Im definitely biased but Nodejs is probably the best one on this list. Benefits of Lambda over EC2 Instances No Servers to manage.
Swift On Aws Lambda Performs Like Node And Python Using Swift Sprinter Aws Lambda Language Challenge Lambda
Which AWS Lambda programming language should you use.

Aws lambda languages. Strong and supportive community. They released open-source custom runtimes for. While observing language runtimes for AWS Lambda the functions monitored for Nodejs and Python were at 5253 and 3584 percentages while invocations monitored in both languages were at 4496 and 2101 percentages.
In terms of choosing the language for your project the following factors are important considerations. Because of the popularity and demand for AWS Lambda support for additional languages and newer languages versions quickly followed. But Java has a good performance when the function is warmed up.
This means that you can take advantage of new language features and performance improvements in these runtimes just by reviewing the compatibility of these new versions and migrating your function code over. For a function defined as a container image you choose a runtime and the Linux distribution when you create the container image. Ruby is a relatively new addition to the AWS Lambda roaster but there is a lot of interest around it.
In essence it is those languages. However there are lots of other programming languages out there that you may want to use in your Lambda function to migrate to AWS Lambda existing applications currently deployed on. But if performance is the driving consideration for your application the performance characteristics of each language are what you might expect on Lambda as you would in another runtime environment.
What languages does AWS Lambda support. AWS Lambda is a serverless compute service that lets you run your code without worrying about provisioning or managing any server. Official Lambda supported languages.
Thats the case of NodeJS and Python. Just upload your code on Lambda and it will run your code even scale the infrastructure with high availability. When considering different versions and maturity of documentation AWS Lambda does provide the broadest set of supported programming languages.
AWS Lambda is sometimes referred to as a function-as-a-service FaaS AWS Lambda executes code whenever the function is triggered and no Amazon Elastic Compute Cloud Amazon EC2 instances need to be spun up in your infrastructure. Its also known that interpreted languages and compiled languages have a better performance in terms of cold start. As an addition to all the available runtimes in AWS Lambda AWS announced Custom Runtimes at ReInvent 2018.
You can also use the Ruby Go andNET Core runtimes. As of right now there are several runtime versions of Nodejs Python and Java. AWS provides two options.
What languages does AWS Lambda support. At the moment of this writing AWS Lambda natively supports Java Go PowerShell Nodejs C Python and Ruby. It thus makes it simple to use.
NewRelic observed that functions with substantial volume run on versions 610 in Nodejs and Python 27 and even older versions. Its known that programming languages based on JVM like Java have a higher cold start. Java has been in service for decades and is to this day a reliable option when choosing the backbone of your.
Please read our documentation on using Nodejs Python Java Ruby C Go and PowerShell. The AWS Lambda cold start issue has been examined in a previous post. Its clean code improves AWS Lambda performance.
AWS Lambda natively supports Java Go PowerShell Nodejs C Python and Ruby code and provides a Runtime API which allows you to use any additional programming languages to author your functions. The compiled languages Java and NET incur the largest initial startup cost for a containers first invocation but show the best performance for subsequent invocations. In the last week or so AWS also launched three new supported runtime versions for AWS Lambda.
I know it has its downfalls but. Consequently AWS was chosen as the platform for the experiment. You can run your application or backend service using AWS Lambda with zero administration.
You can write Lambda functions in your favorite language Nodejs Python Go Java and more and use both serverless and container tools such as AWS SAM or Docker CLI to build test and deploy your functions. AWS Lambda language benchmarks. Lambda supports multiple languages through the use of runtimes.
Nodejs 12 Python 38 and Java 11. The language has unique modules that allow the addition of new elements of class hierarchy at runtime. Underlying the choice of programming languages there are different container environments available.
To change the runtime you create a new container image.
