Stateless and Stateful Systems
Explore the concepts of stateless and stateful systems within distributed computing. Understand how stateless systems simplify design and scaling by treating nodes identically, while stateful systems handle data with added complexity. This lesson guides you through their characteristics, benefits, and real-world applications to inform efficient distributed system architecture.
We can say that a system belongs in one of the two following categories:
- Stateless systems
- Stateful systems
Stateless system
A stateless system maintains no state of what happened in the past and performs its capabilities purely based on the inputs we provide to it.
Examples
A contrived stateless system receives a set of numbers as input, calculates their maximum, and returns it as a result. These inputs are either direct or indirect. Direct inputs are inputs that ...
