Choosing a machine type

When creating a Cloud SQL instance, the type of machine used determines many aspects of performance. The number of vCPU cores determines the instance's maximum storage capacity, network throughput, and maximum number of concurrent connections. The machine's memory size plays a large role in query performance, as more data can be stored in memory.

Any of the db-n1 family of machines can be used. Similar to Compute Engine machine types, this includes standard machine configurations, such as the default db-n1-standard-1 configuration and high-memory machines, such as db-n1-highmem-2. As stated before, shared-core machines do not fall under Google's Cloud SQL SLAs, meaning both db-f1-micro and db-g1-small instances should ...
