CNCF Introduction - Feb 2018

  1. 1. CNCF - Introduction @ India Open Stack User Group Meeting (Pune & Bangalore) February 2017 by Sajid Akthar – Open Stack Ambassador Krishna Kumar – CNCF Ambassador The materials in the presentation are from public websites and it is used here for just educational purposes. Thanks to the respective authors for sharing 
  2. 2. Contents • What & Why? • Cloud Native Software Stacks! • The people behind! • How to engage/contribute?
  3. 3. Who we are CNCF is an open source foundation created to make cloud-native computing universal. We promote the use of dynamically- orchestrated containerized applications in a microservices architecture on any public, private or hybrid cloud. Cloud-native technologies enable software developers to build great products, allowing businesses to move faster than ever before. https://www.cncf.io/
  4. 4. What is cloud native …???? Cloud-native applications are purpose built for the cloud model. These applications—built and deployed in a rapid cadence by small, dedicated feature teams to a platform that offers easy scale-out and hardware decoupling—offer organizations greater agility, resilience, and portability across clouds. Pivotal At the heart of "cloud-native" lie Linux, Linux containers, and the concept of applications assembled as microservices in containers. Indeed, the Linux Foundation launched the Cloud Native Computing Foundation. But cloud-native means a lot more than implementing Linux clusters and running containers. It's a term that recognizes that getting software to work in the cloud requires a broad set of components that work together. It also requires an architecture that departs from traditional enterprise application design. . Charles -informationWeek Here’s how a blog on IBM’s developer web site distinguishes the two adjectives Cloud-Native and Cloud-Enabled: You can say that a cloud-enabled application is an application that was moved to cloud, but it was originally developed for deployment in a traditional data center. Some characteristics of the application had to be changed or customized for the cloud. On the other hand, a cloud-centric application (also known as cloud-native and cloud-ready) is an application that was developed with the cloud principles of multi- tenancy, elastic scaling and easy integration and administration in its design. 12 factors (One of the solid principle for Cloud Native Software Architecture) Codebase One codebase tracked in revision control, many deploys Dependencies Explicitly declare and isolate dependencies Config Store configuration in the environment Backing Services Treat backing services as attached resources Build, release, run Strictly separate build and run stages Processes Execute the app as one or more stateless processes Port binding Export services via port binding Concurrency Scale out via the process model Disposability Maximize robustness with fast startup and graceful shutdown Dev/prod parity Keep development, staging, and production as similar as possible Logs Treat logs as event streams Admin processes Run admin/management tasks as one-off processes
  5. 5. Graduation Criteria CNCF projects can be at inception, incubating or graduated stage. View the CNCF graduation criteria and the current status of each project.
  6. 6. 1) Kubernetes: Automating deployment, scaling, and management of containerized applications 2) Prometheus: Monitoring, metrics, alerting, visualizing, queries, integration 3) OpenTracing: Distributed tracing. Libraries available for various languages 4) Fluentd: Fluentd allows you to unify data collection and consumption for a better use and understanding of data. 5) GRPC: Define your service using Protocol Buffers, a powerful binary serialization toolset and language 6) Conainerd: An industry-standard container runtime with an emphasis on simplicity, robustness and portability. 7) Rkt: pod-native container engine for Linux. It is composable, secure, and built on standards. 8) CNI: Container Network Interface - networking for Linux containers 9) Envoy: EDGE AND SERVICE PROXY 10) Jaeger: Jaeger, inspired by Dapper and OpenZipkin, is a distributed tracing system released as open source by Uber 11) Notary: A project that allows anyone to have trust over arbitrary collections of data 12) TUF: The Update Framework specification 13) Vitess: A database clustering system for horizontal scaling of MySQL 14) Linkerd: ServiceMesh - A transparent proxy that adds service discovery, routing, failure handling, and visibility 15) CoreDNS: DNS & Service Discovry - chains plugins. Each plugin performs a DNS function, such asKubernetes service discovery, Prometheus metricsor rewriting queries. 16) Rook: File, Block, and Object Storage Services for your Cloud-Native Environments • New proposals: 1) NATS: https://github.com/cncf/toc/pull/81 2) OPA: Consistent policy expression and enforcement mechanism and common toolset. https://github.com/cncf/toc/pull/71 3) SPIFFE: Service identity (LOAS) bringing together all the pieces to recreate the environment https://github.com/cncf/toc/pull/68
  7. 7. Kubernetes – The soul of CNCF….. https://github.com/kubernetes/steering http://blog.kubernetes.io/2017/12/kubernetes-19-workloads-expanded-ecosystem.html Kubernetes Office hours - https://github.com/kubernetes/community/blob/master/events/office-hours.md
  8. 8. Related projects: OCI (Open Container Initiative): Established in June 2015 by Docker and other leaders in the container industry, the OCI currently contains two specifications: the Runtime Specification (runtime-spec) and the Image Specification (image-spec). The Runtime Specification outlines how to run a “filesystem bundle” that is unpacked on disk. At a high- level an OCI implementation would download an OCI Image then unpack that image into an OCI Runtime filesystem bundle. Istio: An open platform to connect microservices. Istio essentially provides developers with a single service mesh that provides the monitoring services to then implement the necessary load balancing, flow-control and security policies they need to keep their applications running even if the network isn’t reliable. Istio also allows developers to authenticate and secure the communications between different applications using a TLS connection (which means the developer doesn’t have to manage certificates, for example). Google, IBM and Lyft launch Istio, an open- source platform for managing and securing microservices MetaParticle: Metaparticle enables you to focus on your code, while allowing you to treat your architecture as code as well. Metaparticle works by defining service patterns, which you can instantiate via simple code. This code contains both the definition of your architecture as well as the implementation of the service itself. This work was an experimental by Brendanburns, Kuberntes Creator.
  9. 9. CNCF taking up Serverless Computing….. CNCF created the Serverless Working Group to ‘explore the intersection of cloud native and serverless technology.’ The first output of the group was creation of serverless landscape, which is available. https://www.cncf.io/blog/2018/02/14/cncf-takes- first-step-towards-serverless-computing/

  15. 15. CNCF Community • Slack - https://slack.cncf.io/ • Twitter - https://twitter.com/cloudnativefdn • Mailing Lists - https://lists.cncf.io/g/main • Public presentations - https://github.com/cncf/presentations • Marketing Committee (Requires Membership) • Project Statistics - https://cncf.biterg.io/app/kibana#/dashboard/Overview?
  16. 16. Source Code: Git Hub One of the prominent contributions to the open source community is in the form of source code to existing projects. https://github.com/cncf https://github.com/kubernetes/kubernetes To get start attend the SIG to start code contribution: https://github.com/kubernetes/community/blob/master/sig-list.md And so on.. For each project has its own repo, communities….. Creating a new project • If you have a new project to propose to CNCF please go through the document shown in the link https://github.com/cncf/toc/blob/master/process/project_proposals.adoc • You start with proposing the project to the Technical Oversight Committee (TOC) and based on the vote in TOC it may get accepted to the inception, incubation or graduate stage. The process is the same for both existing projects which seek to move into the CNCF, and new projects to be formed within the CNCF. To graduate from inception or incubation status, the project must meet the criteria as shown in the link https://www.cncf.io/projects/graduation-criteria Note: To get start: Documents are an essential part of the any software development process but most often ignored. These may include user guides, architectures, presentations, etc. Governance (Similar to most of the projects) • Kubernetes:https://github.com/kubernetes/community/ blob/master/governance.md • Prometheus:https://prometheus.io/governance/
