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.

MQTT Broker

Search for: MQTT Broker

MQTT essentials

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

Here is how to install on windows

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

Search for: 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

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.

Here is overview of 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.

Here is Kaa faq

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.

Spring Framework.

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.
