Das Standardwerk zur Softwarearchitektur - Schließt die Lücke zwischen Softwarearchitektur und Implementierung der Codebasis - Einfache und übersichtliche Strukturierung aller wichtigen Grundkonzepte im Bereich der Softwarearchitektur - Mit über 200 farbigen Bildern aus real existierenden Softwaresystemen und etlichen FallbeispielenJe nachdem, wo Sie gerade stehen, ob Sie ein neues Entwicklungsprojekt planen oder das Ausmaß an technischen Schulden in einem bestehenden System reduzieren wollen, in diesem Buch finden Sie die passenden Antworten, um zu verhindern, dass die Architektur Ihres Systems erodiert, die Komplexität zunimmt, ständig weitere technische Schulden entstehen und Wartung und Erweiterung immer aufwendiger werden. In diesem Buch zeigt Ihnen die Autorin, worauf Sie bei der Umsetzung der Architektur achten sollten und welche Prinzipien eingehalten werden müssen, damit Sie in Ihren Softwareprojekten langlebige Architekturen entwerfen oder Ihre bestehenden Systeme durch kleine und große Refactorings in langlebige Architekturen überführen können. Es werden Muster in Softwarearchitekturen und Mustersprachen sowie verschiedene Architekturstile erläutert und aufgezeigt, welche Vorgaben letztlich zu Architekturen führen, die für Entwickler noch gut durchschaubar sind. Mit über 200 farbigen Bildern aus real existierenden Softwaresystemen und etlichen Fallbeispielen werden schlechte und gute Lösungen verständlich und nachvollziehbar dargestellt. Empfehlungen und vielfältige Hinweise aus Praxisprojekten erlauben dem Leser einen direkten Transfer zu seiner täglichen Arbeit. In der 4. Auflage wurde dem Thema Modularity Maturity Index (MMI) ein eigenes Kapitel gewidmet und der Text inhaltlich so erweitert, dass der gesamte Algorithmus zur Berechnung des MMI zugänglich wird. Nun kann jedes Team den MMI für sein System selbst bestimmen.

Author Matthew Dowst uses his decades of experience to lay out a real blueprint for setting up an enterprise scripting environment with PowerShell. The book goes beyond the basics to show you how to handle the unforeseen complexities that can keep automations from becoming reusable and resilient. From the console to the cloud, you'll learn how to manage your code, avoid common pitfalls, and create sharable automations that are adaptable to different use cases. About the Technology The PowerShell scripting language is a force multiplier, giving you programmatic control over your whole data center. With this powerful tool, you can create reusable automations that radically improve consistency and productivity on your Ops team. This book shows you how to design, write, organize, and deploy scripts to automate operations on systems of all sizes, from local servers to enterprise clusters in the cloud. About the Book Practical Automation with PowerShell: Effective scripting from the console to the cloud shows you how to build PowerShell automations for local and cloud systems. In it, you'll find tips for identifying automatable tasks, techniques for structuring and managing scripts, and lots of well-explained example code. You'll even learn how to adapt existing scripts to new use cases and empower non-technical users through easy-to-understand SharePoint frontends.

In many systems, scalability becomes the primary driver as the user base grows. Attractive features and high utility breed success, which brings more requests to handle and more data to manage. But organizations reach a tipping point when design decisions that made sense under light loads suddenly become technical debt. This practical book covers design approaches and technologies that make it possible to scale an application quickly and cost-effectively.Author Ian Gorton takes software architects and developers through the foundational principles of distributed systems. You'll explore the essential ingredients of scalable solutions, including replication, state management, load balancing, and caching. Specific chapters focus on the implications of scalability for databases, microservices, and event-based streaming systems.You will focus on:Foundations of scalable systems: Learn basic design principles of scalability, its costs, and architectural tradeoffsDesigning scalable services: Dive into service design, caching, asynchronous messaging, serverless processing, and microservicesDesigning scalable data systems: Learn data system fundamentals, NoSQL databases, and eventual consistency versus strong consistencyDesigning scalable streaming systems: Explore stream processing systems and scalable event-driven processing
