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 […]

Feature Branching Using Feature Flags

Engineering teams have adopted distributed version control systems like GitHub and BitBucket to allow collaboration between developers within a central codebase and use branches (feature branching) to make updates or develop new features.  Unfortunately, feature branching has some shortcomings such as having code to be reverted or redeployed when application features need to be enabled or […]
