Deep dives
David's Background and Transition to Serverless
David Brucie shares his extensive experience of over 15 years at Amazon, where he initially worked in retail before shifting to AWS. He was a key contributor to the development of Amazon Cognito, focusing on identity management and syncing user data across devices. In 2020, he transitioned to Amplify Hosting, a continuous integration and delivery product for modern web applications. After leaving AWS in 2021, David began exploring innovative serverless ideas and started a company called Speedrun, which leverages Markdown to optimize manual tasks.
The Inception of Amazon Cognito
Cognito was developed to provide mobile app developers with secure access management solutions, enabling them to avoid embedding AWS credentials in their applications. This was originally accomplished through a token vending machine that provided temporary credentials. The team aimed to facilitate user data syncing across multiple devices, responding to a growing demand in the mobile space. The rapid design and development cycle led to its successful launch at the AWS Chicago Summit in 2014.
Common Use Cases for Cognito
Cognito is used in various ways, including direct access to AWS services from mobile apps without needing an API, often integrating with services like Lambda and API Gateway. User pools introduced in 2016 further enabled secure user authentication, including features like multi-factor authentication. Additionally, Cognito handles use cases related to Internet of Things (IoT) devices and supports authentication flows for both business-to-consumer and business-to-business applications. The ongoing evolution of its integrations highlights its importance as a front door for security in modern applications.
The Importance of Custom Authentication Flows
David emphasizes the significance of custom authentication flows in Cognito, which provide flexibility in managing different user authentication needs. By consolidating distinct authentication mechanisms into a unified interface, developers can design more dynamic user experiences. This adaptability allows for a variety of user verification methods, including traditional password entry and newer approaches like passwordless authentication. Such a design has been beneficial, enabling developers to address the unique requirements of their applications without overwhelming API surfaces.
Speedrun: Enhancing Developer Experience
David introduces Speedrun, a tool he developed to streamline task automation and improve the developer experience by integrating Markdown documentation directly with workflows. Speedrun allows users to create documentation that not only instructs but also directly executes commands within the development environment using a simple interface. This framework enables better collaboration among development teams, ensuring that documentation stays up-to-date and actionable. By minimizing the friction commonly encountered in operational tasks, Speedrun aims to create a more efficient process for developers.

David Behroozi, a 15-year Amazon veteran, tells us the inception story of Amazon Cognito and the cheat code for succeeding at AWS.
He also gave us a demo of Speedrun, his latest project since leaving Amazon. It turns your GitHub markdown into executable blocks of code that remember your context (e.g. AWS account and region) so your runbook can be executed right from the markdown.
