Google Cloud Platform (GCP) is a cloud computing service by Google that offers hosting on the same supporting infrastructure that Google uses internally for end-user products like Gmail, Google Search, Maps, and YouTube.
Contents
Elements
- Google Compute Engine – IaaS service providing virtual machines similar to Amazon EC2.
- Google App Engine – PaaS service for directly hosting applications similar to AWS Elastic Beanstalk.
- BigTable – IaaS service providing map reduce services. Similar to Hadoop.
- BigQuery – IaaS service providing Columnar database. Similar to Amazon Redshift.
- Google Cloud Functions – FaaS service allowing functions to be triggered by events without developer resource management similar to Amazon Lambda or IBM OpenWhisk.
Details
- Connecting to a VM
$ gcloud compute --project "my-project-123456" ssh --zone "us-west1-b" "my-vm"
The above command will create SSH keys (stored in ~/.ssh
by default). After that, you can use the private key to SSH into your VM:
$ ssh -i ~/.ssh/google_compute_engine username@x.x.x.x
- Compute Engine Metadata
- The project metadata URL is:
http://metadata.google.internal/computeMetadata/v1/project/
- The instance metadata URL is:
http://metadata.google.internal/computeMetadata/v1/instance/
Each URL returns a set of entries that can be appended to the URL. Project settings contain info (e.g., project ID). Instance settings contain info on disks, hostname, machine
type, etc.
One can also set one's own values so that one can use them in code on the VM.
$ curl -H "Metadata-Flavor: Google" "http://metadata.google.internal/computeMetadata/v1/instance/service-accounts/default/token" {"access_token":"aa00...","expires_in":3599,"token_type":"Bearer"} $ curl -H "Metadata-Flavor: Google" "http://metadata.google.internal/computeMetadata/v1/project/" attributes/ numeric-project-id project-id
- Preemptible VMs
Preemptible VMs are highly affordable, short-lived compute instances suitable for batch jobs and fault-tolerant workloads. Preemptible VMs offer the same machine types and options as regular compute instances and last for up to 24 hours. If your applications are fault-tolerant and can withstand possible instance preemptions, then preemptible instances can reduce your Google Compute Engine costs significantly.

- Cloud Pub/Sub
- GCPs offering for data streaming and message queue. It allows for secure communication between applications and can also serve as a de-coupling method (a good way to scale).
- Dataflow
- GCPs managed service offering for batch and streaming data processing. Apache Beam under-the-hood.
- Dataproc
- GCPs offering for data processing using Apache Hadoop and Apache Spark. It is a massively parallel data processing and transformation engine.
- Supported services: MapReduce, Apache Hive, Apache Pig, Apache Spark, Spark SQL, PySpark, and support for parallel jobs with YARN.

Command Line Interface (CLI)
The Google Cloud SDK is a set of tools that you can use to manage resources and applications hosted on the Google Cloud Platform (GCP). These include the gcloud, gsutil, and bq command line tools. The gcloud command-line tool is downloaded along with the Cloud SDK.
