Application DeepDive is a specific assessment of a single application. Various inputs are gathered through the assessment project resulting in the optimal Cloud infrastructure for a given application.

DeepDive covers four major areas and topics:

Application assessment is a guided interview(s) with key application owners to understand the current application. During the interview, various topics are discussed, for example, application and infrastructure architecture, security and performance requirements, operating model and lifecycle, or individual application components.

Cloud architecture provides individual possible target cloud architectures and designs. All designs are evaluated against the application assessment for viability and requirements. Typically, multiple target architectures are designed to cover standard migration strategies from Lift&Shift through Replatform to Rearchitecture. I focus on the modernization approach when possible, so the designs follow Cloud-Native design patterns.

Total Costs of Ownership provides financial data for comparison. Current On-Premises costs are always included in comparison with individual target Cloud architectures. TCO includes not only the standard infrastructure costs but incorporates additional inputs like license costs, application migration, refactoring costs, and shared services costs.

Risks and benefits are documented for existing and possible Cloud architectures, providing additional inputs for the final recommendation. Each identified risk or benefit is justified and aligned with the key application stakeholder.

Every workload is unique, but the key concepts and best practices apply to most workloads. AWS Well-Architected Framework provides a consistent approach for customers to evaluate architectures and implement scalable designs and helps you build secure, high-performing, resilient, and efficient infrastructure for various applications and workloads.

A Well-Architected Review is a multidimensional assessment focusing on six key pillars and helps you to identify any weak spots and provides you with recommendations for improvements.

Operational Excellence Pillar

The operational excellence pillar focuses on running and monitoring systems, and continually improving processes and procedures. Key topics include automating changes, responding to events, and defining standards to manage daily operations.

Security Pillar

The security pillar focuses on protecting information and systems. Key topics include confidentiality and integrity of data, managing user permissions, and establishing controls to detect security events.

Reliability Pillar

The reliability pillar focuses on workloads performing their intended functions and how to recover quickly from failure to meet demands. Key topics include distributed system design, recovery planning, and adapting to changing requirements.

Performance Efficiency Pillar

The performance efficiency pillar focuses on structured and streamlined allocation of IT and computing resources. Key topics include selecting resource types and sizes optimized for workload requirements, monitoring performance, and maintaining efficiency as business needs evolve.

Cost Optimization Pillar

The cost optimization pillar focuses on avoiding unnecessary costs. Key topics include understanding spending over time and controlling fund allocation, selecting resources of the right type and quantity, and scaling to meet business needs without overspending.

Sustainability Pillar

The sustainability pillar focuses on minimizing the environmental impacts of running cloud workloads. Key topics include a shared responsibility model for sustainability, understanding impact, and maximizing utilization to minimize required resources and reduce downstream impacts.
