As the name suggests, Systems design is basically the process of designing a System or Software to solve a particular real life problem like how to design a messaging broker like Kafka. It involves requirement gathering like how the system should behave, does it need to support multiple consumers etc?

It also involves high level design and low level design and you will talk about modules, architecture, components, interface, and data for a system based on a specific set of requirements. It can also refer to the process of defining, developing, and designing systems. 

These designs have to satisfy the specific needs of a company or an organization.

As a Software Engineer or System designer, you have to make use of all the different modeling languages for expressing the information and knowledge in the structure of a system. This system has to be defined by a consistent set of rules and definitions. 

It can also be defined in textual or graphical modeling languages like the Unified Modeling Language, UML, Flowchart, Business Process Modeling Notation, and Systems Modeling Language.

There are also different types of design methods that you can make use of. They include Architectural Design, Logical Design, and Physical Design.

The list also includes best system design interview courses from Udemy, Educative, ByteByteGo, DesignGuru, Exponent, ZTM Academy, and other popular online platforms. Also, here is a nice System Design Template from Design Guru to quickly revise essential System design concepts for interviews.
