Customer challenge

Hennessy Auto, a leading metro Atlanta used luxury car dealer, struggled with inefficient inventory management due to their outdated on-premises data infrastructure. This limited their ability to make data-driven decisions, potentially leading to stockouts or overstocking. The legacy system's scalability constraints, data silos, manual processes, and security vulnerabilities directly hindered their ability to optimize inventory levels for maximum profitability. Client partnered with ITTStar's data consultants to embark on a DevOps-driven transformation focused on building a modern cloud-based data platform. This initiative aimed to unify inventory-related data, streamline processes, enhance security, and provide real-time insights. The goal was to provide Client with the tools to efficiently manage inventory, reduce costs, and improve customer satisfaction through better vehicle availability.

Partner Solution

As an Advanced AWS Partner, our data lake solution leveraged a scalable architecture with zoned S3 buckets for structured, flexible storage. An event-driven approach using Lambda functions, SNS, and SQS ensured automatic processing and efficient resource usage. AWS Glue streamlined analytics with schema discovery and data cataloging, enabling easy Athena queries. Robust data transformations powered by Lambda functions and Glue jobs guaranteed reliable data preparation. A strong emphasis on security was evident in the use of SSM Parameter Store and Secrets Manager. To ensure a seamless DevOps experience, we prioritized automation for bucket management, robust CI/CD and testing for Lambda functions, monitoring of Glue resources, IaC for transformations, and automated secret rotation within pipelines.

Why AWS?

AWS provides secure, reliable, scalable, and affordable cloud computing services. To leverage scalability, AWS can easily manage increasing workloads by allocating resources based on demand. Offering products ranging from hosting data in the cloud with S3 to logical isolation with Amazon VPC. AWS Lambda is designed to let you run your code without setting up and managing servers. AWS SQS (fully managed message queue) for communicating with Lambda based on events in S3.

New data comes into the input bucket in S3. Amazon S3 publishes events to an SQS queue and transfers data to the queue. Queued data is retrieved using AWS Lambda. Data is processed by Lambda and returned to the S3 output bucket. The same process is used and data is consumed from a local MS SQL Server.
