Infrastructure Modernization and Cloud Adoption Questions

Covers the end to end process of modernizing an organization infrastructure and adopting public and private cloud platforms. Interviewers assess experience managing traditional data centers and virtualization platforms including capacity planning, power and cooling considerations, hardware refresh cycles, and operational excellence practices. It also includes planning and executing migrations and hybrid architectures, choosing between infrastructure as a service, platform as a service, and software as a service, and selecting cloud native patterns such as containerization, microservices, and serverless where appropriate. Candidates should be able to describe strategy development for organizations with legacy and new systems, cost and risk trade offs, security and compliance impacts, networking and connectivity for hybrid setups, data migration approaches, rollback and cutover techniques, and how infrastructure as code and automation practices support a modernization roadmap.
