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 money Less eﬀort Less riskLess 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 ✓Database –EC2 –RDS –ELB –DynamoDB –Auto –SimpleDB scaling –ElasXcache ✓Storage –SQS –S3 ✓CDN –EBS –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

CombellFully 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 What ✓Amazon about the –1 EC2 instance Cloud? –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

Separate MySQL

Separate MySQL ✓Developer –Change connecXonstring(s) ✓Sysadmin –Sets up separate server –Tunes for MySQL

Separate MySQL What ✓Amazon about the –Extra EC2 instance for MySQL Cloud? –RDS✓Azure –MySQL deployment with worker role –Doesn’t scale well –Use SQL Azure instead✓Orchestra –By default separate –Create separate MySQL database –RDS

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 Use mysqlnd_ms for R/W splimng in case of crappy codeMySQL’s{ "myapp": { "master": { "write_group": { "host": "master.db.myapp.ext", "port": "3306" } mysqlnd_ms_plugin.ini }, "slave": { "read_group": { "host": "slave.db.myapp.ext", "port": "3306" } } }}

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 What ✓Amazon about the –MulXple EC2 instances Cloud? with replicaXon and loadbalancing –RDS with read replica✓Azure –Include PHP & MySQL in package script –Doesn’t scale –Use SQL Azure✓Orchestra –RDS –Xeround

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 handlersession.save_handler = memcachedsession.save_path= “mc1.myapp.ext:11211,mc2.myapp.ext:11211” php.ini

MulXple Web servers What ✓Amazon about the –MulXple EC2 instances Cloud? –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 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 What ✓Amazon about the –EC2 instances for storage with Cloud? clustered file system –S3 buckets✓Azure –Blob storage

When the pressure is on

Auto scaling & load balancing

CDN & asset oﬄoading

Reverse (caching) proxy

Memcached

Adapt yourcode

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; Azure Blog storagerequire_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"); 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 Put supports local opXons in file system config file

Design pawerns Modular e.g. AbstracXon designDependency injecXon layers

+ W3 Total Cache

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

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
