Istio a service mesh

Istio is a service mesh, and it's a cool new project from Google, IBM, Lyft and others. This talk describes at a high level how Istio works as a sidecar, and how it works great with Weave Cloud, which provides visualization to understand what's going on when you deploy Istio, and long-term Prometheus metrics storage with its built-in Prometheus service.

This document introduces Virtual Kubelet, which extends the Kubernetes API to serverless container platforms. It treats the concept of pods and nodes abstractly, allowing pods to run on platforms like ACI and Fargate. Virtual Kubelet implements a provider interface to manage the pod lifecycle on these platforms. It also allows hybrid use cases like running traditional and serverless pods together. The document demonstrates how Virtual Kubelet can schedule pods to ACI from an AKS cluster and to Nomad from a Kubernetes cluster.

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.

Kubernetes has two simple but powerful network concepts: every Pod is connected to the same network, and Services let you talk to a Pod by name. Bryan will take you through how these concepts are implemented - Pod Networks via the Container Network Interface (CNI), Service Discovery via kube-dns and Service virtual IPs, then on to how Services are exposed to the rest of the world.

The document provides an overview of microservices and service meshes, and uses Istio as an example service mesh implementation. It discusses how Istio allows microservices to be developed independently while providing capabilities like discovery, load balancing, resilience, metrics and tracing through lightweight proxies. The document then demonstrates what happens at each step of a request's lifecycle as it travels through an application protected by Istio's service mesh. Specifically, it shows how Istio components like Pilot, Envoy, Mixer and Citadel work together to provide control, observability and security for microservices.

Learn the differences between Envoy, Istio, Conduit, Linkerd and other service meshes and their components. Watch the recording including demo at: https://info.mirantis.com/service-mesh-webinar

This document discusses Cloud Native Identity Management using SPIFFE (Secure Production Identity Framework for Everyone) and SPIRE (SPIFFE Runtime Environment). It provides an overview of SPIFFE and SPIRE, including how they address identity management challenges in cloud-native environments. It then summarizes how SPIRE implements the SPIFFE specifications through a node attestation and workload attestation process where a SPIRE agent authenticates to a server, retrieves selectors to verify workloads, and issues signed identity documents when a workload matches the selectors.

Should you choose a microservices architecture over a monolith? What are the pros and cons in reality.

Slide was presented at Dr. Dobb's Conference in Bangalore. Talks about Openstack Introduction in general Projects under Openstack. Contributing to Openstack. This was presented jointly by CB Ananth and Rahul at Dr. Dobb's Conference Bangalore on 12th Apr 2014.

This presentation outlines the benefits of implementing a Microservice over a monolithic architecture.

This document summarizes the evolution of a company's cloud native applications on a Kubernetes stack from 2018 to present. It started with 1000+ Kubernetes nodes hosting 18K pods and handling 650 requests/second across 2 cloud providers. Over the years, the company expanded its use of Kubernetes, added more applications, services, and tools for monitoring, logging, ingress control, and more. It now aims to improve developer experience, continue migrating infrastructure services to Kubernetes, and implement its first FinOps tool.
