Great Article Jim! SIAM is even more critical for IoT/IoE. IoT introduces:

· Multiple sensor types, many with no unique IP address to track (often getaways are used for sensor identifications).
· Multiple access protocols (e.g. Zigbee, MQTT, CoAP, XMPP, SIP just to name a few). It’s unlikely to see IoT protocol conversion any time soon. This is due to the fact that different protocols are needed to address different IoT requirements. For example, CoAP (Constrained Application Protocol) over UDP is primarily, a one-to-one protocol for transferring state information between client and server. It is used for resource constrained, low-power sensors and devices connected via lossy networks, especially when there is a high number of sensors and devices within the network. On the other hand, MQTT over TCP is a many-to-many communication protocol for passing messages between multiple clients through a central broker.
· Multiple IoT Getaways addressing multiple vertical needs. Cisco plays an import role is this area.
· Multiple verticals such as Industrial, Smart cities / Smart buildings, eHealth, Agriculture, etc.

Hence,
· Managing multiple Suppliers of the various components (e.g. sensor suppliers, component suppliers, network management suppliers, embedded management software suppliers) for IoT solutions/services and integrating them to provide a single business-facing view is essential.
· Managing multiple Partners for IoT services. Eco-system partners work with suppliers and enterprises/customers to deliver, deploy, integrate, monitor, and/or manage IoT services. This are is extremely important for Cisco where the majority of deals include ecosystem patterns. Generally, IoT suppliers operate on the Physical Layer while IoT Partners operate at the application layer of IoT stacks.

With up to the minute monitoring and management requirements in IoT, no solution can practically operate without seamlessly integrating interdependent services from various internal and external service providers into end-to-end services in order to meet business requirements. SIAM is great overall framework for address the above 1-5 IoT requirements for Service Integration and Management. Managing multiple suppliers and partners to support IoT end-to-end services and integrating them to provide a single business-facing IT organization is perhaps the most essential SIAM value.

Unlike ITIL, which is implemented in line with proprietary models developed by large IT providers, SIAM is aimed at delivering a framework and establishing body of knowledge. It targets integrating interdependent services from internal and external service providers into global services in order to meet business requirements
