1 Lesson 5 Nimbits 1

2 Cloud IoT cloud-based Service Using Server at the Edges A server can be deployed at the edges (device nodes) which communicates the feeds to the cloud service. The server also provisions for the generation and communication of alerts, triggers and feeds to the cloud service Server can be mirror server for the cloud server Chapter-6 L04: "Internet of Things ", Raj Kamal, 2

3 Cloud IoT cloud-based Service To User Applications and Services User applications or services use the collected data at the cloud infrastructure Chapter-6 L04: "Internet of Things ", Raj Kamal, 3

5 Nimbits Enables IoT on an open source distributed cloud Nimbits cloud PaaS deploys an instance of Nimbits Server at the device nodes Functions as M2M system data store, data collector and logger and access to historical data. Architecture a cloud-based Google App Engine 5

6 Nimbits Server A class hierarchy com.nimbits.server.system.serverinfo of the java.lang.object 6

7 Nimbits Features Edge computing locally on embedded systems, built up of local applications. Runs the rules and pushes important data up to the cloud running when connected over Internet and An instance of Nimbits Server hosts at the device nodes which is when enabled 7

8 Rule Engine For connecting sensors, persons and software to the cloud and one another Rules can be for calculations, statistics, alerts, xmpp messages, push notifications and more. 8

9 Nimbits Support Multiple programming languages, including Arduino, new Arduino Library Push functions from Arduino cloud, JavaScript, HTML or the Nimbits.io Java library. Nimbits server functions as a backend platform 9

10 Nimbits Support Data point can relay data between the software systems, or hardware devices such as Arduino, using the cloud as a backend. An Open Source Java Library nimbits.io enables easy development of JAVA, Web and Android solutions (Nimbits data, alerts, messages on mobile). 10

11 Nimbits Features Provides a data logging service and access and stores the historical data points and data objects. Storage in any format that can be serialised into a string, for example, JSON or XML. Filters the noise and important changes sent to another larger central instance. 11

12 Nimbits Processes a specific type of data and can store it. Time- or geo-stamping of the data. Nimbits clients provide over Internet, data collection in real-time, charts, chart and graphical plots of collected data and data entry. 12

13 Nimbits Features Data visualisation for data of connected sensors to IoT devices Supports the alerts subscription, generation and sending in real time over Internet Creates streams of data objects, and stores them in a data point series 13

14 Nimbits Features Data accessibility and monitoring from anywhere, and is used to shape the behaviour of connected devices and software Supports the mbed, Arduino, Raspberry Pi based and other hardware platform based IoT devices. 14

15 Nimbits Features Web service APIs are easy to implement on device hardware acting as clients to Nimbits web services, and connect to the web service and send data. Deploys software on Google App Engine, any J2EE server on Amazon EC2 or on a Raspberry Pi. 15

16 Data Generation and Store Architecture A NimbitsServerL which deploys at each device Node The server at device node is an instance of the NimbitsSeverS at the cloud Each NimbitsServerL of the device node generates the calculation objects for device nodes 16

17 Data Generation and Architecture Each node also hosts an XMPPServerL, an instance of the XMPPSeverC at the cloud. XMPPServerL deploys at each device node and generates the data feed channels for the XMPP messages and alerts.each XMPPServerL sends feeds to XMPPSeverC. 17

19 Data Point and its Child Points A data point means a collected value of a sensor in a group of sensors. Data points organise the data in a number of ways. For example, points can have child points. Child points mean sub-points, for example, if light level is a data point then light on or off is a child point and light level above or below the threshold can be another child point.) 19

20 Folders and Subfolders Points can be in the folders The folders can go as deep as like in a tree. Tree means a folder having several subfolders, a subfolder having several subfolders, till the leaf sub Folder. 20

21 Subscription data feed A subscription data feed is a special point for each user that logs system messages, events, alerts from other points which are subscribed by a service and more. 21

22 Data Channels A user can create a data-feed channel which shows the system events and messages that also shows data alerts which are subscribed to show up in the feed 22

23 Data Channels The user subscribing to the data point of other users also, and configure the subscription(s) to send messages to the feed The user observing the idle, high or low alerts here in real time. The user data feed is just another Nimbits data point. 23

24 Nimbits Advanced Features H2 database engine H2, a Java SQL database. APIs in pure Java and Very fast, open source, JDBC API 24

25 Nimbits Advanced Features Encrypted database ODBC driver Full text search Multi version concurrency Browser based console application Small footprint 25

26 Nimbits Advanced Features Security features Breakthrough performance Alerts Jabbing 26

27 Nimbits Subscriptions Features A user creating many subscriptions for a single point. May subscribe to one of the points, other user, or anyone s public point to get the alerts Alerts when the point goes into an alarm state, or receives new data. Alarm state, reaching preset value. 27

28 Summary Points Calculation Objects Nimbits Advanced Features 28

29 Summary We learnt Nimbits Cloud PaaS service deploys an instance of Nimbits server at Arduino, Raspberry Pi or other IoT sensor nodes platforms that provides for real-time data collection, store at an H2 Database. 29

30 Summary We learnt Edge computing Nimbits data, alerts, messages, application programmed to get alerts (XMPP, Twitter, or other) Rule engine Alerts and feeds on subscriptions Triggers and requests. 30

31 Summary We learnt Data visualisation Analytics Calculation objects Summary points 31
