Core & Cloud Architecture Modernization
We drive the transition from legacy systems to scalable and resilient cloud environments.
In environments where legacy systems limit agility and increase costs, modernization becomes essential. At Crombie, we craft solid strategies to minimize risks, optimize systems, and migrate your core to a scalable cloud architecture.
The challenges we tackle
Difficult-to-scale monolithic systems
Security and compliance risks in legacy environments
Rising costs of on-premise infrastructures
Difficulty integrating APIs and new data channels
Low availability and slow response times

Software solutions aligned with your industry
Lift-and-Shift Migrations and Replatforming
We audit and migrate workloads to the cloud with minimal downtime. We replatform services to PaaS to reduce costs and complexity.
Containerization and Orchestration
We dockerize applications and manage Kubernetes clusters. We implement automated deployments and frictionless horizontal scaling.
Serverless and event-driven
We develop serverless functions that respond to real-time events. Resources are optimized so you only pay for actual usage.
Infrastructure as Code (IaC)
We define and version infrastructures using Terraform or CloudFormation, ensuring reproducible and auditable environments across the entire cycle.
Proactive Observability with AI
We implement comprehensive monitoring of logs, metrics, and traces. AI detects anomalies and recommends fixes before critical failures occur.
Core & Cloud Architecture Modernization Use Cases
Seamless Migration of Critical Systems
We help migrate monolithic architectures to the cloud with minimal operational impact. In recent projects, we reduced planned migration times by 50% while maintaining continuity for critical banking systems through a phased approach and automation tools.
On-demand Scaling for Traffic Peaks
We design resilient architectures that absorb traffic peaks during campaigns, events, or closing periods without over-provisioning. Retail and fintech companies increased their capacity by 70% during key periods without raising fixed costs.
Modernizing Environments to Enable AI and APIs
We transform legacy systems to support data flows, ML, and new integrations. Recently, we delivered an AI- and API-ready core in under 6 months for an insurance company, reducing technical debt by 40%.
Recent Pilots and Exploring
From our Center of Excellence, we run pilots with internal teams and clients to test real solutions and measure their impact before scaling. These initiatives take place in real-world environments, alongside leading clients in the financial and retail sectors. References are available under NDA.
Hybrid Migration with Zero Downtime
We validated a hybrid/multicloud approach using Anthos to keep critical services running while migrating workloads to the cloud.
AI-Driven Observability for Legacy Systems
We deployed AI-powered dashboards to detect bottlenecks and anomalies in monolithic platforms, enabling prioritized refactors based on real impact.
ERP Refactoring with Serverless and Containers
We tested decomposing key modules of a legacy ERP into microservices on AWS and GCP, reducing latency and operational costs without rewriting the entire solution.
