我最近开始了与云相关技术的旅程。我正在尝试了解基础知识，以便能够为我面向物联网的公司中的基本云设置奠定基础。
在浏览 Internet 时，我偶然发现了以下两组开源项目：
我试图理解：
Cloud stack and Open stack are open source softwares designed to manage, deploy virtual machines and networks which can deliver cloud services. Mainly these provide Infrastructure as a Service (IaaS). There are alot of comparisons on the internet on these two. So these softwares needs to be intalled on your hardware and maintain it and you provide a cloud service from it. When it comes Amazon AWS it is a readily available service where you don't do installations or maintain hardware, you just take service from them.
WSO2 and MuleSoft are different from above two and they are software platforms where several products(such as ESB). Both provide cloud platform facilities to deploye their products.
We cannot say which one to use but base on your requirements you may choose one or two (WSO2 products deployed on Amazon AWS or WSO2 products deployed on CloudStack VM's). Since you are willing to set up Internet of things, i think you may need to refer about products provided by above providers. Following source [1] will give you an idea about Iot platform setup by several free open source WSO2 products.
