From Monolith to Cloud-Native — Without Starting Over

We refactor legacy applications into cloud-native architectures — containerized, scalable and designed to exploit the full capabilities of modern cloud platforms.

THE CHALLENGE

Lift-and-shift is not modernization

Many enterprises have moved workloads to the cloud — but they have not changed how those workloads run. A monolithic .NET application running on a virtual machine in Azure is still a monolith. It does not auto-scale. It does not self-heal. It does not leverage managed services. The cloud bill grows but the architecture remains the same, and the operational burden has simply shifted from your data center to a cloud console.

Cloud-native refactoring means redesigning applications to take advantage of what the cloud actually offers: auto-scaling, managed databases, event-driven compute, container orchestration and global distribution. It is the difference between renting a server in someone else is data center and building software that is genuinely cloud-native.

OUR APPROACH
01

Assess & Plan

We analyze the existing application architecture, identify components suitable for containerization, serverless or managed services, and define a refactoring roadmap with clear milestones.

02

Refactor & Containerize

We refactor application components following 12-factor principles, containerize with Docker, implement health checks, structured logging and configuration externalization.

03

Deploy & Optimize

Kubernetes deployment with auto-scaling, self-healing and rolling updates. Cost optimization through right-sizing, spot instances and serverless offloading of appropriate workloads.

CAPABILITIES

What we deliver

Containerization

Packaging applications into Docker containers with optimized images, multi-stage builds and security scanning. From development parity to production readiness in a repeatable pipeline.

12-Factor Compliance

Refactoring applications to follow 12-factor principles: externalized configuration, stateless processes, port binding, disposability and dev-prod parity. The foundation for cloud-native operation.

Kubernetes Orchestration

Deployment to managed Kubernetes (AKS, EKS, GKE) with proper resource management, health probes, horizontal pod autoscaling, service mesh and ingress configuration.

Serverless Offloading

Identifying components that benefit from serverless execution: event processors, scheduled jobs, API endpoints with variable traffic. Reducing operational overhead and cost for appropriate workloads.

Managed Service Adoption

Replacing self-managed infrastructure components with cloud-managed equivalents: managed databases, message queues, caches and search services. Reducing operational burden while improving reliability.

AXA Partners

CHALLENGE

AXA Partners ran a claims processing application as a monolithic .NET service on virtual machines. It could not scale for seasonal demand spikes and required manual intervention for every deployment.

APPROACH

We decomposed the monolith into containerized microservices, deployed on AKS with horizontal pod autoscaling, implemented a CI/CD pipeline and offloaded document processing to Azure Functions.

RESULT

Auto-scaling handles 5x traffic spikes without manual intervention. Deployment frequency increased from monthly to daily. Infrastructure costs reduced by 35% through right-sizing and serverless offloading.

FAQ

Common questions about cloud-native refactoring

What is the difference between lift-and-shift and cloud-native refactoring? +

Lift-and-shift moves the application to the cloud without changing its architecture — you get cloud hosting but not cloud benefits. Cloud-native refactoring redesigns the application to leverage auto-scaling, managed services, containers and event-driven patterns. The operational model and cost profile fundamentally change.

Do we need to rewrite the entire application? +

No. We take an incremental approach — identifying components that benefit most from refactoring and tackling them first. Some parts of your application may be fine as containers with minimal changes. Others may need decomposition into microservices. We prioritize based on business value and technical feasibility.

How do you handle stateful components during containerization? +

Stateful components require careful handling. We externalize state to managed services (Redis for session state, managed databases for persistence, blob storage for files). For components that must maintain local state, we use StatefulSets with persistent volumes in Kubernetes.

What are the typical cost savings from cloud-native refactoring? +

Most enterprises see 25-40% infrastructure cost reduction through right-sizing, auto-scaling (paying only for what you use) and serverless offloading. The bigger savings come from operational efficiency — fewer manual deployments, self-healing infrastructure and reduced incident response time.
