Load Balancers

As we scale systems, it's essential to realize the impact of all the components in our systems and how they interact. For example, load balancers usually come into play once we scale beyond one server being able to serve requests reliably.

As you venture into more complicated architecture setups, there are a few things engineers sometimes don't understand when setting up consensus-based systems. Understanding quorums and fault tolerance are critical in understanding such systems.

Types of Memory

There is often a level of focus on the bigger picture when it comes to system design, but we often don't think about the underlying components in these systems. So let's chat about different levels of memory.

Understanding latency is essential in all parts of our systems, including registers, main memory, disk, and network.

Types of Encryption

Lets talk about encryption foundational topic in system design. Encryption involves converting human-readable plaintext into incomprehensible text, which is known as ciphertext and decrypting it back to plaintext again.
