A single worker instance. This tier is suitable for learning how to use
Cloud ML, and for experimenting with new models using small datasets.
BasicGpu
A single worker instance with a K80 GPU.
BasicTpu
A single worker instance with a Cloud TPU.
Custom
The CUSTOM tier is not a set tier, but rather enables you to use your
own cluster specification. When you use this tier, set values to
configure your processing cluster according to these guidelines:
You must set ExecutionTemplate.masterType to specify the type
of machine to use for your master node. This is the only required
setting.
Premium1
A large number of workers with many parameter servers.
