AWS lambda vs Azure functions
Let’s do a tabular comparison between Azure functions vs AWS lambda.
| Based On | AWS Lambda | Azure functions |
| Pricing tier or Hosting plan | Only one hosting plan in general. | Azure functions support languages like Java, JavaScript, C#, Python, F#, PowerShell, F#, Ruby, Azure lacks Go, etc. |
| Supported Programming Languages | AWS Lambda was in the market before Azure Functions, and as per most of the users, Aws Lambda was performing well and could handle heavy workloads. | It supports programming languages like JavaScript, Python, Java, C#, Go, PowerShell, Ruby, F#, etc. |
| Programming Framework supports | Works based on the JSON objects. | Works based on the triggers and bindings. |
| In terms of performance and scalability | In terms of performance and scalability, | Azure functions also perform well and significantly improve in less time than AWS lambda. Now, most users have also started using the Azure functions rapidly. |
| In terms of the Concurrency (maximum limit) | By default, the concurrency limit is 1000 invocations/region. | Can scale out at max 200 instances (Windows) and 100 instances (Linux). |
| In terms of Pricing | You need to pay full for provisioned memory capacity. In terms of executions, you need to pay $0.0000167/GB/ second. | AWS Lambda was in the market before Azure Functions, and as per most of the users, Aws Lambda was performing well and can handle heavy workloads. |
| In terms of Integration with HTTP | You need to pay a massive extra amount to use Amazon API Gateway for listening to the HTTP traffic. | Azure Function comes with in-built HTTP endpoint integration that you can use without paying any additional cost. |
| In terms of Cold Start | It takes hardly 1-2 seconds to win the race here. | If you use the Consumption plan, the cold start will take 10 seconds approximately. Here, you have to upgrade to the higher plans to minimize the cold start time, but anyway, you have to pay extra amounts for higher plans. |
