Abstract
The rapid global changes of recent years have significantly impacted IT. Organizations are accelerating their digital transformations to support an increasingly always-on world. IT leaders are focused on modernizing critical processes and operations to gain a competitive edge in this dynamic environment.
Application modernization updating applications for improved maintenance, extension, deployment, and management is key to meeting current and future needs. It offers numerous business and technical advantages.
Modernizing existing enterprise applications facilitates a smoother transition to hybrid cloud, providing the flexibility to run applications anywhere, anytime. A cloud-native microservices approach maximizes the scalability and agility of the cloud.
Modernizing on IBM Power allows new cloud-native microservices to integrate with existing applications, leveraging the platform's performance, reliability, and security. This removes integration and productivity barriers, paving the way for enhanced user experiences, new applications, and ultimately, new business opportunities.
This IBM Redbook offers 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 in today's world. The content is designed for business leaders, architects, and application developers.
