System Design Idea: Cloud Load Balancer Basics

Preamble

In a previous blog post, we examined the various types of load balancers and some intriguing areas like routing algorithm, SSL termination, and single point of failure. In this blog post, we’ll build on the theme and zoom in on cloud load balancers, which embodies some noteworthy design ideas. The core content in this blog post is based on the research papers published by Google and Microsoft (citations in the reference section). The designs have been well battle-tested in Google Cloud Platform and Microsoft Azure.
