How to deploy 4 lambdas in typescript using a code pipeline ?

Question

My customer is looking to deploy the app infra via a code pipeline which has the source, lint, compile, build, package and deploy stages. The lambda is in typescript and there are 4 lambdas which should be deployed for this app. Is there a need to have a different codepipeline for each lambda deployment or can I deploy all the lambdas in a single code pipeline. If there is a single pipeline, how will the app code linting, building, compiling and packaging happen for all the 4 lambdas ? Is it going to be in parallel? If yes, then would there 4 parallel runs of lint, compile and so on. Is there any reference architecture ?

Answer

Hello,

You can use [AWS SAM](https://aws.amazon.com/serverless/sam/) to deploy an application which could include 1 or more Lambda functions. With AWS SAM, you can deploy multiple functions in the same application easily.

Here you can find more information on who to build and deploy resources using [AWS CodePipeline](https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/deploying-using-codepipeline.html) with AWS SAM.

But we highly recommend to analyze if those functions must be deployed in 1 or multiple pipelines following the Well Architected Framework.

Regards.
