March 2022 Summaries

Fly.io runs applications by transforming Docker containers into Firecracker micro-VMs connected to a global Anycast network. The company uses Consul, a distributed database for service coordination and discovery, to manage its platform. However, they have faced challenges with Consul's design and performance at scale. Fly.io has developed attache, a local sqlite cache of all Consul's state, which allows their infrastructure services to track updates without directly interfacing with Consul. They are also considering alternative strategies for request routing that are resilient to variability and stale data.

Nolan Ruygt, a blind software developer working on accessibility at Fly.io, discusses the importance of incorporating accessibility into product design from the beginning. He emphasizes that accessibility is not just about accommodating people with disabilities but also improving overall user experience for everyone. Ruygt shares tips and tools to ensure accessibility in web applications, including automated testing, real-world user testing, and hiring individuals with lived experiences of disability. He also mentions his ongoing work on making LiveBeats, a model Phoenix LiveView application, more accessible.
