Getting Started with AWS IoT (Internet of Things)

Introducing AWS IoT

AWS IoT is a managed cloud platform that lets connected devices easily and securely interact with cloud applications and other devices. AWS IoT can support billions of devices and trillions of messages, and can process and route those messages to AWS endpoints and to other devices reliably and securely. With AWS IoT, your applications can keep track of and communicate with all your devices, all the time, even when they aren’t connected.
AWS IoT makes it easy to use AWS services like AWS Lambda, Amazon Kinesis, Amazon S3, Amazon Machine Learning, Amazon DynamoDB, Amazon CloudWatch, AWS CloudTrail etc  to build IoT applications that gather, process, analyze and act on data generated by connected devices, without having to manage any infrastructure.

Offerings under AWS IoT

AWS IoT provides a managed, multitenant service that enables communication between IoT devices, applications, and the backend. By virtue of being a managed service, IoT platform eases out several deployment and infrastructure monitoring issues.
Connectivity between devices and the AWS cloud. First, with AWS IoT you can communicate with connected devices securely, with low latency and with low overhead. The communication can scale to as many devices as you want.
Processing data sent from connected devices. Secondly, with AWS IoT you can continuously ingest, filter, transform, and route the data streamed from connected devices. You can take actions based on the data and route it for further processing and analytics.
Application interaction with connected devices. Finally, the AWS IoT service accelerates IoT application development. It serves as an easy to use interface for applications running in the cloud and on mobile devices to access data sent from connected devices, and send data and commands back to the devices.
 

How does AWS IoT function ?

Not only does connected devices connect to AWS IoT over over HTTPS, WebSockets, or secure MQTT, but the included Device Gateway allows secure, low-latency, low-overhead, bi-directional communication between connected devices and your cloud and mobile applications.
There is also a Device Registry where you can register and keep track of devices connected to AWS IoT, or devices that may connect in the future. Device Shadows in the AWS IoT service enable cloud and mobile applications to query data sent from devices and send commands to devices, using a simple REST API, while letting AWS IoT handle the underlying communication with the devices.
 The Rules Engine  enables continuous processing of data sent by connected devices. You can configure rules to filter and transform the data. You also configure rules to route the data to other AWS services such as DynamoDB, Kinesis, Lambda etc.
To simplify the development of code running on connected devices, AWS IoT provides open-source device SDKs for C, Node.js, and the Arduino Yún platform. AWS IoT has also partnered with hardware manufacturers to make the AWS IoT Device SDKs available on several IoT, embedded OS, and micro-controller platforms.
You can use AWS IoT regardless of your geographic location, as long as you have access to one of the above AWS regions.

10 Data Science Interview Questions You must be Acquainted With

Image
1. How would you create a taxonomy to identify key customer trends in unstructured data? The best way to approach this question is to mention that it is good to check with the business owner and understand their objectives before categorizing the data. Having done this, it is always good to follow an iterative approach by pulling new data samples and improving the model accordingly by validating it for accuracy by soliciting feedback from the stakeholders of the business. This helps ensure that your model is producing actionable results and improving over the time. 2 .  Python or R – Which one would you prefer for text analytics? The best possible answer for this would be Python because it has Pandas library that provides easy to use data structures and high performance data analysis tools. 3.  What are feature vectors? A feature vector is an n-dimensional vector of numerical features that represent some object. In machine learning, feature vectors are used to r

The enterprise architecture has made its way to prove that it supports the business architecture to a great extent. While designing the business, using TOGAF the modeling tool manly targets all aspects of Enterprise Architects. The language needs to be understood as well as the practical engagement is also of utmost importance. One can start with the entry level solution into the Archimate language. It also needs to be remembered that with the help of the EA, an outline can be drawn for the company. It may also include description such as, how the human can be utilized by assigning them to particular roles, further subdividing the organization into small unit and various locations. The structural part of an organization represented by the Archimate is business actors. According to the standard, business actor can be a human part, a specific department or simply any business unit. Here is a replica of a diagram how vertical organization reveals problem and the legitimate sol
