In the second installment of a three-part series about the tools used to operate ReadMe, the focus shifts to the behind-the-scenes infrastructure that supports the platform. Initially hosted on AWS, ReadMe transitioned to Heroku just before launch due to ease of use, although a future change is possible. The database is managed by Compose.io, formerly MongoHQ, which integrates Mongo, Redis, and Elasticsearch seamlessly, offering a user-friendly setup and reliable data syncing. This choice has proven efficient, saving significant time and effort. Other tools include CloudFlare for caching, Mailgun for email distribution, GitHub for code hosting, Slack for team communication, and Heap for dashboard analytics, which provides enhanced tracking capabilities compared to Google Analytics.
