Creating Business Value with the IoT, Part 2
Plan Ahead to Leverage Existing IT Investments
In this video, Ken Johnson, Senior Director of Product Management at Red Hat, talks about the IoT architectural shift that developers should consider early in the project lifecycle in order to make the best use of existing IT investments.

Adrian Bowles: I’ve got a problem. You’re going to build something for me and it-
Ken Johnson: Yeah. It’s pretty bounded. In an IoT realm, the systems tend to be distributed. The applications are distributed. You’re breaking application logic over multiple tiers and you need to think about that early in the process, not that you have to have a waterfall approach. I’ve had it in exactly the specified end state, but you have to consider where the components are going to run, what your distributed architecture looks like. You’re bringing more physicality into your application.
It’s not just I’m running software on a server or on a computer but I’m running in tiers of architecture which may be very highly distributed, may be physically constrained, may be on mobile assets. I do have to think about what my physical topology is going to look like and start my prototyping with that in mind. The technology selections you’re going to make up front to prototype need to
support, or have a path to support, the eventual deployment architecture you’re envisioning. If you go, say, with a complete cloud only backend with a simple device to cloud model and you anticipate needing to have a mid-tier, a gateway tier, on a mobile asset, how are you going to retrofit that in later without rearchitecting your application?
You need to think about that up front and as you start prototyping, whether you virtualize that, or do a simplistic multitier model, start with that. You can understand how you’re going to divide your logic, understand the network considerations, the device communication patterns, and things that are going to exist in the real end state you’re envisioning. If you oversimplify in the prototype stage, when you get closer to reality you’ll have a problem on your hand in terms of going to refit your simplified prototype to the actual reality. Have the end state reality in mind, but simplify that as much as you can.
Have it be representative of the real world that you’re going to be deploying this in so you can be sure you have the right software selected, the right skills, the right tools to build the right functionality at each of the tiers, and be able to distribute it, be able to manage it, be able to run it effectively.
