Application Modernization Readiness Roadmap & Design

Pellera’s Application Modernization Readiness Roadmap & Design is designed to help enterprises move from legacy architectures to modern, cloud-native solutions using AWS.

This offering is ideal for organizations planning to rehost, replatform, refactor, or rebuild their applications in the cloud but need expert guidance to build a clear and actionable strategy. It can be delivered as:

• A standalone Current State Assessment to build the business case for modernization • A bundled Readiness & Detailed Design package to jump-start actual migration

Pellera’s Modernization Methodology includes:

1. Current State Assessment • Interviews with application owners and stakeholders • Review of current architecture, tech stack, and configurations • Source code and database analysis • Review of functional, performance, security, and compliance requirements
2. Detailed Design • Platform selection and future-state architecture • App-to-app and infra dependency mapping • Modernization prioritization: Do Now, Do Next, Do Later • Creation of a migration roadmap aligned to business objectives
3. Proof of Technology (Optional) • Validation of selected modernization approach and tooling • Prototype deployment to demonstrate feasibility and mitigate risk

Key Benefits

• Clarity on modernization options and timelines • Tailored AWS-native roadmap and platform recommendations • Reduced risk and improved stakeholder alignment • Business case justification for modernization funding • Aligned with AWS Well-Architected Framework
