Overview
What Is Application Modernization, Monitoring and Observability?
Updating application architecture and deployment, with monitoring that shows how applications behave in real use.
The Need
- Legacy applications that are hard to change
- Performance problems that are hard to diagnose
- Applications that cannot use modern cloud services
The Approach
- Assess applications and choose a modernization path
- Update architecture and deployment
- Add tracing, metrics and alerting
Assumptions and Dependencies
- Access to application code and documentation
- Application owners and teams
- Agreed performance and availability targets
