Need for IoT Systems Management 

IoT systems have complex software, hardware (sensors, actuators), network resources, data collection, analysis services, communication protocols, and user interfaces.

 The need for managing IoT systems are:

1.   Automating Configuration:

• ·         System management interfaces provide predicate and easy-to-use management capability to automation system configuration when a system consists of multiple devices or nodes.
• ·         Ensures all devices have the same configuration and variations or errors due to manual configurations are avoided.

 2.   Monitoring Operational & Statistical Data:

• ·         Operational data:- the system's operating parameters that are collected by the system at runtime.
• ·         Statistical data:- system performance (e.g. CPU and memory usage) data for fault diagnosis or prognosis (forecasting).

 3.   Improved Reliability:

• ·         By validating the system configurations before use.

 4.   System-Wide Configuration:

• ·         IoT systems consist of multiple devices or nodes, which have wide system configurations for the correct functioning.
• ·         Each device is configured separately (either manual or automated).
• ·         Used in system faults or undesirable outcomes.
• ·       Ensures that the configuration changes are either applied to all devices or to none.
• ·         In the failure, the configuration changes are rolled back.

 5.   Multiple System Configurations:

• ·         Some systems have multiple valid configurations according to different times or in certain conditions.

6.   Retrieving & Reusing Configurations:

• ·         Help in reusing the configurations for other devices of the same type.
• ·     Ensure that when a new device is added, the same configuration is applied.     
•      The management system can retrieve the current configuration from a device and apply the same to the new devices.
