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 lift-and-shift, replatforming, and refactoring (re-architect) migration patterns for moving workloads to the cloud. For each pattern describe the trade-offs in cost, risk, speed, operational complexity and long-term maintainability, and give an example workload suited to that pattern.

Create a proof-of-concept (PoC) plan to evaluate serverless vs containerized implementations for an event-driven workload expected to process 100k messages/sec at peak. Include success criteria, test methodology, cost/perf metrics to collect, and a go/no-go decision framework.

You're planning capacity for an upcoming product launch. Describe the inputs, modeling approach, safety buffers and validation steps you would use to estimate compute, network and storage needs prior to launch. Include how you'd plan for unknowns and scaling during the first 6 months.

Propose an observability KPI dashboard that serves both executives and engineers for a platform. List which metrics are on each view, suggested visualization types, dashboard refresh cadence, and alerting thresholds that avoid noise but catch critical regressions.

Describe a practical program to measure and reduce cloud spend across multiple teams. Include tools or telemetry you would deploy, tagging and showback strategies, autoscaling/rightsizing policies, and governance mechanisms to control runaway costs without blocking innovation.
