From legacy applications to future-ready architectures: How Skaylink approaches application modernization
Lead Solution Architect
Most organizations know that parts of their application landscape need to evolve. The challenge isn’t recognizing the need for modernization; it’s knowing where to start, which applications should be prioritized, and how to translate technical discussions into business cases that leadership can act on.
At Skaylink, application modernization starts with understanding the current application landscape, the business value of each system, the risks of legacy architectures, and the opportunities offered by cloud-native services, automation, and AI. From there, we guide customers from assessment to decision-making and implementation.
Why modernization has become a business priority
Legacy applications often carry risks that become particularly apparent when organizations need to adapt quickly: unsupported software versions, monolithic architectures, manual deployment processes, rising infrastructure costs, and limited scalability during peak demand. Meanwhile, customers and employees expect digital services to be fast, reliable, and continuously improving.
Modernization addresses these challenges by reducing operational risks, improving resilience and scalability, and lowering costs through infrastructure and license optimization. It also creates the foundation for new capabilities such as analytics, automation, and AI-based features. In other words, modernization is about more than just replacing old technology. It’s about ensuring applications can support what the business needs next.
How AI is changing the modernization business case
One of AI’s most significant impacts on application modernization is economic: it can substantially reduce the effort required and accelerate delivery. Tasks that consume considerable engineering time – such as analyzing large code bases, identifying dependencies, documenting business logic, or upgrading versions – can increasingly be supported or automated by AI-powered tools and agents.
Experienced architects and developers remain essential, but AI allows them to focus on higher-value decisions while automating repeatable modernization tasks. As a result, applications that were previously difficult to justify financially can become viable modernization candidates.
The Skaylink modernization journey: From qualification to execution
Skaylink follows a structured process that helps customers move from uncertainty to a clear modernization roadmap.
- Qualify: Understand business goals, application readiness, modernization objectives, and the overall portfolio.
- Assess: Take a closer look at the technical and organizational context. This may include source code analysis, database mapping, architecture review, and a Modernization Viability Assessment for selected applications.
- Modernize: Transform applications, data, and analytics services according to business goals. This can be done, for example, by adopting cloud-native architectures, managed databases, containers, DevOps automation, or AI-enabled capabilities.
What is an Application Modernization Assessment?
Our Application Modernization Assessment (AMA) is designed to answer a practical question: Which applications in the portfolio are the best candidates for modernization – and why?
The assessment considers business context, technical readiness, modernization potential, and financial considerations. It examines what an application does, why it matters, who uses it, how critical it is, and what value modernization could deliver.
The approach is cloud-agnostic and can be applied to any application portfolio, regardless of whether the customer uses AWS, another hyperscaler, or primarily operates on-premises. Skaylink is authorized by AWS as a partner to deliver Application Modernization Assessments and can help eligible customers take advantage of AWS funding throughout their modernization journey including assessment. This makes it possible to start with a structured, partner-led assessment, reduce upfront investment, and receive a clear business-oriented roadmap for modernization.
A structured 3-phase approach
The assessment spans three phases over approximately 10 days:
The resulting deliverables include a portfolio view that shows which applications warrant further consideration and where modernization is most likely to deliver value. Applications are compared based on criteria such as ease of modernization, business criticality, cost saving potential, architecture and dependencies, infrastructure fit, and recommended modernization pathways.
The assessment progressively narrows the scope to the most promising candidates while identifying applications for which modernization may not yet be justified.
For the most promising candidates, the next step is an in-depth Modernization Viability Assessment, which translates portfolio-level prioritization into a specific target architecture, project plan, and an executive-ready business case for an individual application.
What customers receive
- Application portfolio analysis: a structured overview of assessed applications, including scoring and prioritization
- Modernization readiness view: an evaluation of technical and business readiness based on factors such as complexity, criticality, and expected return
- Technology and dependency insights: visibility into infrastructure, databases, architecture, and modernization options
- Commercial perspective: a business-oriented view of potential cost savings, payback, and operational benefits
- Recommended next steps: clear guidance on which applications should undergo an in-depth Modernization Viability Assessment or proceed with a modernization project
