The Google Cloud API allows you to provide safe access to your backend services and helps you manage traffic. The service is fully managed by the Google Cloud Platform and allows developers to deal with APIs effectively.
We’ll be discussing everything you need to know about Google Cloud API Gateway, its features, how it can benefit your business, and much more. Let’s dive in.
Understanding Google Cloud API Gateway
Cloud API Gateway is a platform where you can oversee APIs for Google Cloud serverless back ends, including Cloud Run, App Engine, and Cloud Functions.
An API gateway acts as the front end of a microservice or API, allowing you to deliver services and manage requests.
It allows interactions between internal and external customers, data and services, and applications related to your organization. Other supported functions include analytics, rate limiting, and authentication.
Benefits of using an API Gateway
With the centralization of services being the primary benefit of any API gateway, here are a few other pros of using it;
Features of Google Cloud API Gateway
Here are some features of the Google API gateway that make the platform so unique.
With an understanding of API gateways and what Google cloud offers, you need to understand better how to get started.
Getting started with Google Cloud API Gateway
You need more than knowledge of Google Cloud API gateway to help you get started. Here are a few prerequisites that you must know to help you set up;
Here are two ways to set up your Google Cloud API gateway
1. Setting up using the console
Setting up a Google Cloud API gateway can be complex and hectic. However, following the steps mentioned below can make the setup using the console much easier;
Select your project by opening and navigating through the Google Cloud console.
Find “APIs and Services” in the left-hand menu, where you can create an API by selecting the “API Gateway” option.
You will be given multiple options to assist you in creating an API. Select the type of API you want to create: HTTP or gRPC.
Create a name of your choice that compliments your services. You must also choose a backend function such as Google Functions or Cloud runs afterward to ensure your API functions properly.
Authenticate and authorize your API program by selecting the appropriate options that suit your business model or API strategy.
Define your API using gRPC or OpenAPI specification.
Create a domain name for API services.
Deploy your API by clicking “Deploy API."
You can later test the functionality of your API gateway by using the endpoint URL.
2. Setting up using the command line
Another way of setting up a Google Cloud API gateway for your organization is by using the command line. Follow these steps to create and manage your API gateway easily;
You need to know the permissions required to set up an API gateway and whether you have them once you have them deploy the API gateway resources in your GCP.
The location you choose for your API gateway deployment can play a massive role in the latency and availability of your API. So, it would be best if you considered factors such as the location of your clients to provide the best services.
Authenticate and authorize your API gateway by configuring it using different tools. These include API keys and OAuth 2.0 and can help you manage your API services.
Use tools such as Google Cloud Console to test the deployment of your API gateway and ensure it is working as planned. Also, check for performance issues and failures by monitoring your API gateway instance monitoring tools or Cloud Logging.
Other steps might differ according to how you want to execute your API, but you can make your journey more accessible with these basic steps.
Working with Google Cloud API Gateway
Working with Google Cloud API gateways requires in-depth research and skills. Developers sometimes need to pay more attention to these requirements and find themselves in a difficult spot. Here are a few things you should do while working with Google API gateways;
1. Creating and deploying APIs
Google provides many API options, such as Google Cloud and gRPC APIs. An important thing to note is that each API can have a different impact depending on what your organization demands.
2. Configuring security and authentication
After finalizing a favorable authentication tool from many authentication methods, including OAuth 2.0 and API keys, you must configure it.
This requires you to create credentials and configure your API gateway to help you use these credentials.
3. Monitoring and logging with Google Cloud API Gateway
Google Cloud API Gateway helps you to monitor, analyze, and evaluate the performance of your API.
Best practices for Google Cloud API Gateway
You’d always want to maximize your outputs from the platform. This section discusses what you can do to help optimize everything.
This can include using OpenAPI specification to define your API, using API Gateway to manage your API’s lifecycle, and implementing security protocols.
1. Designing APIs for Google Cloud API Gateway
The following tips can help design APIs.
2. Scaling and performance optimization
For scaling and performance optimization, you can implement the following:
3. Cost optimization strategies
The third strategy you can implement is for optimizing costs.
Use cases and examples of Google Cloud API Gateway
By now you know how Google Cloud API Gateway works. It helps streamline your workflow and make it more comprehensive. We’ll be discussing some real-world examples along with their application in the section below.
For instance, the e-commerce platform Shopify makes use of secure and scalable e-commerce platform API to run its facilities.
Another example is Target, which uses a unified API for online and in-store experiences.
Advantages of using Google Cloud API Gateway over other alternatives
Google Cloud API Gateway is a great platform that helps you to deploy, manage, and secure your APIs without any problems. We’ve discussed the key points, the benefits the Gateway has, the advantages, and so much more.
The rise of Cloud Computing isn’t going to slow down any time soon. Thus, we can expect Google Cloud API Gateway to grow exponentially and become a very popular platform for developers.
