Cache Strategies with Best Practices

Problem statement
It's expensive to retrieve remote data in many data-intensive and latency-sensitive online services. A cache is widely used as a common practice to speed up the service. It's challenging to build an efficient cache and some bad cache implementations may break the system even more.

Proposal
This is a technical deep-dive about a set of cache strategies with real examples. We will describe Cache Item strategies, Multiple Cache TTL strategies, and Cache warm-up strategies. We'll explain how they significantly improve system performance while maintaining cache efficiency and increase availability. We will also share our practices in adopting those strategies.
