What is Cloud?
“That’s where rain comes from”
Andrei Zmievski
Cloud=
Internet
DefiniXon
A model for consumpXon & delivery on the internet where flexibility is essenXal & can be
guaranteed through abstracXon
Internet as a uXlity
Translated to what we know & need
Always available
Fast (enough)
Scalability
Up & down vs out & in
Focus on using, do what you’re good at
Leave the rest to others
Higher up the stack
Economic advantages
Less moneyLess effortLess risk
Less worries
Hybrid let’s you do that
Hybrid is just a fancy way of saying
Pick the pieces of the puzzle yourself
Amazon web services
✓CompuXng–EC2–ELB–Auto scaling
✓Storage–S3–EBS
✓Database–RDS–DynamoDB–SimpleDB–ElasXcache–SQS✓CDN–CloudFront
Self-‐service Iaas
Windows Azure
✓CompuXng✓Storage–Blob storage–Table storage✓CDN✓SQL Azure✓Data sync✓Service Bus
Self-‐service Paas
Orchestra
✓CompuXng✓Database
–Memcached–MySQL & RDS–CouchDB–MongoDB–Redis
PHP Paas on top of AWS
Combell
Fully customized & managed soluXons
Easy peasy, right?
Single point of failure
Shared nothing
Nothing is local
Distributed systems
Easy to deploy & manage?
How do you deal with
$_SESSIONS?
ReplicaXonR/W splimng
“Cloud is for green field projects”
Maarten Balliauw
Let’s do it !
Infrastructure
✓Basics–Webservers–MySQL servers–File servers✓AddiXonal servers–Caching servers–Reverse proxy servers✓External CDN
Single server setup
Single server setup
✓Developer–Everything is local•Files•Databases
✓Sysadmin–Sits back, drinks some coffee
Single server setup
✓Amazon–1 EC2 instance–Local MySQL or RDS (as a service)–Local files✓Azure–Single App deployment–Include PHP & MySQL in package script✓Orchestra–Single App deployment–Request MySQL database or RDS
What about the Cloud?
Separate MySQL
Separate MySQL
✓Developer–Change connecXonstring(s)✓Sysadmin–Sets up separate server–Tunes for MySQL
Separate MySQL
✓Amazon–Extra EC2 instance for MySQL–RDS✓Azure–MySQL deployment with worker role–Doesn’t scale well–Use SQL Azure instead✓Orchestra–By default separate–Create separate MySQL database–RDS
What about the Cloud?
MulXple MySQL’s
MulXple MySQL’s
✓Developer–Read write splimng in code–Connect to loadbalanced hostname
✓Sysadmin–Setup servers–Configure replicaXon•Master/master•Master/slave
–Add to loadbalancing
MulXple MySQL’s
Use mysqlnd_ms for R/W splimng in case of crappy code{ "myapp": { "master": { "write_group": { "host": "master.db.myapp.ext", "port": "3306" } }, "slave": { "read_group": { "host": "slave.db.myapp.ext", "port": "3306" } } }}
mysqlnd_ms_plugin.ini
mysqlnd_ms.enable=1mysqlnd_ms.ini_file=/path/to/mysqlnd_ms_plugin.ini
php.ini
<?php$mysqli = new mysqli("myapp", "username", "password", "database");$pdo = new PDO('mysql:host=myapp;dbname=database', 'username', 'password');$mysql = mysql_connect("myapp", "username", "password");
ConnecXon string
MulXple MySQL’s
✓Amazon–MulXple EC2 instances with replicaXon and loadbalancing–RDS with read replica
✓Azure–Include PHP & MySQL in package script–Doesn’t scale–Use SQL Azure
✓Orchestra–RDS–Xeround
What about the Cloud?
MulXple web
servers
MulXple web servers
✓Developer–MulXple places to deploy–Where are my staXc assets?–Sessions?
✓Sysadmin–MulXple servers behind loadbalancer–$_SESSION clustering via Memcached or sXcky sessions–Shared storage
Memcached session handler
session.save_handler = memcachedsession.save_path= “mc1.myapp.ext:11211,mc2.myapp.ext:11211”
php.ini
MulXple Web servers
✓Amazon–MulXple EC2 instances –Use ELB for loadbalancing–AMI for easy setup–Config management (puppet, chef, ...)
✓Azure–Out of the box–Tuning possible
✓Orchestra–Out of the box
What about the Cloud?
Offload staXc files
Offload staXc files
✓Developer–Sync current assets–Store new files on external servers–Use external hostname when referencing files
✓Sysadmin–Tune external servers for staXc content–CDN, perhaps?
Offload staXc files
✓Amazon–EC2 instances for storage with clustered file system–S3 buckets
✓Azure–Blob storage
What about the Cloud?
When the
pressure is on
Auto scaling & load balancing
CDN & asset offloading
Reverse (caching) proxy
Memcached
Adaptyourcode
Storage
require_once 'Zend/Service/WindowsAzure/Storage/Blob.php'; $storageClient = new Zend_Service_WindowsAzure_Storage_Blob();$result = $storageClient-‐>putBlob('testcontainer', 'example.txt', '/example.txt'); echo 'Blob name is: ' . $result-‐>Name;
require_once 'Zend/Service/Amazon/S3.php'; $s3 = new Zend_Service_Amazon_S3($my_aws_key, $my_aws_secret_key); $s3-‐>createBucket("my-‐own-‐bucket"); $s3-‐>putObject("my-‐own-‐bucket/myobject", "somedata");echo $s3-‐>getObject("my-‐own-‐bucket/myobject");
Azure Blog storage
Amazon S3
<?php$storage = Zend_Cloud_StorageService_Factory::getAdapter(array( Zend_Cloud_StorageService_Factory::STORAGE_ADAPTER_KEY => 'Zend_Cloud_StorageService_Adapter_S3', Zend_Cloud_StorageService_Adapter_S3::AWS_ACCESS_KEY => $amazonKey, Zend_Cloud_StorageService_Adapter_S3::AWS_SECRET_KEY => $amazonSecret,));$data = file_get_contents('/my/local/dir/picture.jpg');$returnedData = $storage->storeItem('/my/remote/path/picture.jpg', $data);
Supports Azure & AWS
<?php$storage = Zend_Cloud_StorageService_Factory::getAdapter(array( Zend_Cloud_StorageService_Factory::STORAGE_ADAPTER_KEY => 'Zend_Cloud_StorageService_Adapter_FileSystem', Zend_Cloud_StorageService_Adapter_FileSystem::LOCAL_DIRECTORY => $localDirectory,));$data = file_get_contents('/my/local/dir/picture.jpg');$returnedData = $storage->storeItem('/my/remote/path/picture.jpg', $data);
Even supports local file system

W3 Total Cache
✓Page caching -‐Memcached (loadbalanced)-‐ Varnish (loadbalanced)
✓Database & object cache-‐Memcached (loadbalanced)
✓CDN-‐ Push to S3 or Azure Blob storage buckets-‐ Pull from CDN (CloudFront or Azure)-‐ Custom hostnames
✓Scale across EC2 nodes with ELB

✓General deployment methods–Capistrano–Phing–Puppet (config is code too)–Version control tools
✓Amazon specific–AMI’s
✓Azure specific–Scaffolding & packaging command line tool–Upload packages in control panel
✓Orchestra specific–Git
