Bay Area Scheduler & Container Meetup 首届湾区调度&容器技术沙龙

Alibaba Group

<H2>Hello, Infrastructure Engineer!</H2>
Welcome to the very first event of the Bay Area Cluster Managment Meetup. Our goal is to share technical insights in this area, and get engineers connected. We are going to hold a series of activities in Alibaba's new office in Sunnyvale, and looking forward to your warm participation. If you are interested in sharing your experiences – either as speakers or as users – kindly contact us: alibabass@service.alibaba.com
欢迎大家参与湾区第一届调度&容器技术沙龙，我们希望能够为大家搭建一个技术交流的平台，让基础软件领域的工程师能有更多的机会去讨论、沟通、分享遇到的问题、新技术的出现和未来的发展。
本次活动我们邀请到了包括 Alibaba、LinkedIn、Mesosphere、Baidu AI Platform 近十位资深技术专家参与分享、讨论。
未来我们希望能够有更多的机会和大家在 Sunnyvale 见面，举办属于社区的技术沙龙。如果有兴趣一起筹办社区活动请来信至：alibabass@service.alibaba.com

1. The Challenges and Possibilities for Alibaba Cluster Management System 
阿里巴巴集群管理系统的机会和挑战
Sigma cluster management is the core infrastructure of Alibaba that manages most online services. Through our in-house developed PouchContainer technology, Sigma forms the basis for the goal of managing the computers of Alibaba data centers as one computer. In this talk, we will introduce the goal and positioning of Alibaba cluster management system and business scenarios. We will also share the problems we have solved, the insights of our architecture design, as well as the challenges and opportunities we face and our future plans for the Alibaba cluster management.
介绍阿里巴巴集群管理系统的目标定位，面临的场景，解决的问题，架构与特点，机会与挑战，未来规划
2.  Reliably Extending Kubernetes 
CRD (custom resource definition) is widely used to extend the behavior of kubernetes. It is important that the custom resources are managed reliably during any failures of crd controller such that a consistent state is maintained across failures. This talk will share the experiences we've gained: how to make leader election, design principle of namespaced CRD vs. clustered CRD, how to handle unexpected event from apiserver, etc.
3. The engine of Sigma: the Sigma scheduler  
阿里集群的大脑: sigma-scheduler
The sigma scheduler is a policy-rich, micro-topology-aware, workload-specific control plane component that places workload to the nodes. The scheduler needs to take into account individual and collective resource requirements, quality of service requirements, hardware/software/policy constraints, anti-affinity specifications, data locality, workload interference, and so on. The quality of the scheduler significantly impacts the overall cluster performance and utilization. In this talk, we will present the overall design principle of the sigma scheduler and its architecture. We will also explore some of the interesting functionalities that are designed to handle large scale low latency workload.
sigma-scheduler 是阿里巴巴集团内部的集群管理系统 Sigma 的调度器。它有着丰富的调度策略，能够理解复杂的拓扑结构，以及专门为内部业务场景深度优化。截至今日，sigma-scheduler 提供了一系列的功能以支撑阿里巴巴的业务需求——这包括细粒度资源划分、应用服务分层、拓扑规则限制 (taints, anti-affinity, node-selector)、locality 感知、以及预防应用间干扰等。sigma-scheduler 调度结果的好坏，直接影响了集群的性能和利用率。与时俱进，升级优化调度器，是我们工作的核心目标。 本次演讲我们将阐述 sigma-scheduler 的设计理念以及架构细节，并结合过去经验去探讨如何处理大规模场景。 
4. Kubernetes Container Runtime Interface and Containerd Integration
 Kubernetes容器运行时接口以及与containerd的集成
Docker is by far the most common container runtime used in production Kubernetes environments, but Docker’s smaller offspring, containerd, may prove to be a better option. Kubernetes container runtime interface (CRI) makes it possible for Kubernetes to support different container runtimes. This talk introduces the past, the present and the future of CRI, and how containerd is integrated with CRI.
目前，Docker仍是在Kubernetes生产环境中最常使用容器运行时，但是由Docker衍生出的更轻量的containerd可能是一个更好的选择。Kubernetes容器运行时接口(CRI)的设计使Kubernetes可以支持不同的容器运行时。本次演讲会介绍CRI的过去现在以及未来发展，并介绍containerd与CRI的集成工作的最新进展。
