How Low Can You Go? Reducing Costs and Development Time with AWS Lambda, API Gateway, Elastic Beanstalk, and 3scale (and don't forget Swagger!)
More than 18,000 developers have keys to the Wordnik API, which they use to build everything from edtech applications to word games to Twitterbots! Our original architecture has served more than 2bn calls since 2010, and has largely been a free service.
When Wordnik relaunched as a nonprofit in late 2014, we realized we had to monetize our API to create a sustainable foundation for future development, and in order to monetize, we needed to reduce our operating costs and introduce new features -- neither of which our previous architecture made simple.
Enter AWS Lambda+API Gateway! By breaking down our current API into tiny functions, we can take advantage of the current microservice craze with minimal ops headaches. And by using Elastic Beanstalk and 3Scale to manage a reverse proxy, handling routing between the old and new API calls and managing billing is much easier, too. Add a pretty Swagger interface on top and you''re good to go ... faster and cheaper!
