How to Create App Modernization Roadmap

With the speed at which technology is developing, businesses must update their applications to stay competitive and fulfill customer requirements.

This is where application modernization becomes relevant. The practice of modifying and updating old platforms and applications to match the shifting requirements of businesses in the current digital era is known as “application modernization.”

This blog will take you through the development process of the application modernization roadmap.

What is the Application Modernization Roadmap?

A well-organized project strategy for updating an outdated application to newer technology is called an app modernization roadmap.

It is a crucial step for businesses aiming to maintain their competitive edge in today’s market while future-proofing their IT network.

Why does the Business need Application Modernization?

The best and only way to deal with old applications that limit corporate growth and create more issues than they solve is through application modernization services.

In addition to saving money on administration expenses for the use of outdated technology, these modernization initiatives enable companies to take advantage of more advanced features like web services and interfaces.

  • Scalability and agility requirements are major drivers of application modernization:

Business changes and requirements can be challenging to adjust to, as legacy systems frequently have scalability and adaptability limits. Businesses can take advantage of emerging innovations and frameworks that provide more scalability and agility by updating their applications.

  • Security is yet another crucial component:

Because of out-of-date security mechanisms, legacy applications are more susceptible to cyberattacks. Companies can put robust safety precautions in place to protect confidential information and reduce risks by modernizing their apps.

  • Another important factor driving application modernization is cost-effectiveness:

Maintaining legacy systems can be expensive and requires regular manual adjustments. Companies can increase overall productivity, automate work, streamline procedures, and reduce operating expenses by updating the applications.

Also, any business can control its working process, set attainable goals, and maintain flexibility in case adjustments are needed along the way with the use of an application modernization roadmap.

How does Application Modernization help your Business?

An application modernization roadmap provides a guiding structure that enables organizations to navigate the complexity of modernization, bring about digital change, and attain long-term business success.

Strategic Alignment:

It guarantees that the modernization effort stays close to the overall strategic direction of the business enterprise. It enables them to focus on other values in their businesses.

Clear Direction:

It is a strategy in the implementation phase that outlines the roadmap and timeline for shifting from legacy systems to advanced architectures and technologies.

Updating apps with clear direction is the guiding light for the modernization path.

Risk Management:

It allows for the identification of prerequisites and risks, which makes it possible to plan for mitigation actions. It reduces the adverse effects that may arise from the process of modernization.

Resource Planning:

Whether it’s allocation of budget, operational or development time, or personnel development, this strengthens the management of modernization processes and helps to end up with successful implementation.

Stakeholder Communication:

It enables stakeholders, including business leaders, the IT/CRT team, and end users, to gain insights that make communication and alignment among them easier.

It can be done by introducing transparency and articulating the roadmap along with the objectives

Measurable Progress:

It indicates specific phases and performance indicators, which enable organizations to monitor and evaluate if their modernization initiatives are effective. It helps to rationalize strategies to reach their objectives whenever needed.

Essential elements of a successful Application Modernization Roadmap

Here are the elements and practices to be considered and followed while developing an application modernization roadmap:

Project Schedule:

A well-defined schedule aids in establishing reasonable plans and motivates teams to guarantee that each of their project schedules and financial plans match the broader modernization objectives.

Current State Assessment:

Carry out an in-depth study of the current application framework containing legacy systems, architecture, technologies, connections, and business processes.

This assessment results in pinpointing pain areas, technical debt, and the chance of modernization.

Business Objective Alignment:

Coordinate modernization activities with the primary purpose or strategic objectives of the business and the organization. Identify the primary goals of modernization and start aligning accordingly.

The goals can be cost reduction, agility improvement, enhanced user experience, or regulatory compliance to tackle modernization issues.

Technology Stack Evaluation:

Assess current tech stacks to pinpoint technologies or platforms that have become obsolete, against the current requirements related to agility, scalability, and security.

Discuss modern tech stacks, frameworks, and platforms that are in line with business objectives and provide long-term feasibility and scalability.

Cloud Adoption Strategy:

Evaluate the pros as well as cons of virtual applications without the need for local physical servers and computers.

Put together a cloud adoption strategy that looks into aspects such as workload suitability, cloud service types (IaaS, PaaS & SaaS), cloud providers, data storage location, security, and compliance issues.

Microservices Architecture:

Introduce a microservices-based architecture instead of a monolithic one for further improvement of agility, extendibility, and maintainability.

Break down the existing application into microservice components, and specify a plan for remaking or refactoring them as individual microservices in the application.

DevOps Implementation:

Adopt the DevOps approach that facilitates the use of automation to develop, test, deploy, and operate software.

Adopt CI/CD pipelines, IaC, and automated testing throughout the modernization to quicken it up and make developers and operations teams work together smoothly.

Data Modernization:

Determine the data storage, processing, and analytics capabilities that are within the present applications.

Formulate a data modernization plan that covers the execution of tasks such as the implementation of modern databases or data warehouses, data streams, and data governance and security.

Security and Compliance:

Consider security and compliance as key factors in and throughout the modernization process.

By applying security excellence, like identity and access management (IAM), encryption, threat detection, and risk alignment, modernized applications and data would be shielded from cyber threats and regulatory risks.

Change Management and Training:

Foster a detailed transformation management plan that encompasses an alignment of stakeholders, communication strategies, and the adoption rate of modernized applications by users.

Equip IT personnel and users with on-the-job training as well as upskilling activities to prepare them adequately for the no-hassle transition. In this way, you can ensure the full benefits of application modernization.

Metrics and Monitoring:

Establish KPIs and metrics that will monitor the outcomes of the application modernization process.

Deploy monitoring and analytic tools to ensure non-stop tracking of the performance, availability, scalability, and user experience of modernized applications.

Step-by-step Process of Application Modernization Roadmap Development

The following are the key steps for application modernization roadmap development:

#1 Conduct a study

Conduct a readiness analysis to figure out whether updating your on-premises infrastructure to enable cloud-native solutions like microservices is enough, or if it’s necessary to move entirely to the cloud.

#2 Understand technical and business needs

Determine and list your technical and business requirements. Since the business objectives are the foundation of any change, you must include a detailed description of the company’s needs in the initial sections of the modernization roadmap document.

#3 Prioritization of Initiatives

Prioritizing modernization projects based on business impact, technical complexity, and feasibility is of utmost importance.

Outline a step-by-step plan with concrete goals and deadlines for each of the initiatives to facilitate gradual accomplishment and maintain the sequence.

#4 Stakeholder Engagement

Engage and interact with a variety of stakeholders from different departments inside the organization, which includes business leaders, IT teams, operations, and end-users. Get feedback and input from stakeholders to meet business goals and user needs.

#5 Examine your existing requirements and infrastructure

Check your current application state and requirements for modernization. It is crucial to get input on the software used by various departments and discuss these concerns with all relevant parties.

Seek advice from assistance teams and investigate Voice of the Customer (VoC) suggestions when it comes to IT infrastructure that interacts with users.

#6 Develop monitoring tools

It involves establishing evaluation standards that are in line with the initiative’s objectives, putting in place mechanisms for ongoing monitoring, and establishing explicit performance measures.

#7 Risk Assessment and Mitigation

Clearly state the issue for which you’re trying to modernize the app as well as the steps in the process that are impeding your business. Examine an application inventory to determine which applications are essential and who owns them.

Define the possible bugs and problems for the modernization process that may arise, like data migration, system failure due to downtime, security breaches, and compatibility complications.

Create mitigation strategies and contingency plans aimed at addressing possible risks and securing a seamless transition process.

#8 Opt for an application modernization company

To translate your requirements and objectives into a technological architecture, engage with application modernization consulting to determine the framework that will be deployed throughout the project.

Select the approaches that work for each section of your application. Next, ascertain whether moving to an on-premises or cloud-based infrastructure is required.

#9 Design application modernization plan

Reviewing your needs, figuring out the intended result, and selecting how to utilize your resources within the constraints of time and money are all necessary when designing the perfect application modernization strategy.

Here are a few typical strategies:

1. Refactoring:

  • Evaluate the existing code to indicate which ones are unnecessary, obsolete, and ineffective.
  • Improve the current code by applying modern coding standards, design patterns, and well-architected solutions.
  • Optimize code readability, maintainability, and testability.
  • Bust larger modules into several smaller, reusable modules or services.

2. Rebuilding:

  • Find out if there are any specific components or modules that are required to be rebuilt entirely from the beginning.
  • For redevelopment, investigate the possibility of using modern development methodologies, frameworks, libraries, and application modernization tools.
  • For example, upgrade the architecture so that features that could not be implemented with the previous architecture can now be implemented.
  • Make sure that the systems have backward compatibility with old systems and data formats.

3. Replatforming:

  • Assess the current infrastructure and decide whether re-platforming is a priority or not.
  • Select a new platform or deployment model (e.g., containerization, serverless) that best matches the scalability, performance, and cost parameters.
  • Migrate the application to the chosen platform with the least amount of downtime and data loss.
  • Leverage the capabilities of the platform using the architecture of the application and build the app accordingly.

4. Encapsulation:

  • Identify shared interfaces and encapsulate them into modular and service-oriented components.
  • Include well-defined interfaces along with broader boundaries to diminish the coupling.
  • Make use of encapsulation methods like abstraction, inheritance, and polymorphism, which will hide implementation details and, therefore, increase the maintenance of your code.
  • Enforce the encapsulation and protect sensitive data using access control mechanisms.

#10 DevOps-based development

It’s critical to include developers in your plan to ensure that your modernization approach executes as intended from the outset.

Strategies for continuous improvement can facilitate an orderly, effective, and timely transfer if you choose to modernize legacy applications over a long period.

Making use of DevOps workflows will guarantee that your application modernization developers are adhering to clear procedures, allowing you to continue with your digital-first or cloud-ready roadmap.

#11 Make the implementation plan

Transforming the application modernization strategy into achievable objectives and milestones is accomplished through the creation of the implementation strategy.

It’s an in-depth plan that describes how to convert outdated programs into contemporary systems from start to finish.

#12 Create a Modernization Roadmap

You are now prepared to create a modernization roadmap based on your business understanding, the current condition of your application, and your long-term goals.

The data you gathered in earlier phases will guide the creation of your application modernization roadmap.

#13 Roadmap Development

Defining a viable modernization roadmap that precisely stipulates various components, schedules, resource needs, and dependencies is highly important.

Specify the main stages, achievements, and success factors that will be applied in each phase of the innovation process.

#14 Change Management

Create a change management strategy to facilitate the organizational transition, communication with stakeholders, and user interactions with modernized solutions.

Offer training, conversation, and guidance to the employees to guarantee a successful transition and to overcome resistance to change.

#15 Governance and Monitoring

Set up the governance apparatus to measure and monitor the progress of modernization measures. Establish a monitoring and reporting surveillance mechanism targeting the achievement of KPIs and metrics as set previously.

#16 Continuous Improvement
