 eCHO news is your bi-weekly wrap up of all things eBPF and Cilium. If you want to keep up on the latest in cloud native networking, observability, and security this is your quelle

17th October 2023

 

In case you missed the news, Cilium is now a graduated project in CNCF. Check out the full press release or the highlights below to see some of the wonderful things the community had to say about achieving this milestone. Beyond these quotes, going through this whole process has really demonstrated to me just how much the community loves Cilium. My favorite vanity metric is that over 800 people went to the CNCF GitHub and put a πŸ‘, πŸŽ‰, πŸš€, or ❀️ on the proposal to make Cilium a graduated project.

 

As Tim Hockin said "From the earliest days of Kubernetes, we knew that a thriving ecosystem was a critical ingredient, and Cilium is perhaps the most visible demonstration of this." Thank you to all of the contributors, community members, adopters, and supporters that helped make graduation possible. I feel lucky every day I get to work with you. As always still more work to do though so let's 🐝 gin!

The Graduation

Cloud Native Computing Foundation Announces Cilium Graduation

The official press release from CNCF

 

Cilium leaves incubator, gets the nod from Cloud Native Computing Foundation - The Register

"From the earliest days of Kubernetes, we knew that a thriving ecosystem was a critical ingredient, and Cilium is perhaps the most visible demonstration of this. Cilium taps into the power and excitement of eBPF to super-charge Kubernetes networking"

 

Cilium CNCF Graduation Could Mean Better Observability, Security with eBPF - TNS

"Cilium offers much more than just network capabilities β€” you can start with basic connectivity, and it becomes more useful as your project grows"

 

CNCF Graduates Cilium Networking Software Project - Cloud Native Now

"Those capabilities ultimately should make it simpler for IT teams to programmatically converge network and security operations within the context of a DevOps workflow"

 

CNCF announces graduation of Cilium project - ITOpsTimes

"Cilium and the modern eBPF stack will help shape the future of cloud native networking, observability, and security because of eBPF’s visibility into the kernel and ability to oversee and control the entire system"

 

Container networking engine Cilium graduates from CNCF incubation - SiliconAngle

"Cilium’s graduation highlights its evolution from a simple CNI to a complete networking, observability, and security solution that prepares platforms and organizations for the next steps on their cloud native journey"

 

Cilium Graduates From CNCF Incubator - TFIR

"Cilium has demonstrated really impressive growth in its nearly two years in the Incubator, and we’re excited to watch as the ecosystem continues to push the benefits of eBPF even further"

 

Cilium Graduates at the CNCF - Isovalent

"As the first networking plugin to reach Graduation – and with every major cloud provider choosing Cilium for their Kubernetes platform – Cilium really is the default choice for Kubernetes connectivity"

The Ecosystem

Cilium vs Calico

"In conclusion, I found that Cilium a superior networking plugin for Kubernetes than Calico in terms of performance, functionality, and flexibility"

 

Platform Engineering Trends in Cloud Native: Q&A With Thomas Graf

"A modern cloud-native networking layer looks more like a messaging bus than a network to developers but without requiring your applications to change in any way and while continuing to the strong security and performance requirements of a typical enterprise network."

The Tweet of the Week

Cilium is the thing you want to run with your K8. I played with it some time. eBPF is just too good to skip it!

As always, if you’ve seen a blog post, a tool, or anything else eBPF or Cilium related that you think the rest of the community should hear about, send them my way. You can either hit reply or join the #echo-news channel on Cilium Slack. You can also find all of the past episodes on the website.
