Google XML Document Format Style Guide Version 1.0 Copyright Google 2008 Introduction This document provides a set of guidelines for general use when designing new XML document formats (and to some retroactive changes in existing designs. When participating in the creation of public or private document format designs, the guidelines may be helpful but should not control the group consensus. This guide is to express rich text. A document that includes embedded content in XHTML or some other rich-text format, but also contains purely machine-interpretable portions, SHOULD follow this style guide for the

任何状态。如果无需发布新代码就可以理解任何新的或怪异的状态，那么 系统就具备可观测性。 什么是可观测性？ 可观测性开源产品 每种方案都有特定的、自定义的 步骤来生产和转移符合后端存储 的遥测(Telemetry)数据，这就带 来了工具或者厂商的绑定性。 为了解决“厂商锁定问题”，监控和可观测性社区过去创建了很多开源项 目，比如OpenTracing和OpenCensus，这些标准允许用户实时收集遥测

messaging systems. JMS is only available to clients running Java. JMS does not define a standard wire format - it only defines a programmatic API so JMS clients and servers from different vendors cannot directly Stomp is a very simple text protocol for interoperating with messaging systems. It defines a wire format, so theoretically any Stomp client can work with any messaging system that supports Stomp. Stomp Apache ActiveMQ Artemis. AMQP is a specification for interoperable messaging. It also defines a wire format, so any AMQP client can work with any messaging system that supports AMQP. AMQP clients are available
