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 InfrastructureVirtual MachinesNetworkingStorage

And be placed in a safe placeGoogle's Data Center

And Google will do those for youScaling 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 Google Cloud Platform

Notification for new release of any Cloud SDK component

Automatization

Google Cloud SDK

StorageStorage 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

ProtectedYour data is protected at multiple physical locations

Strong, configurable securityOAuth 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 machinesfrom micro-VM to large instance

Powered by Google's global networkyou could build a large cluster with strong and consistent bandwidth, provided by Google

Load Balancingspread incoming traffic across instances

Fast Bullet Reloadingquick deployment of large VMscommand-line interfaceweb-based console

Highly securedAll data written to disk in Compute Engine will be encrypted by high-class encryption algorithm

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 degreebut 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

Stateful Root Volume

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

GCE Virtual Machine

Stateful Root Volume

RW Data

Stateful Data Volume

Distribution Disk: Instant distribution of static content

RO Data

Read-Only Data Volume

Target Pools

Health Checking

Forwarding Rulesiptables 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 GCEwhich 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

Multi-Region Resources

Health Checking Limited Preview

Health Checking Options Limited Preview

checkIntervalSec Determines how often, in seconds, to make HTTP requests for the health check.

healthyThresholdSets 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.

unhealthyThresholdThe number of consecutive health check requests that need to fail to consider the replica unhealthy.

Only a HTTP 2xx response is considered successful.
