Zillow has become the nemesis of real estate agents in the U.S. after former Microsoft executives and Expedia founders developed the platform to offer consumers housing prices and analysis previously reserved for professionals.
The free services Zillow offers include allowing consumers to check the past, present, and estimated future values of homes.
Zillow's "Zestimate," for example, uses machine learning to power its secret algorithm that helps to predict the future value of properties.
The company has largely bolstered its data analysis capabilities by acquiring several brands, such as Trulia, HotPads, StreetEasy, Naked Apartments, Mortech, dotloop, and Retsly.
Zillow's platform is based on Apache Spark and it relies on AWS S3 for cloud services and AWS Redshift and Presto for data storage. For historical data analysis, Zillow uses Presto.
