This document discusses continuous delivery fundamentals and how serverless platforms can help realize them. It covers topics like automated software releases through pipelines, building quality into products from the start, and how serverless handles infrastructure concerns so developers can focus on code. Examples are provided of using AWS Lambda, API Gateway, S3, Route53, CloudFormation, CodePipeline and other services to implement continuous delivery of serverless applications.

Delivery?

6. Continuous =
Every change triggers the feedback process
Continuous Delivery Fundamentals
“If it hurts, do it more often!”
-Martin Fowler, ThoughtWorks

7. Continuous Delivery Fundamentals
Quality = Build it into the product
“Cease dependence on mass inspection to achieve quality.
Improve the process and build quality into the product in the first
place”
-W. Edwards Deming

8. Continuous Delivery Fundamentals
Automated = Releasing software should be
repeatable and reliable
“Let’s make deployments a boring, push-button
experience!”
-Anonymous Lazy Developer

10. Serverless?

12. Just show up with some code and the platform handles:
● Operating System – no need to select, secure, configure,
administer or patch the OS
● Servers – no cost risk of over-provisioning and no
performance risk of under-provisioning
● Capacity – no need to monitor utilization and scale capacity
based on load
● High Availability – compute resources are available across
multiple AZs
