The OSIsoft Open Edge Module is an open-source platform for the Internet of Things (IoT) that integrates with fog computing, enabling efficient data management and processing between edge devices and the cloud. It features a microservices architecture addressing issues such as connectivity, security, and data quality, allowing for unattended operation even in unreliable environments. Key functionalities include data collection, storage, and analytics capabilities, along with robust management interfaces for scalability and resilience.

Introducing Fog Computing
“An architecture that uses one or more collaborative end-user clients or
near-user edge devices to carry out a substantial amount of storage,
communication, control, configuration, measurement and management.”
https://en.wikipedia.org/wiki/Fog_computing

Introducing Fog Computing
“A decentralized computing infrastructure in which data, compute,
storage and applications are distributed in the most logical, efficient
place between the data source and the cloud.”

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.
