Controlling Releases with Microsoft VSTS + LaunchDarkly

Microsoft’s Visual Studio Team Services (VSTS) enables development teams to build, integrate, test, and release new software in a single platform. It has a centralized version control system that allows for continuous integration, package management, and release management. Together, these components enable agile teams to move faster in a more centralized manner while also minimizing […]

LaunchDarkly gets $8.7M for feature flag management

LaunchDarkly originally launched to nail a big pain point for developers that has been a luxury at larger companies for a while — soft-launching features and new code for a small set of users seamlessly and being able to quickly roll them back. But since the company launched and last raised $2.6 million in June, […]

Feature Toggles at Skylight

Skylight’s article on feature toggles shows how they allow their VIP customers (“Insiders”) to flip on features via a UI.  This allows users to control their own experience and experiment with new features before they are released. Skylight Insiders get a behind-the-scenes peek at features in development, allowing them to start using new features as […]

9 Chapter Comprehensive Guide to Feature Flagging

This github guide about feature flagging is open to contributors.  It talks about feature flagging best practices, avoiding technical debt, database migrations, and implementation strategies. An interesting overview of everything related to feature toggling. Table of Contents Introduction Uses Getting Started Cleaning Up Best Practices Flags vs Branching Blue-Green Deployments Database Migrations Implementation  

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 […]

Powering Blue-Green Deployments With Feature Flags

In Justin Baker’s article, he explains what and why we use blue-green deployments with feature flags.  The old form of blue-green deployments was basically an all-or-nothing approach.  However, current blue-green deployment techniques help reduce risks in software releases. Blue-green deployments have long been a proven technique to mitigate risk in software releases.  By adding feature flags, […]

Continuous Delivery

This small article by Jez Humble explains what continuous delivery is and the great benefits it brings.  Some of these benefits are low risk releases, faster time to market, higher quality, and lower costs.  Jez Humble has also written some books and recorded some videos that go more in-depth into what continuous delivery is. What is Continuous […]

Using Feature Flags to Ship Changes with Confidence

For those who are new to feature flags, it might be helpful to read Mathias Meyer’s blog which introduces and explains feature flags for continuous integration. Mathias also gives a list of possible uses for feature flags besides the common disabling of features in production.  If you want to ship with confidence, use feature flags. Continuous […]

How CI removes the pain

Neal Ford, a man who has given a continuous delivery workshop a few times with Martin Fowler, writes an article which includes a brief history of continuous integration (CI). Neal also explains what and how to best practice feature branching, feature flags, and feature toggles.  Moreover, Neal tells his readers how other engineering practices can be damaged […]

Powering Continuous Delivery With Feature Flags

In this article, Justin Baker discusses the benefits of feature flags when applied to continuous delivery.  He demonstrates the benefits of flags as a way to enhance continuous delivery, not replace it. Adding feature flags into the continuous delivery cycle enables the separation of feature rollout from code deployment.  This allows teams to conduct percentage rollouts, […]
