Application Modernization: A Roadmap for Success

Defined as the process of updating existing software for newer computing approaches, application modernization breathes new life into outdated systems. Without it, businesses risk inefficiency, security vulnerabilities, and obsolescence. The benefits are extensive, ranging from improved agility to better customer experiences and reduced operational costs.

This guide explores what application modernization involves, the strategic processes to approach it, and how to overcome common obstacles. Let’s map the path to future-proof your organization’s technology stack.

Understanding Application Modernization

Application modernization involves overhauling legacy software and systems to better align with current business needs and technological capabilities. This typically means updating or replacing outdated technologies, operating systems, or software applications that are costly to maintain and hinder innovation. The ultimate goal is not merely to update the technology stack but to improve overall business effectiveness, enabling organizations to meet and exceed their strategic objectives.

The cornerstone of application modernization is the transformation roadmap. This strategic plan outlines critical elements such as timelines, required resources, potential risks, and corresponding mitigation strategies. It serves as a guide for the process, ensuring that each step is calculated and aligned with the end goal.

When prioritizing which applications to modernize, it’s practical to focus on high-value applications first. These are the ones that, when improved, can greatly impact business operations and offer a better return on investment. Organizations are increasingly adopting Agile methodologies in these projects. Agile application modernization emphasizes iterative progress, adaptability, and cross-functional collaboration, ensuring that teams can effectively manage the challenges that arise during a modernization initiative.

What is application modernization?

Application modernization refers to refurbishing legacy software to embrace new computing approaches, thereby extending the application’s value. It involves leveraging modern cloud environments, mobile platforms, and other new technologies to revitalize older systems. While legacy systems might still serve their original purpose, they often fall short when it comes to newer operational demands such as scalability, integration, and user experience. This disconnect makes modernization not only a strategic move to future-proof organizations but also necessary for maintaining competitive edge and operational agility.

Application modernization isn’t a one-size-fits-all process; it may involve various strategies such as re-hosting, re-platforming, re-architecting, or even re-coding. Each approach is selected based on the application’s requirements, desired outcomes, and the organization’s overall digital transformation goals.

Why is application modernization important?

In a tech-driven marketplace, staying current is crucial. Legacy applications often exist as monolithic structures that conflict with modern, dynamic business requirements. Modernization is vital for businesses that need to update or scale these systems, align them with current practices, or break them down into more manageable pieces.

Improved performance, reduced risk, and cloud scalability are among the tangible benefits of application modernization. It enables companies to tap into the potential of modern software platforms, tools, and frameworks, thus improving operational efficiency without starting from scratch. By moving to multi-cloud or hybrid cloud environments, businesses can optimize their flexibility and cost-effectiveness, maximizing their IT investments.

The drive to modernize software systems is rooted in tangible business benefits:

• ‍Improved Operational Efficiency: Streamlining processes, minimizing redundancies, and automating tasks result in increased productivity and better resource deployment.‍
• Enhanced Security: Modernized applications come equipped with the latest security features to safeguard sensitive data and reduce the risk of breaches and cyber threats.‍
• Increased Flexibility and Scalability: The agility provided by modernized applications allows companies to quickly adapt to market changes, scaling resources up or down as needed.‍
• Cost Savings: By replacing legacy systems with modern solutions, organizations can reduce operational costs while enhancing functionality and service quality.‍
• Better Customer Experience: Offering a faster, more reliable, and user-centric experience leads to increased customer satisfaction and loyalty.
  

According to Statista, the global application modernization services market is projected to reach $25.5 billion by 2025, highlighting the growing importance of modernization efforts.

The Process of Application Modernization

Application modernization involves a multi-step process with a systematic approach to updating and refining legacy systems. This process encompasses assessing existing applications, setting clear modernization goals, identifying critical legacy applications, and laying out a detailed roadmap. It also includes the careful selection of modernization strategies, their application, and thorough validation before deploying updated applications into a live environment.

1. Assessing the Current Application Portfolio

The first step in successful application modernization is a comprehensive assessment of the current applications. Organizations must audit their entire application portfolio to identify which systems require modernization by evaluating their business value, technical condition, and alignment with current and future company goals.

Real-World Example: A financial services company discovered that their legacy customer management system was causing frequent downtime and hindering customer service. By auditing their applications, they identified this system as a priority for modernization.

Tools like LeanIX or CAST Highlight provide valuable insights during this phase by offering a clear view of the application inventory. The assessment helps prioritize applications for modernization efforts, focusing on those with high business value and technical needs.

2. Defining Modernization Goals and Objectives

To define a successful application modernization strategy, organizations must establish clear business, operational, and technical goals. These objectives guide the modernization efforts, dictating the extent and approach required for code changes.

Ask Yourself:

• What are the business drivers for modernization?
• What outcomes do we expect from modernizing this application?
• How will modernization align with our long-term digital transformation goals?
  

Factors such as interconnectedness, return on investment, and drivers for change should be considered to estimate the effort required. The strategic goals set during this phase serve as benchmarks to measure the success of modernized applications post-implementation.

3. Identifying Legacy Applications in Need of Modernization

Legacy applications are often characterized by their cumbersome nature, difficulty to update, and complexity in troubleshooting. Identifying these applications is crucial, as they are prime candidates for modernization.

High-Value Applications:

• ‍Core Business Functions: Applications critical to daily operations.‍
• Customer-Facing Systems: Apps that directly impact customer experience.‍
• High Maintenance Costs: Systems that are expensive to maintain due to outdated technology.
  

Evaluating the potential return on investment and understanding the specific risks and challenges associated with modernizing each application play crucial roles in this identification process.

4. Creating an Application Modernization Roadmap

Developing an application modernization roadmap is a strategic process that involves defining the approach for transforming high-value applications to greatly enhance business operations. This includes outlining the potential ROI and the improvements expected in various business areas.

Key Components of a Roadmap:

• ‍Timeline and Milestones: Setting realistic deadlines.‍
• Resource Allocation: Determining the budget and personnel needed.‍
• Risk Management Plan: Identifying potential risks and mitigation strategies.‍
