Issues for Data in IoT, IIoT and Fog Computing

• Connectivity• Intermittent networks• Network windows• Low bandwidth

• Security• Authentication (single/dual)• Encryption (at rest and in motion)• Attestation

• Operating Environment• Temperatures• Dust, water, humidity, acidity• Power sources

• Capital expenditure and Operating Costs

• Latency / Response Time• Predictable response time• Minimal or no network latency

• Data Quantity• Millions or billions of sensors• Billions or trillions of data points

• Data Quality• Errors and malfunctions• False positives/negatives

• Compatibility and Fragmentation• Multiple and non interoperable

stacks, platforms, frameworks

What If...

… you can use the same platform for server development and deployment on any layer, managing and consuming your data where is needed?

Introducing the Open Edge Module

The Open Edge Module is a platform for the Internet of Things and an

essential component in Fog Computing.

It uses a modular microservices architecture including sensor data

collection, storage, processing and forwarding to historians, Enterprise

systems and Cloud-based services.

The Open Edge Module can run in highly available, stand alone,

unattended environments that assume unreliable network connectivity.

Micro-Services Architecture

• The module is more modules• It is a number Micro-services• Co-operate to provide the Open Edge Service• Micro-services allow

• Distribution• Scale-out/Scale-up• Resilience• Best language/deployment choices

15

Core Micro-Service

• Centre of the Open Edge universe• Provides REST API• Provides system level management

• Schedules activity

16

Southbound Interface

• Traffic to/from actuators & sensors• Multiple device interfaces• Many different protocols• Push mode v’s Pull mode devices

• Southbound micro-service plugin infrastructure• Multiple southbound micro-services

17

• Hides protocol, push/pull mode details• Moves sensor data to buffer storage• Pushes updates/management requests to

devices

Northbound Interface

• Path to the cloud/analytics

system

• Drains buffered sensor readings

• Transforms to analytics store

• Manages connectivity &

bandwidth

Storage Micro-Service

• Persists local configuration data

• Buffers sensor data

• Buffers management requests

• Plugin storage interfaces

• Configuration data in tabular store

• Sensor data in time series store

21

Open Edge Module Security

● Pluggable authentication

● Central certificate

management

● Protocol specific encryption

22

Application Interfaces

• Applications access buffered data

• Perform analysis at the edge

• Data accessible via REST API

• IN/OUT Communicator mimics traditional

data stores

23

Open Edge Module Management

• Millions to Billions of nodes• Really don’t want to manage these• Must run unattended

• Provision Centrally• Manage configuration changes centrally• Update centrally
