Successful Practices for Continuous Delivery

Infrastructure as Code and DevOps practices are necessary pre-requisites for safely adopting Continuous Delivery. This talk will explore some of the practices your team will need to adopt to safely move fast, continuously delivering value to your customers. It will include a demonstration of Chef's proven approach to a DevOps workflow including Chef Compliance, Chef Delivery, and more.

This was presented at the DevOpsDC Meetup Group.

11. The game changer: rapid time to value Innovation Quality/ Compliance Dynamic Infrastructure
12. Dynamic infrastructure Migrate applications to the cloud and support hybrid and multi-cloud environments. Automate the management of heterogeneous networks, including legacy systems. •  Provisioning and setting up environments •  Dynamic scaling of compute resources •  Migrating legacy workloads to the cloud •  Multi cloud and hybrid cloud deployment •  Support for heterogeneous environments
13. The game changer: rapid time to value Innovation Quality/ Compliance Dynamic Infrastructure Infrastructure as Code Automate the Stack +
14. Infrastructure as Code •  Programmatically provision and configure components •  Treat like any other code base •  Reconstruct business from code repository, data backup, and compute resources
15. Automation Turn infrastructure into code—infrastructure as code is versionable, testable and repeatable. Manual processes become a thing of the past. •  Automated, full-stack application policies •  Package and service installation •  Versionable, testable, repeatable workflow •  Scalable application policies •  Management of interdependencies across nodes
16. Describe Infrastructure as Code httpd_service 'customers' do mpm 'prefork' action [:create, :start] end httpd_config 'customers' do instance 'customers' source 'customers.conf.erb' notifies :restart, 'httpd_service[customers]' end directory '/var/www/customers/public_html' do recursive true end
17. Test the Code describe 'apache::default' do context 'When all attributes are default, on an unspecified platform' do let(:chef_run) do runner = ChefSpec::ServerRunner.new runner.converge(described_recipe) end it 'converges successfully' do expect { chef_run }.to_not raise_error end it 'installs apache' do expect(chef_run).to install_package 'apache2' end end end

20. DEVOPS A cultural and professional movement, focused on how we build and operate high velocity organizations, born from the experiences of its practitioners.
21. PEOPLE PRODUCTS COMPANIES
22. WE ARE LEAN •  Eliminate non-value-added action (Waste/Muda) •  Pull over Push •  Kaizen (Continuous Improvement) •  Kaikaku (Disruptive Change) •  Small Batch + Experimentation
24. UBIQUITOUS WORKFLOW AUTOMATION
25. DIVERSITY
26. DevOps workflow & culture Eliminate silos and lower the overhead of IT operations and service management by supporting DevOps culture. Build communities. •  Unified workflow for application and infrastructure •  Integration with version control for dev and ops •  Support for automated testing of infrastructure and applications •  Integration of security and compliance into product development •  Advanced, high-velocity workflow
27. The rewards?* *source: Dr. Nicole Forsgren research on DevOps More deployments Ship faster Faster MTTR after issues More profits, market share, and productivity Market cap goes up
28. Continuous delivery of infrastructure & apps Implement a high-velocity software delivery pipeline that integrates application and infrastructure. Eliminate the risks incurred with large, infrequent releases. •  Rapid provisioning of dev and test environments •  Ensure consistency and repeatability of environments •  Unified pipeline for infrastructure, runtime environments and applications •  Support for large teams with multiple projects •  Advanced, high-velocity workflow
31. MANAGE RISK •  Small batches, near term hypothesis •  Validation comes from customers •  Introduce near-term volatility to gain decreased long-term risk
32. CONTINUOUS INTEGRATION •  Always integrate branches to master •  They should be short lived, iterative branches •  Fix the build when it goes red
33. THE FOUR-EYE RULE
34. WRITE TESTS •  Unit test (a single function) •  Integration tests (multiple classes/units) •  Functional tests (user-oriented, high-level, full stack) •  Smoke tests (quickly determine if the system is “working”)
35. ONE PATH FOR CHANGE •  The way change moves through your organization is fixed •  Designed to re-enforce your principles and aid flow •  Flexible at the level of execution
36. CODE GOES THROUGH THE SAME WORKFLOW Applications are code Infrastructure is code
37. Security and compliance at velocity Regulatory compliance and security concerns are facts of life for every enterprise. At the same time, competitive pressures are increasing. Embed requirements into the software delivery pipeline. Code makes compliance at velocity possible. •  Embed compliance into the software delivery pipeline •  Automated checking of compliance criteria with analytics •  Structured review process during development •  Discovery and analysis •  Patch management and remediation
