  **Deploy with containers**
  
  If you need a custom runtime that is not provided by AWS, you can create and deploy a custom 
  
  container image. AWS provides base images preloaded with a language runtime and other 
  
  components that are required to run the image on Lambda. AWS provides a Dockerﬁle for each of 
  
  the base images to help with building your container image. 
  
  Custom containers are one way you might experiment with lift and shift of existing code to 
  
  Lambda runtimes. If you do this, consider the architectural diﬀerences between always running 
  
  containers, versus on demand nature of Lambda functions.
