If you are building a microservice, you need to find a way to expose it. Suppose you are working with Cloud Functions or with Cloud Run. If you want to expose them using a structured and secure API, you should consider using Cloud API Gateway. Cloud API Gateway is a fully managed, easy-to-use, and secure Google service that allows you to create an API for the workload you need to expose. It offers reduced complexity because it lets you define the API using the Swagger OpenAPI 2.0 standard. Following this standard, you would define the specifics about the method of exposing your workloads, such as the path and the protocol.

In this lab, you will create a Cloud Function, and you will create an API with Cloud API Gateway to expose it.

Learning Objectives

Upon completion of this lab, you will be able to:

• Create an API definition following the OpenAPI 2.0 standard
• Expose a workload with an API through Cloud API Gateway

Intended Audience

This lab is intended for:

• Google Cloud Professional Cloud Developer (PCD) candidates
• Software engineers that need to expose workloads hosted on Google Cloud
• Cloud Architects who want to understand how to handle and expose multiple workloads in a structured way

Prerequisites

No prerequisites are required.
