Hello, and welcome to the Getting Started with Serverless Computing Learning Path. Now, our agenda for this learning path looks a bit like this. We're going to start at ground zero with a what is serverless computing overview. We'll look forward to finding out a bit more about about what serverless is and what it isn't, and we'll look at the building blocks for what make up serverless computing scenarios. And we'll look at how people are using serverless functions in their design and implementations. Once we've got a good understanding of what serverless computing is, we're going to build our first REST API using the AWS API gateway service, and we're going to define a model for that API, we're going to define resources for the model, and then we're going to add methods that the client can use the access those resources, and then we're going to create our first serverless function using the AWS Lambda service. The learning objectives for this learning path are to be able to understand the concepts of serverless computing; to understand the building blocks, and some of the design considerations for the serverless application; understanding the RESTful API and being able to create an API gateway; recognize and and implement a serverless function. Now, there aren't a lot of prerequisites for this course. We assume that you have a basic understanding of what cloud computing is, so if you don't currently have that, I recommend doing our What is Cloud Computing course first. Okay, if you're ready, let's get started.
