Software technology changes rapidly. Many new tools and techniques arrive in the software engineering realm to take on old and new problems. There are still big architecture and implementation holes yet to be addressed. For example, as a few billion more smart phones, tablets and internet connected sensing devices come online across the world, how are they all going to discover and utilize all the available resources collaboratively?
One of the current problems with most existing architectures is data gets routed through central servers in a data center somewhere. Typically software systems are still built using client/server architectures. Even if an application is using multiple remote sources for data, it’s still really just a slight variation. Service and data lookups are done using a statically defined address rather than through discovery. Even remote sensing and home automation devices barely collaborate locally and require a local router to communicate with a remote server in a data center.
In the past month, I have been to both the Internet of Things World and Augmented World Expo (AWE). At both of these excellent conferences, there was at least some discussion about the need for a better infrastructure
- to connect devices in a way to make them more useful through collaboration of resources and
- to connect devices to provide capabilities to share experiences in real time.
But it was just talk about the need. No one yet is demonstrating any functional capabilities in this manner.
On a side note: I saw only one person, out of 3000 or so, at the AWE conference wearing a device for augmentation. It was Steve Mann who is considered the father of wearables. I dare say that most proponents of the technology are not ready to exhibit it nor is the infrastructure around to support its use effectively. There is great work progressing though.
Peer-to-peer architectures used in file sharing and the architecture Skype uses start providing directional guidance for what is to come in truly distributed architectures. Enhancing these architectures to include dynamic discovery of software and hardware resources and orchestrating dynamic resource utilization is still needed.
There are a few efforts in development beginning to address some of the internet-wide distributed computing platforms needed for data sharing, augmented reality and machine learning. Those of you thinking of batch jobs or wiring up business services as distributed computing, this is not what I’m talking about. I am talking about a small footprint software stack able to execute on many different hardware devices with the ability for those devices to communicate directly with each other.
If you know about development efforts in this vain, I would like to hear about them.
