For developers seeking a serverless application development framework in Azure and Google Cloud, comparable to AWS SAM, Azure Functions and Cloud Functions are the alternatives to consider.

Azure Functions, a serverless compute service, enables developers to run event-driven code in a scalable and cost-effective manner. Similar to SAM, it offers a comparable development and deployment model, allowing developers to write code in popular languages like C#, Java, JavaScript, and Python. Azure Functions also supports multiple trigger types, such as HTTP requests, timers, and message queues, and seamlessly integrates with other Azure services like Cosmos DB, Event Grid, and Service Bus.

Cloud Functions is Google Cloud’s serverless compute platform that lets developers write code in languages such as JavaScript, Python, and Go. Like SAM and Azure Functions, Cloud Functions provides an event-driven code execution model, enabling developers to create code that can be triggered by events like HTTP requests, Cloud Storage changes, and Pub/Sub messages. Cloud Functions can be integrated with other Google Cloud services, including Cloud Firestore, Cloud Spanner, and Cloud Vision.

In summary, all three platforms – AWS SAM, Azure Functions, and Cloud Functions – provide similar serverless computing capabilities, including event-driven code execution, auto-scaling, and pay-per-use billing. However, differences in features and capabilities exist among the three, which makes it essential to evaluate each platform based on your specific needs and requirements.
