Docker / Kubernetesによる Cloud Nativeな開発と未来 - Developers Boost at 12/15 / devboost-k8s-cn

Developers Boost～U30エンジニアの登竜門～

近年Dockerから始まったコンテナ技術やKubernetesは急激に普及し、大手クラウドプロバイダー3社（GCP、Azure、AWS）がマネージドKubernetesサービスをリリースしたことからも、コンテナプラットフォームとしてデファクトスタンダードとなったことを物語っています。
また、Linux FoundationのExecutive DirectorでもあるJim Zemlin氏が「Kubernetes is becoming the Linux of the cloud」とも語っています。

Kubernetesはインフラエンジニアのためだけではなく、ソフトウェアエンジニアが利用するものでもあります。
このセッションでは、今後のCloud Nativeな開発に必要不可欠なKubernetesについて説明し、様々なエンジニアがKubernetesをベースとした開発で得られるメリットと未来について語ります。

     page 013 Cloud native technologies empower organizations to build and run scalable applications in modern, dynamic environments such as public, private, and hybrid clouds. Containers, service meshes, microservices, immutable infrastructure, and declarative APIs exemplify this approach. These techniques enable loosely coupled systems that are resilient, manageable, and observable. Combined with robust automation, they allow engineers to make high-impact changes frequently and predictably with minimal toil. The Cloud Native Computing Foundation seeks to drive adoption of this paradigm by fostering and sustaining an ecosystem of open source, vendor-neutral projects. We democratize state-of-the-art patterns to make these innovations accessible for everyone. CNCF Cloud Native Defenition v1.0, CNCF, 2018-11-28 (https://github.com/cncf/toc/blob/master/DEFINITION.md)
