Description
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.Topic Highlights:- Network Zones, Components, and Scenarios- Load Distribution- Firewalls and Application Gateways- Application Security, Security Zones, and Access Control Lists- High Availability and Clustering- Sizing and Load Testing- Application and Network Performance- Terminal Server, Web Cache, and Virtual Private Networks
