Continuous Deployment – Four Activities
(1) Deploy To Production
(2) Verify The Solution
(3) Monitor For Problems
(4) Respond & Recover

Release on Demand is considered as a core competence of every solution train and Agile Release Train (ART). This enables companies to respond to market opportunities with the highest quality solutions in the shortest time possible. This also helps customers capture market opportunities with their speed of innovation.

Companies looking to spend on-demand need corresponding production features and the ability to monitor and test them. Therefore, one excellent way to install a new version of the software in a production environment is to separate the installation process from the release process so that the changes made to a system during an upgrade are put in place without affecting the current operation of that system. This enables development teams to roll out features in smaller chunks so that the deployment of these changes can be done incrementally without disruption to end-users.

In this article, we’ll discuss Continuous Deployment, the practices used by Lean companies to get features into production more quickly.

CD is a workflow process through which validated features are moved from a staging environment to a production environment and ready for release. It is the third part of CDP.

Continuous Delivery Pipeline (CDP) has four parts:

Continuous Exploration (CE)
Continuous Integration (CI)
Continuous Deployment (CD)
Release On Demand

How Does Continuous Deployment Promotes Design Thinking And Value Flow?

CD separates the release and deployment process. It encourages the design thinking and value flow practice through:

(1) Targeting functions to Specific Customers - Separating the deployment from release allows the organization to reach customers with specific features so that the organization can evaluate the release impact before making functions available to all customers.

(2) Encouraging experimentation- Design thinking practices must be able to provide various functions to specific users and collect data to help create a design that is optimized for the user's needs.

(3) Promote small batches - Preliminary decisions are prepared, such as automated testing facilitates small-batch implementation.

(4) Release on business need - When deployment and release are separated and invested to ensure both are automated and risk-free, organizations can spend when needed, greatly increasing business agility.

(1) Deploy To Production

It describes the procedures required to be deployed to a production environment. Practices that promote this deploy activity:

Dark launches – The possibility of implementation in the production environment without revealing the functionality to end-users.
Feature toggles – Facilitates dark booting by installing code toggles that allow toggling between old & new features.
Deployment automation – The ability to automatically implement the tested solution from initial entry to production.
Selective deployment – The ability to deploy to specific production environments rather than others based on criteria such as geographic location, user role, and so on.
Self-service deployment – When an automation installation is not fully deployed, self-service deployment provides a single command to move solutions from downtime to production.
Version control – Support for a version control environment allows for quick installation and recovery.
Blue/green deployment – A technique that allows switching between development and production environments on-demand.

(2) Verify The Solution

This describes the procedures needed to ensure that the production changes work as intended. Once the installed changes are approved in production, they will be one step closer to release. Practices that promote this activity:

Production testing – An opportunity to examine solutions in production while they are even "dark".
Test automation – The possibility of retesting through automation.
Test data management – Manage test data in version control to ensure consistent automated testing.
Testing NFRs (Non-Functional Requirements) – System features such as security, performance, reliability, maintenance, serviceability, and scalability should also be thoroughly tested prior to release.

(3) Monitor For Problems

It details procedures for monitoring and reporting problems that may occur during production. While some business value metrics may not be captured until they are released, teams need to make sure they know how to evaluate them when a release solution is made. Practices that promote this activity:

Full-stack telemetry - Ability to troubleshoot stack issues across the entire system.
Visual displays - Tools that show automatic measurements.
Federated monitoring - Consolidated monitoring of all applications in the solution, making a complete view of problems and execution.

(4) Respond & Recover

This procedure describes how to quickly troubleshoot installation issues. Practices that promote this activity:

Proactive detection - The practice of proactively creating fault solutions to recognize probable challenges and circumstances before they arise.
Cross-team collaboration - Thinking about collaboration across the entire value stream to identify & resolve issues.
Session Replay - Ability to repeat end-user sessions to investigate incidents and analyze problems.
Rollback and fix forward - Ability to quickly roll back to the former environment and pipeline the problem quickly, no need to revert.
Immutable Infrastructure - It recommends that teams never uncontrollably change the production environment elements but manage infrastructure changes through CDP.
Version Control - The must be handled to quickly restore the environment.

After demonstrating that the functionality was successfully deployed to the production environment and that monitoring and remediation are needed to track and manage Continuous Value, teams have completed the CD phase of the CDP. This, in turn, gives the company the ability to release fast when needed.
