Vivint, America's largest smart home solutions company, built a flexible smart home platform using MongoDB that could scale to 500m data points per day on geo-distributed clusters. The platform, called Vivint Sky, was designed and built in under a year to meet the company's hardware and sales cycle requirements. It integrates with various smart devices from multiple providers and allows users to access and control them via a single interface. The MongoDB deployment has grown to 10 shards on 50 nodes across multiple geographies, resulting in improved performance and reduced operational tasks for the database administrator team.
