Soft Launches Using Feature Flags

This article discusses the benefits of using feature flags for soft launching new features. A feature flagged soft launch changes this. It allows you to mitigate the risk of feature releases and incrementally roll out a feature to your users. Some benefits include: Releasing a feature ‘off’ in production and then slowly rolling it out […]

Continuous Delivery Coding Patterns: Latent-to-Live Code & Forward Compatible Interim Versions

In this article, Luca Minudel discusses how to release faster without increased risk. He provides an overview of trunk-based-development & feature toggles. Key takeaways It’s possible to simultaneously increase speed and reliability of software development, and reduce risks; there’s no need to tradeoff quality and safety for speed. Continuous delivery together with latent-to-live code patterns maximise […]

When feature flags go wrong

In this article, Edith Harbaugh discusses the potential pitfalls of feature flags and how to avoid those mistakes. Key takeaways Feature flags are a valuable technique to deliver better, more reliable software faster Feature flags can be used for both release management (dark launches, canary rollouts, betas) as well as long term control (entitlement management, […]

Continuous Delivery Coding Patterns – Feature Toggles

This InfoQ article discusses the use of feature toggling as a new nomenclature term for continuous delivery.  It also discusses trunk-based development with an overview of feature toggles. Key takeaways It’s possible to simultaneously increase speed and reliability of software development, and reduce risks; there’s no need to tradeoff quality and safety for speed. Continuous […]

Bitbucket Pipelines: Continuous delivery in the cloud

Atlassian’s Bitbucket Pipelines tool helps teams build, test, and deploy applications without having to set up a CI/CD server. This is an interesting tool because you can integrate feature flags/toggles into your CI/CD pipeline to control feature releases.  This allows you to have flags turn on/off or to automate certain sorts of targeting during releases. Atlassian […]

The Future of Feature Flags: Managing Dynamic Applications

This article explores the various use cases that are made possible by multivariate feature flags.  With the introduction of multivariate flags, developers have been experimenting with serving rich values via these flags: strings, numbers, JSON objects, and JSON arrays. Using feature flags to manage dynamic applications opens up many powerful and interesting use cases, for example: Manage features […]

Feature Toggle Management with Hobknob

Hobknob is a feature toggle front-end built on top of etcd. It allows users to create and modify feature toggles, which can then be accesesed in your applications. Convention Features in Hobknob are grouped by application. Each application can have many, uniquely named features. Each feature will either have one on/off toggle or many on/off […]
