Accelerating Application Modernization

Practical Guide

We all face tough questions from stakeholders when making big changes to our software applications:

  • Why is it taking so long?
  • Do we really need a 20-person team on this?
  • Why is the changed system misbehaving?

This guide details how key activities of application modernization – from ‘simple’ framework or database swap to refactoring and breaking monoliths to microservices, can be dramatically sped up by using software intelligence.

Learn about:
  • The five approaches to application modernization and transformation.
  • The most common Analysis and Action modernization motions.
  • Accelerating the common motions by leveraging software intelligence.

This guide is the result of distilling the experience of helping businesses, governments, consultancies, and integrators modernize complex, custom-built software applications.
