High Availability

Achieving High Availability for SAP Solutions

To gain competitive advantage, you need to think collaborative business. This means integrating existing heterogeneous system landscapes to include business partners, customers, and suppliers. 

Today the trend is toward open system architectures in which end-to-end business processes combine Web services running on multiple distributed application components. Such environments demand high availability not only for single components, but also for entire scenarios.

 

SAP has worked with its partners to develop a range of high availability solutions, already in use by many customers. Our documentation guides you through the challenging area of high availability and shows where you can best direct your effort and expenditure.

 

The solutions you choose - very likely some of them third-party - vary according to your system landscape. Be sure to discuss your plans with your SAP consultant and hardware partner before implementation. Refer also to the SAP NetWeaver Application Server.
