“净山-容器服务大促备战-北京meetup 0.1.pdf”主要探讨了阿里云容器服务在面对大规模促销活动(如双十一)时的备战策略和技术解决方案,涵盖了容器化、DevOps、弹性扩展、高可用性、安全、监控、全链路压测等多个关键领域。 在此次分享中,李斌提到了一系列挑战,包括极限并发流量的处理、人为失误导致的问题、系统的瓶颈、雪崩效应、单点失效、成本控制、用户体验、最终一致性、系统稳定性以及资源管理和利用效率等。针对这些问题,阿里云提供了丰富的备战工具箱,其中包括服务化、开发运维一体化、弹性计算、极致性能、高可用架构、全站上云、安全加固、人工智能、大数据和离线计算等技术手段。 容器服务是其中的核心,特别是在Kubernetes(K8s)平台上,它提供了自动化部署、扩展和管理容器化应用程序的能力。例如,阿里云的容器服务ACK (Apsara Container Service for Kubernetes) 和ASK (Serverless Kubernetes) 为用户提供了灵活且高效的服务。此外,通过ACR(Alibaba Cloud Container Registry)镜像服务,可以实现镜像的安全扫描、签名和全球自动分发,确保应用部署的安全性和一致性。 为了应对流量激增,阿里云强调了全链路压测的重要性,这有助于预测和观测系统的性能和容量。同时,他们通过引入边缘计算,实现了云边端一体化协同,优化了在线与离线任务的处理,利用ECS(Elastic Compute Service)、EBM(Elastic Bare Metal Service)、GPU、FPGA和ECI(Elastic Container Instance)等异构计算能力,提供高性能网络服务,如VPC、ENI、RDMA、SLB和DNS。 在存储方面,阿里云提供了EBS(Elastic Block Store)、NAS(Network Attached Storage)、CPFS(Cloud Parallel File System)和OSS(Object Storage Service)等高性能存储解决方案。对于数据库和大数据处理,文中提到了MySQL、Kafka、TiDB、Elasticsearch、TensorFlow、Spark和Flink等技术,这些都是云原生实时计算和人工智能的关键组件,尤其在处理百亿级实时样本和万亿维度模型时,能显著提升性能。 最后,全球化部署是另一个重要话题,阿里云构建了能够支持单集群万节点规模的云原生基础设施,以满足不同地区的业务需求,打造新的生态、算力和基石,助力企业实现全球化战略。 这份摘要揭示了阿里云在容器服务和云原生技术上的深度实践,为应对大规模促销活动提供了全面的技术准备和解决方案。

The OpenStack Foundation supported the creation of this book with plane tickets to Austin, lodging (including one adventurous evening without power after a windstorm), and delicious food. For about USD $10,000, we could collaborate intensively for a week in the same room at the Rackspace Austin office. The authors are all members of the OpenStack Foundation, which you can join. Go to the Foundation web site. We want to acknowledge our excellent host Rackers at Rackspace in Austin: Emma Richards of Rackspace Guest Relations took excellent care of our lunch orders and even set aside a pile of sticky notes that had fallen off the walls. Betsy Hagemeier, a Fanatical Executive Assistant, took care of a room reshuffle and helped us settle in for the week. The Real Estate team at Rackspace in Austin, also known as “The Victors,” were super responsive. Adam Powell in Racker IT supplied us with bandwidth each day and second monitors for those of us needing more screens. On Wednesday night we had a fun happy hour with the Austin OpenStack Meetup group and Racker Katie Schmidt took great care of our group. We also had some excellent input from outside of the room: Tim Bell from CERN gave us feedback on the outline before we started and reviewed it mid-week. Sébastien Han has written excellent blogs and generously gave his permission for re-use. Oisin Feeley read it, made some edits, and provided emailed feedback right when we asked. Inside the book sprint room with us each day was our book sprint facilitator Adam Hyde. Without his tireless support and encouragement, we would have thought a book of this scope was impossible in five days. Adam has proven the book sprint method effectively again and again. He creates both tools and faith in collaborative authoring at www.booksprints.net. We couldn’t have pulled it off without so much supportive help and encouragement.
