Review: Google Cloud AI lights up machine learning

Google Cloud AI and Machine Learning Platform is missing some pieces, and much is still in beta, but its scope and quality are second to none.

You can pick an AI Platform Deep Learning VM Image with TensorFlow, TensorFlow Enterprise, PyTorch, R, or half a dozen other frameworks. All images can include JupyterLab, and images intended for use with GPUs can have CUDA drivers.

You can create an instance from the gcloud command line (installed via the Google Cloud SDK) or from the Google Cloud marketplace. When you create your VM you can choose the number of virtual CPUs (the machine type, which also determines the RAM), and the number and kind of GPUs. You’ll see an estimate of your monthly cost based on the hardware you choose, with a discount for sustained usage. There’s no additional charge for the frameworks. If you choose a VM with GPUs, you need to allow a few minutes for installation of the CUDA drivers.

You can create a Deep Learning VM from the Google Cloud Console as well as from the command line. Note that the CUDA driver and JupyterLab installations each require only checking a box. The framework, GPU, machine type, and zone selections are done from drop-down lists.

AI Platform Deep Learning Containers

Google also supplies Deep Learning Containers suitable for use in Docker on your local machine or on Google Kubernetes Engine (GKE). The containers have all the frameworks, drivers, and support software you might want, unlike the VM Images, which allow you to select only what you need. Deep Learning Containers are currently in beta test.

AI Platform Pipelines

MLOps (machine learning operations) applies DevOps (developer operations) practices to machine learning workflows. Much of the Google Cloud AI Platform supports MLOps in some way, but AI Platform Pipelines are at the core of what MLOps is all about.

AI Platform Pipelines, currently in beta test, makes it easier to get started with MLOps by saving you the difficulty of setting up Kubeflow Pipelines with TensorFlow Extended (TFX). The open source Kubeflow project is dedicated to making deployments of machine learning workflows on Kubernetes simple, portable, and scalable. Kubeflow Pipelines, a component of Kubeflow that is currently in beta test, is a comprehensive solution for deploying and managing end-to-end machine learning workflows.

When Spotify switched its MLOps to Kubeflow Pipelines and TFX, some teams increased their number of experiments by 7x.

TensorFlow Extended is an end-to-end platform for deploying production machine learning pipelines. TFX makes it easier to implement MLOps by providing a toolkit that helps you orchestrate your machine learning process on various orchestrators, such as Apache Airflow, Apache Beam, and Kubeflow Pipelines. Google Cloud AI Platform Pipelines uses TFX Pipelines, which are DAGs (directed acyclic graphs), with Kubeflow Pipelines rather than Airflow or Beam.

You manage AI Platform Pipelines from the Pipelines tab of the AI Platform in your Google Cloud console. Creating a new pipeline instance creates a Kubernetes cluster, a cloud storage bucket, and a Kubeflow Pipeline. Then you can either define the pipeline from an example, or from scratch using TFX.

Spotify used TFX and Kubeflow to improve its MLOps. The company reports that some teams are producing 7x more experiments.

AI Platform Data Labeling Service

Google Cloud AI Platform Data Labeling Service lets you work with human labelers to generate highly accurate labels for a collection of data that you can use in machine learning models. The service is currently in beta test, and availability is very limited because of COVID-19.

AI Hub

Google Cloud AI Hub, currently in beta test, offers a collection of assets for developers and data scientists building artificial intelligence systems. You can both find and share assets. Even in beta form, AI Hub seems to be useful.

The Google Cloud AI Hub is a quick way to learn about, build, and share your AI projects on the Google cloud.

TensorFlow Enterprise

TensorFlow Enterprise provides users with a Google Cloud optimized distribution of TensorFlow with long-term version support. The TensorFlow Enterprise Distribution contains custom-built TensorFlow binaries and related packages. Each version of the TensorFlow Enterprise Distribution is anchored on a particular version of TensorFlow; all packages included are available in open source.

Google Cloud AI Solutions

Google aims AI Solutions at business executives rather than at data scientists or programmers. The solutions usually come with an optional consulting or contract development component; consulting services are also available separately. Underneath the covers, AI Solutions are based on AI Building Blocks and AI Platform.

Contact Center AI

Contact Center AI (CCAI) is a Google solution for contact centers designed to provide humanlike interactions. It builds on Dialogflow to provide a virtual agent, monitor customer intent, switch to live agents when necessary, and assist human agents. Google has half a dozen partners to help you develop and deploy a CCAI solution, and to support and train your agents.

Build and Use AI

Google Cloud Build and Use AI is a generically-defined solution that essentially offers Google’s AI expertise, AI Building Blocks, and AI Platform to solve your business problems. Among other benefits, this solution helps you to set up MLops with pipeline automation and CI/CD.

Document AI

Google Cloud Document AI applies the Google Vision API OCR building block along with Cloud Natural Language to extract and interpret information from business documents, typically supplied in PDF format. Additional components parse general forms and invoice forms. Industry-specific solutions for mortgage processing and procurement are currently under test. Google has half a dozen partners to help you implement Document AI solutions.

In praise of Google Cloud AI Platform 

Overall, the Google Cloud AI and Machine Learning Platform is very good, both in scope and quality. Whether you need to analyze language or images, use services out of the box, or use them with customizations to handle your own data, you’ll find the Google Cloud AI Platform at or near the state of the art. You can get your hands only as dirty as you need to. The days when you needed a Ph.D. in data science and a deep knowledge of TensorFlow to get a model trained and deployed are long gone.

The Google Cloud AI and Machine Learning Platform does have a few gaps, such as the lack of a first-party Google data preparation service, the lack of many on-premises options, and the fact that way too many of the services offered are still in beta test. Despite those issues, the Google Cloud AI can serve almost any machine learning or deep learning need. I especially like the new pipeline capabilities, even though it’s a beta test service based on open source products that are also still in beta test.

While I’m not going to speak further about the competition, some of which is also very good, I will say that in the sphere of AI applications, Google is essentially the new IBM, in that nobody ever gets fired for choosing Google AI.
