CI/CD
和
FaaS
在
FaaS
平台中实施持续交付，几乎可以毫不费力地部署应用程序，甚至云服务商可能
会强制你使用持续交付 ：
y
专心创建一个
CD
管道，将你的应用程序（或者即使是为了验证概念原型）打包
为一个容器镜像，然后将它从本地开发环境部署到生产的
FaaS
环境。这将暴露
在使用
FaaS
过程中遇到的任何技术或组织问题。
y
如果你正在运行自己的
Kubernetes
平台，请将所有配置保存在版本控制系统中，
并通过
Terraform
或
Ansible
等
IaC
工具，自动化执行安装和升级操作。但是，
一般来说，使用云服务商提供的托管产品，会比自己搭建平台的性价比更高。
y
将所有应用程序的配置和元数据保存在版本控制系统中，例如，任何的服务发现
配置或者自定义的构建容器。其中，元数据还应该包括函数当前的最新版本。
y
确保你会为每个函数开放并收集核心的监控指标，例如内存使用量和执行时间。
y
在构建管道中进行压力测试时，可以尝试“合理地调整大小”：你需要将函数部
署到各种不同的容器
/
实例
/
运行时环境中，然后评估在各种环境中的吞吐量和
延迟。对
FaaS
应用程序进行压力测试通常会比较难，因为底层平台通常会根据
压力自动伸缩，但容器
/
实例
/
运行时的大小（包括
CPU
和内存）会影响单个和
所有函数的执行速度。
y
用你学习到的知识（和经验）来创建构建管道
—
例如，负载测试、安全测试和
失败
/
恢复测试。
y
虽然
FaaS
平台让你无须关注服务器（以及相关的安全补丁），但是不要忘记，你
还是需要发现并解决代码及相关依赖中的安全问题。 ...
