Application Rationalization: Your Guide to Modernizing Legacy Systems

Imagine a world where those certain legacy systems don’t hold your business back. A world where modernization isn’t a daunting task, but a springboard for innovation.

In comes Application Realization, a crucial process towards managing and improving your legacy systems to increase your scalability. Legacy systems can become anchors, hindering flexibility and scalability.

Let’s start by understanding what Application Realization is

Application rationalization is the process of organizing and streamlining your software application portfolio to best support your business goals. It is critical for maintaining the overall hygiene of your portfolio irrespective of where you are running your applications. Overall, you can define it as the effort to strategically identify business applications across an organization to determine which should be kept, replaced, retired, or consolidated.

By taking a rationalized approach, you avoid the pitfall of migrating everything or relying on outdated applications. This saves time, resources, and ensures a more efficient and manageable application environment.

A Blueprint for Application Realization

Every approach needs a plan to follow, and what better way to do it than this six-step process.

  1. Assessment: Analyze each application’s functionality, security posture, and integration needs.
  2. Rationalization: Categorize applications as retain, refactor, re-platform, or retire based on the assessment.
  3. Planning: Develop a detailed migration plan for each application, considering costs, timelines, and dependencies.
  4. Modernization: Implement the chosen strategy by leveraging cloud technologies and best practices.
  5. Testing and Validation: Meticulously test the migrated applications to ensure seamless functionality.
  6. Monitoring and Optimization: Continuously monitor performance and identify opportunities for further improvement.


Legacy Migration: A Separate but connected project

While closely linked, application rationalization lays the groundwork for a successful legacy migration, which involves:

  • In-depth Analysis: Assess the technical feasibility and cost implications of migrating legacy systems.
  • Data Backup and Preparation: Ensure secure data transfer and establish a robust cloud architecture.
  • Execution and Monitoring: Carefully migrate system components, followed by rigorous testing and performance optimization.

Assessing ROI: Quantifying the value

It’s crucial to measure the benefits of your migration efforts. Consider factors like reduced maintenance costs, improved scalability, and enhanced flexibility. Google Cloud’s Cloud Acceleration Migration Program (CAMP) offers valuable data-driven insights to support your ROI calculations.

Continuous Improvement: The cycle never ends

Application rationalization is an ongoing process. Regularly evaluate your IT landscape, identify new opportunities for modernization, and adapt your strategies based on evolving business needs.
