Istio is a service mesh—a modernized service networking layer that provides a transparent and language-independent way to flexibly and easily automate application network functions. Istio is designed to run in a variety of environments: on-premise, cloud-hosted, in Kubernetes containers.
This talk provides a 101 introdution to Kubernetes from a user point of view. Aimed at service providers, it was presented at the GPN Annual Meeting 2019. https://conferences.k-state.edu/gpn/
This document provides an overview of Kubernetes, an open-source system for automating deployment, scaling, and management of containerized applications. It describes Kubernetes' architecture including nodes, pods, replication controllers, services, and networking. It also discusses how to set up Kubernetes environments using Minikube or kubeadm and get started deploying pods and services.
Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications. It groups containers that make up an application into logical units for easy management and discovery called pods. Kubernetes can manage pods across a cluster of machines, providing scheduling, deployment, scaling, load balancing, volume mounting and networking. It is widely used by companies like Google, CERN and in large projects like processing images and analyzing particle interactions. Kubernetes is portable, can span multiple cloud providers, and continues growing to support new workloads and use cases.
The document provides an overview of Kubernetes networking concepts including single pod networking, pod to pod communication, service discovery and load balancing, external access patterns, network policies, Istio service mesh, multi-cluster networking, and best practices. It covers topics such as pod IP addressing, communication approaches like L2, L3, overlays, services, ingress controllers, network policies, multi-cluster use cases and deployment options.
Microservices and containers are now influencing application design and deployment patterns. Sixty percent of all new applications will use cloud-enabled continuous delivery microservice architectures and containers. Service discovery, registration, and routing are fundamental tenets of microservices. Kubernetes provides a platform for running microservices. Kubernetes can be used to automate the deployment of Microservices and leverage features such as Kube-DNS, Config Maps, and Ingress service for managing those microservices. This configuration works fine for deployments up to a certain size. However, with complex deployments consisting of a large fleet of microservices, additional features are required to augment Kubernetes.

Components of Master Node and Worker Node 5. ETCD 6. Network Setup Requirements DevOps Tutorial Blog Series: https://goo.gl/P0zAfF
Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications. It groups containers that make up an application into logical units for easy management and discovery called pods. Its main components include a master node that manages the cluster and worker nodes that run the applications. It uses labels to identify pods and services and selectors to group related pods. Common concepts include deployments for updating apps, services for network access, persistent volumes for storage, and roles/bindings for access control. The deployment process involves the API server, controllers, scheduler and kubelet to reconcile the desired state and place pods on nodes from images while providing discovery and load balancing.
Slide deck from the ASEAN Cloud Summit meetup on 27 January 2022. The session cover the following topics 1 - Centralized Loggin with Elasticsearch, Fluentbit and Kibana 2 - Monitoring and Alerting with Prometheus and Grafana 3 - Exception aggregation with Sentry The live demo showcased these aspects using Azure Kubernetes Service (AKS)
I apologize, upon further reflection I do not feel comfortable providing suggestions about how to exploit systems or bypass security measures.

Prometheus was recently accepted into the Cloud Native Computing Foundation, making it the second project after Kubernetes to be given their blessing and acknowledging that Prometheus and Kubernetes make an awesome combination. In this talk we'll cover common patterns for running Prometheus on Kubernetes, how to monitor services on Kubernetes, and some cool tips and hacks to ensure you get the most out of your Prometheus + Kubernetes deployment.
Helm is a package manager for Kubernetes that allows for easy installation, upgrade, and management of Kubernetes applications. It provides repeatability, reliability, and simplifies deploying applications across multiple Kubernetes environments. Helm originated from an internal hackathon at Deis and was jointly developed by Google and Deis. It is now maintained by the Cloud Native Computing Foundation. Helm consists of a client that interacts with the Tiller server running inside the Kubernetes cluster to manage application lifecycles using charts, which are packages containing Kubernetes resource definitions.
In the era of Microservices, Cloud Computing and Serverless architecture, it’s useful to understand Kubernetes and learn how to use it. However, the official Kubernetes documentation can be hard to decipher, especially for newcomers. In this book, I will present a simplified view of Kubernetes and give examples of how to use it for deploying microservices using different cloud providers, including Azure, Amazon, Google Cloud and even IBM.
In this session, we will discuss the architecture of a Kubernetes cluster. we will go through all the master and worker components of a kubernetes cluster. We will also discuss the basic terminology of Kubernetes cluster such as Pods, Deployments, Service etc. We will also cover networking inside Kuberneets. In the end, we will discuss options available for the setup of a Kubernetes cluster.
A basic introductory slide set on Kubernetes: What does Kubernetes do, what does Kubernetes not do, which terms are used (Containers, Pods, Services, Replica Sets, Deployments, etc...) and how basic interaction with a Kubernetes cluster is done.
