Reactive Architecture: Building Scalable Systems
|
Learn how to design and build scalable systems using reactive architecture. Explore the fundamentals of event-driven, non-blocking applications that can handle high loads and scale dynamically in modern distributed environments.
At a Glance
Building Reactive Systems requires a balance between Consistency and Availability. This course will explain why that balance exists.
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.
