Chapter Summary

We used to live in a world where every time the business needed a new application, we had to buy a brand-new server. VMware came along and allowed us to drive more value out of new and existing servers. However, following the success of VMware and hypervisors came a newer, more efficient, and portable virtualization technology called containers. However, containers were complex and hard to implement until Docker came along and made them easy. WebAssembly is powering a third wave of cloud computing, but Docker and the container ecosystem are evolving to work with WebAssembly.
