Number six is "Subsystems - Hostel or hotel?"
Here's my favorite excerpt from the chapter:
IBM i subsystems are the business hotel rooms of the operating system world. Within one image, subsystems isolate database and application workloads, matching resources and priorities to business service goals. They are, very simply, designed for business.
More like hostels, x86 operating systems are not designed to isolate workloads; if one process fails, it may affect another. To avoid conflicts, applications and databases are typically run in separate virtual machines or servers—they’re moved to a different hostel.
Plus, there's a new video by IBM's chief architect for IBM i, Steve Will:
And number seven? "7. Object orientation – May I see your badge, please?"
IBM i was designed to be object-based, meaning the operating system will ensure that each of the hundreds of object types entering the system will behave predictably and within the limits of a user's authority. Object-oriented security helps protect IBM i against malware or other malicious attacks and is the foundation for its well-earned reputation as one of the most secure IT systems for business.
In any event, there's all sorts of IBM i goodness going on here, and it's worthwhile to check out the celebration, if only to bone up on IBM i awesomeness. As for Facebook likes, IBMi25 is up to nearly 1,100.
