Enterprise Systems Architecture

Sharing the full video ,2hr 45 minutes, of my recent seminar delivered to the MBA Students of the American University in Cairo (AUC).  I recommend skipping 1.30-1-55 of the video as this was the break period, as the camera was left on. There is a lot of content with some great questions - hope you find it useful.

Let me start by apologising, as todays blog can be considered, by some , as content of little value to support macro EA views and a topic where information can be sourced easily via the web or by using AI tools (fast becoming everyday tools). However I felt I would   share this reference type  material, as error codes are always required for those building information systems. FYI recently I had to examine various  http error codes used in  a Cloud based API management system in respect of the flows of  message exchanges and conduct analysis of non-typical scenarios e.g. a missing authentication token resulting in an invalid exchange between the backend and the API Gateway. Under normal operational conditions, interactions between two or more system will result in the exchange numerous codes which notify each system of task status e.g. a 200 return code will represents that all is well and allows the process continuation of further orchestration of a workflow to complete its task.
