The document discusses developing and deploying applications using hybrid cloud strategies. It provides examples of using different cloud platforms like Amazon Web Services, Windows Azure, and Orchestra for various infrastructure components including computing, storage, databases, and content delivery. It also discusses strategies for scaling applications on the cloud like using multiple servers, databases, caching, load balancing, and adapting application code.

- 12. What is Cloud?
- 13. “That’s where rain comes from” Andrei Zmievski
- 14. Cloud = Internet
- 15. DefiniXon A model for consumpXon & delivery on the internet where flexibility is essenXal & can be guaranteed through abstracXon
- 16. Internet as a uXlity
- 17. Translated to what we know & need
- 18. Always available
- 19. Fast (enough)
- 20. Scalability Up & down vs out & in
- 21. Focus on using, do what you’re good at
- 22. Leave the rest to others
- 24. Higher up the stack
- 26. Less money Less effort Less risk Less worries
- 27. Hybrid let’s you do that
- 28. Hybrid is just a fancy way of saying
- 29. Pick the pieces of the puzzle yourself
- 31. Amazon web services ✓CompuXng ✓Database –EC2 –RDS –ELB –DynamoDB –Auto –SimpleDB scaling –ElasXcache ✓Storage –SQS –S3 ✓CDN –EBS –CloudFront Self-‐service Iaas
- 32. Windows Azure ✓CompuXng ✓Storage –Blob storage –Table storage ✓CDN ✓SQL Azure ✓Data sync ✓Service Bus Self-‐service Paas
- 33. Orchestra ✓CompuXng ✓Database –Memcached –MySQL & RDS –CouchDB –MongoDB –Redis PHP Paas on top of AWS
- 34. Combell Fully customized & managed soluXons
- 37. Single point of failure
- 38. Shared nothing
- 39. Nothing is local
- 41. Easy to deploy & manage?
- 42. How do you deal with $_SESSIONS?
- 45. “Cloud is for green field projects” Maarten Balliauw
- 46. Let’s do it !
- 47. Infrastructure ✓Basics –Webservers –MySQL servers –File servers ✓AddiXonal servers –Caching servers –Reverse proxy servers ✓External CDN
- 49. Single server setup ✓Developer –Everything is local •Files •Databases ✓Sysadmin –Sits back, drinks some coffee
- 50. 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
- 51. Separate MySQL
- 52. Separate MySQL ✓Developer –Change connecXonstring(s) ✓Sysadmin –Sets up separate server –Tunes for MySQL
- 53. 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
- 54. MulXple MySQL’s
- 55. 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
- 56. MulXple Use mysqlnd_ms for R/W splimng in case of crappy code MySQL’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" } } } }
- 57. mysqlnd_ms.enable=1 mysqlnd_ms.ini_file=/path/to/mysqlnd_ms_plugin.ini php.ini <?php $mysqli = new mysqli("myapp", "username", "p assword", "database"); $pdo = new PDO('mysql:host=myapp;dbname=data base', 'username', 'password'); $mysql = mysql_connect("myapp", "username", "password"); ConnecXon string
- 58. MulXple MySQL’s What ✓Amazon about the –MulXple EC2 instances Cloud? with replicaXon and loadbalancing –RDS with read replica ✓Azure –Include PHP & MySQL in package script –Doesn’t scale –Use SQL Azure ✓Orchestra –RDS –Xeround
- 59. MulXple web servers
- 60. MulXple web servers ✓Developer –MulXple places to deploy –Where are my staXc assets? –Sessions? ✓Sysadmin –MulXple servers behind loadbalancer –$_SESSION clustering via Memcached or sXcky sessions –Shared storage
- 61. Memcached session handler session.save_handler = memcached session.save_path= “mc1.myapp.ext: 11211,mc2.myapp.ext:11211” php.ini
- 62. 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
- 63. Offload staXc files
- 64. 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?
- 65. Offload staXc files What ✓Amazon about the –EC2 instances for storage with Cloud? clustered file system –S3 buckets ✓Azure –Blob storage
- 66. When the pressure is on
- 67. Auto scaling & load balancing
- 68. CDN & asset offloading
- 70. Memcached
- 71. Adapt your code
- 72. Storage
- 73. 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 storage 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"); Amazon S3
- 75. <?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_DIRECT ORY => $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
- 76. Design pawerns Modular e.g. AbstracXon design Dependency injecXon layers
- 77. + W3 Total Cache
- 78. 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
- 82. Deploy your code
- 83. 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

- 89. Mix & match
- 90. Management models (oAen forgoBen)
- 91. Management models (oAen forgoBen) Managed Cloud is the new dedicated server Unmanaged Cloud is virtual colocaXon
- 92. Management models (oAen forgoBen) Custom soluXon at hoster under heavy SLA Burst model at unmanaged vendor
- 93. When to choose what?
