What is "The Cloud"?

Cloud computing is the acquisition and use of computing resources that are delivered as a service on an as-needed basis.

"The Cloud"

•  Evolution of distributed computing and Service-oriented Architecture (SOA).

•  Benefits – No upfront investment – Low ongoing cost – Flexible capacity – Speed & agility – Apps not ops – Global reach

( http://aws.amazon.com/what-is-cloud-computing/ )

Bringing you the “The Cloud” since 2006.

Amazon Web Services offers a complete set of infrastructure and application services that enable you to run virtually everything in the cloud: from enterprise applications and big data projects to social games and mobile apps.

How do I use AWS?

AWS Console

AWS SDKs and Tools

PHP • Java • Python • .NET

Ruby • Node.js • iOS • Android

SDKs

Unified CLI • Visual Studio Plugin

Eclipse Plugin • PowerShell Tools

Tools

General SDK Features

•  Suite of HTTP clients

•  Input and output serialization

•  Protocol normalization

•  Authentication

•  Error handling

•  Language-specific conveniences

•  Open source

The AWS SDK for PHP

http://github.com/aws/aws-sdk-php

Quick History

•  Tarzan (Started by @skyzyx)

•  CloudFusion

•  AWS SDK for PHP [2010]

•  AWS SDK for PHP 2 [Late 2012]

AWS SDK for PHP Features

•  PHP 5.3+, PSR compliant

•  Persistent connections, parallel requests

•  Event hooks, plugins, and wire logging

•  Simple array-style inputs and outputs

•  Iterators, waiters, and batching helpers

•  Higher-level abstractions

require 'vendor/autoload.php'; use Aws\S3\S3Client; $s3 = S3Client::factory(array( 'key' => 'your-‐aws-‐access-‐key-‐id', 'secret' => 'your-‐aws-‐secret-‐key', )); $result = $s3-‐>putObject(array( 'Bucket' => 'my-‐cool-‐photos', 'Key' => 'photo.jpg', 'Body' => fopen('./photo.jpg', 'r') ));

Built on Guzzle

•  Popular HTTP Library – Goutte – AWS SDK for PHP J – Drupal 8

•  Foundation of the SDK

•  Symfony2 Events

•  http://guzzlephp.org

Installing the PHP SDK

•  Composer

•  PEAR

•  Downloadable Phar

•  RPM/yum (on Amazon Linux)

Composer

•  Dependency management

•  Autoloader for project

•  http://getcomposer.org

Installing via Composer

In your composer.json file: { "require": { "aws/aws-‐sdk-‐php": "2.*" } }

On the command line. php composer.phar install

Concepts in the SDK

•  Commands

•  Modeled Results

•  Iterators

•  Waiters

•  Events & Plugins

•  High-level Abstractions

Commands

•  Encapsulates an operation to AWS

•  Contains Request and Response objects

•  Allows you set and get parameters

•  Returns modeled results

Commands - Shorthand

$result = $s3-‐>listObjects(array( 'Bucket' => 'my-‐bucket-‐name' )); echo $result['Objects'][0]['Key'];

$command = $s3-‐>getCommand('ListObjects'); $command-‐>set('Bucket', 'my-‐bucket-‐name'); $result = $command-‐>getResult(); echo $result['Contents'][0]['Key']; $response = $command-‐>getResponse(); echo $response-‐>getStatusCode(); echo $response-‐>getHeader('Content-‐Length');

The Command Object

$c1 = $s3-‐>getCommand('PutObject', array( 'Bucket' => 'my-‐bucket-‐name', 'Key' => 'my-‐first-‐key', 'Body' => fopen('path/to/file1', 'r') )); $c2 = $s3-‐>getCommand('PutObject', array( 'Bucket' => 'my-‐bucket-‐name', 'Key' => 'my-‐second-‐key', 'Body' => fopen('path/to/file2', 'r') )); $s3-‐>execute(array($c1, $c2));

Parallel Commands

Modeled Results

•  Array-like object •  Follows schema from service description •  Convenience methods like getPath()

$result = $s3-‐>listBuckets(); $result['Buckets'][0]['Name']; $result-‐>get('Buckets'); $result-‐>getPath('Buckets/0/Name'); $result-‐>get('Buckets'); print_r($result-‐>toArray());

Waiters

•  Poll resources until available •  Handle asynchronous and eventually

consistent operations more easily

$s3-‐>createBucket(array( 'Bucket' => 'my-‐bucket' )); $s3-‐>waitUntilBucketExists(array( 'Bucket' => 'my-‐bucket' ));

Iterators

•  Iterate through entire result sets •  No handling of markers or tokens •  Uses SPL iterators and interfaces

$list = $s3-‐>getIterator('ListObjects', [ 'Bucket' => 'my-‐bucket' ]); foreach ($list as $object) { echo $object['Key'] . PHP_EOL; }

SDK 1.x – Before Iterators $dynamo_db = new AmazonDynamoDB(); $start_key = null; $people = array(); do { $params = array( 'TableName' => 'people', ); if ($start_key) { $params['ExclusiveStartKey'] = array( 'HashKeyElement' => array( 'S' => $start_key ) ); $start_key = null; } $response = $dynamo_db-‐>scan($params);

if ($response-‐>isOK()) { foreach ($response-‐>body-‐>Items as $item) { echo (string) $item-‐>name-‐>S; } if ($response-‐>body-‐>LastEvaluatedKey) { $start_key = (string) $response-‐>body-‐>LastEvaluatedKey-‐>HashKeyElement-‐>S; } } else { throw new DynamoDB_Exception('DynamoDB Scan operation failed.'); } } while ($start_key);

$db = $aws-‐>get('DynamoDb'); $scan = $db-‐>getIterator('Scan', array( 'TableName' => 'People', 'AttributesToGet' => array('Id', 'Name') )); foreach ($scan as $person) { echo $item['Name']['S']; }

Example: Scan Iterator

Events & Event Listeners

•  Event slots in various parts of SDK •  Inject logic without extending classes •  Symfony2 Event Dispatcher

$s3-‐>getEventDispatcher() -‐>addListener('<event>', <fn>);

Plugins

•  Implemented as event listeners •  Many built-in plugins from Guzzle

including easy wire logging

use Guzzle\Plugin\Log\LogPlugin; $s3-‐>addSubscriber( LogPlugin::getDebugPlugin() );

Higher-level Abstractions

•  S3 Multipart Uploader

•  S3 Stream Wrapper

•  DynamoDB Session Handler

•  DynamoDB WriteRequestBatch

•  SNS Message Validator

•  Third-party Modules: ZF2, Silex, Laravel

$s3 = $aws-‐>get('S3'); $uploader = UploadBuilder::newInstance() -‐>setClient($s3) -‐>setSource('/path/to/large/file.mov') -‐>setBucket('my-‐bucket') -‐>setKey('my-‐object-‐key') -‐>setConcurrency(3) -‐>build();
