Cover the basics and learn how to design and develop distributed systems.

Become a Distributed Systems Professional

Gone are the days when monolithic applications were the norm. Most applications we use today are too complex for that type of construction. Instead, most applications that appear as a single unit are actually built as a collection of inter-operating but independent computational components. Developers are expected to have mastery over a programming language or two. Moreover, they should also know the basics of distributed systems.

In this module, we’ll learn what distributed systems are, and learn about the challenges unique to distributed systems. We’ll cover popular architectural patterns for achieving targets like replication and sharding. We’ll complete the module with a study of two popular distributed systems: Apache Spark and Apache Druid. With the knowledge gained through this module, we’ll be able to design and develop distributed systems. We’ll also develop an understanding of optimal design and architectural choices based on the application requirements.
