Software and infrastructure only create value when they pull in the same direction as the business. This book shows IT leaders how to get there: from shaping IT strategy and the architecture roadmap to the daily discipline of IT and architecture governance, all built on a pattern-based approach that adapts to your organization rather than forcing it into a template.Grounded in established frameworks such as TOGAF, COBIT, and ITIL, it pairs solid fundamentals with numerous real-world examples — and gives growing weight to compliance and IT security, now central concerns of any IT management agenda.This English edition is based on the German standard work on the subject, fully revised in its 4th edition (late 2024). It is current with TOGAF 10 and reflects recent developments in business-oriented enterprise architecture — including the open-source tool EDGY and patterns for digital strategy — alongside the latest trends in IT risk management and cybersecurity architecture.

What you've got here is a hands-on walkthrough of Spring Boot 4.0, where we'll build a single application from start to finish, using the command line and then packaging it as a JAR at the end.

Each chapter gets straight into the code, and you can run, modify and break it to see what happens.There's even a dedicated troubleshooting chapter at the end that deals with the exact errors beginners actually encounter in practice, not just hypothetical ones.
