Agile, Emergence and Deliberate Design

Emergence is good, but…

Emergence is good, but…

…it takes time, and

…under some circumstances it may not happen!

If you have been there … done that … then you don’t have to wait for your application architecture to emerge over several iterations. You can use your past experience to nail it down at the beginning.

However, if all the team members are new to the problem or the technology – experimentation, trail and error would be need to arrive at the design and architecture.

Alternately, the team can take the help of a specialist who can get them going. This can cut down lot of exploration into blind alley. You may feel that it is be better to learn the hard way but imagine if we had to learn everything by ourselves from scratch – you may have to start by inventing the wheel!

So, a good question to ask is…

…where do you draw the line between the allowing the design to emerge and doing an upfront and deliberate design?

…to what detail should go?

…how much of external help should you take?

Recently, IoT seems emerging as a solution vehicle for data analytics on real-world scenarios from setting a room temperature setting to predicting a component failure of an aircraft. Compared with developing an application or deploying a cloud service, is an IoT solution unique? If so, how? How does a typical IoT solution architecture consist? And what are the essential components and how are they relevant to each other? How does the security play out? What are the best practices in formulating...

When shopping for a new data processing platform for IoT solutions, many development teams want to be able to test-drive options before making a choice. Yet when evaluating an IoT solution, it’s simply not feasible to do so at scale with physical devices. Building a sensor simulator is the next best choice; however, generating a realistic simulation at very high TPS with ease of configurability is a formidable challenge. When dealing with multiple application or transport protocols, you would be...

IoT is at the core or many Digital Transformation initiatives with the goal of re-inventing a company's business model. We all agree that collecting relevant IoT data will result in massive amounts of data needing to be stored. However, with the rapid development of IoT devices and ongoing business model transformation, we are not able to predict the volume and growth of IoT data. And with the lack of IoT history, traditional methods of IT and infrastructure planning based on the past do not app...
Internet-of-Things discussions can end up either going down the consumer gadget rabbit hole or focused on the sort of data logging that industrial manufacturers have been doing forever. However, in fact, companies today are already using IoT data both to optimize their operational technology and to improve the experience of customer interactions in novel ways. In his session at @ThingsExpo, Gordon Haff, Red Hat Technology Evangelist, shared examples from a wide range of industries – including en...
To get the most out of their data, successful companies are not focusing on queries and data lakes, they are actively integrating analytics into their operations with a data-first application development approach. Real-time adjustments to improve revenues, reduce costs, or mitigate risk rely on applications that minimize latency on a variety of data sources. Jack Norris reviews best practices to show how companies develop, deploy, and dynamically update these applications and how this data-first...
