Unleashing Deploy Velocity with Feature Flags

A lot of development teams have built out fully automated CI/CD pipelines to deliver code to production fast! Then you quickly discover that the new bottleneck in delivering features is their existence in long-lived feature branches and no true CI is actually happening. This problem compounds as you start spinning up microservices and building features across your multi-repo architecture and coordinating some ultra-fancy release schedule so it all deploys together. Feature flags provide you the mechanism to reclaim control of the release of your features and get back to short-lived branches with true CI. However, what your not told about feature flags in those simple "if/else" getting started demos is that there is an upfront cost to your development time, additional complexities and some pitfalls to be careful of as you begin expanding feature flag usage to the organization. If you know how to navigate these complexities you will start to unleash true velocity across your teams.

In this talk, we'll get started with some of the feature flagging basics before quickly moving into some practical feature flagging examples that demonstrate its usage beyond the basic scenarios as we talk about UI, API, operations, migrations, and experimentation. We will explore some of the hard questions around "architecting feature flags" for your organization.

Microservice Code Sharing with .NET Service Templates

Sharing code and internal libraries across your distributed microservice ecosystem feels like a recipe for disaster! After all, you have always been told and likely witnessed how this type of coupling can add much friction to a world that is built for high velocity. But I'm also willing to bet you have experienced the opposite side effects of dealing with dozens of services that have had the same chunks of code copied and pasted over and over again, and now you need to make a standardized, simple header change to all services across your platform; talk about tedious, frictional, error-prone work. This is where service templates come in! A service template provides immense power to roll out changes that affect each service from a single code base. When built correctly, such a template stays far away from sharing any domain objects or business rules and focuses on delivering appropriate coupling between your services that allows your team to benefit from technical and operational component updates.

In this talk, we'll explore the architectural myth in microservices that you should NEVER share any code and explore the dos and don'ts of the types of reuse that you want to achieve through appropriate coupling. We will dive deep and look at some code of what a Service Template architecture looks like specifically in .NET, while also spending some time on the life cycle of that template and how it rolls out effectively to all your services. We will finish it off with some considerations and pain-points you might encounter with service templates in the organization.

Mono-repo or Multi-repo? Do I Need to Choose Just One?

Over the last few years, the dichotomy over Mono-repo vs Multi-repo approaches to source control has trended in the tech community and now heavily in the organization. If large organizations like Google and Facebook have been using mono-repos for a decade then shouldn't I be using them too? Like everything in software architecture, the answer is: "it depends!". While there are significant advantages to mono-repo style source control, there are significant disadvantages as well. Some developers swear by one approach over another, but in reality, you probably have different architectures that naturally would benefit from each style. Understanding when to use each approach over another is key to ensuring that you don't end up continually expanding and contracting your repository granularity without good reasons.

In this talk, we will move through a strong comparison of a mono-repo vs multi-repo approach. Each one represents a different set of values that may more closely align with your team or organization. We will cover the trade-offs, some workarounds and architectural considerations for helping you choose the correct style for your teams and projects.

Getting Started with Azure Pipelines

Azure Pipelines is a DevOps cloud-hosted tool from Microsoft that enables you to build efficient and streamlined CI/CD build and deployment pipelines for just about anything. Contrary to its name, it is cloud-agnostic and can provide your small or large team with a very flexible and inexpensive way of delivering your software with a high degree of consistency.

In this demo driven intro talk, we will dive into a brief overview of Azure DevOps and use Pipelines to build a CI/CD pipeline to deploy a service to Azure Cloud from GitHub. We will evolve our pipeline as we add in immutable versions, blue/green style deploys, containers, YAML, and make sure we get all the Pull Request status checks integrated as well. Then we will quickly convert it over to deploy into AWS!
