Progressive Delivery is an approach to software delivery that allows teams to gradually release new features and updates in a controlled and automated way.
This approach involves initially deploying new features to a small subset of users, then gradually increasing the number of users with access to the latest features based on performance and user feedback.
Progressive Delivery helps reduce the risk of failure and ensures users have a smooth and seamless experience with new updates.
When to use Progressive Delivery?
Here are some scenarios where Progressive Delivery can be useful:
- Large User Base: When teams have a large user base, managing the impact of updates on users is important. Progressive Delivery can help minimize the risk of downtime or errors that can result in lost revenue or reputation damage.
- Complex Systems: When software systems are complex, it can be challenging to ensure that new features or updates work as expected. Progressive Delivery allows teams to test new features or updates with a subset of users before releasing them to a larger audience.
- High Availability: When software systems require high availability, minimizing the risk of downtime or errors is essential. Progressive Delivery can help ensure that updates are reliable and performant, reducing the risk of downtime or errors.
- Limited Resources: When teams have limited resources, optimizing the software delivery process is important. Progressive Delivery can help teams release updates faster and more frequently without sacrificing reliability or performance.
Ways to Implement Progressive Delivery
There are several ways to implement Progressive Delivery, depending on the specific needs and requirements of the project. Here are some common ways to implement Progressive Delivery:
- Feature Flags: Feature flags are a popular way to implement Progressive Delivery. They allow teams to control the visibility of new features or updates, initially releasing new features to a subset of users and gradually expanding the release to more users based on performance and feedback.
- Canary Deployments: Canary Deployments involve releasing new updates to a small subset of users, typically 1% to 5%, and then gradually increasing the percentage of users with access to the latest features based on performance and feedback.
- A/B Testing: A/B Testing involves releasing two different versions of a feature or updates to different subsets of users and comparing the performance and user feedback to determine which version is more effective.
Advantages of using Progressive Delivery
There are several advantages of using Progressive Delivery, including:
- Reduced Risk: Progressive Delivery helps reduce the risk of failure or errors resulting in lost revenue or reputation damage. By releasing new features gradually, teams can monitor performance and user feedback and make adjustments as needed before releasing them to a larger audience.
- Faster Releases: Progressive Delivery enables teams to release new features and updates faster and more frequently without sacrificing reliability or performance.
- Better User Experience: Progressive Delivery ensures that users have access to new features and updates without disruption or downtime, improving their overall experience with the software.
- Cost-Effective: Progressive Delivery can help reduce the cost of software development and maintenance by enabling teams to identify and address issues early in the development process.
In conclusion, Progressive Delivery is an effective approach to software delivery that enables teams to release new features and updates gradually, reducing the risks of failure while ensuring that users have access to new features and improvements. It is particularly useful for scenarios where there is a large user base, complex systems,
