Continuous Integration and Deployment Best Practices on AWS

631

Published on

AWS Summit 2014 Brisbane - Breakout 5

With AWS companies now have the ability to develop and run their applications with speed and flexibility like never before. Working with an infrastructure that can be 100% API driven enables businesses to use lean methodologies and realize these benefits. This in turn leads to greater success for those who make use of these practices. In this session we'll talk about some key concepts and design patterns for Continuous Deployment and Continuous Integration, two elements of lean development of applications and infrastructures.

Presenter: Adrian White, Solutions Architect, Amazon Web Services

  7. 7. Automated Merging UAT Feature 2Feature 1
  8. 8. What does CI give us? •  Test driven promotion (of development change) •  Increasing velocity of feedback cycle through iterative change •  Contain change to reduce risk •  Bugs are detected quickly •  Automated testing reduces size of testing effort
  9. 9. What does CD give us? •  Changes are pushed quickly to production •  Immediate feedback from users •  Supports A/B testing or “We test customer reactions to features in production” •  Hardens, de-risks the deployment process •  Gives us a breadth of data points across our applications
  10. 10. Deployment approaches •  Deploy in place –  Manage interruption •  Bake –  Discrete environment •  Multiple environments from branches •  Support A/B testing •  “Rolling DNS” Deploy Deploy in-place Bake
  11. 11. Deploy in-place Un-baked •  Common baseline AMI •  Customise at instantiation •  Change in-place Your app AMI
  12. 12. Deploy in-place Un-baked •  Common baseline AMI •  Customise at instantiation •  Change in-place Your app AMI
  13. 13. Deploy in-place Un-baked •  Common baseline AMI •  Customise at instantiation •  Change in-place Your app AMI
  14. 14. Deploy in-place Un-baked •  Common baseline AMI •  Customise at instantiation •  Change in-place Your app AMI

  16. 16. Deploy in-place Un-baked •  Common baseline AMI •  Customise at instantiation •  Change in-place Your app AMI
  17. 17. Bake process 1.  Start a builder instance 2.  Bootstrap / cfn-init, cfn-signal 3.  Bake your AMI 4.  Tag it 5.  Destroy/clean up the builder instance
  18. 18. cfn-init "AWS::CloudFormation::Init" : { “cfn” : { "packages" :{ "yum" : { "httpd" : [] } }, "files":{ “/home/ec2-user/myfile.html:{ "source" : { "Fn::Join" : [ "", ["https://s3-ap- southeast-2.amazonaws.com/",{ "Ref" : "S3Bucket" },”/myfile.html”]] }, "mode":"000644", "owner":"root", "group":"root", "authentication":"S3AccessCreds” },

  32. 32. CloudFormation Custom Resources •  Change DB schema during deployment •  Extend CloudFormation to support other services - “So You Think You Are An AWS Ninja” talk https://github.com/aws/aws-cfn-resource-bridge https://github.com/awslabs/aws-cfn-custom-resource-examples Parameters Custom resource implementation Git
  33. 33. Custom resources – DatabaseSchema "MyDBSchema" : { "Type" : "Custom::DatabaseSchema”, "Version" : "1.0", "Properties" : { "ServiceToken": "arn:aws:sns:us-east-1:12345EXAMPLE:DBSchema", "databaseChangeLog" : [ { "changeSet" : { "id" : "1", "author" : "adamthom", "changes" : [ { "createTable" : { … } } ] } } } }
  34. 34. Custom resources – DatabaseSchema "createTable" : { "tableName" : "example", "columns" : [ { "column" : { "name" : "id", "type" : "int", "autoIncrement" : true, "constraints" : { "primaryKey" : true, "nullable" : false } } } ] }
  35. 35. Extending your CD tools Tasks for AWS DynamoDB
  36. 36. Situational Awareness Burden of Responsibility APIs Tasks for AWS
  37. 37. Containerisation •  Build environments for artifacts, don’t update environments with artifacts •  All environments are transient •  Standardisation, abstraction and portability
  38. 38. Docker, Amazon Linux and Elastic Beanstalk •  A framework for managing containers •  LXC containers are more lightweight than VMs •  Amazon Linux (2014.03) bundles Docker 0.9 and LXC 0.9 •  Docker containers on Beanstalk are Go!
  39. 39. Innovation, Quality, Governance Discrete environments for each branch Automated testing on every commit on every branch Leverage CD tools to provide separation of duties Audit Logs Git approvals process Use custom resources to extend CloudFormation Leverage DNS Interface with the API Environments for artifacts
