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.

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 – Currently in alpha testing FaaS service allowing functions to be triggered by events without developer resource management similar to Amazon Lambda or IBM OpenWhisk.

AWS VPC ELB CloudFront Direct Connect Route53
GCP Cloud VirtualNetwork1 Cloud LoadBalancing2 Cloud CDN Cloud InterConnect Cloud DNS

1GCP allows for 802.1q tagging (aka VLAN taggin). AWS does not.
2GCP allows for cross-region load balancing. AWS does not.


Storage services comparison
Object Block Cold File
AWS S3 EBS1 Glacier EFS
GCP Cloud Storage Compute Engine Persistent Disks2 Cloud Storage Nearline ZFS/Avere


1An EBS volume can be attached to only one EC2 instance at a time. Can attach up to 40 disk volumes to a Linux instance. Available in only one region by default.
2GCP Persistent Disks in read-only mode can be attached to multiple instances simultaneously. Can attach up to 128 disk volumes. Snapshots are global and can be used in any region without additional operations or charges.


Database services comparison
RDMS NoSQL (key-value) NoSQL (indexed)
AWS RDS DynamoDB DynamoDB
GCP Cloud SQL1 Cloud Bigtable2 Cloud Datastore


1MySQL only.
2100 MB maximum item size. Does not support secondary indexes.


Big Data services comparison
Streaming data ingestion Streaming data processing Batch data processing Analytics
AWS Kinesis Kinesis EMR Redshift
GCP Cloud Pub/Sub Cloud Dataflow Cloud Dataflow / Cloud Dataproc BigQuery


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.
BigQuery 
GCPs offering for a fully managed, massive data warehousing and analytics engine, allowing for data analytics using SQL.
Application services comparison
Messaging
AWS SNS
GCP Cloud Pub/Sub


Cloud Pub/Sub (publisher/subscriber)
Management services comparison
Monitoring Deployment
AWS CloudWatch CloudFormation
GCP Stackdriver Deployment Manager


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.
