Abstract
Recent global changes have impacted IT. Organizations are accelerating digital transformation to support an increasingly always-on world. IT leaders are focused on modernizing critical processes and operations to gain a competitive advantage in this dynamic environment.
Application modernization (updating applications to improve maintenance, extension, deployment, and management) is essential to meeting current and future needs. It provides numerous business and technical benefits.
Modernizing existing enterprise applications enables a smoother migration to hybrid cloud, offering the flexibility to run applications anywhere at any time. A cloud-native microservices approach maximizes the scalability and agility of the cloud.
Modernizing IBM Power allows new cloud-native microservices to integrate with existing applications by using the platform’s performance, reliability, and security. This approach removes integration and productivity barriers, enabling enhanced user experiences, new applications, and new business opportunities.
This IBM Redbooks® publication provides a high-level overview of modernization, including key concepts and terminology to guide your modernization journey. It explores the components and architectural layers of the IBM Power ecosystem, demonstrating how they create an ideal platform for running mission-critical applications. The content is intended for business leaders, architects, and application developers.
