Episode description

Bret and Nirmal are joined by Ken Collins, AWS Serverless Hero and Principal Engineer at Custom Ink to discuss all things Lambda and to dig into the details of running containers in serverless.

Ken and I have known each other for probably 15 years in the local tech scene here in coastal Virginia. And I've always respected him for being a leader in that community, always wanting to talk at a meetup or help in some way.

So when he reached out wanting to talk about his company using containers on AWS Lambda, it was an easy sell for me because I knew it would be a great show. And then I learned some of the updates Lambda has had over the years, particularly when it comes to container workflows.

We had some great audience questions and no shortage of topics around using modern Lambda and serverless.

Live recording of the complete show from September 7, 2023 is on YouTube (Ep. #233).
