Programming Reactive Systems

About this Course

Reactive programming is a set of techniques for implementing scalable, resilient and responsive systems as per the Reactive Manifesto. Such systems are based on asynchronous message-passing, and their basic building-blocks are event handlers. This course teaches how to implement reactive systems in Scala and Akka by using high-level abstractions, such as actors, asynchronous computations, and reactive streams.
You will learn how to:

- use, transform and sequence asynchronous computations using Future values
- write concurrent reactive systems based on Actors and message passing, using untyped Akka and Akka Typed
- design systems resilient to failures
- implement systems that can scale out according to a varying workload
- transform and consume infinite and intermittent streams of data with Akka Stream in a non-blocking way
- understand how back-pressure controls flows of data

Introduction, Recap and Asynchronous Programming

This module shows you how to get started with the course. After setting up your machine to work on and to submit assignments, it will provide you with a recap of the basics of the Scala language. Finally, you will encounter the first topic of the course, asynchronous programming with Futures.

Frequently Asked Questions

When will I have access to the lectures and assignments?
Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:
The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.
The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
What will I get if I purchase the Certificate?
When you purchase a Certificate you get access to all course materials, including graded assignments. Upon completing the course, your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile. If you only want to read and view the course content, you can audit the course for free.
Is financial aid available?
Yes, Coursera provides financial aid to learners who cannot afford the fee. Apply for it by clicking on the Financial Aid link beneath the "Enroll" button on the left. You’ll be prompted to complete an application and will be notified if you are approved. Learn more.
