7IIoT architectures are converging toward Fog Computing to address their Connectivity, Latency, Throughput, Determinism, Security and Cost challenges

From Cloud to fog computing

Horizontal, system-level architecture that distributes computing, storage, control and networking functions closer to the users along a cloud-to-thing continuum

DDS has applicability across the 6 IT levels

For the SCADA and the life-cycle, DDS’ applicability depends on the constraints of the device

DDS-XRCE will bring connectivity to extremely small devices, i.e. at most 100KB of RAM

Vortex Fog is an elastic and fault-tolerant software appliance that transparently draws a boundary around a subsystem to control and adapt QoS and transports, e.g. from UDP/IP m-casts to TCP/IP, and information flow

Vortex Fog also minimises discovery traffic while maintaining interoperability and dynamic matching

Vortex Cloud is a elastic, fault-tolerant, multi-data-centre, and IaaS independent “Cloud Messaging” implementation of DDS

Vortex Cloud be used to transparently integrate systems that can’t directly talk with each other because of NAT/FIREWALLS

It can be used for as a very high performance Private Cloud Messaging as an alternative to Amazon SMS, SQS, or Azure Service Bus
