Qualifications
Certifications
CQRS & Event Sourcing
Command Query Responsibility Segregation (CQRS), and Event Sourcing (ES), are powerful tools.
They can make the difference between an application that evolves, and remains competitive,
or one that stagnates and falls into obscurity. This course will discuss the reasons we use CQRS/ES,
what benefits it provides us, but also what it will cost us to use. We will see how CQRS/ES can impact
the scalability, consistency, and availability of our application. Most importantly we will learn about
one of the key techniques that is used in building modern Reactive Microservices.
