with Jim Christopher, PowerShell MVP

In this session, I'll talk about one of my clients – let's call em “Client O”. Over the last eight months, I’ve been working with Client O to migrate their enterprise software application from a monolithic web service to a loosely-coupled, message-centric architecture based on MSMQ (Microsoft Message Queue). The results have been remarkably positive: their processing capacity is currently over 800% of where they started, and they have the ability to scale even higher if necessary. In addition, their error rate has fallen by about 96%. However, alongside these successes are colossal new problems for the organization – specifically, the new highly-dispersed architecture represents a serious challenge for the barebones systems management team.

This session will tell the story of this system-in-flux, and discuss ways to resolve the problems caused by the system’s success. I will include a technical overview of the legacy system and the migration to the queue-based architecture. Specific attention will be given to assumptions in the legacy system that prevented scaling, and how these assumptions were addressed with message queues.
