Google's new Cloud Technologies

New Google Cloud Technologies

● Google Storage○ Store your data in Google's cloud

● Prediction API○ Google's machine learning tech in an API

● BigQuery○ Hi-speed data analysis on massive scale

Google Storage for DevelopersStore your data in Google's cloud

What Is Google Storage?

● Store your data in Google's cloud○ any format, any amount, any time

● You control access to your data○ private, shared, or public

● Access via Google APIs or 3rd party tools/libraries

Sample Use Cases

Static content hostinge.g. static html, images, music, video Backup and recoverye.g. personal data, business records Sharinge.g. share data with your customers Data storage for applicationse.g. used as storage backend for Android, AppEngine, Cloud based apps Storage for Computatione.g. BigQuery, Prediction API

Google Storage Benefits

High Performance and Scalability Backed by Google infrastructure

Strong Security and Privacy Control access to your data

Easy to UseGet started fast with Google & 3rd party tools

Google Storage Technical Details● RESTful API

Google Prediction APIGoogle's prediction engine in the cloud

Google Prediction API as a simple example

Predicts outcomes based on 'learned' patterns

How does it work?

"english" The quick brown fox jumped over the lazy dog.

"english" To err is human, but to really foul things up you need a computer.

"spanish" No hay mal que por bien no venga.

"spanish" La tercera es la vencida.

? To be or not to be, that is the question.

? La fe mueve montañas.

... and many more ...

Using the Prediction API

1. Upload

2. Train

Upload your training data toGoogle Storage

Build a model from your data

Make new predictions3. Predict

A simple three step process...

Step 1: UploadUpload your training data to Google Storage

● Training data: outputs and input features ● Data format: comma separated value format (CSV)

"english","To err is human, but to really ...""spanish","No hay mal que por bien no venga."...

Upload to Google Storagegsutil cp ${data} gs://yourbucket/${data}

Step 2: TrainCreate a new model by training on data

To train a model:

POST prediction/v1.3/training{"id":"mybucket/mydata"}Training runs asynchronously. To see if it has finished:

GET prediction/v1.3/training/mybucket%2Fmydata

{"kind": "prediction#training",...,"training status": "DONE"}

Step 3: PredictApply the trained model to make predictions on new data

POST prediction/v1.3/training/mybucket%2Fmydata/predict{ "data":{ "input": { "text" : [ "J'aime X! C'est le meilleur" ]}}}

Step 3: PredictApply the trained model to make predictions on new data

POST prediction/v1.3/training/bucket%2Fdata/predict

{ "data":{ "input": { "text" : [ "J'aime X! C'est le meilleur" ]}}}

{ data : { "kind" : "prediction#output", "outputLabel":"French", "outputMulti" :[ {"label":"French", "score": x.xx} {"label":"English", "score": x.xx} {"label":"Spanish", "score": x.xx}]}}

Step 3: PredictApply the trained model to make predictions on new data

import httplib

header = {"Content-Type" : "application/json"}#...put new data in JSON format in params variableconn = httplib.HTTPConnection("www.googleapis.com")conn.request("POST", "/prediction/v1.3/query/bucket%2Fdata/predict", params, header)print conn.getresponse()

Prediction API - Pricing○ Free Quota

Google BigQueryInteractive analysis of large datasets in Google's cloud

Introducing Google BigQuery

● Google's large data adhoc analysis technology○ Analyze massive amounts of data in seconds

● Simple SQL-like query language

● Flexible access○ REST APIs, JSON-RPC, Google Apps Script

Many Use Cases ...

Spam TrendsDetection

Web Dashboards

Network Optimization

Interactive Tools

Key Capabilities of BigQuery

● Scalable: Billions of rows

● Fast: Response in seconds

● Simple: Queries in SQL

● Web Service○ REST○ JSON-RPC○ Google App Scripts

Using BigQuery

1. Upload

2. Import

Upload your raw data toGoogle Storage

Import raw data into BigQuery table

Perform SQL queries on table

3. Query

Another simple three step process...

Writing Queries

Compact subset of SQL○ SELECT ... FROM ...

WHERE ... GROUP BY ... ORDER BY ...LIMIT ...;

Common functions○ Math, String, Time, ...

Statistical approximations○ TOP○ COUNT DISTINCT

BigQuery via REST

GET /bigquery/v1/tables/{table name}

GET /bigquery/v1/query?q={query}

Sample JSON Reply:{ "results": { "fields": { [ {"id":"COUNT(*)","type":"uint64"}, ... ] }, "rows": [ {"f":[{"v":"2949"}, ...]}, {"f":[{"v":"5387"}, ...]}, ... ] }}Also supports JSON-RPC

BigQuery Security and Privacy

Standard Google Authentication● Client Login● AuthSub● OAuth

HTTPS support● protects your credentials● protects your data

Relies on Google Storage to manage access
