The blog post by Aydrian Howard describes the development of a serverless Ugly Sweater Voting Application designed to entertain a distributed team. The application features a serverless backend that facilitates SMS-based voting and real-time updates using technologies like Netlify, Twilio, CockroachDB, Next.js, and Pusher Channels. The app allows users to enter a contest by texting an image and name, and vote by texting the name of their choice, with Twilio managing the SMS functionality. CockroachDB serverless is utilized for scalable data storage, while Next.js is used for the frontend dashboard to display contest entries and votes. Pusher Channels enable real-time interactivity by updating vote tallies globally without needing manual page refreshes. Howard emphasizes the ease and scalability of the serverless architecture and encourages building with Pusher Channels based on their positive experience.
