Why IOT on Cloud?
• Massive data ingest from millions of devices and connections! – RFID in malls.
• Its a system of record while simultaneously providing real-time analytics! – Cancer patterns.
• Respond to and integrate with familiar eco-systems! – OSS / BSS, Dashboards, etc.
• Allow for online scaling and online operations! – Growth of devices market. Loosely

Message Broker Rules Engine Thing Registry Device Gateway Security and Identity
Secured mechanism for Things and IOT
applications to publish and receive messages from each
other.
MQTT protocol for push and subscribe.
Message processing and integration
platform.
SQL to select data from message
payloads, process, send to other
Services.
It’s a Device Registry.
Which Device is registered with
which Thing. Organizes resources
associated with each Thing.
Enables Devices to Securely
communicate to Things and vice
versa.
Safely place credentials of IOT, IOT applications outside the IOT
platform.
Tightly integrated with 1, 2, 3 and 4.
