Architecting a Point of Sales application for the Edge

 Edge computing is a computing architecture that moves data processing and storage from centralized systems to the edge of the network. In a Point of Sales (POS) system, this can bring several advantages, such as:

Latency reduction: By processing data at the edge, latency is reduced, making transactions faster and more efficient.

Improved reliability: With edge computing, the system can operate even if there is a failure in the central system, making the system more reliable.

Increased security: By processing data at the edge, the risk of data breaches is reduced as the data is not transmitted to a centralized location.

Offline operation: In the event of a network failure, edge computing can allow the POS system to continue operating, reducing downtime and providing a better customer experience.

Scalability: Edge computing makes it easier to scale the system as needed, making it more flexible to meet changing business needs.

When considering edge computing for a POS system, some key factors to consider include:

Network connectivity: The system must be able to connect to the edge devices, such as mobile devices, payment terminals, and sensors.

Code and data deployments: A mechanism is needed to deploy the latest code features and upgrades as well as the core data from the 

Data processing: The system must be able to process large amounts of data in real-time at the edge.

Data storage: The system must be able to store data at the edge, either locally or in the cloud.

Security: The system must be secure, protecting sensitive customer data and ensuring that transactions are protected from cyber-attacks.

Integration with existing systems: The system must be able to integrate with existing systems, such as inventory management and customer relationship management
