Well Architected Pillars Security: The ability to protect information, systems, and assets while delivering business value through risk assessments and mitigation strategies. Reliability: The ability of a system to recover from infrastructure or service failures, dynamically acquire computing resources to meet demand, and mitigate disruptions such as misconfigurations or transient network issues. Performance Efficiency: The ability to use computing resources efficiently to meet system requirements, and to maintain that efficiency as demand changes and technologies evolve. Cost Optimization: The ability to avoid or eliminate unneeded cost or suboptimal resources. Operational Excellence: The ability to run and monitor systems to deliver business value and continually improve supporting processes and procedures.

Scope of Portfolio Discovery and Analysis Application Portfolio Analysis • 47 production servers across 28 applications • 116 non-production servers from two data centers • Around 50T primary storage and 35T backup storage • Other LOBs’ assets are excluded due to proprietary broadcast systems. Proposal submitted for content archival and PVR solutions • Business case analysis for a go or no-go decision

Preserve the application dependency discovered through the tool to minimize risk 2. Migrate workloads with less business criticality • Generate quick wins with least disruptions • Acquire experience prior to moving critical workloads • Minimize migration complexity upfront 3.
