Deployment & Release are distinct with different purposes ii. Deployment – installing a specified version to a given environmentiii. Release – when a feature is made available to customers. 1. Release of functionality actions, release becomes a business decisions, not a technical decision v. Environment-based Release Pattern – multiple environments available, only one is receiving live traffic. Release performed Application-based Release Pattern – modify application to selectively release functionality by small configuration changes. Feature flags, dark launching h. ENVIRONMENT-BASED RELEASE PATTERNS i. Enables

Even so, the program must maintain a big picture, long-term view and focus on the next six-month release.  DO epics and user stories to concisely define the desired system functions and provide the foundation reviews during the release planning phases. To demonstrate functionality and provide insight into the program’s progress, these reviews should focus on the relatively small scope of a release and how it aligns aligns to the enterprise architecture. Similar technical reviews can be decomposed to the release level.  DO continuous planning at every levelSystems Engineering Role Program leaders must encourage

In DevSecOps, testing and security are shifted to the left application can be deployed into the production environment. Deployment frequency: how often a new release can be deployed into the production environment. Production failure rate: how often software fails

If negative results, ideally feature toggle off and fix-forward or use other Blue- Green, Canary release patterns b. DEV SHARES PAGER ROTATION DUTIES WITH OPS i. Complex systems will inevitably have unexpected also increase maintenance costs and identify opportunity costs. d. INTEGRATE A/B TESTING INTO OUR RELEASE i. A/B testing requires fast CD to support ii. Use feature toggles to control experiments, cohort great metric to publish widely is how many meetings and work tickets are mandatory to perform a release – the goal is to relentlessly reduce the effort required for engineers to perform work and deliver

Development has worked on is released to production deployment. Like in manufacturing, this large batch release creates sudden, high levels of WIP and massive disruptions to all downstream work centers, resulting Successful Brownfield transformations 1. CSG – COBOL mainframe and supporting applications a. They 2X release frequency b. Resulted in increased application reliability c. Reduced deployment lead time from ensuring service levels are met v. Infosec – team responsible for securing systems and data vi. Release Managers – the people responsible for coordinating the production deployment processes vii. Technology

Continuous Delivery in Financial Training by David Genn (IG) @david_genn  Separate deployment from release  Automate everything  Trust your tests  Conversations are way better than project proposals

capabilities at least match those of the legacy system. Because this usually takes a while, the first release of the new system doesn’t come for quite some time, which works against the Agile principle of delivering
