Quick Read: Main Points
- 2025 serves as a significant benchmark for revitalising legacy systems, propelled by AI innovations.
- Legacy systems impede AI integration because of their inflexibility, expensive upkeep, and inability to accommodate contemporary applications.
- AI-based solutions can significantly reduce both the duration and expenditure associated with modernising legacy systems.
- Case Study: Bendigo and Adelaide Bank slashed migration time by 90% through AI-enhanced modernisation.
- Firms must explore AI-led modernisation to maintain a competitive edge.
Why Legacy Modernisation is at a Critical Juncture
The year 2025 is poised to become a transformative period for Australian companies, as the urgency to update legacy systems reaches a peak. The emergence of AI and its potential for transformation mean that businesses that do not upgrade their infrastructure risk being left behind. AI requires timely, unstructured, and intricately connected data, which legacy systems, like relational databases, struggle to supply. Enterprises that take years to adapt their infrastructure for AI applications will find themselves too late to compete in the rapidly evolving AI-focused market.
IDC forecasts indicate that the worldwide AI market could hit $631 billion by 2028, underscoring that immediate action is essential. Yet, AI not only intensifies the demand for modernisation but also presents new solutions that were not available before.
The Legacy System Dilemma
Legacy systems, which account for about one-third of an enterprise’s technology framework, are a costly and complicated liability. Upholding these outdated systems may consume as much as 80% of an IT budget, leaving scant opportunity for innovation. CIOs frequently mention legacy systems as one of their top challenges, second only to cybersecurity issues.
Main Issues with Legacy Systems
- Inflexibility: Developers dedicate 42% of their time to maintaining systems rather than innovating, restricting agility.
- Exorbitant Costs: Firms expend billions on antiquated hardware, licensing costs, and cloud dependencies.
- Incompatibility: Legacy systems obstruct modern AI applications due to their rigid designs.
Without modernisation, organisations struggle to tap into their valuable data to create intelligent, AI-powered applications. Instead, they risk putting together shallow solutions that do not fully leverage their data capabilities.
AI Transforms Legacy Modernisation
Traditionally, modernising legacy systems has been viewed as a lengthy, costly, and uncertain venture. However, AI-enhanced solutions are shifting that paradigm. By incorporating Large Language Models (LLMs) and proprietary tools, companies can expedite modernisation and cut expenses. These AI-infused processes tackle various challenges, making modernisation more achievable and effective.
Essential AI-Driven Modernisation Techniques
- Code Evaluation: LLMs can scrutinise legacy codebases to discern their structure, minimizing reliance on original developers.
- User Engagement Analysis: AI can monitor user interactions with applications, generating automated tests to ensure new systems function smoothly.
- Microservices Streamlining: LLMs can semi-automate the development of microservices based on existing code and user behavior.
These innovations enable quicker and more economical modernisation than ever before.
Case Study: Bendigo and Adelaide Bank
An exemplary case of AI-powered modernisation is Bendigo and Adelaide Bank. The bank effectively updated a core banking application using AI, attaining impressive outcomes:
- Migration developer time reduced by 90%.
- Testing duration diminished from 80 hours to merely 5 minutes.
- Expenditures cut down to one-tenth of traditional migration costs.
Building on this achievement, the bank is now replicating the process for other core applications, establishing a standard for what AI-enhanced modernisation can accomplish.
Creating an AI-Powered Modernisation Factory
Organisations should start by testing a single application to grasp the advantages of AI-led modernisation. This method allows teams to develop a playbook and set up tools for extending the process across additional applications. By doing so, businesses can establish a modernisation factory that guarantees consistent and effective transformation of their legacy systems.
Conclusion
2025 represents a critical juncture for Australian businesses as they encounter a “now or never” scenario for modernising legacy systems. With AI propelling both the necessity and the resolution, organisations can no longer afford to postpone. By utilising AI-driven tools and methodologies, enterprises can rejuvenate their outdated infrastructure into a modern, AI-ready technology framework, ensuring competitiveness in an increasingly data-centric landscape.
Q&A: Frequently Asked Questions About Legacy Modernisation
Q: Why is 2025 seen as an essential deadline for legacy modernisation?
A:
2025 signifies a pivotal point owing to the swift progress in AI and its dependence on contemporary, scalable infrastructure. Organisations that postpone modernisation are likely to lag behind in an ever more competitive and AI-focused market.
Q: What are the primary difficulties associated with legacy systems?
A:
Legacy systems are inflexible, costly to maintain, and incompatible with modern technologies like AI. They can consume up to 80% of IT budgets and stifle innovation by confining data within silos.
Q: In what ways can AI assist in modernising legacy systems?
A:
AI can assess legacy code, enhance user experiences, and automate processes like microservices creation, considerably decreasing time, costs, and complexity involved in modernisation.
Q: What constitutes a modernisation factory?
A:
A modernisation factory represents a scalable strategy whereby organisations establish a repeatable methodology to systematically modernise applications, drawing on AI and insights gained from initial trials.
Q: Are there notable instances of successful AI-driven modernisation in Australia?
A:
Indeed, Bendigo and Adelaide Bank effectively modernised a core banking application, achieving a 90% reduction in migration time and costs, highlighting the promise of AI-driven modernisation.
Q: What should organisations focus on when initiating modernisation?
A:
Begin with a small-scale experiment to modernise one application. This allows the organisation to validate AI-driven methods, build expertise, and efficiently scale modernisation initiatives.
