How We Differentiate Our Modernization Assessment
At Romexsoft, we turn technical analysis into controlled, executable change with clear priorities, ownership, and measurable platform improvements.
Proven AWS Competence
As an AWS Advanced Tier Services Partner, we deliver assessments led by certified engineers with real production experience. Our recommendations ensure all key decisions are aligned across Well-Architected Framework, Cloud Adoption Framework, and Architecture Patterns.
MVP-Led Strategy
We prioritise 2-3 realistic modernization initiatives instead of proposing full rewrites. Each initiative is tied to measurable improvement. This creates momentum without destabilising the platform service delivery.
Clear Accountability
Each identified risk, modernization initiative, and architectural decision is mapped to responsible roles and execution checkpoints. This prevents recommendations from becoming abstract proposals without follow-through.

Why Consider an Application Modernization Assessment?
Many companies scale on architectures not built for current demand, complexity, or security needs. The result is slower releases, recurring incidents, and rising cloud costs.
Scaling Pressure Exceeds Architecture Limits
Technical Debt Restricts Business Agility
Release Velocity Creates Instability
Incidents Repeat And Recovery Remains Slow
Cloud Costs Grow Without Coordinated Control
Security And Compliance Expectations Increase
How We Conduct the Assessment
Our evaluation approach provides a clear understanding of your current application state, identifies proven modernization opportunities, and converts findings into actionable steps. If you decide to move forward, we can act as your app modernization partner, implementing the roadmap while maintaining a consistent architectural direction.
This is the starting point of the journey which focused on establishing a complete picture of the current system technically and operationally.
- Deep dive into application
- Understand pain points and challenges
- Go through the existing documentation
– Review overall software architecture
– Analyse infrastructure setup and AWS usage
– Map integrations, attachments, and data flows
– Assess CI/CD pipelines and release processes
– Identify scalability bottlenecks and performance issues
– Review incident history and operational instability
– Surface security, compliance, and governance gaps
– Capture product and business constraints affecting architecture
– Review architectural diagrams and tech specifications
– Analyse deployment procedures and operational runbooks
– Validate documentation accuracy against the actual environment
– Identify undocumented vulnerabilities or dependencies
The output of this stage is an application baseline report: what exists today, where the weaknesses are, and which constraints must be considered during the modernization.
Based on the current-state picture, we identify high-impact modernization opportunities that balance technical improvement with business value.
- Identify MVP opportunities
- Match to pathways
- Create target architectures
– Define modernization initiatives that can deliver measurable impact
– Select candidates for modularisation, containerisation, or refactoring
– Evaluate quick wins that reduce operational risk or cost
– Align MVP scope with business priorities and resource availability
– Determine appropriate modernization strategy
– Align initiatives with AWS best practices
– Evaluate trade-offs between speed, cost, and flexibility
– Ensure each direction supports scalability and reliability goals
– Design high-level planned architecture diagrams
– Define infrastructure components and service boundaries
– Establish security, networking, and observability design principles
– Outline migration sequencing and dependency management
The output is a defined modernization vector: which initiatives to prioritize, which pathway fits each case, and what the target architecture should look like to support the execution.
The result of these works is a confirmed modernization plan: agreed findings, clarified assumptions, and harmonised moves for enabling smooth transition to delivery.
- Present the outcomes of assessment
- Follow up with open questions

Our Modernization Assessment Deliverables
Throughout the assessment, we deliver artifacts that support decision-making, budget planning, and risk control with clear, evidence-based insights.
Application Readiness Score
A deep analytical overview of app inventory, critical system influences, integration points, data flows, single points of failure, and functional concerns. Using the map, we clarify how components interact, where changes may trigger cascading impact, and where structural weaknesses exist. It supports informed prioritization of modernization initiatives with full awareness.

It supports informed prioritization of modernization initiatives with full awareness.
AWS Reference Architecture
Our Solutions Architect design the architectural blueprint that aligns with Amazon Web Services best practices. It defines future service boundaries, the modularisation approach, core infrastructure, networking model, security structure, as well as observability and resilience principles. The reference architecture establishes a technically ground for further modernization.
Phased Implementation Roadmap
A structured plan that turns assessment findings into an executable sequence of work. There we outline 2-3 prioritised MVP initiatives, the actions that reduce risk early, the follow-on improvements to strengthen the platform, and the longer-term milestones that complete the whole path. The roadmap is sequenced to support progress without disruption.
Effort and Cost Estimate
A FinOps Analyst conducts the high-level estimation model that translates the roadmap into planning numbers. It outlines expected engineering effort by phase, the likely infrastructure impact, migration complexity drivers, and where cost optimization is achievable. It gives decision-makers a clear basis to compare options, plan budgets, and commit to delivery with fewer unknowns.
Benefits of Application Modernization Assessment
Rather than relying on assumptions, the evaluation provides structured insight into system readiness, modernization options, and the potential impact of architectural changes.
Architectural Clarity
Alignment with Cloud Best Practices
Technical Exposure
Clear Evolution Direction
Modernization Assessment FAQ
What happens during the Architecture Sessions?
During the Architecture Sessions, we work with your team to design target architecture options aligned with selected modernization approaches. These proposed designs are validated against AWS Well-Architected Framework pillars to ensure they meet requirements for reliability, performance efficiency, security, cost optimisation, and operational excellence before moving forward with the roadmap.
Will this assessment require any interventions to our current production environment?
No. The assessment is focused on reviewing your current architecture, infrastructure setup, delivery processes without introducing changes to live systems. All activities are limited to analysis, workshops, and planning, allowing your production environment to continue operating as usual throughout the process.
Can our team perform a self-assessment without involving an AWS Partner such as Romexsoft?
It is possible to conduct an internal review using AWS assessment tools. However, without involving an AWS Partner, organizations may face limitations in validating architectural assumptions, evaluating modernization trajectories, and identifying hidden governance risks.
Engaging with us brings an unbiased and competent engineering perspective, engineering-led delivery experience, and alignment with AWS best practices, helping ensure that findings translate into an actionable and development-related modernization roadmap.
Do all required stakeholders need to attend the assessment workshop?
While assembling the full list of critical stakeholders can be challenging, their participation helps establish a shared understanding and ensures accurate input across business, application, and runtime domains. The workshop can be tailored to fit organisational availability, and if full attendance is not possible, it is important to assign a single-threaded owner who can coordinate input from the right teams when needed.
