1. What is Replatforming?
In the realm of digital transformation, replatforming stands as a balanced, strategic approach for migrating legacy applications to the cloud. Known as “lift, tinker, and shift,” replatforming involves making minor optimizations to an application during the cloud migration process — enough to take advantage of key cloud-native features but without a complete rewrite.
Unlike full-scale refactoring — where applications are entirely rebuilt to be cloud-native — replatforming retains most of the core architecture. The re-platforming approach consists of updating databases, moving to managed services, adopting containerization, or modifying certain components like authentication or APIs.
How Replatforming Compares to Other Migration Strategies
- Rehosting (Lift & Shift): This is the most basic migration path — moving your application to the cloud “as-is” without any code modifications. While rehosting is fast and inexpensive, it may not be the best approach for leveraging cloud-native advantages.
- Refactoring: This involves redesigning the entire application architecture to be fully cloud-native. It’s highly scalable and future-proof but also resource-intensive and time-consuming. Typical examples are microservices, container orchestration, and serverless functions.
- Rebuilding or Replacing: For the legacy system, businesses opt to rebuild the application from scratch or replace it entirely with a SaaS solution — an expensive but often necessary last resort.
Replatforming is the sweet spot: It optimizes performance and cost without demanding a full rewrite. For many mid-to-large-sized European businesses, especially those with partially modernized systems, it offers the best return on investment.
2. Why is Replatforming Important?
For modern enterprises, particularly in highly regulated and competitive environments like the EU, application replatforming delivers numerous operational, financial, and security benefits.
Boosting Performance
By replatforming, organizations can harness cloud-native capabilities like:
- Auto-scaling to match traffic fluctuations.
- Containerization (e.g., Docker, Kubernetes) for isolated, efficient workloads.
- Cloud storage for resilient, accessible data.
These enhancements dramatically improve application responsiveness and resilience, essential for real-time applications like eCommerce replatforming.
Cost Optimization
Traditional infrastructure often leads to over-provisioning or under-utilization. Replatforming services help reduce waste by introducing:
- Pay-as-you-go pricing models
- Rightsizing compute and storage
- Using managed services (like AWS RDS or Azure Cosmos DB)
All of these directly contribute to lower operational expenditures (OpEx) and improved financial transparency.
Enhanced Security & Compliance
Compliance with GDPR, HIPAA, or ISO 27001 isn’t optional — it’s a must. Through replatforming, businesses can implement:
- Cloud-native identity and access management (IAM)
- Network segmentation and encryption
- Automated compliance monitoring tools
European enterprises, especially in sectors like fintech, healthcare, and logistics, benefit immensely from these improved controls.
DevOps & CI/CD Integration
One of the major incentives for application replatforming is to integrate with modern development pipelines:
- Continuous Integration/Continuous Deployment (CI/CD)
- Infrastructure as Code (IaC) via tools like Terraform or Ansible
- Monitoring and feedback loops using Prometheus, Grafana, or AWS CloudWatch
This integration streamlines development cycles and enables faster, more reliable feature releases.
Leveraging AI & Data Analytics
Replatforming provides predictive insights and customer behavior analysis, enabling your business to make informed decisions and better integrate big data analytics tools, machine learning pipelines, or ETL workflows.
3. When Should Businesses Consider Replatforming?
Running on Outdated On-Premises Infrastructure
Legacy systems were not built for today’s dynamic workloads. Slow performance, limited scalability, and inability to support cloud-native services are key warning signs.
Rising Maintenance Costs
If your IT team is spending more on patching, monitoring, and keeping lights on than on innovation, it’s time to replatform.
Poor Integration Capabilities
Modern systems need to play nicely with APIs, microservices, and AI/ML modules. Replatforming enables modular design and better interoperability.
Desire for Multi-Cloud or Hybrid Cloud Strategies
More European businesses are moving toward hybrid cloud or multi-cloud setups for flexibility, risk management, and regulatory compliance. Replatforming services from NTQ Europe can ensure your application architecture is ready for such strategies.
4. Key Steps in Replatforming
Successful replatforming approach requires technical know-how and a strategic plan aligning with your business goals. At NTQ Europe, we guide your business through each stage to gain both affordability and responsive support; without compromising on quality or compliance.
Step 1: Cloud Readiness Assessment
Before making code changes or selecting platforms, we begin with a cloud readiness assessment and analysis of your existing IT landscape to define a tailored replatforming strategy. This step ensures that your application is suitable for replatforming, and helps identify legacy components or technical debt that may become migration roadblocks.
We evaluate:
- Dependencies & architecture complexity: Hard-coded configurations, tightly coupled services, or monolithic structures,…
- Resource utilization: CPU, RAM, disk I/O, bandwidth consumption.
- Business constraints: Budget, compliance needs, timelines, and operational risks.
Step 2: Choosing the Right Architecture
Once the assessment is complete, it’s time to select the right target architecture. The “right” choice depends on your scalability demands, operational model, and compliance requirements.
Containerization (Docker, Kubernetes)
Breaking large applications into modular microservices using containers like Docker helps streamline development and scale specific services independently. Kubernetes handles orchestration, enabling high availability and zero-downtime rollouts.
Use case: Enterprises modernizing large monolithic applications into scalable workloads without refactoring everything.
Serverless Computing
Certain processes can be moved to serverless platforms like AWS Lambda or Azure Functions. This eliminates the need to manage infrastructure and allows you to pay only when the function is triggered.
Great for: Scheduled jobs, real-time event processing, or sporadically used services.
Managed Cloud Services
By migrating databases and other core components to managed services (e.g., AWS RDS, Azure Cosmos DB, Google Cloud Run), companies reduce maintenance overhead and improve reliability.
Step 3: Migration & Testing
Replatforming often requires minor modifications to your application stack to ensure your application is optimized, stable, and secure before going live.
- Refactoring selective components: Updating the database schema, rewriting API endpoints, or integrating OAuth-based authentication systems.
- Data migration: Ensuring integrity and performance in the new cloud environment.
- Testing: Conducting performance, compatibility, and security tests before final deployment.
Step 4: CI/CD Integration & Performance Monitoring
To maximize the benefits of replatforming, automation must be part of the picture. This is where CI/CD pipelines and performance observability tools come into play.
CI/CD Pipeline Automation
Using tools like:
- Terraform or Ansible for infrastructure provisioning
- Jenkins, GitHub Actions, or GitLab CI for automated deployment
- GitOps for version-controlled infrastructure migration
You can release faster, more reliably, and with greater confidence.
Performance Monitoring
Post-migration, it’s critical to track how your applications are performing in real time. We typically implement tools like AWS CloudWatch, Prometheus and Grafana to ensure consistent uptime, rapid issue resolution, and optimization insights.
5. Challenges in Replatforming & Proven Solutions
Like any transformation journey, replatforming comes with its set of hurdles. However, with the right approach and tools, these can be managed — or avoided altogether.
Legacy Application Incompatibility
- Problem: Older applications might use outdated libraries or architectures not compatible with the target cloud environment.
- Solution: Instead of a full rewrite, we take a gradual approach — refactoring only the components that hinder migration while wrapping others in containers or APIs.
Risk of Downtime
- Problem: Migrating core services can result in outages that disrupt business operations.
- Solution: We deploy zero-downtime migration strategies using blue-green or canary deployments and thorough pre-launch testing.
Uncontrolled Cloud Spending
- Problem: Without oversight, costs can escalate rapidly in the cloud — especially when autoscaling or multiple environments are involved.
- Solution: Our teams implement FinOps practices — tagging, budgeting, real-time usage tracking — and leverage built-in tools like AWS Cost Explorer or Azure Cost Management.
Security and Compliance Gaps
- Problem: Moving to the cloud without security guardrails can result in data breaches or non-compliance.
- Solution: We integrate:
- IAM policies for fine-grained access control
- Network segmentation and data encryption
- Automated compliance checks for standards like GDPR or ISO 27001
This ensures that replatforming services from NTQ Europe not only boost agility but also improve your overall security posture.
