This modular approach enables easier management, scalability, and faster deployment of new features. Each microservice can be developed, tested, and deployed independently, reducing the risk of system-wide failures and facilitating continuous integration and continuous delivery (CI/CD).
DevOps Integration
Integrating DevOps practices into the modernization process is essential for achieving continuous delivery and integration. DevOps fosters a culture of collaboration between development and operations teams, streamlining workflows and reducing bottlenecks. A study by Puppet shows that organizations implementing DevOps practices report a 206 times more frequent code deployment (source: Puppet). By automating repetitive tasks as part of legacy system modernization and implementing CI/CD pipelines, organizations can accelerate development cycles, improve system reliability, and enhance overall performance.
Low-Code and No-Code Platforms
The adoption of low-code and no-code platforms is transforming how legacy systems are modernized. According to a report by Forrester, low-code development is expected to grow to a $21 billion industry by 2022. These platforms enable faster development by allowing users to create applications with minimal or no coding required. They are particularly useful for modernizing legacy systems as they reduce the time and effort needed to build and deploy new functionalities around budget constraints.
