Develop and deploy using Hybrid Cloud Strategies confoo2012
- 1. Develop & deploy using hybrid cloud strategies Thijs Feryn Evangelist +32 (0)9 218 79 06 thijs@combellgroup.com
- 2. Very excited to be here !
- 3. THIJS
- 5. TAZE
- 6. Evangelist
- 10. @ThijsFeryn
- 11. Please rate my talk on Joind.in https://joind.in/4951
- 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?
