Istio Service Mesh

The document discusses Istio, an open source service mesh that provides traffic management, service migration and monitoring for microservices. It provides an overview of key Istio concepts like the control plane, data plane and components like Envoy, Pilot and Mixer. It also includes steps to install Istio on GKE and deploy a sample Bookinfo application to demonstrate traffic routing and load balancing capabilities.

While service meshes may be the next "big thing" in microservices, the concept isn't new. Classical SOA attempted to implement similar technology for abstracting and managing all aspects of service-to-service communication, and this was often realized as the much-maligned Enterprise Service Bus (ESB). Several years ago similar technology emerged from the microservice innovators, including Airbnb (SmartStack for service discovery), Netflix (Prana integration sidecars), and Twitter (Finagle for extensible RPC), and these technologies have now converged into the service meshes we are currently seeing being deployed. In this webcast, Daniel Bryant shows you what service meshes are, why they're well-suited for microservice deployments, and how best to use a service mesh when you're deploying microservices. This webcast begins with a brief history of the development of service meshes. From there, you'll learn about some of the currently available implementations that are targeting microservice deployments, such as Istio (Envoy), Linkerd, NGINX Plus, and Traefik. Attendees will walk away with a high-level overview of the concept, tools for deciding when best to use a service mesh, and a getting started guide if they decide this technology is the right fit for their organization.

Introduce Service Mesh and istio to implement microservices more elegant way at Oracle Developer Meetup in Korea

There is a lot of talk now around the term Service Mesh. The hype is high and the promise is real. The problem is that there is not really a good definition of what service mesh really is. In this talk we are going to review the problem service meshes are trying to solve, name the core components that make up a service mesh, and discuss the benefits an organization can receive by implementing this new technology.

Modern application architecture is shifting from monolith to microservices: componentized, containerized, and orchestrated with systems like Kubernetes, Mesos, and Docker Swarm. While this environment is resilient to many failures of both hardware and software, applications require more than this to be truly resilient. In this talk, we introduce the notion of a "service mesh": a userspace infrastructure layer designed to manage service-to-service communication in microservice applications, including handling partial failures and unexpected load, while reducing tail latencies and degrading gracefully in the presence of component failure.

Container and OpenStack clouds often co-exist in data centers. Monitoring both environments require views into the underlay and overlay infrastructure, but infrastructure monitoring alone is no longer sufficient and needs to be paired with security policy views as containers and microservices are constantly reshaping data center traffic and flow patterns. A visualization GUI that correlates containers and VMs with security policy views provide a powerful tool for any operations team to detect security flow violations in real-time. Enterprises and cloud providers are adopting visualization and monitoring platforms in addition to OpenStack Horizon to keep their infrastructure running with 100% uptime. New tools that help with proactive remediation of issues are being deployed to quickly bring back the system to healthy conditions.

SpringOne Platform 2017 Ramiro Salas, Pivotal The concept of a service mesh represents a paradigm shift on application connectivity for distributed systems, with wide implications for analytics, policy and extensibility. In this talk, we will explain what a service mesh is, the power it brings to microservices, and its impact on Cloud Foundry and K8s, both separately and together. We will also discuss the implications for the traditional network infrastructure, and the shifting of responsibilities from L3/4 to L7, and our current thinking of using Istio to integrate all abstractions.

Microservices, Service Discovery and Registration have been heading towards the peak of inflated expectations on the Gartner Hype cycle for over the last year or so, but there has often been a lack of clarity as to what these are, why are they needed or how to implement them well. Service discovery and registration are key components of most distributed systems and service oriented architectures. In this session we will talk about what, why and how of service registration and discovery in distributed systems in general and OpenStack in particular. We will talk about some of the technologies that address this challenge like Zookeeper, Etcd, Consul, Mesos-DNS, Minuteman, SkyDNS, SmartStack or Eureka. We will also address how these technologies as well as existing OpenStack projects can be used to solve this problem inside OpenStack environments.

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.

Kubernetes users need to allow traffic to flow into and within the cluster. Treating the application traffic separately from the business logic allows presents new possibilities in how service to service traffic is served, controlled and observed — and provides a transition to intra cluster networking like Service Mesh. With microservices, there is a concept of both North / South traffic (incoming requests from end users to the cluster) and East / West (intra cluster) communication between the services. In this talk we will explain how Envoy Proxy works in Kubernetes as a proxy for both of these traffic directions and how it can be leveraged to do things like traffic shaping, security, and integrate the north/south to east/west behavior.

This document discusses cloud native microservices and key components for implementing them. It provides an overview of microservices principles and design patterns, and describes the cloud native landscape including containers, Kubernetes, service meshes like Istio, and other open source tools. It also discusses architectures like ONAP and considerations for deploying virtual network functions using microservices.

DevOps tools became very popular with the adoption of public cloud, but Operational teams now realize that their benefits can be extended to enterprise data centers. In reality, cloud native tools can help bridge public clouds and private data centers by enabling a common framework to manage applications and their underlying infrastructure components. In this session you’ll learn about the latest Cisco ACI integrations with Hashicorp Terraform and Consul to deliver a powerful solution for end-to-end on-prem and cloud infrastructure deployments.
