About This Course

Building Reactive Systems requires a balance between Consistency and Availability. This course will explain why that balance exists. We will discuss the CAP theorem as well as the Laws of Scalability that dictate what is possible to achieve when we build distributed systems. We will also introduce some techniques we can use to strike the right balance. All of this will be grounded in a discussion which starts first in the real world.

What will I get after passing this course?

You will receive a completion certificate.
