We have covered Facebook's BPF-based load balancer with DDoS protection in a previous blog post. This post provides further details on Facebook's BPF use by covering Anant Deepak's talk at the BPF/networking microconference on Facebook's BPF-based edge firewall running in production.
We are excited to announce the Cilium 1.3 release. The release introduces several new features. The major highlight of the release is the addition of Go extensions for Envoy as well as Cassandra and Memcached protocol parsers with policy enforcement capability, both implemented as Envoy Go extension.
Cilium provides API-aware network security for cloud-native applications. Here's a How-To guide to get you going easily with Kubernetes and Cilium on Ubuntu 18.04 LTS.
Kubernetes clusters are used by multiple tenants to run their containerized workloads. Often, the tenant workloads are mapped to namespaces and strict access control is required for inter-namespace communications. The access control could be needed for separation of concerns such as monitoring namespace vs application namespace; for compliance such as PCI vs non-PCI workloads; or to meet requirements of serving different end customers such as workloads serving Pepsi vs Coke. In this post, we will look at namespace based segmentation of traffic along with examples of allowing specific inter-namespace communications.
We are excited to announce the Cilium 1.2 release. The release introduces several new features addressing the top asks from Cilium users and community members. One of the most exciting features is the introduction of security policies based on DNS names to secure access to external services outside of the cluster. Another top ask was to introduce the ability to connect and secure multiple Kubernetes clusters. We are introducing ClusterMesh as an alpha level feature to address this ask. It allows to connect and secure pods running in different Kubernetes clusters. Equally important is the Kube-router integration with Cilium. The effort led by the team from DigitalOcean enables to combine BGP networking provided by kube-router with BPF based security and load-balancing from Cilium. As usual, a big shout out to the entire community of Cilium developers. The total number of contributors has grown to 85 and 579 commits have been contributed in the time period between 1.1 and 1.2.
Istio 1.0 was released last week. From the Cilium community, we would like to congratulate all Istio contributors for this massive effort. We have been fortunate to participate in the community by contributing to Istio and by helping several users moving towards production with Istio and Cilium.
In Kubernetes deployments, Prometheus is a popular monitoring system and time-series database for storing health and performance metrics of all the components. Equally popular is Grafana for plotting the metrics. In this post, we will provide steps to setup Prometheus and Grafana for understanding important Cilium metrics related to the security and health of service interactions in a Kubernetes cluster.
Elasticsearch is a dominanting open source platform for storing and analyzing all different types of data ranging from application logs, to user payment transactions and network audit logs.
