Since the Kubernetes 1.0 release in July, we’ve seen tremendous adoption by companies building distributed systems to manage their container clusters. We’re also been humbled by the rapid growth of the community who help make Kubernetes better everyday. We have seen commercial offerings such as Tectonic by CoreOS and RedHat Atomic Host emerge to deliver deployment and support of Kubernetes. And a growing ecosystem has added Kubernetes support including tool vendors such as Sysdig and Project Calico.
With the help of hundreds of contributors, we’re proud to announce the availability of Kubernetes 1.1, which offers major performance upgrades, improved tooling, and new features that make applications even easier to build and deploy.
- **Substantial performance improvements** : We have architected Kubernetes from day one to handle Google-scale workloads, and our customers have put it through their paces. In Kubernetes 1.1, we have made further investments to ensure that you can run in extremely high-scale environments; later this week, we will be sharing examples of running thousand node clusters, and running over a million QPS against a single cluster.
-->
- **实质性的性能提升** ：从第一天开始，我们就设计了 Kubernetes 来处理 Google 规模的工作负载，而我们的客户已经按照自己的进度进行了调整。
在 Kubernetes 1.1 中，我们进行了进一步的投资，以确保您可以在超大规模环境中运行；
本周晚些时候，我们将分享运行数千个节点集群，并针对单个集群运行超过一百万个 QPS 的示例。
<!--
- **Significant improvement in network throughput** : Running Google-scale workloads also requires Google-scale networking. In Kubernetes 1.1, we have included an option to use native IP tables offering an 80% reduction in tail latency, an almost complete elimination of CPU overhead and improvements in reliability and system architecture ensuring Kubernetes can handle high-scale throughput well into the future.
-->
- **网络吞吐量显着提高** : 运行 Google 规模的工作负载也需要 Google 规模的网络。
- **Horizontal pod autoscaling (Beta)**: Many workloads can go through spiky periods of utilization, resulting in uneven experiences for your users. Kubernetes now has support for horizontal pod autoscaling, meaning your pods can scale up and down based on CPU usage. Read more about [Horizontal pod autoscaling](http://kubernetes.io/v1.1/docs/user-guide/horizontal-pod-autoscaler.html).
-->
- **水平 Pod 自动缩放 (测试版)**：许多工作负载可能会经历尖峰的使用期，从而给用户带来不均匀的体验。
Kubernetes 现在支持水平 Pod 自动缩放，这意味着您的 Pod 可以根据 CPU 使用率进行缩放。

<!--
- **HTTP load balancer (Beta)**: Kubernetes now has the built-in ability to route HTTP traffic based on the packets introspection. This means you can have ‘http://foo.com/bar’ go to one service, and ‘http://foo.com/meep’ go to a completely independent service. Read more about the [Ingress object](http://kubernetes.io/v1.1/docs/user-guide/ingress.html).
- **Job objects (Beta)**: We’ve also had frequent request for integrated batch jobs, such as processing a batch of images to create thumbnails or a particularly large data file that has been broken down into many chunks. [Job objects](https://github.com/kubernetes/kubernetes/blob/master/docs/user-guide/jobs.md#writing-a-job-spec) introduces a new API object that runs a workload, restarts it if it fails, and keeps trying until it’s successfully completed. Read more about the[Job object](http://kubernetes.io/v1.1/docs/user-guide/jobs.html).
- **New features to shorten the test cycle for developers** : We continue to work on making developing for applications for Kubernetes quick and easy. Two new features that speeds developer’s workflows include the ability to run containers interactively, and improved schema validation to let you know if there are any issues with your configuration files before you deploy them.
- **Rolling update improvements** : Core to the DevOps movement is being able to release new updates without any affect on a running service. Rolling updates now ensure that updated pods are healthy before continuing the update.
-->
- **滚动更新改进** : DevOps 运动的核心是能够发布新更新，而不会影响正在运行的服务。
滚动更新现在可确保在继续更新之前，已更新的 Pod 状况良好。

Today, we’re also proud to mark the inaugural Kubernetes conference, [KubeCon](https://kubecon.io/), where some 400 community members along with dozens of vendors are in attendance supporting the Kubernetes project.
> “We are betting our major product, Tectonic – which enables any company to deploy, manage and secure its containers anywhere – on Kubernetes because we believe it is the future of the data center. The release of Kubernetes 1.1 is another major milestone that will create more widespread adoption of distributed systems and containers, and puts us on a path that will inevitably lead to a whole new generation of products and services.” – Alex Polvi, CEO, CoreOS.
> “Univa’s customers are looking for scalable, enterprise-caliber solutions to simplify managing container and non-container workloads in the enterprise. We selected Kubernetes as a foundational element of our new Navops suite which will help IT and DevOps rapidly integrate containerized workloads into their production systems and extend these workloads into cloud services.” – Gary Tyreman, CEO, Univa.
