Compare AWS-lambda, Azure functions and Google Cloud Function

Compare AWS-Lambda, Azure Functions and Google Cloud Functions

  1. Supported Languages
    AWS lambda- Node.js, Python, Java, C# (.net core)
    Azure Function - Node.js, Python, PHP, F#, C#, batch, bash
    Google Cloud Functions Node.js

  2. Maximum execution time per request
    AWS lambda- 300 seconds (5 minutes)
    Azure Function - 300 seconds (5 minutes)
    Google Cloud Functions 540 sec (9 minutes)

  3. Log Management
    AWS lambda- Cloud watch
    Azure Function - Azure Storage
    Google Cloud Functions Cloud Logging

  4. Scalability & availability
    AWS lambda- Automatic scaling 
    Azure Function -Automatic scaling 
    Google Cloud Functions Automatic scaling 
  5. HTTP End point
    AWS lambda- AWS API Gateway 
    Azure Function -HTTP Trigger
    Google Cloud Functions HTTP Trigger 

  6. Pricing
    Note: These are per-call fees. Charging for CPU and RAM time is common, generally exceeds the per-call fee, and should be considered.
    AWS lambda-$0.20/1M executions 
    Azure Function-$0.20/1M executions 
    Google Cloud Functions $0.40/M execution, no extra for HTTP calls pricing details

  7. Function Limit
    AWS lambda-Unlimited functions
    Azure Function-Unlimited functions
    Google Cloud Functions 1,000 per project  

  8. Concurrent executions
    AWS lambda-100 parallel executions per account per region but users can increase it
    Azure Function -No limit
    Google Cloud Functions HTTP no limit, 1,000 non-HTTP 

  9. Deployments
    AWS lambda-Zip, AWS-S3 or edit code inline 
    Azure Function-Anything an Azure WebApp can handle: FTP(S), KUDU, Web Deploy, One Drive\DropBox, Git\Local Git\TFS\etc, Visual Studio\XCode\Eclipse\etc, PowerShell\Cli\Probably all the SDK's
    Google Cloud Functions CLI, ZIP upload, inline web editor, Cloud Storage or Cloud Source Repositories
