This document discusses the pros and cons of building an in-house data analytics platform versus using cloud-based services. It notes that in startups it is generally better not to build your own platform and instead use cloud services from AWS, Google, or Treasure Data. However, the options have expanded in recent years to include on-premise or cloud-based platforms from vendors like Cloudera, Hortonworks, or cloud services from various providers. The document does not make a definitive conclusion, but discusses factors to consider around distributed processing, data management, process management, platform management, visualization, and connecting different data sources.
