Scorpio broker is a reference implementation of **NGSI-LD standard** specifications that are compliant to **ETSI standards**. Basically Scorpio broker is a core component of **FiWARE/IoT** platform wherein IoT data-driven by dynamic context is collected, processed, notified & stored/ingested with different application usage perspectives.
Scorpio broker also provides an implementation of REST API endpoints for various data context operations that conform to **NGSI-LD API** specification.
Scorpio broker allows you to collect, process, notify and store the IoT data with dynamic context with the use of linked data concepts.
It makes use of the **microservice-based architecture** build with the help of **spring boot**, which has its own advantages over the existing IoT brokers such as scalability, cross-technology integration, etc.

Scorpio Broker based on NGSI-LD offers a unique feature of Link data context that provides self-contained (or referenced) **dynamic schema definition** (i.e. the context) for contained data in each message/entity.
Thus allows the Scorpio Broker core processing to still remain unified even it gets dynamic context-driven data as its input from different types of data sources coupled(or designed for) with different schemas. 

Key advantages of Scorpio Broker over other brokers:

- Uses micro-service architecture which enhances the performance drastically.

- The Scorpio Broker architecture is designed & implemented as a scalable, highly available, and load balanced.

- Use of Ld which gives us the leverage of dynamic context.

- Usage of Kafka, allowing us the robust pub-sub service with the facility of scaling with no downtime.

- It provides fail-over resiliency.

- It provides load balancing to distribute the load on distributed infrastructure.

- It is modular enough to offer low coupling and high cohesion by design.

- It offers different storage integration without changing the application logic time and again.
