Exam Essentials
Understand the differences between Compute Engine, Kubernetes Engine, App Engine, and Cloud Functions. Compute Engine is Google’s VM service. Users can choose CPUs, memory, persistent disks, and operating systems. They can further customize a VM by adding graphics processing units for compute-intensive operations. VMs are managed individually or in groups of similar servers.
Kubernetes Engine manages groups of virtual servers and applications that run in containers. Containers are lighter weight than VMs. Kubernetes is called an orchestration service because it distributes containers across clusters, monitors cluster health, and scales as proscribed by configurations.
App Engine is Google’s PaaS. Developers can run their code in a language-specific sandbox when using the standard environment or in a container when using the flexible environment. App Engine is a serverless service, so customers do not need to specify VM configurations or manage servers.
