 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

2nd January 2024

 

With Dan's new blog post about parsing HTTP with eBPF, I was going to kick off the year talking about the new things that will be unlocked with eBPF in the coming year, but Cisco's intent to acquire Isovalent also broke just before the holiday break and it would feel wrong to not discuss that too. I think they also compliment each other perfectly.

 

Cilium has already become the stock networking data plane for all major cloud providers, most Kubernetes distributions, and a laundry list of companies large and small. Having the networking giant Cisco acquire the team that founded Cilium only further cements Cilium's status as the de facto standard for cloud native networking. In Thomas's words "Cisco is fully committed to double down on open source, Cilium, CNCF, and all the projects we have been involved with. This was obviously criteria #1 to even talk."

 

With Cilium as the standard, Cisco doubling down, and new capabilities coming to eBPF like HTTP parsing, I think this will be the most exciting year yet for the community. Want to catch up on everything that happened last year? Check out the Cilium Annual Report or continue reading this newsletter. Let's 🐝 gin!
