Introduction to the Google Cloud Platform

Differences:

  • IaaS infrastructure as a service : Google computer compute engine GCE , aws
  • Paas Platform as a Service : Google App Engine, AWS Elastick beanstalk
  • SaaS: Software as a service Wordpress.com , google docs

Why google is better thant aws

  • GCA storage can read from other machines.
  • Global cros Region: the AMI can be read globally , in aws you need to copy the image
  • Ephemeral ip can be promoted to reserved engine
  • Integration with Google apps, drive, ecc.
  • the web interface is more simpler than asw
  • you can do ssh login by the browser

  • the stack feature is similar to elastick beanstalk on aws but
  • the project are a group of resources and it is a way to give permissions to users and setup other rules by group (firewall for example)

glcoud command line tool

## download and install the command line

storeage

Storage ==> Cloud Storage ==> Storage browser
you have the bucket like aws

Storage ==> Cloud Database
at the moment there is only one database mysql, amazon has a lot of db available in rds but probably they will add in the future.
seems possible switch off the database to sleep

security

keep the debian system upgraded
sudo apt-get install unattended-updgrade
sudo dpkg-reconfigure -plow unattended-upgrade

lock the root account
sudo usermod -L root

DRA means durable
-l is the region US-CENTRAL1 is the default region

list all the bucket associated with this project
