CodeTalk Episode 4: Key Serverless Concepts for Developers

As new abstractions crumble the wall between dev and ops, the modern developer is increasingly tasked to not only design the application, but also understand how it will perform in production. Serverless has emerged as one of the most intriguing new directions for how business logic and functions are managed in the Cloud. As a community, we've been wrestling with serverless definitions and use case examples—so, in this episode of CodeTalk we speak with the original creator of the Apache OpenWhisk prototype (and part of the core IBM Cloud Functions Team at IBM), Rodric Rabbah. Rabbah breaks down some key concepts that will help any developer better qualify serverless and answer the whens and whys of using it.

Key Discussion Points:

• Early days OpenWhisk—the vision and goals from one of the project's creators.
• Where serverless fits into the containers and Kubernetes world.
• The evolution of how the serverless model handles "state" and memory.
• Design considerations for functions themselves—what is the right size/responsibility of a function?
• How does composition of functions work, and what are the main trade-offs and concerns?
• If you're developing in this model, what does troubleshooting and debugging of serverless look like?
