This tutorial aims to provide a comprehensive comparison of different Cloud Function providers, highlighting their strengths and weaknesses. This will help you make an informed decision when choosing the best provider for your project.
By the end of this tutorial, you should understand:
This tutorial assumes you have a basic understanding of:
In this section, we will look at three major cloud function providers: Amazon Web Services (AWS) Lambda, Google Cloud Functions, and Microsoft Azure Functions.
AWS Lambda lets you run your code without provisioning or managing servers. You pay only for the compute time you consume.
Google Cloud Functions is a lightweight, event-based, asynchronous compute solution that allows you to create small, single-purpose functions that respond to cloud events without the need to manage a server or a runtime environment.
Azure Functions is a serverless compute service that lets you run event-triggered code without having to explicitly provision or manage infrastructure.
Here, we'll provide some basic "Hello, World!" examples for each provider.
def lambda_handler(event, context):
# Prints a message and the incoming event
print('Hello, AWS Lambda!')
print(event)
return 'Hello, AWS Lambda!'
def hello(request):
"""Responds to any HTTP request.
Args:
request (flask.Request): HTTP request object.
Returns:
The response text or any set of values that can be turned into a
Response object using
`make_response <http://flask.pocoo.org/docs/1.0/api/#flask.Flask.make_response>`.
"""
request_json = request.get_json()
if request.args and 'message' in request.args:
return 'Hello, Google Cloud Functions!'
elif request_json and 'message' in request_json:
return 'Hello, Google Cloud Functions!'
else:
return 'Hello, Google Cloud Functions!'
public static class Function1
{
[FunctionName("Function1")]
public static async Task<IActionResult> Run(
[HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequest req, ILogger log)
{
log.LogInformation("C# HTTP trigger function processed a request.");
return new OkObjectResult("Hello, Azure Functions!");
}
}
In this tutorial, we covered the key features, advantages, and disadvantages of AWS Lambda, Google Cloud Functions, and Microsoft Azure Functions. We also provided simple code examples for each provider.
To further your understanding, try deploying a function on each platform and testing it.
