Ingress for Anthos—Multi-cluster Ingress and Global Service Load Balancing

Ingress for Anthos is a Google cloud-hosted multi-cluster ingress controller for Anthos GKE clusters. Ingress for Anthos supports deploying shared load balancing resources across clusters and across regions enabling users to use a same load balancer with an anycast IP for applications running in a multi-cluster and multi-region topology. In simpler terms this allows users to place multiple GKE clusters located in different regions under one LoadBalancer.

It’s a controller for the external HTTP(S) load balancer to provide ingress for traffic coming from the internet across one or more clusters by programming the external HTTP(S) load balancer using network endpoint groups (NEGs). NEGs are useful for Container native load balancing where each Container can be represented as endpoint to the load balancer. Taking advantage of GCP’s 100+ Points of Presence and global network, Ingress for Anthos leverage GCLB along with multiple Kubernetes Engine clusters running across regions around the world, to serve traffic from the closest cluster using a single anycast IP address.

What’s new in Kubernetes 1.16: Ephemeral containers for easy pod debugging, support for dual-stack network, new options for the scheduler and much more. These are the features that look more exciting to us for this release (ymmv): Ephemeral containers are a great way to debug running pods, as you can’t add regular containers to a pod after creation (you should use sysdig tools like kubectl capture or kubectl trace for that though!), but you can run ephemeral containers. Right now the steps to run an ephemeral container aren’t straightforward.

Introducing PodTopologySpread

Managing Pods distribution across a cluster is hard. The well-known Kubernetes features for Pod affinity and anti-affinity, allow some control of Pod placement in different topologies. However, these features only resolve part of Pods distribution use cases: either place unlimited Pods to a single topology, or disallow two Pods to co-locate in the same topology.

B-21 stealth bomber running Kubernetes for better SDLC experience

The new stealth U.S. Air Force B-21 bomber has taken yet another key technological step toward being ready for war, through integrated computer automation designed to streamline information, improve targeting and offer pilots organized warzone information in real-time. Air Force and Northrop Grumman developers recently completedan essential software-empowered process intended to bring greater levels of information processing, data management and new measures of computerized autonomy,according to published statements from Air Force Acquisition Executive Dr. William Roper. Through virtualization and software-hardware synergy, B-21 sensors, computers and electronics can better scale, deploy and streamline procedural functions such as checking avionics specifics, measuring altitude and speed and integrating otherwise disparate pools sensor information.
