Guidance for Traditional POS Checkout on AWS

Overview

This Guidance demonstrates how retailers can set up a point of sale (POS) system in the AWS Cloud. Data captured by in-store card readers and POS terminals is securely transmitted to backend applications for processing and settlement. Key business processes such as checkout, order processing, inventory management, and back office functions are all integrated from the corporate data center to the Cloud. The security and confidentiality of the captured data is ensured through monitoring, security, and protection measures.  

How it works

This diagram shows how to build a cloud-based point of sale (POS) system for retailers and merchants on AWS.

Well-Architected Pillars

The architecture diagram above is an example of a Solution created with Well-Architected best practices in mind. To be fully Well-Architected, you should follow as many Well-Architected best practices as possible.

Outposts , Lambda , and Amazon ECS Anywhere provide low-latency edge capabilities for the retail store, ensuring a superior customer experience, quickly.

Read the Operational Excellence whitepaper 

Both Direct Connect and Site-to-Site VPN provide secure connections between the retail store and the AWS Cloud. And, by using IAM and AWS KMS for securing and encrypting the data, you can continually adjust permissions on the journey to least privilege.

DynamoDB , Amazon S3 , and Aurora are used as core components of this Guidance to power performance-intensive workloads. 

Read the Performance Efficiency whitepaper 

Serverless services such as Lambda , Step Functions , and EventBridge are used extensively throughout this Guidance to help you build and operate cost-aware workloads that achieve business outcomes, while minimizing costs. Maximizing your return on this investment. 

Read the Cost Optimization whitepaper 

AWS services enable you to maximize the benefits of your resources while reducing your carbon footprint. The services selected in this Guidance help you scale both up and down according to demand. The serverless components also automate the process of infrastructure management, reducing energy while gaining efficiencies.
