These organizations leverage top-notch application modernization tools to ensure the continued operation of their legacy software.
Modernizing legacy systems involves updating, upgrading, and improving their features, infrastructure, and architecture.
Legacy system modernization addresses constraints and ensures compliance with modern standards, security, and evolving business needs. The modernization of legacy systems empowers organizations to improve operational efficiency, scalability, and overall performance. This, in turn, positions them for enduring success in the dynamic digital landscape.
Understanding the Need for Legacy Application Modernization for Businesses
Older legacy systems struggle to keep up with today’s rapid technological changes and competitive demands. While numerous legacy systems remain indispensable for business operations, the choice to modernize becomes pivotal as IT managers and executives assess the enduring maintenance costs vis-à-vis the advantages of application modernization.
The aging systems have dutifully fulfilled their roles, but their capacity to adjust to the dynamic contemporary business environment is constrained. Modernization goes beyond mere technological updates; it constitutes a strategic initiative to unlock heightened efficiency, superior performance, and the capability to stay ahead in a competitive market.
As per McKinsey, legacy systems significantly impede business performance, posing challenges in terms of maintenance costs and hindering the adoption of new technologies and innovative business models due to their complexity and high expenses associated with upgrades.
Deloitte emphasizes modernizing applications for enhanced flexibility and agility, aligning IT with specific business needs. Legacy applications, particularly those relying on mainframes, encounter compatibility issues with modern platforms. This constraint hampers organizations’ capacity to meet crucial business requirements and capitalize on future growth opportunities.
Legacy System Modernization Strategy Crucial to Your Business Success
Digital transformation involves a comprehensive effort by an organization to boost productivity, foster creativity, and drive growth. A strategic legacy modernization plan significantly contributes to an organization’s digital transformation journey, aligning with the people-process-technology triangle.
Modernizing legacy systems, particularly those based on older application versions, presents challenges due to their custom-built single monolith style in contrast to a microservices model. In this setup, the software components—data, network configurations, and security—are intricately interwoven with the foundational infrastructure, making it challenging to upgrade individual elements. The process involves assessing your company’s requirements, determining which aspects to update initially, selecting a dedicated legacy system modernization strategy, and implementing it.
Establish Your Software Modernization Goals
Transitioning from your COBOL/CICS environment (a programming language that has been in use for 60 years and remains relevant) to Java does not offer a one-size-fits-all solution. It is recommended to synchronize modernization efforts for legacy software with your business and technological goals, emphasizing scalability, incorporation of additional features, and achieving a quicker time-to-market.
Identify the Issues
Another crucial element of the strategy for modernizing legacy applications involves bug detection. If the old system fails to align with current organizational or IT requirements, it becomes imperative to delve deeper into identifying the issues. Examine the shortcomings in your digital solution that may be causing frustration for users. Select the appropriate user stories for a thorough understanding of the problems.
Assess Modernization
The analysis of legacy modernization requires a methodical approach, encompassing the identification of needs, evaluation of the current status, exploration of modernization possibilities, and the formulation and execution of a comprehensive modernization strategy.
Choose the Architecture
In this stage, it is crucial to identify the optimal architecture or legacy modernization approach across three key levels: application, database, and platform/server. This decision should be based on the chosen strategy.
Would you prefer the platform/server to be in the cloud to minimize capital expenditures (CapEx) and increase operational expenditures (OpEx), or would you rather have it in your data center for greater control?
If the program is functioning well in its current state, do you opt for a more economical, open-source database like MySQL or Postgres? To make this transition, the program will need to undergo re-platforming to integrate with the new database.
Are you looking to shift both the application and the database to the cloud, replacing your data center? This choice entails higher immediate costs but promises long-term reductions in IT staff.
While the enterprise architect is tasked with making these decisions, the business is also impacted. The chosen architecture must be capable of supporting automated processes and technologies such as DevOps, DataOps, and other pipeline delivery paradigms to attain the desired level of acceleration and value.
Selecting the Team to Execute the Plan
Ensuring the successful implementation of legacy application modernization solutions requires partnering with the appropriate team. The typical personnel hierarchy for most legacy application modernization initiatives follows the structure outlined below:
The program is overseen by top-tier executives in the C-suite, including the Chief Information Officer (CIO), Chief Technology Officer (CTO), Chief Information Security Officer (CISO), and Chief Security Officer (CSO).
The business and IT teams act as liaisons for their respective communities.
The enterprise architecture team harmonizes IT capabilities with the business community’s requirements for goods and services. Additionally, the team is responsible for delineating the details of a strategy to modernize outdated applications, aligning with the overarching business goal.
Establishing Success Metrics
The most effective approach to gauge the success of your legacy application modernization is to choose metrics aligned with your initial motivation.
The deeper your understanding of data, the greater the insights you’ll gain to enhance the modernization of your legacy applications.
Implement Automation for Modernization
The objective of modernizing legacy software is to enhance value for the company, requiring a focus on automation. A fully automated migration, involving the refactoring of legacy data and code to contemporary platforms, proves to be a more efficient method for accomplishing legacy modernization.
Furthermore, this approach enables organizations to seamlessly introduce digital modernization without disrupting daily operations.
Initiate Monitoring
The benefits of modernizing legacy applications may not be immediately evident, as persistent challenges may arise. Therefore, as the project approaches its conclusion, your strategy should encompass monitoring and optimization. When exploring available tools, consider the following factors:
Ensure that the modernized application aligns with corporate goals and adheres to budget constraints by devising methods to track its performance.
In case the modernization of legacy applications involves the use of the cloud, keep a close watch on both the environment’s performance and the cost of cloud computing. While many businesses leverage the cloud to reduce expenses, prudent usage is essential to realize any financial savings.
