不懂程序猿的世界 尤其是支付宝技术团队的程序猿
本以为程序猿已经是世界上最奇怪的工种，格子衬衫、随身带键盘、背双肩包、还秃顶，没想到，还有一种有“自虐”倾向的程序猿物种——支付宝技术团队。
对于他们而言，分成红蓝两队阵营，通过仿真环境模拟天灾人祸，上演“矛盾”之战，比网吧团战开黑来的更刺激。
从2016年开始，支付宝内部建立“红蓝对抗”机制，由蓝军寻找系统应用及架构上的脆弱点，牵引红军升级防控能力，每周“突袭”外加一年两大考，要求技术小哥哥们必须时刻绷紧神经。通过这种全栈级别的大型技术攻防演练，来检验并提升技术团队应急处理能力和风险意识，以进一步把控技术风险。
在这场技术攻防演练中，支付宝技术团队的程序猿们“玩”得不亦乐乎。蓝军成立两个月后，便推出了字节码级别的故障注入系统Awatch，实时侵入运行中的业务系统。同时，红军也积极建设防控体系，针对性地推出实时核对平台，做到稳定的分钟级核对异常发现能力。另外，各个业务域也研发了相应的核对系统，共同建立起稳固防线。
但由于大部分的故障场景主要是各个业务方提供的，更深层的隐患仍未被发现，蓝军意识到必须得自己主动去“找事儿”，于是在今年3月推出故障场景挖掘平台，最高能够在5分钟内产生500+的故障场景。
持续应急压力下，红军的程序猿们开展“故障自愈”架构体系升级及能力建设，配合蓝军研发了“无损”攻防体系以及相匹配的度量平台，让这场“攻防游戏”的结果数据可视化。
目前，对抗赛已经成为常态，保持每周200+故障场景的节奏运作。蓝军实时、随地、无差别地攻击，确实让红军的程序猿们费了不少心思。有趣的是，红军会在演练前举办拜关公的仪式，以求关公庇佑，还曾在一次周末突袭中感概“这次预期外的故障攻击是最真实的应急锻炼！”
从最开始简单设立技术质量团队和运维团队的青铜时代，到组建SRE团队（Site Reliability Engineer）的钻石时代，支付宝系统的稳定性逐步进阶，蚂蚁金服的技术风险也迅速发展，红蓝军对抗赛起到了关键性作用。 未来，蚂蚁金服SRE团队希望在技术风险防控方面做到5个9的能力，即99.999%，且任意故障在5分钟之内解决，并让技术风险防控具备智能特性，减少人工干预。
经过三年实践，全栈级技术攻防演练已经沉淀出一整套成熟的风险防控体系。现在正式对外开放，包括容灾应急平台、全链路压测、资金安全监控、变更管控、巡检平台以及黑屏运维管控等产品，已在蚂蚁金融科技官网（tech.antfin.com）逐步上线。
