Which runtimes does AWS Lambda support?

AWS Lambda is a serverless compute service that allows you to run code without worrying about the underlying infrastructure. One of the key features of AWS Lambda is its support for multiple programming languages through runtimes. In this article, we will explore which runtimes are compatible with AWS Lambda and how they work.

What are AWS Lambda Runtimes and how do they work?

These runtimes are environments that are pre-configured with a specific version of a programming language and its associated libraries. When you create a Lambda function, you specify the runtime that you want to use. When your Lambda function is invoked, AWS Lambda launches an execution environment that runs your code in the specified runtime. The runtime environment includes the language interpreter, any necessary libraries, and the AWS Lambda runtime interface. The runtime interface is a set of APIs that AWS Lambda uses to communicate with your function, such as passing input and output data.

Supported Runtimes

AWS Lambda currently supports the following runtimes:

1. Node.js: Node.js is a popular server-side JavaScript runtime that is commonly used for web applications.
2. Python: Python is a high-level programming language that is known for its readability and ease of use.
3. Java: Java is a widely-used programming language that is known for its stability and security.
4. Go: Go is a modern programming language that is designed for efficiency and scalability.
5. Ruby: Ruby is a dynamic, object-oriented programming language that is popular for web development.
6. .NET Core: .NET Core is a cross-platform, open-source framework for building applications with .NET.
7. PowerShell: PowerShell is a command-line shell and scripting language that is used primarily in Windows environments.

With AWS Lambda, you can use multiple programming languages to build serverless applications. With runtimes, you can write code in the language of your choice and AWS Lambda will automatically handle the rest, such as scaling and patching. AWS Lambda currently supports several runtimes, including Node.js, Python, Java, Go, Ruby, .NET Core, and PowerShell. By using runtimes in AWS Lambda, you can build scalable and cost-effective applications that meet the needs of your business.
