A feature flag framework is a game-changing solution for software development. To release new software features with speed and accuracy, you must have access to a robust feature flagging tool that’s capable of enabling and disabling isolated features at your team’s command. In this guide, we will break down all you need to know about feature flag deployment and how it works.

Feature Flag Framework (What Is It?)

Using a feature flag framework, you can manage the functionality of software remotely without deploying any code. Feature flagging tools allow software developers to instantly enable and disable individual features. For instance, if you only want a certain segment of users to access specific features, you can leverage a feature flagging tool to isolate access to those features.

These tools give software development teams the ability to centrally manage feature rollouts from outside of the application. Teams can even restrict access to features after they have been rolled out to the end-users. This level of flexibility is ideal for software development teams that are continuously trying to refine features and successfully meet the needs of their end-users.

Feature Flag-Driven Development (Why Does It Matter?)

To ensure your team is rigorously testing software features before they are rolled out, the feature flag framework provides teams with the freedom to deploy code separately from the live rollout. Teams can use feature toggles to enable or disable features for different user segments. With the right feature flagging solution, you can achieve this without any interruption in service.

Before rolling out a feature as part of the default user experience, it is essential to utilize remote switches to manage the lifecycle of a feature. When you have the ability to rapidly change what users can see at the click of a button, you can experiment with confidence and push features further. An effective feature flagging tool will enable you to make quick and safe deployments.

Many developers assume that a feature flag framework is only beneficial in the pre-release testing of new features. In reality, nothing is further from the truth. Feature flags enable teams to deploy code into a live environment in an entirely controlled state. As a result, site maintenance and upgrades can take place without the need for any downtime or impact on end-users.

If your team were to discover a bug or general issue with a feature, they can use a feature flag to simply take the feature offline while they resolve the issue. When you have the right feature flagging platform in your corner, it is remarkably easy to disable individual features. Developers can sometimes use feature flagging tools to decommission older features and phase these out.

Feature Flag Deployment (Best Practices)

To guarantee safe feature flag deployment, you should consider a range of best practices. Let’s explore how you can fully harness the possibilities of feature flags with smooth deployments.

Understand When Feature Flags Are Required

When you deploy a feature flag, it should serve a specific purpose. Once the flag has served its intended purpose, you should consider removing it from the code. As there are many different potential use cases for feature flags, every situation is slightly different and will have its own timeline. Keeping feature flag deployment to a minimum allows your team to lead with simplicity.

Software development teams can use feature flags to personalize content for user segments. A project manager may wish to target a user segment and provide these users with access to a specific set of features. For instance, if this particular group of users is paying for premium access to the software, the team could utilize feature flags to offer features to premium users.

Establish Review Processes For Feature Flags

You should think carefully about adding IF statements to your software code. We recommend using feature flags sparingly and with intent. Adding unnecessary code to your software can result in avoidable headaches. The best thing your team can do is treat feature flags like production code. With this in mind, you should always thoroughly review any alterations.

For instance, you can add approval flows to your software development team processes to ensure feature flag changes are reviewed. Mistakes can happen. A project manager targeting a specific user segment could accidentally disable a feature for all users. Developing rigorous review processes for feature flag deployment will help to prevent mistakes from occurring.

Create Consistency Using Feature Flag Management Tools

To minimize the risks associated with deploying features to a live production environment, you need access to an effective feature flag solution. While feature flagging is an important part of delivering personalized user experiences, consistency is also critical to any rollout. This begins with making sure that all team members know how to successfully deploy feature flags.

With a user interface for feature flag management, those on your software development team can create and coordinate flags with ease. This is where a solution like ConfigCat comes into play. ConfigCat is a cross-platform feature flag service for software teams. If you are trying to complete quick and safe feature flag deployments, you need ConfigCat in your corner.
