How To Developers

IBM Cloudant is a cloud based database product of the

non-relational distributed variety.

Using the Node-RED editor, the overall flow of the process

can be programmed and visualised for any type of service and

process. Node-RED is a flow based integrated development

tool created by IBM so that objects and their connections can

be set up without complex programming. Once the connections

are created with the IoT app and weather service, the different

channels including input, weather services, and transformation

of temperature format can be set in Node-RED. After the

successful deployment and launch of the service, the output

will be visible in the user panel. The conditions related to

different categories of weather (cloudy, sunny, rainy, humid,

etc) can be specified using the Node-RED editor.

Creating an app for vehicles and to

remotely monitor drivers

By using another IoT application, the multi-dimensional

behaviour of vehicle drivers can be analysed remotely using

IBM Bluemix on the Watson IoT platform.

The remote analytics of the weather, including temperature,

humidity and other parameters can be received by travellers,

and they can take the appropriate precautions.

First, a new IBM ID needs to be created on https://

console.bluemix.net/. IBM Bluemix provides users a

30-day trial, without need for credit card authentication.

Most other cloud services ask for international credit

card authentication. Users of IBM Bluemix, on the other

hand, can create, program and use the services with just

a unique e-mail ID.

After creating an account and logging in to the

Bluemix panel, there are many cloud based services

which can be programmed for real-time use. IBM

Bluemix is a hybrid cloud that delivers many types of

cloud applications including infrastructure, containers,

VMWare, network management, storage, the Internet of

Things, data analytics, high performance computation,

mobile applications and Web apps.

To create a weather notification app, just search

the IBM Bluemix catalogue for the Boilerplates based

Internet of Things.

The name of the new cloud app can be mentioned. The

other values and parameters can be set as default, as we are

working on a free trial account. Once the Cloud Foundry is

created, the next step is to connect this app with the Weather

Services in IBM Bluemix. Search for Weather Company

Data and IBM Bluemix will display the appropriate option.

Using Weather Company Data, live temperature and

weather parameters can be fetched effectively.

The newly created app will be visible in the

dashboard of IBM Bluemix and, automatically, a

Cloudant database will be created here. This database

will be used to store and process the data in JSON format.
