What is application modernisation?

What are 3 modernisation focus areas?

• Cloud migration involves transitioning existing applications to a cloud environment, providing scalability, cost efficiency, and leveraging cloud services. This allows businesses to scale their infrastructure dynamically and manage resources more effectively.
• Low code development accelerates app development and modernisation efforts by enabling non-developers to create applications with minimal coding, thus reducing development cycles and fostering innovation.
• Enhanced security measures are crucial for protecting modernised applications from emerging threats. Implementing advanced security protocols ensures data integrity, compliance with regulatory standards, and the safe operation of modernised systems in an increasingly complex digital landscape.

What is the biggest driver of application modernisation?

The biggest driver of application modernisation is the need to stay competitive in today's fast-paced business environment. Modernising legacy systems and applications enhances operational efficiency and responsiveness, allowing businesses to adopt emerging technologies like artificial intelligence and machine learning. This digital transformation ensures that organisations can meet evolving customer demands, reduce technical debt, and leverage cloud native development for future growth.

What is the future of application modernisation?

The future of application modernisation lies in embracing cloud native platforms, hybrid cloud technology, and continuous integration. Businesses will increasingly adopt cloud native applications to leverage scalability and flexibility. Hybrid cloud technology will provide a balanced approach to data control and scalability, while continuous integration practices will ensure faster development cycles and improved system reliability. These modernisation trends will drive innovation, enhance operational efficiency, and maintain a competitive edge in the digital age.

What is the framework for app modernisation?

The framework for app modernisation includes several key components: assessment and planning, prioritisation, approach selection, and continuous improvement. First, evaluate existing applications and set clear modernisation goals. Next, prioritise high-value applications, considering factors like technical debt and potential for improvement. Select the best modernisation approach, such as re-platforming, refactoring, or cloud migration techniques. Finally, ensure continuous improvement by leveraging modernisation trends and refining the application modernisation strategy based on evolving business needs.

Why is application modernisation difficult?

Application modernisation is difficult due to the complexity of legacy systems and the need for a comprehensive modernisation approach. Modernising legacy applications often involves significant technical debt, outdated systems, and the challenge of integrating with new technologies like cloud native development and no code platforms. Additionally, ensuring enhanced security, data integrity, and seamless business operations during the modernisation process requires careful planning and execution. Despite these challenges, a well-defined application modernisation strategy can lead to long-term success and sustainability.

Importance of application modernisation

Application modernisation plays a pivotal role in digital transformation. It offers a competitive advantage by enabling businesses to operate more efficiently, innovate faster, and comply with regulatory requirements. Modernised applications are easier to maintain, scale, and secure, ensuring that businesses can adapt to changing market demands and technological advancements.

Top 15 Application Modernisation Trends in 2024

1. Cloud native development: Cloud-native development leverages technologies like containers and microservices to create flexible, scalable, and cost-effective applications. This approach allows businesses to quickly deploy and manage applications in the cloud, improving agility and reducing costs.
2. Hybrid cloud technology: Hybrid cloud technology combines public and private clouds, offering improved data control, scalability, and flexibility. Businesses can benefit from the security of private clouds while taking advantage of the scalability and cost-effectiveness of public clouds.
3. Low-code/No-code development: Low-code and no-code platforms enable non-developers to create applications, speeding up development and reducing costs. These platforms democratise app development, allowing businesses to quickly respond to changing needs.
4. Progressive Web Applications (PWA): PWAs provide offline functionality, fast loading times, and cross-device compatibility. They offer a seamless user experience similar to native apps but with the accessibility of web applications.
5. AI and ML integration: Integrating AI and ML in applications can automate processes, enhance decision-making, and improve user experiences. Use cases include predictive analytics, personalised recommendations, and intelligent automation.
6. Legacy infrastructure modernisation: Updating legacy infrastructure is crucial for maintaining performance and security. Approaches like re-platforming, refactoring, and repurchasing can extend the life of existing systems while enhancing their capabilities.
7. DevOps methodology: DevOps practices promote faster release cycles, enhanced collaboration, and increased efficiency. By integrating development and operations, businesses can streamline workflows and improve product quality.
8. Containerisation: Containerisation simplifies deployment, improves portability, and enhances scalability across different environments. Containers package applications and their dependencies, ensuring consistent performance.
9. Composable architecture: Composable architecture uses modular, reusable components to speed up development and improve scalability. This approach enables businesses to quickly assemble and reconfigure applications to meet changing needs.
10. Microservices architecture: Microservices architecture breaks applications into smaller, independent services that can be developed, deployed, and scaled separately. This modularity simplifies maintenance and enhances scalability.
11. Infrastructure as Code (IaC): IaC automates infrastructure management, ensuring consistency and efficiency in deployment. By treating infrastructure as software, businesses can easily replicate environments and manage changes.
12. Blockchain integration: Blockchain technology enhances security, transparency, and data integrity. Its applications in modernisation include secure transactions, data sharing, and supply chain tracking.
13. Robotic Process Automation (RPA): RPA automates repetitive tasks, increasing efficiency, reducing errors, and freeing up human resources for more complex tasks. It is widely used for data entry, processing transactions, and generating reports.
14. API-first development: API-first development focuses on creating scalable and flexible applications that easily integrate with other systems. This approach promotes interoperability and speeds up development.
15. Enhanced security measures: Robust security is crucial in application modernisation. Trends like zero-trust architecture, advanced encryption, and proactive threat detection help protect applications from evolving threats.

How to implement an effective application modernisation strategy

1. Assessment and planning: Evaluate current applications and set clear modernisation goals aligned with business strategy.
2. Prioritisation: Prioritise high-value applications considering factors like technical debt and potential for improvement.
3. Approach selection: Choose the best modernisation approach (re-platforming, refactoring, repurchasing) based on business needs.
4. Incremental modernisation: Break down modernisation into manageable phases and ensure thorough testing at each stage.
5. Continuous improvement: Continuously monitor, gather feedback, and refine modernisation strategies to meet evolving needs.
