Introduction to System Design

System design is the process of creating a high-level plan or blueprint of a system that describes its structure, components, and interactions. It involves the design of both software and hardware aspects of the system.

As a senior engineer with 7 years of experience in full-stack development and a keen interest in Machine Learning (ML), you understand the importance of system design in building reliable and scalable ML applications. Just like ML models require careful planning and design, system design is crucial to ensure the smooth functioning of ML applications in production.

In system design, you need to consider various factors such as performance, scalability, reliability, security, and maintainability. These considerations are especially important when designing ML systems that handle large amounts of data and complex algorithms.

To give you an analogy, think of a basketball game. A well-designed system is like a smoothly functioning team on the basketball court. Each player has a specific role and interacts with other players to achieve a common goal - winning the game. Similarly, in system design, different components and modules work together to accomplish the desired outcome.

Let's take a look at a simple Java code snippet that demonstrates the concept of FizzBuzz:

1class Main {
2  public static void main(String[] args) {
3    for(int i = 1; i <= 100; i++) {
4      if(i % 3 == 0 && i % 5 == 0) {
5          System.out.println("FizzBuzz");
6      } else if(i % 3 == 0) {
7          System.out.println("Fizz");
8      } else if(i % 5 == 0) {
9          System.out.println("Buzz");
10      } else {
11          System.out.println(i);
12      }
13    }    
14  }
15}

This code prints numbers from 1 to 100, replacing multiples of 3 with "Fizz", multiples of 5 with "Buzz", and multiples of both 3 and 5 with "FizzBuzz". While this code is simple, it demonstrates the importance of designing the logic and structure of a program.

In the upcoming lessons, we will explore the key principles, components, and considerations in system design, as well as real-world case studies to help you develop a strong foundation in this important skill.

class Main {

  public static void main(String[] args) {

    // replace with your Java logic here

    for(int i = 1; i <= 100; i++) {

      if(i % 3 == 0 && i % 5 == 0) {

          System.out.println("FizzBuzz");

      } else if(i % 3 == 0) {

          System.out.println("Fizz");

      } else if(i % 5 == 0) {

          System.out.println("Buzz");

      } else {

          System.out.println(i);

      }

    }    

  }
