What is Cloud?

“That’s where rain comes from”

Andrei Zmievski

Cloud=

Internet

DefiniIon

A model for consumpIon & delivery on the internet where flexibility is essenIal & can be

guaranteed through abstracIon

Internet as a uIlity

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

✓CompuIng–EC2–ELB–Auto scaling

✓Storage–S3–EBS

✓Database–RDS–DynamoDB–SimpleDB–ElasIcache–SQS✓CDN–CloudFront

Self-‐service Iaas

Windows Azure

✓CompuIng✓Storage–Blog storage–Table storage✓CDN✓SQL Azure✓Data sync✓Service Bus

Self-‐service Paas

Orchestra

✓CompuLng✓Database

–Memcached–MySQL & RDS–CouchDB–MongoDB–Redis

PHP Paas on top of AWS

CloudFlare

✓CDN✓DNS✓DDOS security✓Traffic analyIcs

ProtecIon SaaS

Combell

Fully customized & managed soluIons

Easy peasy, right?

Single point of failure

Shared nothing

Nothing is local

Distributed systems

Easy to deploy & manage?

How do you deal with

$_SESSIONS?

ReplicaIonR/W splibng

“Cloud is for green field projects”

Maarten Balliauw

Let’s do it !

Infrastructure

✓Basics–Webservers–MySQL servers–File servers✓AddiIonal 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 connecIonstring(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


MulIple MySQL’s

MulIple MySQL’s

✓Developer–Read write spliUng in code–Connect to loadbalanced hostname

✓Sysadmin–Setup servers–Configure replicaLon•Master/master•Master/slave

–Add to loadbalancing

MulIple MySQL’s

Use mysqlnd_ms for R/W splibng 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");

ConnecIon string

MulIple MySQL’s

✓Amazon–MulLple EC2 instances with replicaLon and loadbalancing–RDS with read replica

✓Azure–Include PHP & MySQL in package script–Doesn’t scale–Use SQL Azure

✓Orchestra–RDS–Xeround


MulIple web

servers

MulIple web servers

✓Developer–MulLple places to deploy–Where are my staLc assets?–Sessions?

✓Sysadmin–MulLple servers behind loadbalancer–$_SESSION clustering via Memcached or sLcky sessions–Shared storage

Memcached session handler

session.save_handler = memcachedsession.save_path= “mc1.myapp.ext:11211,mc2.myapp.ext:11211”

php.ini

MulIple Web servers

✓Amazon–MulLple 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


Offload staIc files

Offload staIc files

✓Developer–Sync current assets–Store new files on external servers–Use external hostname when referencing files

✓Sysadmin–Tune external servers for staLc content–CDN, perhaps?

Offload staIc files

✓Amazon–EC2 instances for storage with clustered file system–S3 buckets

✓Azure–Blog storage


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 Blog storage buckets-‐ Pull from CDN (CloudFront or Azure)-‐ Custom hostnames

✓Scale across EC2 nodes with ELB

Deploy your code

Deploy your code

✓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

Scale out

Mix & match

Management models (oAen forgoBen)


Managed Cloud is the new dedicated server

Unmanaged Cloud is virtual colocaIon


Custom soluIon at hoster under heavy SLA

Burst model at unmanaged vendor
