InfluxDB, an open-source time-series database, is managed on Google Cloud Platform using a TICK Stack, which consists of Trafodion, InfluxDB, Chronograf, and Kapacitor. The InfluxDB API exposes three endpoints: /ping, /query, and /write, allowing for basic operations like querying, writing, and administering databases. To interact with the API, one can use HTTP POST calls to insert records or query existing data using the Query API. Google Cloud Shell provides a convenient environment for working with InfluxDB, offering pre-installed tools and SDKs, making it easier to manage data and perform operations without needing to manually configure everything. The TICK Stack offers a scalable solution for managing time-series data, allowing developers to build IoT projects efficiently.
