In the next chapters (Chapter 9, Understanding Industrial OEM Platforms, Chapter 10, Implementing a Cloud Industrial IoT Solution with AWS, Chapter 11, Implementing a Cloud Industrial IoT Solution with Google Cloud and Chapter 12, Performing a Practical Industrial IoT Solution with Azure), we will look at some of the solutions proposed by AWS, Azure, Google, and Predix for TSDB. Generally speaking, these solutions support TSDBs based on NoSQL and SQL databases (Apache Cassandra, SQL Server, and DynamoDB) and extend the schema with the API.
