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 provide you with multiple hosting plans 1. Consumption plan: The default and the cheapest plan. You are supposed to pay only when the code is running. 2. Premium plan: Better to choose when your app is running continuously. 3. Dedicated (App Service) plan: If you are already using your App Service for other applications, your Azure functions can run on the same App Service plan without paying any extra cost. |
| Supported Programming Languages | It supports different programming languages like JavaScript, Python, Java, C#, Go, PowerShell, Ruby, F#, etc. | Azure functions support different languages like Java, JavaScript, C#, Python, F#, PowerShell, F#, Ruby, Azure lacks Go, etc. |
| Programming Framework supports | Works based on the JSON objects. | Works based on the triggers and bindings. |
| In terms of performance and scalability | AWS Lambda is there in the market before Azure Functions and as per most of the users, Aws Lambda was performing well and can handle heavy workloads. | Azure functions also perform well and significantly improved in lesser time as compared to AWS lambda. Now, most of the users 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. | Here, you need to pay for the average memory consumption of executions. In terms of executions, you need to pay $0.000016/GB/ second. You can check out Azure Function Pricing for more information. |
| 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 are using the Consumption plan, then 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. |
