Modernizing Legacy Apps for the Cloud

Published April 2025

Modernizing legacy applications is more than just lifting and shifting them to the cloud. At CloudCraft Labs, we specialize in rearchitecting and replatforming legacy systems to fully leverage the power, flexibility, and scalability of cloud-native platforms.

Why Modernize?

• Reduce technical debt and maintenance costs
• Improve scalability and availability
• Enable CI/CD and DevOps best practices
• Integrate with modern SaaS and AI services

Our Approach

1. Assessment: Evaluate your existing application stack, performance, and dependencies.
2. Roadmap: Define a modernization strategy—whether it's refactoring, rehosting, or replatforming.
3. Execution: Rebuild core services as microservices, containerize with Docker, and orchestrate with Kubernetes or OpenShift.
4. Deployment: Automate with Infrastructure-as-Code, CI/CD, and integrate observability tooling.

Technologies We Use

• Docker & Kubernetes (AKS, EKS, GKE, OpenShift)
• Spring Boot, .NET Core, Python Flask
• Azure, AWS, GCP
• GitHub Actions, Jenkins, ArgoCD, Helm

Case in Point

We helped a financial institution modernize a COBOL-based backend, exposing APIs for integration with Oracle Banking SaaS, enabling real-time updates, resilience, and scaling on-demand—all with minimal downtime.
