Presented by: Daniel Oh Presented at the All Things Open 2021 Raleigh, NC, USA Raleigh Convention Center Abstract: Serverless functions are driving the fast adoption of DevOps development and deployment practices today. To successfully adopt serverless functions, developers must understand how serverless capabilities are specified using a combination of cloud computing, data infrastructure, and function-oriented programming. IT Ops teams also need to consider resource optimization (memory and CPU) and high-performance boot and first-response times in both development and production environments for faster time to market/service. What if we didn’t have to worry about all of that? In this session, I’ll be speaking about what kinds of open source projects and tools enable you to write a serverless function with superfast boot and response times and built-in resource optimization. Then, you’ll understand how these capabilities take you to advanced DevOps practices as well as business acceleration. Furthermore, developers can avoid the extra work of developing a function from scratch, optimizing the application, and deploying it to Kubernetes.
