This week we bring to you the Performance Superpowers with Enhanced BPF and present the improvements in the tool.

On the article of how GitHub has migrated their application responsible for github.com and api.github.com to run on K8S. How to automate docker Swarm cluster with terraform, how to calculate network addresses with ipcalc, how to backup correctly and quickly a critical Elasticsearch cluster and how to create swarm clusters that include both Windows and Linux environment.

On the section ‘Tools that we love!’, we bring dockerfilelint, an opinionated Dockerfile linter to review your Dockerfile against the best practices

Please, send us links, events, comic strip, DevOps job-related, etc., via @devopsweeknews.


Video of the week

This talk will explain the BPF enhancements, then discuss the new performance observability tools that are in use and being created, especially from the BPF compiler collection (bcc) open-source project. These tools provide new insights for file system and storage performance, CPU scheduler performance, TCP performance, and much more. This is a major turning point for Linux systems engineering, as custom advanced performance instrumentation can be used safely in production environments, powering a new generation of tools and visualizations.
