We all have been hearing the term Data Science and Data Scientist occupation become more popular these days. I thought of sharing some light into this specific area of science, that may seem interesting for rightly skilled readers of my blog. 

Data Science is one of the hottest topics on the Computer and Internet  nowadays. People/Corporations have gathered data from applications and systems/devices until today and now is the time to analyze them. The world wide adoption of Internet of Things has also added more scope analyzing and operating on the huge data being accumulated from these devices near real-time.

As per the standard Wikipedia definition goes Data science, also known as data-driven science, is an interdisciplinary field about scientific methods, processes and systems to extract knowledge or insights from data in various forms, either structured or unstructured, similar to data mining.”.

Data Science requires the following skillset:

  • Hacking Skills
  • Mathematics and Statistical Knowledge
  • Substantive Scientific Expertise

Data Science Process:

Data Science process involves collecting row data, processing data, cleaning data, data analysis using models/algorithms and visualizes them for presentational approaches.  This process is explained through a visual diagram from Wikipedia.

Who are Data Scientist?

Data scientists use their data and analytical ability to find and interpret rich data sources; manage large amounts of data despite hardware, software, and bandwidth constraints; merge data sources; ensure consistency of datasets; create visualizations to aid in understanding data; build mathematical models using the data; and present and communicate the data insights/findings.

They are often expected to produce answers in days rather than months, work by exploratory analysis and rapid iteration, and to produce and present results with dashboards (displays of current values) rather than papers/reports, as statisticians normally do.

Importance of Data Science and Data Scientist:

“This hot new field promises to revolutionize industries from business to government, health care to academia.”

The New York Times

Data Scientist is the sexiest job in the 21st century as per Harward Business Review.

McKinsey & Company projecting a global excess demand of 1.5 million new data scientists.

What are the skills required for a Data Scientist, let me share you a visualization through a Brain dump.

I thought of sharing an image to take you through the essential skill requirements for a Modern Data Scientist.

So what are you waiting for?, if you are rightly skilled get yourselves an Data Science Course.

Introducing Azure IoT Edge

During Build! 2017 Microsoft has announced the availability of Azure IoT Edge, which would bring in some of the cloud capabilities to edge devices/networks within your Enterprise. This would enable industrial devices to utilize the capabilities of IoT in Azure within their constrained resources . 

With this Microsoft now makes it easier for developers to move some of their computing needs to these devices.  Edge devices are mostly having small foot print based to high end machines within your company network.

The essential capabilities to be supported by Azure IoT edge  include:

  • Perform Edge Analytics (a cut down version of Azure Stream Analytics)- Instead of doing analytics in cloud developer/implementer can move the basic cloud data processing and analytical capabilities to Edge Device. Run your machine learning algorithms in Edge device and take predictive analytics steps.
  • Perform Artificial Intelligence processing at edge device itself. Availability of Microsoft Cognitive Service on edge device would bring in whole lot of automation capabilities. Imagine Alexa/Siri working without internet connection, it should be able to provide you reminders etc.
  • Perform RealTime Decision making locally based on predefined rules.
  • Reduce bandwidth costs
  • Connect to other Edge devices and legacy devices within the constrained/corporate network.
  • Deploy IoT solutions to Edge Device from Cloud and provide updates as needed.
  • Operate offline without the need of real-time internet connectivity or intermittent connectivity. Doesn’t have to rely on Cloud to provide commands for processing, can do offline data capture and processing of information from other devices connected and take decisions without the need to rely on a connected cloud service.

Azure IoT Edge enables seamless deployment of cloud services such as:

IoT Jargons – Identity of Things (IDoT)

The Identity of Things (IDoT) is an area involves assigning universal unique identifiers (UUID) with associated metadata to devices and objects (things), to identify, connect and communicate effectively with other machines over the internet or within constrained local network.

The metadata included with the UUID characterizes the identity of an endpoint. Identity is an essential part of the Internet of Things (IoT), in which nearly anything conceivable can be tended to and organized for exchange of information on the web. In this specific cases, a thing can be anything – including both physical and sensible articles – that has a specific own identifier and the capacity to exchange information over a network.

Addressability and Reachability makes it possible for things/devices to be targeted and found. To make it addressable for  the Internet of Things, a thing must be globally uniquely identifiable(no other thing with same identity).

To make communication among things effective and secure, following are some of the essential considerations for identities of things:

  • Maintaining a Lifecycle:  IoT Devices should be capable of maintain a lifecyle depending on the use and duration of sustainability of the device. Hence IDoT should be capable of maintaining a history of changes happening to the device over its lifespan.
  • Maintaining Relationships:Identify also should provide a basic necessity to relate the device to other devices in the context as well as
  • Context-awareness: Identity and access management (IAM) for IoT entities should be context aware and grant access only limited to a specific context as required. This would avoid exploitation of devices incase of any cyber attack. 
  • Adequate Authentication: provide means of securely authenticating IoT identities.  This would ensure only authenticated entities can gain access to the IoT device.

All these essential features should help in obtaining a unique naming standards for IoT devices  or projects in your organization.
