All Your Base Are Belong To Us

• Computers are all around us

• Computers on our desks

• Computers in our pockets

• Computers in our cars

• Computers in our washing machines

• Computers that we can swallow

Embedded Devices

• A computer that does not look like a computer can

be called: Embedded Device

• An Embedded Device connected to the Internet is an

Internet Of Things Device

IoT “device”

• An “IoT Device” does not exists

• You have IoT when you have Things (Devices) and

Internet

• A Solution that Integrates Devices and Internet-

Based Services is an IoT Product

Internet of Things

• IoT is not about devices connected to the Internet

• IoT is about devices using the Internet to

communicate and provide services

Data, data and more data

• Collecting data is easy

• Aggregate, process and understand data is complex

• Extracting relevant information from big data

collections is the key for a successful IoT solution

Telemetry

Information flowing

from a device to other

systems for conveying

status of device and

environment

Inquiries

Requests from devices

looking to gather

required information or

asking to initiate

activities

Commands

Commands from

other systems to a

device or a group of

devices to perform

specific activities

Notifications

Information flowing

from other systems

to a device/group for

conveying status

changes in the world

Challenges

MILAN november 28th/29th, 2014 – Valter Minute

• Asynchronous– decouple sender and receiver

• Patterns– Publish/Subscribe

– Request/Reply (with correlation)

• Message durability and devices availability– Temporal decoupling

• High rate traffic and high data throughput

• Big Data analysis and backend with its own pace– Load leveling

– Load balancing

• Reliability and QoS

• Scalability

Why Messaging?

– Queues

– Topics/Subscriptions

– Event Hubs

• Will be released as open source on

GitHub

Reykjavik

MILAN november 28th/29th, 2014 – Valter Minute

• Devices connect via open standard protocols

– Native support for AMQP 1.0 and HTTP

– MQTT, CoAP via adapters

– Sockets secured via TLS (or a lightweight variant)

– Custom protocol gateway needed for it

• Field Gateways
