Kubernetes
Kubernetes (abbreviated K8s) is an open-source container orchestration platform originally designed by Google and donated to the Cloud Native Computing Foundation (CNCF) for maintenance. It automates the deployment, scaling, and management of containerized applications, supporting container scheduling and load balancing across multi-host clusters. Core capabilities include service discovery, rolling updates, and automatic recovery, making it a foundational infrastructure component for cloud-native application architectures.

The SIE self-hosted version is Apache 2.0 licensed, runs in the user's own VPC, is deployed to AWS, GCP, or Azure via Terraform and Helm, and achieves scale-to-zero between tasks on Kubernetes via KEDA.
KEDA is a CNCF graduated project that drives the Kubernetes Horizontal Pod Autoscaler by consuming external event sources (such as message queue depth or cron expressions), making up for the limitation that native HPA can only scale based on CPU/memory metrics.
Kubernetes itself is an orchestration system for general-purpose containers, and its default scheduler takes CPU and memory as core resource dimensions; support for heterogeneous accelerators such as GPUs requires extension via the Device Plugin mechanism.
Run:ai was initially known for helping enterprises efficiently schedule GPU resources on Kubernetes, and after being acquired by NVIDIA its positioning shifted toward being the hub of the AI factory.
Run:ai introduces queues, quotas, priorities, and preemption mechanisms on top of Kubernetes, turning GPUs from exclusive devices into pooled resources that can be shared and scheduled by multiple teams.
One CGI interview of Manish's ended after only five minutes, because he knew almost nothing when the interviewer asked about Kubernetes architecture.
Manish advises people transitioning into DevOps/SRE to tie together knowledge points such as Linux, Shell, AWS, Terraform, Docker, Kubernetes, CI/CD, Prometheus, Grafana, and Python through one complete end-to-end project, and the project can take three to six months to complete.
In the livestream, the agent used Codex's Chrome connector to access web pages, inspect elements, extract an API key from 1Password, and use these credentials to SSH into a Kubernetes cluster to run kubectl get pods, all without human intervention.
The three-layer defense principle is: reject bad traffic as early and as cheaply as possible, and assume that every layer will occasionally miss. Blocking at the edge costs nothing, blocking at the load balancer costs little, requests reaching the Pod cost the most, and the runtime layer is the last line of defense.
The Kubernetes community's `ingress-nginx` controller has been retired, and the same approach applies to Gateway API implementations (such as Envoy Gateway) or any L7 load balancer.

80%VerifiedKubernetes was open-sourced by Google in 2014 and has become the de facto standard for container orchestration.
75%VerifiedBoth Kubernetes and TensorFlow adopt the Apache 2.0 open-source license.
70%VerifiedYAML has become the de facto standard configuration language in the DevOps domain and is widely adopted by Kubernetes, Ansible, and GitHub Actions.
70%VerifiedKata Containers combines the hardware isolation of lightweight virtual machines with the ease of use of the OCI container standard.
65%VerifiedThe OCI standard in the containerization field allows Docker containers to run on any compatible runtime, and Kubernetes' CRI allows different container runtimes to be interchangeable.
65%VerifiedKubernetes is a container orchestration platform open-sourced by Google and has become the de facto standard for cloud-native deployment; its HPA can dynamically scale inference instances up or down based on request queue length.
65%VerifiedThrough the MultiServerMCPClient provided by the langchain-mcp-adapters package, developers can connect to multiple MCP services at once.
65%VerifiedKubernetes adopts a control plane and data plane separation architecture, including etcd for storing desired state, API Server as the entry point for state changes, Controller Manager running control loops, and Scheduler for scheduling Pods.
65%VerifiedThe three basic Kubernetes Service types are ClusterIP, NodePort, and LoadBalancer.
65%VerifiedKubernetes's NodePort mode forwards external traffic to Pods inside the cluster by opening a fixed port (in the range 30000–32767) on every node in the cluster.
