Akkodis Application Modernisation – Transform

Akkodis Application Modernisation – Transform rearchitects, rebuilds or replaces an application to unlock business capabilities the current architecture cannot deliver. Unlike Uplift, the application doesn't end up doing the same thing on a better foundation — it ends up doing something different, with a fundamentally different shape.

Transform is the right pathway when the existing architecture is the constraint: when delivery cycles are too slow, when integration patterns block new business models, when the platform can't scale to where the business is heading, or when end-of-life software needs replacing rather than preserving.

Common transform scenarios

• Legacy client-server to cloud-native web — replacing thick-client or terminal-based applications with cloud-native web applications on AWS
• Monolith decomposition — breaking a monolithic application into services with clear boundaries, independent deployment and resilient integration
• Serverless rearchitecture — rebuilding workloads as event-driven, serverless solutions on AWS Lambda, Amazon EventBridge and managed data services
• End-of-life software replacement — replacing vendor software that has reached end-of-life with a purpose-built application aligned to current business needs
• Data and integration modernisation — redesigning data flows, APIs and integration patterns to support modern delivery and analytics
• Bespoke build to replace package gaps — building targeted custom applications to fill capability gaps left by packaged software

How we work

Akkodis consultants and engineers drive the work end-to-end, with AI tooling embedded in our delivery method to accelerate requirements extraction, architecture design, code generation, test creation and validation across the project lifecycle. AI enhances and augments our delivery to accelerate time to value and reduce cost — it does not replace the senior architectural and engineering judgement required to deliver new applications safely.

Typical engagement shape:

• Confirm scope — validate the transformation target, success criteria, business outcomes and migration strategy (typically informed by a prior Modernisation Assessment)
• Design — target architecture across business, solution, integration, technology and security domains; UI design, data models, API contracts, security model
• Plan — modernisation roadmap, task breakdown, test strategy, test plan and test cases
• Execute — development and configuration tasks, automated unit testing, build and deployment artefact creation
• Validate — automated system, integration and regression testing; user acceptance support; performance and security verification
• Migrate and cutover — data migration where required, controlled cutover, parallel running where appropriate
• Operate — optional handover to Akkodis Managed Application Services

AI delivery method

Akkodis operates within isolated AI development environments with controlled access to approved AI services, designed to be compatible with strict data-handling and AI-use policies. Client codebases and materials remain segregated, with managed prompts, instructions and tooling under Akkodis governance.

Targets and technologies

Transform targets cloud-native applications on AWS — typically web applications on containerised or serverless platforms (Amazon ECS, Amazon EKS, AWS Lambda) backed by AWS-managed data services (Amazon Aurora, Amazon RDS, Amazon DynamoDB, Amazon OpenSearch Service). Front-end stacks are language-agnostic and selected to fit the workload. Hybrid configurations are supported where on-premises integration must persist.

How we deliver

Akkodis is an AWS Advanced Tier Services Partner. We bring senior delivery engineers — solution architects, software developers, database administrators, UI/UX designers and test engineers — supported by our AI-enabled delivery method. Engagements are typically structured as fixed-scope or phased delivery shaped by a prior Modernisation Assessment. The transformed application can transition into Akkodis Managed Application Services on AWS for ongoing operation.
