**Re-hosting**: Moving applications to modern infrastructure without + altering functionality. + - **Re-platforming**: Making minimal changes to optimize applications for a + new platform. + - **Refactoring**: Rewriting parts of the code for better structure without + changing external behavior. + - **Re-architecting**: Rebuilding significant portions of the application to + improve scalability and flexibility. + - **Rebuilding**: Writing the application from scratch using modern + architectures and technologies. + - **Replacement**: Switching to a completely different solution or commercial + off-the-shelf software. + +3. **Design and Prototyping** + - **Design Architecture**: Create a modern architecture that fits the new + objectives (e.g., microservices, cloud-native). + - **Technology Selection**: Choose new technologies, tools, and platforms + that align with modern standards and business requirements. + - **Prototyping**: Develop a proof of concept to validate assumptions and + design choices. + +4. **Implementation** + - **Code Conversion**: Migrate code to new languages, frameworks, or + platforms as needed. + - **Componentization**: Break down monolithic applications into smaller, + manageable services or components. + - **Integration**: Ensure new components communicate effectively with + existing systems and third-party services. + - **Testing**: Perform extensive testing (unit, integration, system, and user + acceptance testing) to ensure quality and reliability. + +5. **Deployment** + - **Infrastructure as Code (IaC)**: Use IaC tools for consistent and + repeatable environment setups. + - **Continuous Integration/Continuous Deployment (CI/CD)**: Implement CI/CD + pipelines for seamless deployments and faster iterations. + -
