AWS recently announced the availability of EKS Anywhere, a deployment option for Amazon EKS that enables you to easily create and operate Kubernetes clusters on premises using VMware vSphere. As part of this, AWS picked Cilium as the built-in default for networking and security.
As users create their first EKS-A cluster, they will automatically have Cilium installed and benefit from the powers of eBPF.
AWS joins other cloud providers in picking Cilium as the networking and security layer. Managed Kubernetes offerings from Google Cloud, Alibaba, DigitalOcean, and several smaller platforms already leverage Cilium. With this latest announcement, three out of the big four cloud providers are now standardizing on Cilium for their cloud native networking and security needs.
Cilium is an open source project that provides networking, security, and observability for cloud native environments such as Kubernetes clusters and other modern compute infrastructure.
At the foundation of Cilium is a new Linux kernel technology called eBPF, which enables the dynamic insertion of powerful security, visibility, and networking control logic into the Linux kernel. eBPF is used to provide high-performance networking, multi-cluster routing, load balancing, transparent encryption, extensive network security capabilities, transparent observability, and much more.
