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.

Python is a dynamic, user-friendly and powerful language with a huge community. It is an excellent choice for building serverless applications on AWS. There are many advantages to writing AWS Lambda code in Python, not least the rapid startup that is vital for serverless functions. But serverless is not just AWS Lambda, we will have systems and services that use lots of AWS resources. We can also leverage Python to write our deployment scripts in code via the AWS Cloud Development Kit (CDK). This allows us to leverage the power of a general purpose programming language 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 Python on AWS.

You will need a good understanding of Python, so we can include additional Python modules if required. We can work with your team to ensure we only teach what is necessary - from first principles to 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.

Delegates will need to fully understand the Python language. However, this can be included within the delivery. We can teach from beginner to advanced level and can tailor the course based on your prior knowledge and experience. An active AWS account is required (although one can be provided for an additional fee).
