Serverless architectures are the evolution of Platform as a Service (PaaS). With serverless, you give up specification of infrastructure concerns, instead the service allocates resources as required. Code (and servers) are only used when required, to handle specific requests and events. This simplifies deployment whilst reducing costs, since you only pay for what you use. AWS provides a range of services for building serverless architectures.

TypeScript is a type safe superset of JavaScript that allows us to write clean, simple code that runs anywhere JavaScript does. As a superset of JavaScript, all JavaScript skills and legacy code are readily reusable. Type safety brings many benefits, including catching bugs at compile time instead of run time, advanced static analysis tooling, powerful refactorings and better IDE experience.

TypeScript is an excellent choice for building serverless applications on AWS. We can implement our serverless functions in TypeScript to get all the benefits that brings, as well as excellent start times which is especially important for serverless. But serverless is not just AWS Lambda, we will have systems and services that use lots of AWS resources. We can also leverage TypeScript to write our deployment scripts in code via the AWS Cloud Development Kit (CDK). This gives us the powerful tooling of modern IDEs with static typing as well as the power of general purpose programming to implement and reuse patterns and remove redundancy. This is a step change compared to YAML Cloudformation templates.

In this course you'll move step by step to learn everything you need to know to build Serverless Applications in TypeScript on AWS.

You will need a good understanding of TypeScript and we can include additional TypeScript modules if required. We can work with your team to ensure we only teach what is necessary - teaching TypeScript from scratch or only the advanced topics. Then we'll work with the CDK to deploy your first Lambda and gradually introduce more and more services to build larger and larger applications using services like API Gateway, S3, CloudFront, DynamoDB and more. Along the way you'll learn how to test this code as well.

For a breakdown of what to expect in our training, check out our training overview page.

I really enjoyed the course overall, and there was a great mix of taught content as well as practical examples and exercises. The instructors were, as always, first class, incredibly knowledgeable, and always willing to take time to answer questions and help our understanding.

Great enthusiasm, lots of content covered in a short space of time. Very knowledgeable on all areas and answered any questions well, also great when helping everyone through the exercises. I got a great base understanding on react with typescript from having very little knowledge prior.

Fantastic course and trainer. Exercises are fantastic and documentation is great!
