Deep Dive into Cilium Multi-cluster

Let’s review some of the use cases of connecting multiple Kubernetes clusters before we dive into the implementation details. High availability is the most obvious use case for most. This use case includes operating Kubernetes clusters in multiple regions or availability zones and runs the replicas of the same services in each cluster.

Inside Kubernetes RBAC

Kubernetes is a Container Orchestration Engine designed to host containerized applications on a set of nodes, commonly referred to as a cluster. Using a systems modeling approach, this series aims to advance the understanding of Kubernetes and its underlying concepts. The Kubernetes API is an Http API that provides Create/Read/Update/Delete access to query and modify the Kubernetes Object Store.

Back to Traefik 2.0

Back in 2015, a revolution was under way. We were moving from manual, handcrafted infrastructures, to container-based, industrial, and human-free platforms. In those dark ages of orchestration, edge traffic was remarkably difficult to manage.

Open Sourcing Peloton, Uber’s Unified Resource Scheduler

First introduced by Uber in November 2018, Peloton, a unified resource scheduler, manages resources across distinct workloads, combining separate compute clusters. Peloton is designed for web-scale companies like Uber with millions of containers and tens of thousands of nodes. Peloton features advanced resource management capabilities such as elastic resource sharing, hierarchical max-min fairness, resource overcommits, and workload preemption.

Using Machine Learning to Ensure the Capacity Safety of Individual Microservices

How a Kubernetes bug won’t let you expose a service over TCP and UDP on a same port

Ambassador and the Cloud Native Ecosystem—Part 1: Monitoring

In a Cloud Native world, microservices are running with ephemeral containers that are regularly deployed to multiple availability zones, regions, and even multiple clouds. As these cloud native applications become more complex, our supporting solutions like monitoring, have also had to become more complex. Today, more traditional monitoring responsibilities are being automated, and monitoring has become less human centric.

Envoy and the “Programmable Edge”: The Changing Role of Edge Proxies and Developer Experience

Introducing container observability with eBPF and Sysdig.

Today we’ve announced that we’ve officially added eBPF instrumentation to extend container observability with Sysdig monitoring, security and forensics solutions. eBPF – extended Berkeley Packet Filter – is a Linux-native in-kernel virtual machine that enables secure, low-overhead tracing for application performance and event observability and analysis. Don’t let the name fool you – eBPF delivers a lot more than network packet information (more on that below).
