I've been helping lead BPF observability since 2014, and I'm a major contributor and maintainer for the front-ends. I'm also grateful that my fiancée, Deirdré Straughan, could find the time outside of her AWS job to do technical copy-edit. It was developed with the help of many members and leaders of the BPF community.

Since its introduction by AWS in 2014, AWS Lambda has revolutionized the compute space and boosted the entire serverless movement. This extension was built from scratch to take into account all we’ve learned and the special requirements for monitoring ephemeral, auto-scaling, micro VMs like AWS Lambda.

At Netflix, we've been using these technologies as they've been made available for instance types in the AWS EC2 cloud. The latest AWS hypervisor, Nitro, uses everything to provide a new hardware-assisted hypervisor that is easy to use and has near bare-metal performance. AWS called this [enhanced networking]. The first was c3.

These strange questions came to the fore back in 2014 when Netflix was switching services from CentOS Linux to Ubuntu, and I helped debug several weird performance issues including one I'll describe here. Aftermath I provided details to AWS and Canonical, and then moved onto the other performance issues as part of the migration.
