AWS Advanced Tier Services Partner
Application Modernisation Services
We modernize legacy applications, turning them into cloud-native solutions that are scalable, secure and ready for the future. Whether it is a monolith to be broken down into microservices, an on-premise infrastructure to migrate to the cloud, or a database to move onto managed services — we define the right strategy and execute it without interrupting the business.
Why modernize
Re-architecting legacy applications for the AWS Cloud
Monolithic applications, rigid on-premise infrastructures, expensive proprietary databases, releases that take weeks: these are the symptoms of technical debt that piles up costs and slows down innovation. Application modernization is not just a technical matter — it is a lever of competitiveness. It means releasing faster, scaling when needed, cutting infrastructure costs and freeing the team to work on what generates value.
Our approach
Legacy application modernization strategies
There is no one-size-fits-all approach. We assess every application and define the most effective strategy based on the context, the constraints and the business objectives.
Re-Architecting
From monolith to microservices
Redesign of the application architecture: from monolith to microservices, from servers to serverless. The most transformative approach, ideal for core applications that need to scale and evolve quickly.
Containerization
Docker & Kubernetes
Migration of applications into Docker containers orchestrated with Kubernetes (EKS, ECS). Standardized environments, repeatable deployments and portability across cloud providers.
Serverless Adoption
Pay-per-use & autoscaling
Migration to serverless services (Lambda, Fargate, API Gateway, EventBridge) to eliminate infrastructure management, pay only for actual usage and scale automatically.
Database Modernisation
License savings & performance
Migration from proprietary databases (Oracle, SQL Server) to cloud-native managed services: Aurora, DynamoDB, RDS, DocumentDB. Lower licensing costs and improved performance.
API Layer & Strangler Fig
Gradual modernization
A modern API layer on top of legacy systems to enable new integrations and frontends, modernizing gradually without rewriting everything. The strangler fig pattern makes it possible to migrate one piece at a time.
Lift & Shift + Optimization
Fast and progressive
Rapid migration of the on-premise infrastructure to the cloud (lift & shift), followed by a phase of progressive optimization: rightsizing, managed services, automation and incremental modernization.
How We Work
Our modernization process
A structured approach that starts from understanding the context and ends with the production rollout, with full visibility at every stage.
Assessment
Analysis of the application, technical debt, dependencies and constraints. We map the current state and identify modernization priorities based on business impact.
Strategy
We define the best approach for each component: re-architect, containerize, re-platform or lift & shift. We deliver a roadmap with clear milestones and mitigated risks.
Execution
We modernize in incremental phases, one component at a time. Each release is tested and validated before moving on to the next, ensuring business continuity.
Optimization
After migration, we optimize costs, performance and security. Active monitoring, resource rightsizing and automation of operational processes.
