Agenda
Aspects of IoT development
Business & Technical Concerns (or Functional & Non
Functional Requirements)
Why Java?
Using Standards – pick your flavor!
IRL
Q&A

ASPECTS OF IOT DEVELOPMENT
Oh so many things to consider!

IoT Development…
Is not just connecting things
Has a lot of constraints
Has many horizontal aspects and as many vertical
aspects

On connecting things
The buzz of IoT is connecting things
Does everything needs to be connected?
The implications of connectivity

It’s here and there
We can talk about these concerns both in embedded
and cloud development
We’re going to focus more on embedded

So many constraints!
Hardware constraints
Software constraints
Protocol constraints
Real life considerations

Aspects deep and wide
Business considerations
• What process are we replacing, enhancing or
creating?
• Who’s being impacted, equipment and people
wise?
Technical considerations
• Even very different verticals have the same
technical requirements – and this lets us leverage
standards

BUSINESS & TECHNICAL CONCERNS (OR
FUNCTIONAL & NON FUNCTIONAL REQUIREMENTS)
What do you need, commander?

It starts very simple
”Just need this value in this system”
”Can’t you just connect a cable and read it?”
”Just put a chip in there and it’ll work”
”But it’s just a modem”

But it gets complicated
Explicit concerns
And ones they don’t even think about

It gets down to
• Safety
• Security, Trust & Privacy
• Resilience
• Integrability, Interoperability and Composability
• Connectivity
• Data Management
• Analytics and Advanced Data Processing
• Device Management

WHY JAVA?
would you like a cup of java with that, sir?

Java…
…is a programming language and computing platform
first released by Sun Microsystems in 1995.
…has a vibrant ecosystem where open source plays a
major role
…virtual machine allows true ”write once, compile
once and run anywhere” for embedded and server
environments

USING STANDARDS – PICK YOUR FLAVOR!
Oh so many choices!

Standards address common issues
Every major concern in our bucket list has at least one
standard to address it
But sometimes too many standards do get in the way
Standards and open source go very well together

Data Management
• Query, Publish and Subscribe
• Storage, Persistence and Retrieval
• Integration
• Description and Presence
• Rights Management

Security, Trust & Privacy
• Endpoint security
• Communication security between the endpoints
• Data distribution and secure storage
• Management and monitoring security of both the
endpoints and the communication mechanism

Connectivity
• Communication Transport
• Get data there
• Connectivity Framework
• How data is structured and used

Integrability, Interoperability and
Composability
• Integrability
• Interoperability
• Composability

Device Management
• Day-to-day operations (who’s not online and why)
• Firmware & configuration management
• Billing
• Non-functional aspects

IRL (IN REAL LIFE)
What would you choose?

A Smart Freezer
• ”Simple” business concept
• Monitor temperature to avoid product loss
• ”Since we are doing this, why not…”
• Monitor stock level
• Check if others are using our freezer for something else
• Server and embedded development

Addressing the concerns – Connectivity &
Security
• Use JCA (Java Crytography Architecture) for security
concerns
• Or, alternatively BouncyCastle framework
• JavaCard/PKCS11 helps with authentication and
cryptography
• Standard protocols for IoT communication
• HTTPS (TLS/SSL) if you can afford
• MQTT
• CoAP

Addressing the concerns – Data Integration
• Java has plenty of standards for data parsing and
representation
• JSR 363 for measurements
• JSR 353 for JSON-P
• JSR 339 for JAX-RS (REST)
• JSR 343 for Messaging (JMS 2.0)
• You can use an MQ that exposes MQTT to the devices and JMS
to your servers
• Using these standards in a Java EE environment will lead to
a very efficient development

Addressing the concerns – Integrability
• Extensive Java EE standards for REST and SOAP
WebServices
• JSR 363 helps with interoperability between diverse
systems

It gets more complicated...
• When thinking of expansion, it does get more complicated
as there are many different aspects to consider
• Device management
• Multiple WANs
• Multiple legacy protocols
• There are plenty of options that encapsulate (some) of
these concerns, for a cost (or not)

Going the open source route…
• iot.Eclipse.org has a ever increasing (20+) suite of tools
and frameworks for IoT that helps to address some
concerns we discussed
• You can get professional support on top of them
• Kura (OSGi for services gateways)
• Paho (open-source implementations of open and standard
messaging protocols)
• For server side, we get a LOT of options (just look at your
session catalog )

… Or closed systems
• Major IT vendors have something to offer in IoT now
• For device development
• Standard framework for development
• Tight integration with backend system
• And server side
• Device management
• Message Routing
• Analytics and Processing

Major IoT offerings
• Oracle IoT CS
• IBM BlueMix
• GE Predix
• Microsoft Azure IoT
• Amazon AWS IoT
• PTC ThingWorx

In the end…
• There are plenty of options to match plenty of requirements
• Each project is a project, and you’ll be re-evaluating
requirements for each of them
• It pays to have a broad knowledge of what’s available and
do a quick survey of their strengths
• Standardized solutions will always be the ones with better
support and odds of being the best tool
