Yes, I know what you must be thinking but this is right, with SAP’s newest technology i.e. Accelerated Application Delivery also called AccAD it has become possible. Performance has always been an issue while running web applications (SAP Portal, CRM Web Applications, BI Web Report etc.) over WAN and we haven’t seen any concrete solution addressing that challenge. Now that companies operating worldwide and the business processes are integrated and more streamlined and used across all geographical locations, there is a need to have a system which is centrally managed and easily accessed from anywhere (web). Now we all know the answer to that this was addressed by having a global instance of SAP Enterprise Portal which can be accessed by anyone and from anywhere. For example, you have SAP HR Portal, hosted in a Data Center either outsourced or in-premise and the Users from all over the world (India, China, Europe, Africa and Australia) access the portal related to their HR activities as shown below:
However with that, come the problems of Limited Bandwidth, High Latency, Network Traffic, Caching, Compression etc
AccAD provides you global connectivity over WAN as if you are running the applications in LAN. Well are you overjoyed? Wait till you read this statement, “AccAD is a complimentary offering for SAP NetWeaver and available for download to all customers”. It’s a standalone product and can be installed and setup easily with the existing Portal solution. It has mainly 2 components i.e. 1) SFE (Server Front-End) and 2) CFE (Client Front-End). SFE is the interface b/w Portal Server and WAN and CFE is the interface b/w end-user’s machine and WAN. See below:
So with AccAD in place the Image 1 will look like:
I have experienced user’s complaining about the performance of the system even if the portal/J2EE engine is configured for the best possible performance. The distance between the client and the server is certainly an important factor while measuring performance and can not be ignored. AccAD virtually moves the application closer towards the end-user. So if you are in a similar situation where you have a global instance of SAP Enterprise Portal and the user base is spread all over the world, use of AccAD is highly recommended. Now I don’t know how many customers are running this in their landscape at the moment (probably SAP can share that), but it’s certainly looks promising, so give it a try!!!
