    Not quite a Saab 900, but perhaps the Bollinger B-1? https://bollingermotors.com/bollinger-b1/

    We've been using Sleuth at LaunchDarkly as a single pane of glass for all changes going out into production. The addition of DORA metrics is exciting-- as an engineering leader, Ac…

    JSON Patch ( http://jsonpatch.com/ ) also uses it.

    There's VSCO, Fluid, Roofstock, LaunchDarkly, and Uber coming soon. There's probably a few more great companies that I'm forgetting.

    Fun fact-- it was started by one the founders of HipChat.

    That's mostly right. We don't use ES as a primary datastore, though.

    I mentioned this briefly in the article, but we thought about doing something with Lambda + API Gateway. But doing the math, 5k RPS pushed through API Gateway is about $1500 daily …

    We've thought quite a bit about how to make this work as a service. The key to our architecture is that evaluating a feature flag for a user does not involve a remote call. We make…

    We had a lot of operational experience with Mongo from our previous jobs at Atlassian, and started out storing almost everything in Mongo. As we scaled out, we migrated all of our …

    I think it depends on the workload. Serving 4.6k static pages per second, cached on a CDN, is not too difficult. However, handling an analytics workload of 4.6K RPS is a little har…

    I was being cheeky :) Events are stored in DynamoDB. We use mongo for "core" data like accounts, feature flags, etc, but none of the high throughput stuff touches MongoDB.

    For temporary feature flags, we try to clean up as soon as possible. As part of the rollout plan for a new feature, we'll have defined what metrics we're trying to achieve, and onc…

    Of course-- we have a dogfood instance of LaunchDarkly. We use LD as our plan permissioning system (the plans you see on our pricing page are managed by LD). We also use it for ops…

    Our goal is to build a developer-focused platform that gives teams the ability to adopt feature flags as a core part of their dev cycle-- including pretty much all of the use cases…

    We do have some features to help manage the lifecycle of feature flags. For example, we can determine when a flag has been "flipped on" for everyone, and notify you that it's time …

    We've been using DeployHub at LaunchDarkly for a bit now, and it's a great tool to have in our arsenal. The thing I like about it is that it focuses on doing one thing well. Too ma…

    Co-founder of LaunchDarkly here-- we're dropping our startup package to $9 / month in the next week. Come check us out.

    Thanks for the shout-out! One of the cool things about LaunchDarkly is that you can use it out-of-the-box without needing to provision any additional infrastructure. By default, th…

    We do have multiple feature flags in place at once. Our dogfood server (we use LaunchDarkly on LaunchDarkly) has about 30 feature flags going at any given time, and we're a relativ…

    I haven't heard of module flag-driven development-- would love to hear more details. We manage the cleanup issue by defining a "removal branch" that cleans up the feature flag at t…

    CTO of LaunchDarkly here. We kind of embrace it a little bit-- locavore booleans as a service. But the real power behind the idea is not the ifdef piece, it's the idea of dynamic, …
