Revolutionizing Point-of-Sale Operations Through AWS Cloud Migration

The client is a multi-location retail business that relied on a legacy POS system hosted on on-premise servers. With rising operational demands and the need for scalability, the client aimed to modernize their technology landscape. They sought expert cloud migration consulting services to re-architect their POS system using AWS Cloud for better performance, flexibility, and security. The client’s existing POS system for small business struggled with uptime issues and lacked seamless integration across retail outlets. To modernize their retail POS system, they adopted AWS cloud-native services, enabling real-time data access, centralized control, and scalability. This upgrade in POS system software ensured their small business POS system could meet growing operational demands and customer expectations.

Problem Statement

Frequent outages in the point of sale system during peak hours caused customer dissatisfaction and revenue loss.
Lack of real-time data sync across point of sale outlets led to inventory discrepancies and inconsistent reports.
High capital expenditure on hardware upgrades and maintenance raised the point of sale system operational costs.
Security gaps due to lack of compliance and modern encryption risked point of sale system data safety.

Solution Approach

Assessed the legacy POS system, identified key risks, and designed a phased, low-risk cloud migration strategy.
Transformed the monolithic POS into microservices using ECS Fargate and Lambda for better scalability and agility.
Set up real-time data sync with AWS Lambda + DynamoDB Streams, improving consistency across all outlets.
Implemented CI/CD with CodePipeline and strengthened security with KMS encryption, IAM, and VPC isolation.
