It will be insightful if more people share how they manage, internally, the many different apps that they have adopted within their ecosystem. Especially how, from a solutions architect point of view, that they let all these co-exists and even complement each other. Is there some common layer/web-service/file import-export that is done whenever apps work with other apps?
I can share from my experience about why I used to use open source apps a lot, and how I kept them in step with each other...and also why my other engagements did not want to go there.
It will be good if we use this chance to learn what options are out there for letting these systems all work together...interoperability is probably a good tag word for this.
The session's content is not cast in stone yet. Feel free to suggest more things that you may want to chip in and share about, or want me to research a little and bring up during the session. I simply miss getting everyone together for a drink, hence this excuse for another chat.
