Overview

The best way how Google share their
+ Cloud Infrastructure
+ Cloud Knowledge
+ Cloud Engineers
Your own data center, with minimum cost
as possible as it could be
What is Google Cloud Platform

You will be using Google's Infrastructure 
Virtual Machines 
Networking 
Storage
And be placed in a safe place 
Google's Data Center
And Google will do those for you 
Scaling 
Migrating 
Maintenance 
Take over anything you don't wanna do 
Powered by Google

Google Cloud Family

Manage all API services on Google
Cloud  
(e.g. Translation API, Prediction API, Maps API...)
Compose equivalent commands for: 
Command-line tools (Google Cloud SDK) 
RESTful API
Dashboard for monitoring all
resources on Google Cloud Platform
Cloud Developer Console

Install/uninstall/upgrade all
command-line tools related to
Notiﬁcation for new release of any
Cloud SDK component
Automatization
Google Cloud SDK

Storage
Storage Services in Google Cloud Platform

It's MySQL, but managed by Google
Relational Data Storage on Google Cloud
Use Cases
+ LAMP Applications
+ Google App Engine
Cloud SQL

Non-relational database (NoSQL)
Schema-less data
Use Cases
+ Highly scalable application
Cloud Datastore

Protected 
Your data is protected at multiple physical locations
Strong, conﬁgurable security 
OAuth or simple access control on your data
Multiple usages
+ Serve static objects directly
+ Use with other Google Cloud products (Bridge)
Cloud Storage

Google Compute Engine
Infrastructure-as-a-Service in Google Cloud Platform

Google has resources
+ CPU Cores
+ Memory
+ Networking
+ Persistency (Disks, Snapshot, Cloud Storage...)
+ Well-trained engineering monkeys
You have business and be busy
Infrastucture-as-a-Service

High-performance virtual machines 
from micro-VM to large instance
Powered by Google's global network 
you could build a large cluster with strong and consistent bandwidth, provided by
Google
Load Balancing 
spread incoming traﬃc across instances
Fast Bullet Reloading 
quick deployment of large VMs 
command-line interface 
web-based console
Highly secured 
All data written to disk in Compute Engine will be encrypted by high-class
encryption algorithm
Google Compute Engine

KVM-based Virtual machines
Fast booting time 
routinely takes less than 30 secs
Various OS support
Various machine types

Transparent Maintenance
Auto restart instances shutdown by system events
During transparent maintenance, you could set GCE to handle your
instance in two ways:
+ Live migrate 
aﬀect performance in some degree 
but remain your instances online (no downtime)
+ Terminate and reboot
Live Migration

Virtual SCSI device
Block Storage
Persistent until deleted
Hot-plug to GCE instances (attach/deattach)
Persistent Disk

Primary Disk: OS boot volume
Persistent Disk Mode
GCE Virtual Machine
Root
Stateful Root Volume

Additional Disk: Read/Write Mode for user managed data volume

Distribution Disk: Instant distribution of static content

Target Pools
Health Checking
Forwarding Rules 
iptables for target pools
Load Balancing

CGE reserved IP for instance, won't change with the reboot of VMs
You can promote ephemeral IP to persistent IP
no DNS changing anymore
Persistent IP Addresses

Networking is first-class object on GCE 
which means you could apply/unapply it anytime easily
pre-defined networks before the first instance started
Integrated Networking

Those resources are global resources
+ Images (OS Images)
+ Snapshots
+ Network
+ Firewalls
+ Routes
And they're also ﬁrst-class object in GCE

Health Checking Options Limited Preview
checkIntervalSec 
Determines how often, in seconds, to make HTTP requests for the health check.
healthyThreshold 
Sets the number of consecutive health check requests that must succeed before the replica is considered healthy. The default is
2 successful consecutive health checks.
timeoutSec 
How long to wait in seconds before claiming failures for a health check.
unhealthyThreshold 
The number of consecutive health check requests that need to fail to consider the replica unhealthy.
Only a HTTP 2xx response is considered successful.
