One of the benefits of GraphQL is that it enables a single entry point into any number of back end service or databases. More and more companies are adopting cloud technologies – leading to more jobs, more money, and more opportunities in cloud computing. When GraphQL is integrated with a cloud back end, enabling secure and direct access to dozens of databases and managed services, the limitations are endless. The problem is often that building out these implementations from scratch, and getting them right, is hard. In this talk, I’ll show how you can build cloud-based GraphQL back ends connecting to multiple databases (SQL and NoSQL), serverless functions, machine learning services, and microservices using TypeScript, AppSync, and AWS CDK – and do so in fewer lines of code than you’d expect. We’ll also look at how subscriptions, security, caching, and authentication are all handled, enabling you to build APIs that can simultaneously connect to tens of millions of clients at once to offer true real-time applications at scale. By the end of the talk, you should feel comfortable knowing that you can become a cloud engineer using an existing GraphQL skillset.
