes, and communicating technical trade offs to both technical and non technical stakeholders.

Explain the difference between a strategic multi-year infrastructure roadmap and a tactical backlog of operational tasks. Give concrete examples of items that belong to each, and describe an approach to keep them aligned so short-term work does not derail long-term modernization goals.

Provide Terraform HCL snippets (ConstraintTemplate and Constraint) that implement a policy-as-code enforcement using Open Policy Agent Gatekeeper to reject any attempt to provision an S3 bucket with public access. Show the essential fields for the ConstraintTemplate and one Constraint example.

Sketch in Python (pseudocode acceptable) an algorithm to estimate cloud cost impact given a forecast of CPU hours, storage growth by month, and tiered pricing across providers including reserved/discounted rates. Show the input schema, explain how you model tiered pricing and reserved discounts, and include a simple computation for total monthly cost.

Write a Python script (pseudocode is acceptable) that implements an automated runbook to safely roll back a Kubernetes Deployment to the previous revision. The script should: verify the current deployment's replica status, perform the rollback, wait for pods to reach readiness, validate health endpoints across replicas, and include idempotence and basic error handling. Outline assumptions about kubeconfig and permissions.

Devise a mechanism to prioritize infrastructure investment requests across competing objectives: cost savings, resilience improvements, and scalability. Propose scoring criteria, weighting, and a decision process that ties priority to measurable business outcomes and risk reduction. Give a worked example for three hypothetical projects.
