Case Study: LG Electronics achieves 80% development cost savings and a scalable, serverless IoT platform with Amazon Web Services

LG Electronics - Customer Case Study

LG Electronics launched its ThinQ brand to connect AI-enabled smart TVs and appliances (more than 70 million TVs and 5 million appliances sold) but rapid growth in Wi‑Fi–enabled devices strained its on‑premises servers and made it hard to secure development and operations resources. The company needed a scalable, secure, and easy‑to‑manage IoT platform to maintain reliable device connectivity and support expanding smart services.

LG migrated its IoT platform to AWS, adopting AWS IoT Core, AWS Lambda, Amazon DynamoDB, Amazon ElastiCache, X.509 authentication, and the Device Shadow service to enable continuous connectivity, cached device state, and a serverless architecture. The move cut development costs by 80%, reduced operational overhead, let developers focus on business logic, and supported new services like chatbots, air‑quality monitoring, and energy solutions while ongoing collaboration with AWS architects improved infrastructure reliability.
