Cloud Modernization and Scalable Architecture
We drive the transition from legacy systems to cloud-native architectures, enabling greater speed, stability, and scalability.
At Crombie, we guide you through cloud modernization and scalable architecture so you can operate with greater agility, security, and efficiency. We apply cloud-native practices, progressive refactoring, and architectural redesign to boost performance, lower operational costs, and increase availability.

The Challenges We Tackle at Crombie
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
At Crombie, 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.
Cloud Modernization and Scalable Architecture 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%.
AI Solutions ans Recent Pilots
From our Center of Excellence, we run pilots with internal teams and clients to test AI 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.

All worksEmpower Your Business with Cloud Modernization and Cloud-Native Architecture
Let’s create your roadmap to migrate, optimize, and future-proof your stack.
At Crombie, we design a progressive modernization process that avoids downtime and keeps operations stable at all times. We work with parallel environments, controlled deployments, and component-based refactoring to minimize risk. This approach allows your platform to evolve without impacting users or critical processes.
We conduct a technical and functional assessment to identify critical modules, technical debt, dependencies, and operational costs. Based on that, we define which areas need refactoring, which components can be migrated as-is, and which parts require redesign. This ensures an efficient, realistic, and low-risk roadmap.
Yes, the architecture we design is based on cloud-native principles to ensure scalability, resilience, and efficient resource usage. We structure systems using containers, microservices, managed cloud services, and automation practices that support rapid iteration and high availability. This approach enables platforms to scale smoothly as your business grows.
A cloud-native architecture is an approach to building systems that run directly in the cloud using scalable, distributed components. It leverages containers, microservices, automation, and managed cloud services to deliver high performance, fast deployments, and built-in resilience. This model allows platforms to evolve quickly and handle demand without disruption.
