The cloud: a deﬁnition


NIST Working Deﬁnition of Cloud Computing


NIST Working Deﬁnition of Cloud Computing

“Cloud computing is a pay-per-use model for
enabling available, convenient, on-demand network
access to a shared pool of conﬁgurable computing
resources (e.g., networks, servers, storage,
applications, services) that can be rapidly provisioned
and released with minimal management effort or
service provider interaction.”

Amazon Web Services: EC2


EC2

• Create or destroy instances in minutes


EC2

• Many sizes: 1-20 Core(s) , 1.7-15GB RAM


EC2

• You can create custom VM images (AMI)


EC2

• Fixed IPs, persistent volumes, snapshots


EC2

• Fixed IPs, persistent volumes, snapshots
• You pay cpu time and data transferred


Amazon Web Services: S3 S3



• Create a bucket and put objects inside



• http://s3.amazonaws.com/bucket/object
or http://xxx.yoursite.com/object



• You can put an inﬁnite number of objects in
a bucket, objects have 5GB size limit



• You can put an inﬁnite number of objects in
a bucket, objects have 5GB size limit
• You pay storage, data transferred and
operations


Amazon Web Services: SimpleDB
SimpleDB


SimpleDB

• Key/Value store (not relational)


SimpleDB

• Domains, Items and Attributes


SimpleDB

• Very simple query language (no JOINs)

AWS and PHP

How do I build my PHP application on AWS?


AWS and PHP: Amazon libraries


AWS and PHP: Amazon libraries

Amazon “ofﬁcial” PHP libraries

✓ support all services
✓ many tutorials available
- verbose and often incostintent syntax
- not very well documented


AWS and PHP: Tarzan AWS

✓ full AWS support (S3, EC2, SQS,
SimpleDB, CloudFront)

✓ clean, consistent API
✓ well documented
http://tarzan-aws.com/


Examples: Upload a ﬁle to S3
<?php

require_once('tarzan.class.php');

$s3 = new AmazonS3();

$bucket = $s3->create_bucket('tarzan.test', S3_LOCATION_EU);

$file_url = $s3->store_remote_file(
'file://local.jpg',
'tarzan.test', 'remote.jpg', array( 'acl' => S3_ACL_PUBLIC)
);

?>


<?php

Include Tarzan
core class


'file://local.jpg',
);

?>


<?php
Create AmazonS3
object



'file://local.jpg',
);

?>


<?php

Create a new bucket that
will contain the ﬁle


'file://local.jpg',
);

?>


<?php


Upload a local ﬁle to S3
and make it public

'file://local.jpg',
);

?>


Examples: Get a ﬁle from S3
<?php



$file = $s3->get_object('tarzan.test', 'remote.jpg');

header('Content-type:' . $file->headers['content-type']);
echo $file->body;

?>


<?php

Get a handler to a
remote ﬁle


echo $file->body;

?>


<?php

Output the ﬁle
content to the client

echo $file->body;

?>


Examples: Run an EC2 instance
<?php

$ec2 = new AmazonEC2();

$run = $ec2->run_instances('ef48af86', 1, 1);
$instance_id = $run->body->instancesSet->item->instanceId;

$allocate = $ec2->allocate_address();
$ip_addr = $allocate->body->publicIp;
$associate = $ec2->associate_address($instance_id, $ip_addr);

?>


<?php
Include Tarzan class and
create AmazonEC2 object



?>


<?php
Create an EC2 instance of an
Ubuntu 8.04 LTS Hardy Server



?>


<?php

Allocate an Elastic IP (ﬁxed public IP) and
associate it with the instance created


?>


Examples: Manage an EC2 instance
<?php

$disassociate = $ec2->disassociate_address($ip_addr);
$ec2->release_address($ip_addr);

$ec2->reboot_instances(array(
'InstanceId.1' => $instance_id
));

$ec2->terminate_instances(array(
'InstanceId.1' => $instance_id;
));

?>


<?php

Disassociate and
'InstanceId.1' => $instance_id release the Elastic IP
));

));

?>


<?php


'InstanceId.1' => $instance_id Reboot the instance
));

));

?>


<?php


'InstanceId.1' => $instance_id
));
Shutdown the instance
));

?>


Examples: Elastic Book Stores
<?php

$volume_id = $ec2->create_volume(10, quot;us-east-1cquot;);

$ec2->attach_volume($volume_id, $instance_id, quot;/dev/sdhquot;);

$ec2->create_snapshot($volume_id);

$ec2->detach_volume($volume_id);

$ec2->delete_volume($volume_id);

?>


<?php


Create a persistent
$ec2->create_snapshot($volume_id); volume of 10 GB size


?>


<?php



Attach the volume to the
running instance as /dev/sdh


?>


<?php




Crate a snapshot (backup)
$ec2->delete_volume($volume_id); volume
of the
?>


<?php





Unmount the volume

?> from the running instance


<?php




Delete the volume


?>


Examples: SimpleDB, create items
<?php
$sdb = new AmazonSDB();

$domain = $sdb->create_domain('tarzan_test');

$put = $sdb->put_attributes('tarzan_test', 'testuser', array(
'name' => 'Test User',
'email' => 'test.user@gmail.com',
'password' => 'test',
'tags' => array(
'awesome',
'cool',
'fantastic'
)
));
?>


<?php


'name' => 'Test User', Create a domain named
“tarzan_test” that will store items
'tags' => array(
'awesome',
'cool',
'fantastic'
)
));
?>


<?php
$sdb = new AmazonSDB(); Create an item with
$domain = ID=”testuser”
$sdb->create_domain('tarzan_test');

'tags' => array(
'awesome',
'cool',
'fantastic'
)
));
?>


<?php


'tags' => array(
'awesome',
'cool',
Attributes have a key and
'fantastic' one or more values
)
));
?>


Examples: SimpleDB, query items
<?php

$q = $sdb->get_attributes('tarzan_test', 'testuser', 'password');

$q = $sdb->query('tarzan_test', array('MaxNumberOfItems' => 50));

$q = $sdb->$query('tarzan_test',
array( 'MaxNumberOfItems' => 10 ),
quot;['tags' = 'cool'] intersection ['tags' = 'awesome'] quot; .
quot;intersection not ['tags' = 'deleted']quot;,
true
);

?>


<?php


Get the password for
$q = $sdb->$query('tarzan_test', the user “testuser”
true
);

?>


<?php



Get the ID of 50 users
without any particular order
true
);

?>


<?php
Get at most 50 users that have
$q = the tags ”cool” and “awesome”
$sdb->get_attributes('tarzan_test', 'testuser', 'password');

$q =
but not the tag “deleted”
$sdb->query('tarzan_test', array('MaxNumberOfItems' => 50));

true
);

?>


<?php



true
);
Fetch all the attributes,
?> not only the IDs


Examples: Simple Queing Service
<?php

$sqs = new AmazonSQS();

$queue = $sqs->create_queue('tarzan_test_queue');

$message = $sqs->send_message('This is my message!');

$message = $sqs->receive_message();

$message = $sqs->delete_message($message_id);

$queue = $sqs->delete_queue();

?>


<?php

$sqs = new AmazonSQS(); Create the queue





?>


<?php


Push a message into the queue





?>


<?php


Remove temporaly a

message from the queue




?>


<?php



Remove permanently the

$message =
message from the queue
$sqs->receive_message();



?>


<?php





Destroy the queue


?>


What we have learned?

The cloud is real and it takes less than 5
minutes to start using it in you applications!

With Tarzan you can easily integrate the
powerful Amazon Web Services into you
application or start build one on them.
