# Lambda everywhere.
|
|
|
|
AWS Lambda introduced serverless computing to the masses. Wouldn't it be nice
|
|
if you could run the same Lambda functions on any platform, in any cloud?
|
|
Iron.io is proud to release a set of tools that allow just this. Package your
|
|
Lambda function in a Docker container and run it anywhere with an environment
|
|
similar to AWS Lambda.
|
|
|
|
Using a job scheduler such as IronFunctions, you can connect these functions to
|
|
webhooks and run them on-demand, at scale. You can also use a container
|
|
management system paired with a task queue to run these functions in
|
|
a self-contained, platform-independent manner.
|
|
|
|
## Use cases
|
|
|
|
Lambda functions are great for writing "worker" processes that perform some
|
|
simple, parallelizable task like image processing, ETL transformations,
|
|
asynchronous operations driven by Web APIs, or large batch processing.
|
|
|
|
All the benefits that containerization brings apply here. Our tools make it
|
|
easy to write containerized applications that will run anywhere without having
|
|
to fiddle with Docker and get the various runtimes set up. Instead you can just
|
|
write a simple function and have an "executable" ready to go.
|
|
|
|
## How does it work?
|
|
|
|
We provide base Docker images for the various runtimes that AWS Lambda
|
|
supports. The `fnctl` tool helps package up your Lambda function into
|
|
a Docker image layered on the base image. We provide a bootstrap script and
|
|
utilities that provide a AWS Lambda environment to your code. You can then run
|
|
the Docker image on any platform that supports Docker. This allows you to
|
|
easily move Lambda functions to any cloud provider, or host it yourself.
|
|
|
|
## Next steps
|
|
|
|
Write, package and run your Lambda functions with our [Getting started
|
|
guide](./getting-started.md). [Here is the environment](./environment.md) that
|
|
Lambda provides. `fnctl lambda` lists the commands to work with Lambda
|
|
functions locally.
|
|
|
|
You can [import](./import.md) existing Lambda functions hosted on Amazon!
|
|
The Docker environment required to run Lambda functions is described
|
|
[here](./docker.md).
|
|
|
|
Non-AWS Lambda functions can continue to interact with AWS services. [Working
|
|
with AWS](./aws.md) describes how to access AWS credentials, interact with
|
|
services like S3 and how to launch a Lambda function due a notification from
|
|
SNS.
