云计算介绍 当用户能够通过互联网方便的获取到计算、存储等服务时，我们比喻自己使用到了“云计算”，云计算并不能被称为是一种计算技术，而更像是一种服务模式。每个运维人员心里都有一个对云计算的理解，而最普遍接受的是NIST(美国国家标准与技术研究院)的定义： 云计算是一种按使用量付费的服务模式，这是一种能够提供可用的、便捷的、按需求的网络访问模式，计算共享池能够快速的为用户提供网络、服务器、存储、应用软件及其他服务，并且只需要花费很少的管理时间。 服务层次 NIST还针对于云计算的服务模式提出了3个服务层次： Iaas：提供给用户的是云计算基础设施，包括CPU、内存、存储、网络等其他的资源服务，用户不需要控制存储与网络等基础设施。 Paas：提供给用户的是云计算中的开发和分发应用的解决方案，用户能够部署应用程序，也可以控制相关的托管环境，比如云服务器及操作系统，但用户不需要接触到云计算中的基础设施。 Saas：提供给用户的是云计算基础设施上的应用程序，用户只需要在客户端界面访问即可使用到所需资源，而接触不到云计算的基础设施。 、 OpenStack项目 OpenStack官方网站：https://www.openstack.org/ Openstack项目的版本按照ABCDEFG……的顺序发布，每6个月更新一次。

Add RabbitMQ distributed tracing to Zipkin

由 泄露秘密 提交于 2021-02-18 12:11:24
问题 We have been playing around with Brave(Java implementation of Zipkin) and successfully added tracing for REST and database calls. We would like to also add RabbitMQ to the tracing and would like some thoughts from anyone who may have had similar experiences that they could share. We have tried to find some stuff online but can't seem to find an interceptor we could add to our rabbit implementation. Can you recommend anything? Thanks in advance. 回答1: The best way to ask for a feature is using

Rabbitmq File Descriptor Limit

由 醉酒当歌 提交于 2021-02-17 20:27:35
问题 Rabbitmq documentation says that we need to do some configuration before we use it on production. One of the configuration is about maximum open file number (which is an OS parameter). Rabbitmq server we use is running on Ubuntu 16.04 and according to resources I found on web, I updated the number of open files as 500k. When I check it from command line, I get the following output: root@madeleine:~# ulimit -n 500000 However when I look at the rabbitmq server status, I see another number. root
