Softcover. Zustand: gut. 2008. An increasing number of business scenarios require employees, customers and partners to be connected via the Web. Therefore, in order to implement business Web applications using the SAP NetWeaver Portal, you'll need to have the right system landscape infrastructure in place. This begs important questions such as: Can I use my existing infrastructure for internal and external applications simultaneously? Where does my database fit into this kind of scenario? How should I handle user management? How can I incorporate my back-end system into the system landscape? What about making this landscape secure, both internally and externally? How will the stability of the system be maintained as the number of accesses increases? These are precisely the questions that this in-depth technical guide from SAP PRESS aims to answer. With its practical focus on application and infrastructure know-how, this book deftly supports system administrators, network architects, technical consultants, and security experts in making key decisions on how best to create a complex web infrastructure that fulfills all the latest security requirements. Several detailed examples shed additional light and serve to complete the intricate, yet straightforward, picture painted by the authors.

Hardcover. Zustand: gut. 2007. Immer mehr Geschäftsszenarien setzen die Anbindung von Mitarbeitern, Kunden und Partnern über das Internet voraus. Um solche Business Web Applications über das SAP NetWeaver Portal umzusetzen, stellt sich die Frage nach der richtigen Infrastruktur der Systemlandschaft: Kann ich meine bestehende Infrastruktur gleichzeitig für interne und externe Applikationen nutzen? Wo platziere ich in einem solchen Szenario die Datenbank? Wie wickle ich das Usermanagement ab? Wie bringe ich meine Backend-Systeme in den Systemverbund? Wie sichere ich diese Landschaft von innen und außen ab? Wie bleibt das System auch bei steigender Zugriffszahl stabil? Genau diese Fragen, wie eine Web-Infrastruktur im SAP-Umfeld aufgebaut und designt werden muss, beantwortet dieses SAP-Heft. Durch eine Mischung aus Anwendungs- und Infrastruktur-Know-how erhalten Systemadministratoren, Netzwerkarchitekten, technische Berater und Sicherheitsexperten einen Entscheidungsleitfaden, wie eine komplexe und gleichermaßen modernen Sicherheitsanforderungen genügende Web-Infrastruktur aufgebaut sein muss. Zahlreiche Praxis- und Projektbeispiele runden die Darstellung allumfassend ab.
