Modernising .NET Applications on AWS: A Path to Innovation and Efficiency

Are your legacy .NET applications holding back your business agility?

Many organisations run critical .NET applications built for on-premises environments. However, these monolithic applications often struggle with scalability, performance, and maintenance complexities in today’s fast-paced digital landscape. AWS provides robust tools and services to modernise your .NET workloads, transforming them into agile, cloud-optimised solutions.

Why Modernise .NET Applications on AWS?

Modernising .NET workloads is about enabling faster innovation, improved performance, and enhanced reliability. AWS offers comprehensive services and frameworks that make migrating and modernising .NET applications seamless. Learn about Modernising .NET Applications with AWS.

Key Approaches to .NET Modernisation on AWS

  • Rehosting (“Lift and Shift”): Quickly migrate .NET applications to Amazon EC2 Windows instances with minimal changes.
  • Replatforming: Move .NET apps to managed services like AWS Elastic Beanstalk or Amazon ECS with Windows containers.
  • Refactoring to .NET Core: Transform applications into microservices using .NET 6 on AWS Lambda or AWS App Runner.
  • Database Modernisation: Migrate from legacy SQL Server to Amazon RDS or Amazon Aurora for scalable, managed database services.

Explore the official AWS .NET Modernization Guide for detailed strategies.

Benefits of Modernising .NET on AWS

  • Enhanced Scalability: Scale applications automatically to handle varying workloads.
  • Reduced Operational Overhead: Shift to fully managed services, reducing infrastructure management.
  • Improved Developer Productivity: Leverage DevOps tools, CI/CD pipelines, and Infrastructure as Code.
  • Increased Application Resilience: Design fault-tolerant architectures using AWS’s global infrastructure.
  • Better Cost Optimisation: Pay only for resources you use, optimise licensing with AWS License Manager.
