What does Thingsboard gateway does?
It is built on java
Connect to various front end field devices in a variety of formats
Provide a persistent layer to keep that data guaranteed

Gateway questions remain
is it a physical appliance?
Does it talk to devices through wifi?
Or is it an internet device?
Is it like a router?
What hardware is the gateway?
satya - 3/13/2018, 9:39:55 AM
OPC-UA
it is an optimized enhanced, made independent, Microsoft DCOM and SOAP like effort to have industrial devices talk to each other, perhaps over any network including tcp/ip.
satya - 3/13/2018, 9:52:54 AM
MQTT
Can run on top of tcp/ip networks
Client is very light, the one that connects to a server which is the broker. Many client libraries are available
Clients may sit behind ip routers like homes
An MQTT broker can sit anywhere reachable by tcp/ip
Broker has authentication protocols enabled
it has persistence
Broker is the central hub
Needs to be highly scalable
satya - 3/13/2018, 9:53:06 AM
It is a protocol on tcp/ip

So what is thingsboard gateway?
It is a java based software that sits on any server (like windows) like a web server on top of tcp/ip. It can be anywhere as long as the devices can reach it via MQTT (which itself can run on tcp/ip).

Difference between Thingsboard iot gateway and thingsboard server node
A thingsboard server only allows certain protocols like MQTT
The gateway will bridge the gap with connectivity to devices and a variety of protocols

How do IOT devices talk?
Many IoT devices can?t afford to embed third-party SDK. ThingsBoard provides quite simple API over common IoT protocols. You can choose any client-side library you like or use your own.
You can use MQTT (over SSL) or HTTPS protocols for transport encryption.
Each device has unique access token credentials that is used to setup connection. Credentials type is pluggable, so X.509 certificates support is coming soon.

So Kaa
Kaa enables data management for connected objects and your back-end infrastructure by providing the server and endpoint SDK components. The SDKs get embedded into your connected device and implement real-time bi-directional data exchange with the server. Kaa SDKs are capable of being integrated with virtually any type of connected device or microchip.
The Kaa server provides all the back-end functionality needed to operate even large-scale and mission-critical IoT solutions. It handles all the communication across connected objects, including data consistency and security, device interoperability, and failure-proof connectivity.
The Kaa server features well-established interfaces for integration with data management and analytics systems, as well as with your product-specific services. It acts as a foundation for your back-end system that you are free to expand and customize to meet the specific requirements of your product.

satya - 3/13/2018, 1:28:16 PM
How does Kaa store data
Some metadata is stored in an SQL database, but all of the endpoint-related data is stored in a NoSQL database. Kaa currently supports two options for NoSQL data storage: Cassandra and MongoDB. Kaa provides an abstraction layer for data storage, which means that you can develop and use plugins for other NoSQL databases.

satya - 3/13/2018, 1:30:00 PM
How can I connect my ZigBee or Bluetooth device to the cloud?
You can integrate the Kaa SDK with a hub that has an IP connection to the cloud, and a Zigbee coordinator and/or a Bluetooth controller. For example, this hub can be a Raspberry Pi board that is connected to your local WiFi network and has an XBee module. The hub would then use Kaa to represent the devices behind it.
Alternatively, an IP transport can be implemented on top of a non-IP connectivity layer. In this case, the Kaa SDK can be embedded into the actual endpoint device, and the hub would act as a bridge.

Few edge requirements as stated in that article
Connectivity and orchestration of various IoT data sources and technologies such as MQTT, CoaP or REST
Wiring together hardware devices, APIs and online services
Data Cleaning: Transformation, filtering, routing, aggregation, enrichment of data
Data Processing: Error handling, Re-Try, Re-Routing, Waiting, Resuming
Synchronous and asynchronous communication
Typically, real time processing
Visual coding, testing and debugging with flow editor, but also option respectively need to write source code and extend components using the open SDKs and APIs.
Deployed at the edge, either at a local IoT Gateway or directly on devices and sensors
