Even before the stay-at-home orders spiked the demand for digital learning platforms, MyMahi was architecting for scale. MyMahi, a New Zealand-based digital education company, built their student platform, which helps 8,000+ monthly active students track their learning journeys, with CockroachDB Core embedded in a technology stack that includes spot instances (e.g., AWS Fargate), serverless functions (e.g., AWS Lambda), and GraphQL (e.g., GraphQL.js, GraphQL Tools). Starting in 2018, MyMahi designed their new application to take advantage of technologies that allow them to scale out seamlessly in response to student activity. In this blog post, we'll highlight MyMahi’s application architecture and discuss how different technologies like AWS Lambda interact with CockroachDB to provide a scalable, serverless backend for their application.
