SAP has a pretty catchy new spin since 2014 with the slogan “Run Simple”, well maybe for the business and end-users, but as far as the Basis team is concerned, managing the sprawling SAP landscapes and lifecycle is anything but simple. In my experience, the move to newer SAP technologies (such as HANA, Sybase, BOBJ, virtualization, cloud, etc.) has proliferated more requirements and demands on the Basis, Infrastructure and IT Operations teams. One example of this includes new deployments of SAP HANA which may scale out a Production environment up to 16 nodes. That is anything but simple. But I’ll play along that if you consolidated all your SAP environments into this huge HANA cluster, then it may look simple like in the old days when there was only R/3 and everything ran on it. However, if you’re going to put all your eggs into one basket, then you’ll need to protect it with a Business Continuity strategy for HA and DR which would no doubt be very complex.
A few years ago, I was able to install and take test drive of SAP ACC (Adaptive Computing Controller) when it was version 1.0, and the idea was quite exciting for a Basis administrator to be able to control SAP on the virtualized environment. If you ever worked on high availability SAP systems, you would know it's quite complex to monitor, manage and control the resources and where they run on the underlying infrastructure. At the time, almost nobody used ACC except for a few customers who were working closely with hardware vendors such as IBM who co-innovated the product with SAP.
