AWS Modernization Expert

Transform Legacy Applications into Cloud-Native Solutions

Expert modernization consulting to migrate .NET and Node.js applications to AWS with serverless, containers, and modern architecture patterns

Led by AWS-Certified Solutions Architect, DevOps Engineer, and Security Specialty Professional

Why Modernize

Legacy applications are expensive to maintain, slow to change, and difficult to scale. Every day you delay modernization, you're accumulating technical debt and missing opportunities to deliver value faster. Your competitors are moving to cloud-native architectures that enable rapid innovation and dramatic cost savings.

Modern cloud-native applications leverage serverless computing, containers, and managed services to eliminate infrastructure overhead, scale automatically, and reduce operational costs by 40-70%. With the right modernization strategy, you can transform monolithic applications into flexible, maintainable microservices that your team can deploy independently.

Whether you're running legacy .NET Framework applications on Windows servers, Node.js apps on aging infrastructure, or monoliths that are too risky to change, a phased modernization approach can transform your application portfolio without a risky "big bang" rewrite.

Typical Outcomes

  • 40-70% cost reduction — by eliminating servers and leveraging serverless/containers
  • 10x faster feature delivery — with microservices and independent deployments
  • Automatic scaling — from zero to thousands of requests without manual intervention
  • Improved reliability — with managed services and built-in redundancy
  • Reduced technical debt — with modern patterns and maintainable code

What's Included

A comprehensive approach to modernizing your applications with minimal risk and maximum value

Assessment

Identify modernization priorities and build a data-driven roadmap

Comprehensive analysis of your application portfolio to identify modernization opportunities and create a prioritized roadmap

  • Application inventory and dependency mapping
  • Technical debt analysis and risk assessment
  • Cost-benefit analysis for each modernization candidate
  • Prioritized roadmap with effort estimates and expected ROI

Architecture Patterns

Design serverless, containerized, and event-driven systems tailored to your goals

Modern cloud-native architecture design tailored to your application's needs and constraints

  • Serverless architecture with Lambda, API Gateway, and managed services
  • Container-based architecture with ECS or EKS
  • Microservices decomposition strategies
  • Event-driven architecture with EventBridge, SQS, and SNS

Delivery Foundations

Establish automated pipelines and infrastructure as code for consistent deployments

CI/CD pipelines and infrastructure as code to enable safe, automated deployments of modernized applications

  • Automated build and deployment pipelines
  • Infrastructure as code with CDK or CloudFormation
  • Automated testing and quality gates
  • Blue/green or canary deployment strategies

Incremental Execution

Modernize safely with phased migrations and rollback protection

Phased migration approach that delivers value incrementally while minimizing risk and disruption

  • Strangler fig pattern for gradual migration
  • Feature-by-feature or service-by-service migration
  • Parallel run strategies to validate behavior
  • Rollback plans and risk mitigation

Knowledge Transfer

Enable your team to maintain and extend modernized systems independently

Comprehensive documentation and training to ensure your team can maintain and extend the modernized applications

  • Architecture documentation and decision records
  • Code walkthroughs and pair programming sessions
  • Operational runbooks and troubleshooting guides
  • Best practices for ongoing modernization

Example Engagement

Example Engagement: Healthcare SaaS Migrates .NET Monolith to Serverless, Cuts Costs 65%

Scenario modeled on typical .NET modernization projects adopting AWS serverless architectures.

The Challenge:

A .NET Framework monolith on Windows servers causes high costs and slow release cycles.

The Solution:

Apply a phased modernization using the strangler-fig pattern; migrate to Lambda, API Gateway, and DynamoDB; implement CI/CD with GitHub Actions and CDK.

The Results:

  • ~65% cost reduction from server elimination and auto-scaling
  • 10× faster deployments through microservices
  • Zero-downtime migration with parallel runs
  • Improved developer velocity via independent service deployment

Clients can expect transparent communication, measurable milestones, and architecture decisions grounded in AWS best practices.
