The Fantastic Four of System Design

Scalability, Availability, Reliability, and Performance. They are the most critical components to crafting successful software systems.

Let’s look at each of them with implementation techniques:

• Scalability

  Scalability ensures that your application can handle more load without compromising performance.

• Availability

  Availability makes sure that your application is always ready to serve the users and downtime is minimal.

• Reliability

  Reliability is about building software that consistently delivers correct results.

• Performance

  Performance is the ability of a system to carry out its tasks at an expected rate under peak load using available resources.
