Maximize value in your application modernization plan

Migrating to the cloud, modernizing applications and data, and infusing AI into your apps are more than technological upgrades. They’re strategic initiatives that drive significant financial and business impact. In the App Modernization Guidance for Azure, the first step in planning is making a business case that quantifies the impact on your organization and the value that platform as a service (PaaS) brings.

The second part is planning the technical strategy to use for the applications you have targeted for modernization. This guide follows the 6 Rs of rationalization—Rehost, Replatform, Refactor, Rebuild, Retire, and Retain.

The following sections help you make the case, secure funding, and determine profitability for the modernization strategy you choose.

What to include in your plan

A comprehensive business plan includes the following:

• Problem statement. Clearly define any issues with your current applications and the benefits of modernization.
• Cost-benefit analysis. Provide a detailed analysis of the costs involved in modernization versus the expected benefits, including increased revenue and reduced maintenance costs.
• Phased implementation plan. Propose a phased approach to modernization to manage risks and ensure continuous business operations.
• Regular reviews. Make sure you continuously monitor key metrics to assess the impact of your modernization efforts and adjust as you go.
• Stakeholder engagement. Keep stakeholders informed and involved in the modernization process to ensure alignment with business goals.

Plan to maximize ROI

Strategic planning and prioritization are crucial for maximizing your return on investment (ROI). By developing a comprehensive business case, you can clearly define the problem you want to solve, outline the benefits of application modernization, and provide a detailed cost-benefit analysis. Prioritizing high-value applications and balancing short-term wins with long-term goals help you maintain momentum and achieve long-term objectives.

Reduce costs

Migrating applications to PaaS and modernizing them can lead to substantial cost savings. Traditional on-premises infrastructures often require high capital expenditures (CapEx) for hardware and maintenance. By moving to cloud platforms and services, you can shift to an operational expenditure (OpEx) model, paying only for the resources you use. This pay-as-you-go approach reduces upfront costs and allows for better budget management.

For example, application modernization can help you optimize resource use and reduce operational costs. You can take advantage of cloud-native features such as autoscaling, dynamic storage, and advanced networking. These efficiencies translate into a higher ROI as your organization can allocate resources more effectively and shift its focus to strategic initiatives.

According to a recent analysis, Azure can help you improve time-to-market, increase developer efficiency of up to 25%, and reduce application downtime by up to 25%. These tangible business benefits can help you remain competitive, capture incremental revenue, minimize revenue loss and fines from downtime, plus increase engagement and retention of key talent.

Another recent report shows that migrating to Azure and modernizing applications can provide substantial revenue gains on an annual basis and systematically improved organizational resilience.

Enhance agility and scalability

Modernized applications are inherently more agile than traditional architectures, enabling you to respond quickly to market changes and customer needs. You can scale resources up or down based on demand, providing optimal performance during peak times without over provisioning during off-peak periods.

Additionally, you can update and deploy modern applications more rapidly, reducing time-to-market for new features and services. This agility enables you to stay competitive and innovate continuously.

Improve security and compliance

Cloud providers invest heavily in security measures and compliance certifications, offering a level of protection that is often difficult for individual businesses to achieve on their own. By migrating to the cloud and modernizing your applications, you benefit from these robust security frameworks.

Set a realistic timeline

A well-structured timeline, focusing on short-term, medium-term, and long-term goals, ensures a smooth transition to full modernization, ultimately leading to significant profitability within 24 to 36 months.

• Short-term (0 to 6 months). Focus on quick wins and high-impact applications to demonstrate early success and build momentum.
• Medium-term (6 to 18 months). Continue with phased implementation, targeting more complex applications and integrating advanced technologies.
• Long-term (18 to 36 months). Achieve full modernization, realizing significant cost savings and revenue growth.

Break-even analysis and path to profitability

A strategic business plan helps set financial expectations. We recommend including the following data:

• Initial investment. Calculate the total costs of modernization, including development, infrastructure, and training expenses.
• Cost savings. Identify areas where modernization helps reduce costs, such as lower maintenance expenses and improved operational efficiency.
• Revenue growth. Estimate the potential increase in revenue from enhanced user experience and new features.
• Break-even point. Expect to break even within 18 to 24 months, depending on the scope and scale of your modernization efforts.
• Profitability. Expect to realize a profit within 24 to 36 months as the benefits of modernization fully materialize and your organizational operations get more efficient.

Create an estimation framework to secure funds

To secure funds for migration and modernization projects, you need a robust planning and estimation framework. Your plan must:

• Identify objectives. Clearly define the goals and expected outcomes of the project.
• Assess risks. Identify potential risks and develop mitigation strategies so you can forecast costs accurately.
• Engage stakeholders. Engage stakeholders early and communicate the benefits and ROI of the project.
• Get funding. Develop a comprehensive funding strategy that includes capital and operational expenditures.

Budget and forecast to optimize funds

Effective budgeting and forecasting are crucial for optimizing funds. We recommend using the FinOps framework for financial accountability in cloud operations. To manage costs, FinOps uses financial modeling for:

• Predictive analytics. To estimate costs associated with various modernization scenarios, use the historical data from the assessment of your current digital estate and future-looking projections.
• Scenario planning. Clarify the financial implications associated with the various modernization scenarios.
• Cost optimization. Look for ways to lower cloud-based OpEx—for example, by rightsizing resource and service allocations and capitalizing on the discounts associated with committing to the use of term-based allocations.

FinOps practices help you to track the business value of your application modernization efforts using:

• Key performance indicators (KPIs) that measure cost savings, performance improvements, increased revenue, and other metrics.
• Continuous monitoring that tracks actual expenditures against projections to reveal areas for improvement on an ongoing basis.
• Benchmarking to compare performance against best practices, industry standards, or other independent sources that help you identify opportunities for optimization.

Determine profitability using unit economics

Unit economics is a critical analytical method that measures the direct financial gains and losses from a specific unit of your business, such as a customer, transaction, or product. For application modernization projects, you need to evaluate the costs and revenues associated with modernizing each application or user interaction.

To start, we recommend using the following metrics:

• Performance metrics help you track application performance improvements, such as reduced latency, increased uptime, and faster response times.
• Cost metrics help you monitor savings from reduced infrastructure expenses, lower maintenance costs, and optimized resource usage.
• User experience metrics help you assess user satisfaction through surveys, a net promoter score (NPS), and user feedback.
• Operational metrics help reveal improvements in IT operations, such as reduced incident response times and increased automation.

In addition, we recommend monitoring the following behavioral changes:

• Adoption rates. Track how quickly and effectively teams are adopting new tools and processes. High adoption rates indicate successful change management.
• Productivity gains. Measure increases in productivity, such as faster development cycles, reduced time-to-market, and more efficient workflows.
• Collaboration improvements. Evaluate any enhancements in team collaboration and communication that follow from the use of modernized platforms and tools.

Determine profitability using benchmarking

Effective FinOps benchmarking for profitability gives you insight into your cloud expenditures, helps you optimize resource usage, and shows you how to improve financial performance. Regularly assessing and adjusting strategies based on benchmarking results fosters a culture of financial accountability and operational efficiency.

For example, to assess cost allocation, you can:

• Analyze how costs are attributed to different teams, projects, or business units.
• Ensure that chargeback or showback mechanisms are in place for accountability.

To measure usage, you can:

• Monitor cloud resource usage patterns to identify trends and anomalies.
• Evaluate the utilization rates of resources to optimize spending.

To show profitability, you can:

• Establish KPIs such as cost per transaction, cost of goods sold (COGS), and ROI.
• Forecast using historical data to predict future costs and resource needs, enabling better budget management.

In addition, a best practice is to regularly review financial performance and resource allocation to ensure they align with your business goals.

Use a phased implementation

To minimize disruption and manage risks, it’s best to implement your modernization strategy in manageable phases. We recommend using T-shirt sizing, a repeatable approach to project management that assigns a size (small, medium, large, or extra-large) to the work involved. This straightforward approach simplifies decision-making and helps you meet governance requirements, manage risks, and allocate resources.

To use T-shirt sizing for application modernization, try the following:

1. Identify application components. Decompose your application into manageable components—for example, modules, features, and subsystems.
2. Assess complexity. On a per-component basis, assess complexity according to functionality, dependencies, data volume, risk, and other factors.
3. Assign T-shirt sizes. Categorize each component into a T-shirt size according to its complexity. For example, relatively simple components with minimal dependencies and risks are a small size, whereas very complex components that require extensive modernization are the extra-large size.
4. Prioritize components. Give a priority to each component of your modernization effort based on its business value, risk, dependencies, and other factors.
5. Create a phased-implementation plan. To best manage risks and disruptions throughout the modernization process, group components according to size into phases that achieve the desired balanced mix of complexity and business value.
6. Schedule the phases. Establish a clear timeline with milestones to track progress and ensure timely delivery.

Set up a Center of Excellence

For this type of phased implementation, we recommend establishing a Center of Excellence—that is, a centralized team to provide leadership and expertise. A Center of Excellence can help improve the efficiency of your modernization efforts while helping to reduce risk, improve quality, and decrease the time to market.

Its role is to:

• Centralize expertise, serving as a repository of knowledge and offering consultative guidance.
• Standardize processes and evaluate tools, developing modernization templates for assessment, planning, execution, and other key tasks.
• Ensure compliance and manage risk, enforcing policies for security, standards, and governance regulations.
• Train and develop application modernization teams, helping to enhance skills, facilitate knowledge transfer, and align organizational culture with a mindset of continuous learning.

A Center of Excellent helps support phased implementations at every step, from assessing components and assigning T-shirt sizes to planning to sharing best practices.
