Topic: CPU Burst: Get rid of unnecessary throttling, while achieving high CPU utilization and high application performance

Sharing time: December 9th, 11:20

Speakers: Cloud technical expert & Ding Tianchen, Alibaba Cloud technical expert

topic introduction: So far, many people's answer to the question of CPU throttling has always been to increase the CPU hard limit or turn off the CPU hard limit. However, this approach brings some new problems, such as potentially unmanageable performance impact, low CPU utilization, and high TCO (total cost of ownership). Recently, the feature of CPU Burst integrated into Linux 5.14 has become a new choice to solve this problem. We will introduce the kernel mechanism that enforces CPU limits, the content of the CPU Burst changes and their impact, and how to evaluate such changes. At the end of this sharing, you can know exactly whether you are using CPU Burst on your pods.

topics: EROFS, we currently doing for the container?

Share time: December 9th, 13:15

Speakers: Gao Xiang, Alibaba Cloud Technical Expert & Ge Xuyang, Alibaba Cloud Senior R&D Engineer

topic introduction: EROFS file system is a Linux read-only file system, which aims to save additional storage space while ensuring end-to-end performance. This file system has been officially upgraded since Linux 4.19. Previously, this file system was mainly used for embedded devices, but we found that there is also an urgent need for a read-only high-performance file system for container use cases. This topic will detail the new features we are developing for this new scenario.

Topic: How to migrate a Kubernetes cluster

Sharing time: December 9th, 14:05

Speakers: Gu Jing, Alibaba Cloud Senior R&D Engineer & Xie Yaoyao, Alibaba Cloud Technical Expert

issues Introduction: greater risk across multiple versions of the upgrade Kuberentes. Many customers choose to use cluster migration (that is, create a new high-version cluster, and then migrate applications from a low-version cluster to a high-version cluster) rather than upgrade the cluster. However, how to migrate clusters with zero downtime has become a major challenge. This sharing proposes a solution to the problem.

Forum: Network | Networking

Topic: Best Practice: Observability and root cause diagnosis of DNS failures in Kubernetes clusters

Sharing time: December 10, 11:20

Speaker: Xie Yuning, Senior R&D Engineer of Alibaba Cloud

topic introduction: In Alibaba Cloud's tens of thousands of Kubernetes clusters, DNS domain name resolution failure is one of the most common problems. The phenomenon of DNS resolution failures is also bizarre. We will introduce the observability and root cause diagnosis of DNS resolution failures in Kubernetes, including common DNS resolution failure scenarios in Kubernetes, the built-in observability plug-in of CoreDNS, how to diagnose CoreDNS exceptions through the dnstap protocol, and how to complete the client based on BPF Diagnosis of the root cause of side DNS abnormalities, etc.

Forum: Machine Learning + Data | MachineLearning + Data

topic: Fluid: Kubernetes native distributed data set coordinator and accelerator

Sharing time: December 10, 13:15

Speaker: Che Yang, Senior Technical Expert of Alibaba Cloud, Co-sponsor of Fluid Community

topic introduction: on the public cloud to run big data and artificial intelligence applications has become a new trend. However, accessing data in cloud decomposition environments such as S3, Google Cloud Storage, and Hadoop Distributed File System (HDFS) greatly challenges training performance and limits the scalability of computing. This sharing will introduce Fluid and how it can improve the performance of big data and artificial intelligence applications in Kubernetes. Participants will learn about the project’s motivation, architecture, latest features and user adoption, as well as the project’s roadmap and how new contributors can participate.

Forum: Runtime | Runtimes

Topic: Expanding container runtime operations in

Sharing time: December 10, 13:15

Speakers: Siyu, Alibaba Cloud technical expert, OpenKruise community leader

topic introduction: Normally, people can only use ordinary old data as the smallest unit of operation in Kubernetes. Some companies have hacked Kubelet's code in their clusters so that they can do more with containers. However, extending operations for runtime is indeed a wrong approach because it is not conducive to open source and community cooperation. Now, OpenKruise, one of the Cloud Native Computing Foundation sandbox projects, provides advanced features that can operate container runtimes in each original Kubernetes cluster. In this talk, we will introduce the usage of some functions in OpenKruise and how it works with Kubelet and CRI.

Sharing time: December 10, 14:05

Speaker: , Senior Technical Expert of Alibaba Cloud

topic introduction: With the continuous development of the cloud native ecosystem, Kubernetes has become a cloud operating system. At the same time, there are more and more voices that serverless is the development theme of cloud computing in the next decade, so how will Kubernetes better support this serverless scenario? How to use the Kubernetes ecosystem to better integrate the two? This discussion mainly introduces how to achieve technological breakthroughs within Alibaba and how to achieve large-scale migration of existing applications.
